Canopy access
The study of the distribution of forest biodiversity is generally hindered by the difficulty of access to the treetop (canopy). The IBISCA research programme aims at studying the spatiotemporal distribution of arthropods in forests by relying on state-of-the-art canopy access techniques and devices including cranes, platforms (Solvin-Bretzel canopy raft), treehouses (IKOS) and balloons (Canopy-Bubble and Canopy-Glider). Professional tree-climbers are also of great help to collect the samples in the canopy.
SolVin-Bretzel canopy raft (Radeau des Cimes)
The SolVin-Bretzel is a 400m² inflatable platform which is put on the canopy surface. It was used during the IBISCA-Panama expedition.
Canopy Bubble (Bulle des Cimes)
The canopy bubble is a seat harness suspended from a helium balloon that moves along a rope laying over the canopy surface.

Tree-Climbers
Professional tree-climbers assist the researchers by collecting samples in the canopy.
