Forest and Rangeland Ecosystem Science Center (FRESC)

Home

Scientists from the Forest and Rangeland Ecosystem Science Center capitalize on their diverse expertise to answer scientific questions shaped by the environments of the western United States. We collaborate with each other and with partners to provide rigorous, objective, and timely information and guidance for the management and conservation of biological systems in the West and worldwide.

Identification of bees in southwest Idaho—A guide for beginners

This document was prepared to help scientists and the public, both of whom may not be familiar with bee taxonomy, learn how to practically identify bees in sagebrush steppe and shrubland habitats in southwest Idaho. We provide information to identify bees to the level of family and genus. A tentative list of the bee genera captured at sites used...

Quantitative acoustic differentiation of cryptic species illustrated with King and Clapper rails

Reliable species identification is vital for survey and monitoring programs. Recently, the development of digital technology for recording and analyzing vocalizations has assisted in acoustic surveying for cryptic, rare, or elusive species. However, the quantitative tools that exist for species differentiation are still being refined. Using...

Insect communities in big sagebrush habitat are altered by wildfire and post‐fire restoration seeding

Natural resource managers sow grass, forb, and shrub seeds across millions of hectares of public lands in the western United States to restore sagebrush‐steppe ecosystems burned by wildfire. The effects of post‐fire vegetation treatments on insect communities in these ecosystems have not been investigated.We conducted the first investigation of...
