August has been a rainy and relatively quiet month here at Cloudbridge.  We are quite happy to have welcomed Río Dante Barrantes Para as our new science coordinator, his knowledge of local fauna is a constant source of inspiration.  And of course, we wish the best to our previous coordinator, Paula Pebsworth.  We feel quite honored to have had Paula with us for the time that we did, and wish her the best of luck with future endeavors!  Thank you for everything, Paula : )

Rio has been able to familiarize himself with all the different parts of Cloudbridge Nature Reserve. Here he visits Catarata Don Victor, in Cloudbridge North.

For some time now, Dr. Michael Mooring has been collaborating with the National Park Service to monitor the presence of mammals, especially carnivores such as felines, in the Talamanca mountains. Cloudbridge has also been helping with this exciting project, and we were very happy this month to have the opportunity to meet with Dr. Mooring and others to establish clear guidelines for the collaboration. Later in the month, a team from Cloudbridge made the trek from San Jerónimo up to Chirripó, and back again along the main (San Gerardo) trail, to change the batteries and SD cards and in some cases even replace cameras that were not functioning.

The trail from San Jerónimo goes through the Sabana de los Leones, one of Chirripó National Park´s distinctive features.
“Los Crestones” are another salient feature of Chirripó National Park. This picture shows “la Aguja (the needle)”, the Creston that stands alone.
Valeria and Greivin were able to enjoy the diverse and whimsical landscapes that attract people from around the world to this beautiful National Park.
Though the objective of the trak was to check on the camera traps and change the SD cards, we were also fortunate to have a moment to relax and enjoy ourselves.

We are very pleased to be able to continue supporting and collaborating with the local recycling program. With the amount of visitors at Chirripó National Park, there is always recycling to be sorted and smashed!

It is always sad when our longstanding researchers or volunteers leave us. This picture was taken on Justin and Philip´s last night at Cloudbridge. We miss you guys : ) Of course, we are also thankful and have been enjoying the company of the new participants who have joined our team.

Hanna does a great selfie, with the lovely group who have been here at Cloudbridge behind her.

Staff, researchers and Volunteers

My name is Rio Dante, I’m currently the scientific coordinator at Cloudbridge Reserve and am finishing my Tropical Biology degree at the National University of Costa Rica. I’ve been a Biologist at heart since I was a child and would explore the jungles looking for all kinds of animals like snakes, bats, snakes etc. While also always trying to protect the environment as much as possible.

Hi! My name is Elías Calderon Morales, I am a 22 year-old student at the National University of Costa Rica. I am studying Sustainable Tourism Management, and am happy to be able to do my practicum at Cloudbridge Nature Reserve.

My name is Hanna Höffner and I am 19 years old. Last year I finished Highschool in Germany and started working to collect money for travelling. The last four weeks I was here at Cloudbridge as a Volunteer. My dream is to become a researcher and that’s why this Nature reserve was the best choice. I enjoyed the nature and going on Surveys so much, that I really want to keep working for my dream. Here in Cloudbridge my favourite animals I saw were the Emerald Toucanets, the Coatis, the Butterflies, the fireflies and the Milksnake. Everyone here was very open, nice and friendly to me and I am so glad to had the possibility to be part of this team for a month.

  • This summer has been devastating in the “natural” disasters that have affected so many countries around the world, from flooding and storms to fire and heat waves. This only serves to remind us all of the urgency with which we need to address the climate crisis. This month, the newly published IPCC report makes this crystal clear, with what has been called a code red for humanity. This New York Times piece highlights 5 takeaways from the report.
  • The longstanding drought in the Western United States is reaching a critical point, as demonstrated in these excellent articles from The Atlantic and The New York Times.
  • To face these unprecedented situations, solutions may come from a different approach than what many people are used to, for example, in Spain there is a push to grant the Mar Menor with personhood status.
  • To end on a positive note, Costa Rica provides an inspiring blueprint of how to achieve better health outcomes with limited resources.

In July 2020, Cloudbridge ́s executive director completed the Global Virtual Climate Reality Training. One year later, she was able to participate in the Latin American training, as a mentor. She greatly enjoyed the experience of moderating the discussions had by her group, who consisted of smart, engaged participants from Costa Rica and Panama. The next virtual global training will be taking place in October. If you would like to learn more please visit their website.

Cloudbridge was happy to provide a space for the field section of a recent Wilderness Safety Course held by Montaña Verde Ecological Association. Participants learned how to be prepared and safety conscious for their time in the mountains of Costa Rica. The instructor, Santiago Montoya, is an avid nature lover who has been teaching these skills for many years.

Participants in the wilderness safety course enjoy a rest at the Mirador of Cloudbridge Nature Reserve.
Participants built a stretcher with materials they had on hand and carried their team-mate in this emergency preparedness simulation.
The beautiful colors of the lotus flower are just one of the attractions found at Jardines Secretos.

The whole Cloudbridge group was able to enjoy a delicious Sunday-morning brunch at Jardines Secretos, in San Gerardo. Not only was the food delicious, but the scenery is spectacular. Highly recommended!

Tree-planting is one of our favorite activities here at Cloudbridge! We were delighted to have Paula´s son Bryce, and one of our neighbors from San Gerardo join in the tree-planting activity this month : )

After planting some trees, Nonie and Amada took a moment to enjoy the river : )
Another fun activity this month was a nice tree-tour with Edgar. Here, he is delighted to find a Kioro tree in the primary forest at Cloudbridge : )

Hello! my name is Justin Philbois, from France. I’m here to study the diversity of beetles between the different part of the forest.
I’ve always been very interested in all invertebrates and I think that people are afraid of them because we don’t know them very well. I’m here to remedy that!

Justin looks at beetles that have fallen into his Japanese umbrella.

Hello! My name is Alexandra and I came to Cloudbridge from Dakar, Senegal because I wanted to learn more about wildlife research and the cloud forest. I am an Environmental Science and Public Health student at the University of California, Los Angeles and I am especially interested in the intersection between environmental and human health. I am so happy to be here and am learning so much already! 🙂

After his time at Cloudbridge, Nicholas Hess travelled around Costa Rica before returning home. Though this picture was not taken at Cloudbridge, Nicholas has kindly allowed us to share it here. Check out more of his photography at Photo credit: Nicholas Hess

It has been a wonderful privilege and a pleasure to have Dr. Paula Pebsworth be our science coordinator for the last six months. We are quite sad to see her return to the USA, for personal reasons. However, we are very happy that she will remain a long-term member of Cloud Forest Conservation Alliance. And of course, we are grateful for all of Paula´s enthusiasm and warmth that she brought to her position with us. We wish you all the best, Paula!

We are also excited to receive our new science coordinator, Rio Dante Barrantes Para. Welcome to the team, Rio!

Paula´s last potluck…until you return!

Hi, my name is Jared Ward, from the United States. I’ve worked in supply chain consulting for the past 10 years, and came to Cloudbridge as a research assistant to learn more about field research and conservation. It’s been a great experience learning various research techniques, being surrounded by nature on a daily basis, and working with such a great group of people from across the globe. I’m looking forward to applying the knowledge I’ve gained over the past months to a career in environmental sustainability.

Jax Frink is a visual journalist from Eugene, Ore., United States, with a passion for telling stories centered around human rights, social justice and environmental issues. They explore the human connection with their environment and roles within society, telling stories of people, place and time.

My name is Nicholas Hess. I’ve spent my time at Cloudbridge recording fluorescence in the amphibian species here. I am very interested in all things herpetology, especially finding snakes. I am also a wildlife photographer and have been having an amazing time here!

This month we have also continued with some ongoing research collaboration with Dr. Michael Mooring, evaluating carnivores in Chirripó National Park using camera traps. Our researchers took advantage of the trip to visit the summit, as well : )

As with any time of year, it is fascinating to see what is flowering and fruiting. This Gesneriaceae still hasn´t been named, though botanists have identified it as a separate species from Drymonia macrantha, with which it has been confused in the past.

Another great fruit we have been seeing around is the aguacatillo, or “little avocado”, which is one of the Quetzal´s favorite foods!
The “poró criollo” (Erythrina berteroana) has also been impressing with it´s spiky flowers. This native relative to the well-known Poró gigante (Erythrina poeppigiana) has edible flowers and produces beautiful seeds that are used in handicrafts.

Though the Covid-19 pandemic has put a pause on San Gerardo´s great recycling program, we are still helping to process the recycling that is generated by the Chirripó National Park. Cloudbridge has a very longstanding collaborative relationship with the community association in charge of recycling.

My name is Marvin Andreas Biedermann. I’m a undergraduate student here at Cloudbridge doing research for my thesis. I’m studying the effects of human abundance on the frequency of species in Cloudbridge. I’m really interested in seeing how we directly affect the presence of animals on trails, whether it differs with species. Since I’ve been here I’ve developed a whole new array of skills ranging from camera trap knowledge to animal identification. I’m happy to be here and hopefully learn some new things and teach others about wildlife conservation.

Earth Day is an important day, and here at Cloudbridge we try to celebrate our beloved home not only on April 22, but every day! This year we decided to celebrate this special date in house, with a tree tour with Edgar in the primary forest, a climate change discussion, a presentation about the International Dark Sky Association (which we are joining as a Dark Sky Reserve!), and a lovely potluck dinner. Since the clouds didn´t really let us enjoy the meteor shower that was visible on this date, we still enjoyed some outdoor evening time, dancing with fire poi!

CONUBI, which stands for Conociendo Nuestra Biodiversidad (Knowing Our Biodiversity) is an environmental education program jointly developed by various environmental organizations of the area, with the support of the UNDPs “Productive Landscapes” project. Since the program has been virtual due to Covid-19 restrictions, 5 participants were randomly selected to attend a CONUBI weekend at Cloudbridge with a parent, following all Covid-19 protocols. The activity was a huge success! Thank you Tom and Linda, for letting us use your marvelous front porch as our activity base : )

Hi, my name is Harold van Riessen. I’m a student of International Forest and Nature Management at Van Hall Larenstein University of Applied Sciences in The Netherlands and I am specializing in Tropical Forestry. I am here at Cloudbridge for 2 months to write my final thesis and I am doing a research on bird diversity between different forest succession stages. The Cloudbridge reserve has an extremely high bird diversity so sometimes it’s a real challenge for me to identify all the different species. But it’s a lot of fun to go out early in the morning and look for birds and field assistants help me to spot them. This is also a nice opportunity to meet new people and make friends!

Eddo (right), looks at a bird that Harold is pointing out.

Hola, my name is Eddo, from the Netherlands. Volunteering at Cloudbridge has been such a wonderful, inspiring and above all very educational experience! Last year I graduated in environmental sciences, where I learned a lot about the physical processes that are governing our Earth. However, I felt like I was missing practical/field knowledge during my studies. Being here at Cloudbridge has helped me fill this knowledge gap by being so close to research and being involved in a reserve which has done so much in conservation. It has been a blast to wake up every morning to hike into the cloudforest to observe birds, calculate the biomass of lianes or help with any other project. This together with being surrounded by astonishing nature and lovely people makes this place especially exhilarating.

Jeff and Sylvie: We retired a little early from careers in project management and teaching in order to volunteer for charities around the world and to give something back for the lucky lives we have had. We have been nomadic for the last three years, volunteering for NGOs in Ethiopia, India, Italy and Costa Rica, generally in the areas of poverty alleviation, education, women’s empowerment and the protection of ecosystems. We adore learning new skills in one part of the world and training others in them in another. We also love all things cultural – history, heritage, music, reading, films, food, etc. We are writing about our adventures on our blog which includes so many beautiful memories for us to look back upon. 

Hello! My name is Madyson and I am visiting Cloudbridge from Canada. I work for Global Vision International (GVI) and supervise 5 volunteers here at Cloudbridge. I have an Undergraduate degree in Environmental Studies and a Masters degree in Tourism – responsible travel is my passion! I have been living here for 5 weeks and have loved every minute. We have seen frogs, countless birds including multiple Resplendent Quetzals, spider monkeys and peccaries too. It’s been an incredible experience living in the jungle with an amazing group of dedicated volunteers and researchers from around the globe.

My name is Jann Erik Simon, I’m 23 years old and I’m from Germany.
I am volunteering in Cloudbridge for around five weeks because I love nature but my knowledge about it is very little, so I decided to search for an opportunity where I can learn from researchers and at the same time I can enjoy the nice and beautiful environment of tropical cloudforest. Cloudbridge connects both very well.
Also it’s nice to live together with other people who have similar interests in terms of nature conversation.
Cloudbridge is already my third station in Costa Rica to volunteer. Before I worked with the indigenous Bribri in the organization El Puente in Puerto Viejo and in Alajuela in the Fundación Manos Abiertas with handicap people.
Besides nature I’m a passionate football player and I like to do workouts. Also I like to explore the world, I really like remote places with people who know how to live with nature without destroying it and to live a happy life which is not based on consuming.
Back in Europe I will study International Development Management in the Netherlands and after that I want to head back to Costa Rica to search work for an NGO.

Hey everyone! My name is Patrícia, I am 21 and I am Portuguese. For the last 3 years I have been studying Animal Behaviour in England, which has been a crazy ride. For my placement year, I came to Cloudbrige to conduct a research on white-nosed coatis’ habitat preference and it has been an amazing experience. Being able to learn, discover nature and share this with all these people has been a blessing.

We are thankful for the many research interns and volunteers who have joined us over the last couple of months, enabling us to conduct more surveys and other research tasks on the reserve. The camaraderie of our lovely group has been great!

Researchers and volunteers enjoy a night tour.

This month we have acted on the advice of one of our herping interns and dug out a boggy area in the reserve to make a shallow pond, thus providing better habitat for frogs. Many frog species lay eggs in bodies of water of this sort, and we are excited to see how it will be used over the coming months!

UNED student Gabriel Zuñiga shares with some of our interns information about his pollinator research here at the reserve.

We are pleased to be able to continue collaborating with the San Gerardo recycling project!

Another exciting development from this month is that we have now officially applied to the International Dark Sky Association, as we have beautiful dark skies free of light pollution here at the Reserve. Our first related activity will take place this coming Earth Day, April 22nd, with star-gazing and other activitis. This day there will also be a meteor shower.

A very important value here is companionship since we share with some other boys and girls from other countries…

Hello. I am Karol. I am 20 years old. I am student of tourism guide in the INA los Santos, but I am doing my práctice at Cloudbridge reserve. I live in the zona de los Santos. Cloudbridge is a beautiful place, it is one of my best experiences. I have learned a lot about birds, a camera trap project, something very interesting and about trees, which are my favorite natural resource. You can learn close to other cultures since you share with other girls and boys from different countries and it is something very charming and motivating.

Hello my name is Hellen Romero Calderón. I live in the “zona de los santos”. I am a tourism student and I am 20 years old. But at the moment I am in Cloudbridge where I have learned about new cultures since we share with people from different countries. Where you learn to work as a team at all times. Cloudbridge is a place where you do not stop learning new things where each tour is full of happiness. Cloudbridge is a place full of life, full of color from a small insect to a huge tree without leaving behind the beautiful hummingbirds and the restless monkeys. For me, Cloudbridge is the best experience I have had so far.

This male Resplendent Quetzal was seen on the Montaña Trail.

Quetzal season is here!  We have been lucky enough to view multiple pairs over the last month, including near the nesting boxes that we have placed around the reserve.  Over the last three years we have placed nesting boxes in strategic locations throughout the reserve, and though pairs have come to inspect them and spend time cleaning them out, we have yet to observe a full nesting in these boxes. 

Our female Quetzal, Margarita, inspects the nest box near Tom and Linda´s home.
Her partner, Chico, also has to check it out,
Here they are together, what a lovely couple! Photo credit: Haydn West.
The Trogon family has not only the Resplendent Quetzal, but also other lovely birds such as this Collared trogon, who can also be seen around the reserve.
Los Crestones, one of the emblems of Chirripó National Park and the Talamanca mountain range.

This month we have begun collaborations with the National Park Service and another researcher to support their camera trap monitoring programs within Chirripó National Park. This exciting development also led to our being able to participate in a bird monitoring activity put together by the National Park Service on February 27th. Our brigade surveyed bird point counts between kilometers 10 and 11 on the main trail up to Chirripó. Because we spent the previous night in the lodge at the base of Los Crestones, we were also able to enjoy a spectacular sunset from a lookout on the way to Sabana de los Leones.

We hope that this New Year of 2021 will bring many blessings, health and happiness to all! On a global scale, we trust that this year we will be able to put the Covid-19 pandemic behind us, in addition to taking aggressive action on the climate crisis.

Mt. Urán is very clearly visible during the dry season.

In this part of Costa Rica, it is now the dry season, or “summer” as we like to call it, and we have been enjoying the ability to hike all day without worrying about the rain showers that can usually be expected in the afternoon during other parts of the year. So this is a lovely time of year to visit the Reserve, for those of you who have the opportunity. We also have availability in our rental cabins, so come and enjoy the cool mountain air!

We are very excited to announce that two researchers from early 2019, Charlotte Smith and Harry Elliott have just gotten their paper published! They observed hummingbirds feeding on fruits which is an almost undocumented behaviour for hummingbirds and the first ever documented for these species. They submitted their manuscript back in the summer of 2019 and after a number of hiccups it’s finally been published in Ornitología Neotropical. Here’s the link:

This month is also a special time because the Resplendent Quetzal is around once more. Though this picture is not the best (it was taken from a cell phone), it was taken right near the entrance to the reserve, when this handsome bird and his mate were present early one recent morning.

We are constantly improving the facilities of Cloudbridge Nature Reserve, now with the addition of picnic tables and additional benches located at scenic locations throughout the Reserve. Please feel free to come and enjoy a lovely picnic lunch with your family here at Cloudbridge, just remember to take all of your trash, including leftovers! Leaving food waste in the Reserve can be detrimental to wildlife, so it is important that you not leave organic waste to “compost” in the reserve.

Though San Gerardo´s recycling program has been temporarily suspended due to the Covid-19 pandemic, visitors to Chirripó and other select areas have continued generating recycling, whih still needs to be sorted and compressed. Cloudbridge has a long-standing cooperative relationship with this program, and it was a pleasure to join don Omar Garita in this task recently. Thank you don Omar, and our team, for your efforts!

Staff, Researchers and Volunteers

It is so lovely to have a nice team!

Hello, my name is Paula Pebsworth and I am from San Antonio, Texas. I am honored to be the new Scientific Coordinator here at Cloudbridge. I have a doctorate in Primatology from Kyoto University’s Primate Research Institute. My areas of expertise are self-medicative behavior (how animals maintain their health) and human-wildlife conflict resolution. I have come to Cloudbridge to help others with their research and to coordinate projects that will facilitate our understanding of the fauna and flora that make their home at Cloudbridge. My time at the reserve will be spent coordinating the reserve’s scientific activities. I will also be training and supervising researchers and interns. I will also provide logistical support for independent researchers and oversee and coordinate collaborative projects with other organizations. Additionally, I will be conducting my own research. I look forward to providing researchers, interns, and volunteers with wonderful experiences while living in this beautiful cloud forest among like-minded people. I look forward to making new friends, improving my Spanish, learning to identify neotropical plants and animals, and enjoying the night sky here at Cloudbridge.

Hello! My name is Laura Picado Abarca, I am from Costa Rica and I studied Industrial Chemistry. Right now I am a chemistry teacher and I came to Cloudbridge for two weeks to help with the projects they have and also to improve my English.
During this time I participated in the project with camera traps and also collaborated with the owl survey and making a fungi booklet. During the tours I took some photos of the incredible species of animals and plants that can be found. I have had a great experience, I met incredible people and I hope to return at some point

My name is Nina, I am from Stockholm, Sweden, where I live and study a bachelor in biology . I came to cloudbridge for one month to gain some over all field experience in conservation and different survey techniques. I absolutely love it here, being surrounded by stunning nature and enthusiastic people is such an inspiration.

  • Just in case you did not click on the link to the hummingbird study above, we highly recommend you check it out! It is always exciting when our research interns are able to publish their results : )
  • We have been aware of the severity of the global decline of insect populations for some time, but this article just helps to hammer the point home.
  • When most people think about commodities markets, assets like gold, wheat, or cattle come to mind. But there is a growing list of environmental commodities traded on exchanges too. These commodities include things like carbon offsets and white certificates. You can learn more in this guide.
  • Designing our built environment to promote human health and wellbeing and resilience to climate change is one of the best strategies that we have as society for facing this crisis. The Global Landscape Forum has recently published a series of Policy Recommendations, we invite you to check it out.
  • Many times when large infrastructure projects are developed, little thought is put into what will happen once the infrastructure´s life span has ended. This is how we are now in a situation where over half of the world´s population will soon be living downstream from obsolete dams, a worrisome prospect.
  • The UNEP has warned that most countries are not taking enough action to adapt to climate change, warning that financing climate change adaptation measures should be a global priority. This video reinforces the importance of planning, financing and implementing adaptation measures.
  • In this month, more than 50 countries have pledged to protect biodiversity as part of the High Ambition Coalition for People and Earth.
  • And to end on a positive note, we would like to congratulate the Biden administration for the swift and concrete steps that have been taken to address the climate crisis and promote environmental justice. We are also pleased with the nomination of Representative Deb Haaland as interior secretary of the USA.

Happy holidays! From all of us here at Cloudbridge, we hope you have been able to enjoy your holiday season in the company of your loved ones. 

Here on the Reserve, we are very thankful for all of the visitors who have been coming to the reserve, and for the company of our “bubble” of staff, interns and volunteers here on the Reserve.  In this way, we were able to enjoy a special Christmas dinner and games.

The December Cloudbridge “bubble” made up of staff, volunteers and researchers enjoyed a lovely Christmas dinner together : )

We are pleased to be making Cloudbridge a more accommodating place for visitors, with the addition of some picnic tables and benches within the reserve, providing a space for families to enjoy time together in nature while visiting the reserve. Come with your loved ones to share some spectacular hiking and a picnic lunch in the cloud forest. We were also able to reconstruct the bridge which connects Cloudbridge North with the rest of the reserve, so it is now possible to visit Catarata Don Victor once again!


Hello, my name is Sebastian Brehm, I’m 18 years old and I come from Schweinfurt, Germany. After I finished high school this summer I wanted to travel Central America and learn about new cultures. I see myself as an adventurous person so volunteering in the Nature Reserve Cloudbridge was the perfect fit for me. During the 4 weeks that I was here I have experienced the unique environment with the mountains, the animals and the rainforest. Therefore if anyone asks me about the must go places in Costa Rica, I would definitely suggest the Nature Reserve Cloudbridge. Pura Vida!

Jessica Bardey´s partner Christian enjoyed this holiday season here at Cloudbridge.

  • Many of you may have heard earlier in December how UN Secretary General Antonio Guterres has characterized humanity as “waging a suicidal war against nature”. This article gives voice to some of the youth who have been part of the UN´s advisory board on important environmental issues.
  • As has become increasingly apparent, climate change is a major issue of our time. Of all the ramifications linked to this major issue, human migration is one of the consequences that we as society can choose to respond with empathy and compassion, or with callousness and closed arms.
  • An article recently published in Nature magazine has found that human-made materials now significantly outweigh Earth´s entire biomass.
  • Approaching climate change from a geopolitical perspective, it is important to note that some regions may experience benefits from a warming world, while many others will of course suffer devastating negative impacts. This article explores how “Russia could dominate a warming world.”
  • As always, we try to end on a more positive note, because unfortunately much of this suggested reading could be quite upsetting. In this beautiful essay, Terry Tempest Williams explores the idea of Unraveling, and ponders how we can reweave the world anew, “not from the places of fear and doubt, but from the intimate spaces of belonging?”

November 2020

All in all November has been a good month for Cloudbridge Nature Reserve. Though we got off to a wet start, thanks to Hurricane Eta, we are very thankful to have not suffered any severe effects from this storm. In the United States, November is the month of Thanksgiving. Though this holiday should be examined critically for its misrepresentation of the relationship between colonizers and those who were already living on the American continent, the concept of giving thanks is extremely important and should take place every day of the year. Here at Cloudbridge, we give thanks for the opportunity to steward this land that is home to so much biodiversity; thanks for our health, facilitated by a healthy environment; thanks for the founders of the reserve and all who have supported it for almost two decades. Thank you!

Catarata Pacífica was quite full after Hurricane Eta!

This month started off with Costa Rica suffering the indirect effects of Hurricane Eta, with over 72 hours of non-stop rainfall and some flooding, landslides and other damage.  Here at Cloudbridge we suffered minimal damage, with the river taking out two of our bridges that access Cloudbridge North and some very minor slides.  However, our hearts go out to the relatives of those who lost their lives and the thousands of displaced families in Honduras, Nicaragua and Guatemala.  2020 has been a record-breaking Atlantic hurricane season with a total of 30 named storms, and the first year there has ever been two major hurricanes recorded in November.  Central American countries were devastated by Hurricanes Eta and Iota this November, affecting an estimated 5.2 million people in this region.

This image is from a town relatively close to Cloudbridge, where the effects of Hurricane Eta were felt a bit more keenly…

Of course we cannot talk about this hurricane season and the devastation it brought to the Central American region, without mentioning climate change. Warmer ocean temperatures lead to more evaporation, setting the stage for wetter and stronger hurricanes. This year was the fifth consecutive above average Atlantic hurricane season from 2016 onward, and a general trend is that the season has been beginning earlier, and ending later. This month also saw devastation from extreme weather events in other parts of the world, especially from Typhoon Vamco, which caused devastation in the Phillipines and Vietnam.

For the past 10 years, Cloudbridge has enjoyed a unique and rewarding partnership with the Carol Martin Gatton Academy of Mathematics and Science in Kentucky. On November 6th, it was announced that this collaboration has received the Innovative Partnership Award from the National Consortium of Secondary STEM Schools (NCSSS). The NCSSS includes member high schools, many ranked as the best in the country, along with affiliate members (colleges, universities, summer programs, foundations, and corporations), that share the goals of transforming mathematics, science, and technology education. The NCSSS Innovative Partnership Award recognizes inventiveness in partnerships between member schools and partner organizations. To receive the award, the partnership must support and advance goals of both organizations, strengthen STEM in the partners’ communities, and provide a replicable model that can be implemented at other member schools. Over the last 10 years, 224 students have enjoyed a unique and memorable learning opportunity at Cloudbridge Nature Reserve.

Volunteers and Interns

My name is Jessica Bardey and I am studying International Nature Conservation as my Master‘s degree at the Georg-August-University in Göttingen, Germany. As an internship in a nature conservation project is part of my studies, I came here to Cloudbridge and so far it has been amazing. Cloudbridge offers a unique environment to explore and you can learn so much about tropical forest ecosystems here. I am an intern in the camera trap monitoring project and it’s fascinating to see the variety of animals which appear on the photos. In total I will be staying for twelve weeks, and it already feels as if that is too short to see all the amazing things offered by this beautiful spot in nature. Another part of my studies will be a semester abroad in New Zealand, which I am also looking forward to quite a lot. It is so exciting to be able to see the world and learn more about conservation and how it is done in other countries!

¡Hola! My name is Valeria González, I am a student of International Commerce. I envision a more fair, harmonious and solidary commerce, my greatest dream is to help people, small producers and others with what I have learned. Over the years, I have found a great love for Yoga, which has guided me on a path of understanding and love for all of existence, and has allowed me to follow my heart´s path at all times, which is why I am now serving here at Cloudbridge. I love being in direct contact with nature, and to fully appreciate nature. To be able to breathe pure air, smell each flower, feel the water, watch birds fly, see the beauty in each part of Mother Nature is a joy that leads me to understand that we are part of the forces of nature, of each plant, tree, animal, river, the Sun and the Moon, we are part of it all. I fully believe in the philosophy of “Buen Vivir”, of living fully and with complete harmony between the individual and the collective, with balance between humans and nature, for a development with more awareness and well-being. I am grateful to continue weaving my life in this marvelous place, where I will serve each instant with all of my love. Thank you Cloudbridge for allowing me to be here.

“I dreamed that life was joy; I awoke and saw that life was service; I served and saw that service was joy”

Hello, my name is Isabella Marshall, I am from the United Kingdom. I am very excited to start the new position as Base Coordinator here at Cloudbridge. I have a degree in Biology and a Research Masters in Environmental Science and Ecology. I have come to Cloudbridge to experience living amongst the amazing cloudforest, and to learn about the wonderful fauna and flora that live within it. My time at the reserve will be spent supporting the volunteers and interns with their studies, and assisting the staff team with running the reserve. I hope to make many new friends and learn many new skills here at Cloudbridge, Pura Vida!

Born in the province of Alajuela in Costa Rica, Mayi is a yoga instructor, holistic therapist and math teacher whose greatest vocation is to be of service. Lover of being surrounded by nature and admiring the sublime existence through it, he enjoys meditating and listening to the sounds of the environment, working with wood in the workshop, hiking through the different trails of the reserve and welcoming all our visitors. His vision is: “may the good practices and thoughts from the light that we evoke enter us and guide us in the right direction”. Feel free to ask him anything during the time you are with us.

Hello, everyone! My name is William, I’m 19 years old and I come from Leipzig, Germany. I would describe myself as an ambitious, sensible person, but also as a team-ready person. I just finished high school and now I want to travel around the world for a year. This trip should start in Costa Rica. I’ve been volunteering in cloudbridge for a month now and I couldn’t have chosen anything better! Because I fell in love with the reserve here in the middle of the rainforest and find it wonderful! So, if you have the chance, make a tour to the cloudbridge nature Reserve, you won’t regret it! See you soon and Pura vida!

Around the Reserve

Once again, our director and her family have participated in a course on identifying fauna of Costa Rica. Here are some of the 7 species of bats that were trapped in the nets! They were promptly released, of course. We are looking forward to having the instructor come up to Cloudbridge soon!
