If <br />potentially suitable roosting structures occur in Project areas, a qualified bat biologist <br />would conduct a Level 1 survey (year-round) for evidence of bat occupation, specifically <br />looking for signs of day-roosting such as fecal matter, staining, and carcasses. Based on <br />the results of Level 1 surveys, day and night emergence Level 2 surveys would be <br />performed (April 1 to September 15). If special-status bat roosts are detected during <br />focused surveys, a no-disturbance buffer of 250 feet would be established around active <br />pallid bat, Townsend’s big-eared bat, and other special-status bat roosts, and mechanical <br />treatments, manual treatments, and broadcast and pile burning would not occur within <br />this buffer. MM BIO-2b also states: “A qualified RPF, biologist, or biological technician will <br />be required to monitor the effectiveness of the no-disturbance buffer around the nest, den, <br />burrow, or other occurrence during treatment.” <br />Bats may be excluded from roost locations by a qualified bat biologist or under the direct <br />advisory of a qualified bat biologist from roosting structures in the work area only during <br />the periods from mid-February until mid-April (hibernation) and from late August until <br />mid-October (to avoid hibernation and maternity season). Bat elimination would follow <br />BMPs and must include the combination of two actions: 1) careful blockage of all openings <br />that are large enough to allow bats to enter and 2) installation of one-way valves placed <br />on the actively used openings to allow the bats to fly outside as they normally would but <br />not to re-enter. After 7–10 days, the one-way valves are removed, and the remaining <br />openings are blocked or sealed. Bat exclusion must be overseen by a qualified bat <br />biologist. <br />San Francisco Dusky-Footed Woodrat
