Whether we perceive it or not, the forest is alive; there is movement, there is disorder, and—most importantly—there are endless interactions. This last word is the key to help make this hidden world clear to our human “worlds,” which are so short and tiny in comparison to the existence of these forests.
When you walk through the old growth and secondary forests of the Osa Verde BioStation (Piro), you can see everythimg from herbs, seedlings and shrubs to gigantic trees hundreds of years old. Commonly seen are a great diversity of birds and insects, and sometimes one can have the good fortune to observe peccaries or to spot a small wild cat.
Now, there are many other things that we cannot witness, either because they occur at scales unimaginable to the human being (at a microscopic level, like bacteria, or in the heights of treetops) or because it would take months or years to notice the patterns of a certain event. One way to notice these small scale changes that happen in the forest is through observing the difference between day and night. In the night, more sounds are heard, even different events or movements are observed.
Observing a higuerón seems impressive to us all, but the interactions are what fascinate biologists: the complexity of their pollination related to certain wasp species, the presence of hemiepiphytes (a plant that stays in another) that present the majority of fig trees (Ficusspp) and how they affect the development and biology of other plant species. In addition, there is a large number of birds that feed on the fruits of Ficus and are also their dispersers. The Fig tree is related to an endless number of animals and events. This is considering only a specific tree; therefore, the amount of interactions in the forest is unimaginable, more taking into account that over time new relationships will appear.
The sad thing about all this is that as you learn more about the complexity of a forest and the interdependence among all its components, when you hear that people are cutting down a forest, extracting endangered species, polluting of rivers, hunting and causing many other environmental problems, you realize that the impact is at the ecosystem level and that recovering the conditions of a forest with all its interactions will take years or even centuries.
When a person for personal and economic interests cuts down a tree that is hundreds of years old and says “there are many other trees” or even plants a new one, perhaps he or she does not know or does not share the great feeling of entering the cave formed at the base of a great old garlic tree (Caryocar costarricense), of feel part of nature itself. More importantly, perhaps he or she does not see the amount of bats that depend on said cave, the facilitation in the dispersal of seeds, the great source of food for so many animals and all the storage of carbon during decades that helps us to be here today delighting in all these interactions.
That’s why I want to be part of those interactions in a positive way, through inducing positive change. As the change from being a Osa Conservation Restoration & Rewilding Field Course student to being the Coordinator of the Healthy Rivers program here, I hope that this challenge helps to conserve many interactions in the veins of our planet.
