In 2015, the Biodiversity Institute of Ontario and the rare Charitable Research Reserve partnered to inventory species present on the rare property in Cambridge, Ontario, Canada. Inventory efforts were largely passive, using malaise and pitfall traps to target mainly Arthropoda specimens over a period of four months (May to August 2015). In addition, on August 16, 2015, international and local experts joined together for a BioBlitz in the research reserve to document taxa from a variety of major groups including invertebrates, vertebrates, plants, fungi and lichens. The resulting specimen and observation records are released to the public here.
