ERC’s staff is experienced in the full range of threatened and endangered species (TES) studies including Preble’s Meadow Jumping Mouse (Zapus hudsonius preblei), Ute Ladies’ Tresses Orchid (Spiranthes diluvialis Sheviak) and Boreal Toad (Bufo boreas boreas). Initially desktop evaluations are preformed on a property to define species of concern and known species population boundaries. ERC then conducts field reconnaissance as part of the presence/absence screening for individual species. Results of the field evaluation are presented to the U.S. Fish and Wildlife Service (USFWS) which often results in official clearance of a property. In the event that TES are present, ERC is experienced working with the USFWS and resolving issues in a timely, efficient manner.
