Canopy Fogging

During the past few years I have seen many Chilean Forest destroyed by industrialization. With the hope of measuring and mitigating some of this destruction I started a project to quantify biodiversity through Arthropod Monitoring. Thanks to a gift from Dr. Richard M. Bohart Emeritus Professor I started the study of the canopies using the fogging methodology.

Richard M. Bohart works on the Systematics of Hymenoptera. His scientific research focus on Sphecid wasps. Today he contributes in sorting material for the Essig Museum of Entomology. Chilean temperate forest contains and amazing number of creatures that are far to be known. Research tends to focus in those charismatic places like rain forest leaving outside those temperate areas like Southern South America, South Africa, New Caledonia, Australia and New Zealand may possess a significant number of unique taxa requiring urgent attention.

Terry Cuneo (Davis) was doing the data base for this field trip.

We started at the Chillán Cordillera, with several Nothofagus spp.

Sergio Ocares parataxonomit and Cristian Muñoz (Utal) help collecting and sorting the specimens.

Patricio Caroca (ChileFog) came to the first 2 expeditions to conduct the fogging.

I positioned 40 trays of 1 m diameter under a selected tree. I used Golden Eagle with a pirethroid. I recollect the specimens after a 2 hrs dropping time in Whirl-Pak bags in 90%OH. Each sample contains data with GPS, host, and place.
