Report Background

Pacific Biodiversity Institute has been conducting studies of non-native, invasive species for many years.

These reports in PDF format were commissioned by various entities to help make informed land management and conservation decisions.


Report objectives

These reports are based on field studies, ecological and GIS analysis. The objectives of the studies include locating, mapping and documenting the presence of non-native, invasive species. Many of the reports include recommendations for invasive species management.
