How do we inventory life in the canopy?


Inventorying life in the canopy of rainforests, like the Amazon, involves some unique and challenging techniques due to the complexity and richness of the environment. As explained by Paul Rosolie, about 50% of a rainforest's biodiversity resides in the canopy. To inventory this life, scientists and explorers use various methods:

  1. Climbing Trees: Similar to rock climbing, researchers scale trees to explore and catalog the life found high above the ground. This approach allows them to encounter a variety of species directly by navigating through the thick branches of the canopy, enabling close observations of flora and fauna like lizards, snakes, and numerous insect species 1.

  2. Canopy Platforms and Treehouses: These structures provide more stable access to canopy levels, allowing for prolonged study periods and observations of species that are rarely or never seen on the ground. This setup facilitates detailed studies on behavior, mating, and territorial calls among species like monkeys and birds that thrive at these heights 2.

  3. Innovative Methods: Some researchers have used creative solutions like hot air balloons equipped with nets to 'float' over the canopy. This method allows them to collect samples from the uppermost levels of the canopy without the need for climbing, providing access to species that might otherwise be unreachable 2.

These methods underscore the vast and largely unknown world within the canopy, revealing the importance of innovative techniques to understand and document the diverse life forms that inhabit these upper layers of the rainforest.

Paul shares his experience climbing trees, discovering new species, and the challenges of inventorying life in the canopy. They also discuss the taxonomical discussion of species on Earth.
