Rainforest XPRIZE: Community Biodiversity Data Collection (2021-2022)


Untouched (primary) tropical rainforests are among the largest repositories of forest biodiversity in the world. Unfortunately, they are being degraded and destroyed at a rapid rate, and many ecosystems are being lost forever. If researchers can document the biodiversity of the rainforests before they are destroyed, the world will at least stand a chance of recovering them in the future and perhaps the information gained will raise awareness and support for policy that prevents deforestation.

The process of documenting the biodiversity of rainforests is difficult. Much of it resides in the canopy hundreds of feet above ground, which is the region most devastated by deforestation and most poorly replaced by unaided regrowth. The canopy is very hard to access using conventional scientific tools. Satellite imagery cannot penetrate into the canopy due to the dense vegetation, and the resolution is not adequate to detect small plants and animals or to identify trees accurately. Human canopy climbing is time consuming and dangerous, but arboreal canopy camera traps are able to detect many more species than ground-based cameras alone. This indicates that a technology to rapidly collect data from the rainforests’ upper layers would greatly increase the ability to perform rapid biodiversity surveys.

Project Description

A Duke team has been participating in the Rainforest XPRIZE competition by developing technology to engage a broad community in identifying rainforest canopy species quickly and accurately. This project will set up a trial of the technology in an actual tropical rainforest through an iNaturalist community event. The project also aims to make the biodiversity of tropical rainforests the focus of a broad community of iNaturalist users by making the normally inaccessible rainforest canopy transparent in real time. 

Team members will help develop large heavy-lift drones that can fly deep into previously impenetrable rainforest and drop remotely piloted forest “diving” imaging and sensor drones to collect images, sounds and samples from the overstory, canopy and understory layers.

The team will work with iNaturalist to set up an event for Summer 2022 in which volunteer and expert biologists will identify a large number of tropical rainforest species using images from the forest diving drones. A documentary subteam will tell the story of the year-long planning and execution process.

Project components will include working on the iNaturalist event and community development; generating drivers for the technology development; developing the rainforest data collection systems; working on the data processing for identification; and telling the story of the project and building the community through engagement.
