Long-term research project with Utrecht University

Long-term research project with Utrecht University

Stichting Adopteer Regenwoud’s research project is entering an exciting new phase thanks to a long-term collaboration with Utrecht University. The foundation was ready for a new step to professionalize the research project and Utrecht University was looking for a stable and reliable partner in Central America to conduct solid research in the rainforest. So for both parties this is a wonderful collaboration! Because of this we will make a big step in professionalizing our current research on biodiversity in our reserve. Together with the visiting students we will focus on scientific research in which the diversity and development of nature in our reserve, with an emphasis on flora, is central.

From fauna to flora

In recent years, we have been able to host and supervise hundreds of students and volunteers from different educational levels and institutes. This mix of MBO, HBO and WO interns provides a varied learning environment for all participants and will continue to be a core value of our research project. Together we have learned a lot about the biodiversity in our reserve, observed rare and endangered species and even found undescribed species. In doing so, we have been especially looking for animals because they are relatively easy to name. Now we will work on plant diversity, and PhD students, professors and others specialists will also contribute to the knowledge of our reserve.

Influence of land use

The background of the study has everything to do with the genesis of our beautiful reserve. Man has had a great influence on nature in our project area for centuries. Deforestation, agriculture/livestock but also rainforest regeneration have created a mosaic of different habitats. So the rainforest we protect within the boundaries of the reserve is not all one and the same nature. For example, parts of the reserve used to serve as pasture or forestry plantation, while others have been covered by ancient forest for a very long time. Thanks to the studies we conducted in recent years, we know that the entire reserve fulfills an important function as a safe habitat for numerous (special) plant and animal species. With the new research, however, we are zooming in further and asking what past land use is currently affecting life in the various habitats.

Differences in tree species

Life in the rainforest obviously depends on the trees there in many ways, for example as a source of food, shelter, substrate for other plants and so on. Different tree species provide different services in this regard and make the presence of other plant and animal species possible or impossible. Moreover, tree species sequester carbon dioxide in different ways in trunks, branches and roots. Therefore, the number of trees and their species composition are a very important factor in rainforest biodiversity. We want to investigate whether there are differences between the habitats found in the reserve. Does rainforest that was pasture 40 years ago differ from rainforest where there was once a forestry plantation, for example. And how do they compare to an old, pristine rainforest?

Reservation in compartments

In the coming years we will divide the reserve into a large number of imaginary boxes. These boxes will be stored using GPS. Within these courses we will take measurements. In a first phase we will look at the thickness of the trees and their species composition in different courses. These data will tell us what influence land use decades later has on tree diversity and CO2 uptake. Moreover, by re-examining the courses annually, we will see how the forest continues to develop there. In addition, we can combine the knowledge we have gained about the animals with the knowledge of trees to reveal new relationships. In a later phase, we will also start surveying the rest of the vegetation (herbs, mosses, bromeliads, orchids, etc.) in these courses to get an even more complete picture. Research projects done on this scale and precision are scarce and of great value worldwide.

Input from researchers at Utrecht University

This ambitious research plan is only possible with the professional input of researchers from Utrecht University and from other institutes. However, the help of our students and volunteers remains indispensable. The knowledge we will gain will help Foundation Adopt Rainforest to understand the value of the reserve even better and possibly make more targeted choices for future rainforest acquisition or land use recommendations in the region. In addition, our data will serve a much broader purpose in the longer term, as regeneration and reforestation are of great importance globally in the fight against climate change, habitat fragmentation, and species and biodiversity conservation. Our project can serve as a show-case in the future and data can be extrapolated to large bids in the tropics so that conservationists can take effective action.

We can’t wait to get started with our students and volunteers on this monster job, which will take several years to complete, and hope that (potential) visitors are equally excited about the new research skills you can gain here. In addition, we remain active with ongoing research on tropical animals, so there is something for everyone.

The three-fingered sloth: the facts you didn’t know about this impressive mammal

What’s with the fur? Why do sloths sleep so much? This month, the three-fingered sloth is the animal of the month at Adopt Rainforest. And what’s more fun than hearing from one of the founders of Adopt Rainforest some fun facts that you won’t find in a standard biology book. Maarten van der Beek is one of the biologists at Adopt Rainforest and lives on the Work With Nature reserve in Costa Rica. (more…)

The rainy season part 1: Glass frogs

In the Caribbean lowlands of Costa Rica most rain falls in May to August. The fact that it rains is good for all life of course, but can be quite difficult for our biologists in the Work with Nature reserve; the paths become muddy, the laundry doesn’t dry and the project is sometimes briefly inaccessible because rivers are filling up.

Morpho butterfly in Costa Rica

This beautiful blue butterfly, measuring up to 15-20 cm, seems to appear and disappear with every flick of its wings. In fact, its underside is a clever trick of Mother Nature. On the underside, it is inconspicuous reddish-brown, with eyes to deter attackers. The bright iridescent blue, in turn, is to deter competition and attract females.


How to support a good cause!

Supporting a good cause. How do you do that? There are so many charities that it is difficult to choose. To which charity do you donate money? Which charity is reliable? And where do you actually start supporting a charity? The choice is vast in the jungle of charities. If you want to support a charity, it is important that the charity suits you. Choose an organization that does things you find important. This will make donating to charity a lot easier for you. With the tips below, you can be sure that you will soon be supporting a charity in a conscious manner. (more…)

Butterflies in Costa Rica

When a butterfly flies by, most people do stop for a moment to follow it with their eyes. They often have beautiful colors and the large soft wings compared to the small body make them look almost cuddly. In Costa Rica there are more than 1200 species of butterflies and of course we are very curious about the species that occur in the reservation of Adopt Rainforest.


Zoë on her wonderful experiences as a volunteer in Costa Rica

And then there you are, atop a hilltop, having a good cry. Or frantically trying not to let your fellow volunteer see how touched you are. My name is Zoë, I live near Hasselt in Belgium. I am an adult education teacher, and enthusiastic but very novice when it comes to nature. I would like to tell you about my wonderful experiences as a volunteer in the reserve of Adopt Rainforest.


CO2 storage in trees – how does it work?

CO2 storage trees – How does it work?

We all know how important trees and plants are for producing oxygen and absorbing CO2. Especially lately there has been a lot of news about the climate crisis, global warming, sea level rise, CO2 offsetting and the importance of preserving trees, plants and forests. In this blog you can read some background information on how trees store our CO2 emissions.


International Census of the Great Green Macaw

Critically endangered parrot species Yesterday the research program of Adopt Rainforest participated in the Censo Internacional de la Guacamaya Verde 2022. Or in English the International Sensus of the Great Green Macaw. Throughout its distribution, dozens of organisations participate in the next days to get an understanding of the current state of this parrot species. […]

The most special sighting in our reservation so far!

In recent years we have already seen many rare and unusual animals in our reserve such as the Northern Nacked-tailed Armadillo, Black-and-White Hawk-Eagle and several felines. However, what we recently encountered is many times more interesting to scientists. In 1989, Epigomphus houghtoni, the Limon Knobtail, a dragonfly species was described by Stephen Brooks based on […]

Special glass frog in the reserve!

Now that student Sonny, a pure night tour specialist, is about to finish his internship, a lot of great discoveries are made at the last minute. To top it all off, last week we found a special glass frog in the reserve. This Hyalinobatrachium dianae – Diane’s Bare-hearted Glass Frog was only discovered and described […]

Costa Rica‘s plant world is very extensive and varied. Over 12,000 different plant species (of which more than 1200 species of orchids!) are found. Climate, soil […]

Biodiversity in Costa Rica

Let’s start right away with a fun fact: Costa Rica covers only 0.3% of the Earth’s surface, but you will find almost 5% of the world’s flora and fauna species! Per area, Costa Rica has the highest biodiversity in the world!


The ceiba tree

The Ceiba tree, also called kapok tree, is an impressive sight with its trunk full of thorns and a growth rate of 2 to 4 meters per year. Those thorns allow the tree to protect itself from all kinds of animals. The tree is one of the forest giants of the tropical rainforest and grows […]

The Hummingbird

Most species are between 7.5 and 13 cm in size. You would almost think it is an out-sized bumblebee! Hummingbirds (Trochilidae) are the smallest birds in the world. They are a family of birds of the order swift-like. The family includes more than 300 species. Most species are found in South America. It is so much fun (more…)

Strawberry poison dart frog

By Zoë Schreurs

In Costa Rica, you can’t ignore them: the Oophaga pumilio. Pumilio means dwarf, and although they are barely 3 cm tall, it is hard to miss the poisonous strawberry frogs. In English, they are called Strawberry Poison Dart frogs because indigenous peoples used to use their poison to makepoison darts. They are also affectionately called the “blue jeans frog,” because they often look like red frogs in jeans. Although they are by no means all the same colors. There are some that are completely red or blue, rather yellow, green or orange, or with black stripes or dots. In total, there are some 15 to 30 color variations.
