Wildland Studies

Pacific Biodiversity Institute has been studying and mapping wildlands since 1993. These reports are in PDF format.

We provide these reports to you without charge. However, please donate to our non-profit organization so that we can continue doing this work and providing this service.

These reports are based on field studies, GIS analysis and remote sensing applications. The objectives of the studies were to locate and map roadless areas and wildlands. We also analyzed the wild areas for their conservation potential and biodiversity attributes.
