Either treatment will avoid occupied habitat or <br />treatment will be implemented in such a way that it does not disturb Alameda whipsnake. <br />If work occurs within occupied a qualified RPF or biologist be present on-site to monitor for <br />Alameda whipsnake, flag areas for avoidance and establish no-work buffers. Implementing <br />treatment activities within suitable Alameda whipsnake habitat would require focused <br />surveys to determine presence of Alameda whipsnake each day prior to work at each new <br />area. If crews are working within suitable Alameda whipsnake habitat, a qualified RPF or <br />biologist would conduct ongoing focused pre-treatment surveys during treatment <br />activities, adhering to methodologies recommended in Miller and Alvarez (2016). Within <br />highly suitable habitat, surveys would be repeated in treatment areas immediately prior to <br />vegetation removal to ensure that the species is not present prior to the start of work in <br />each scrub area. A qualified RPF or biologist would check suitable refugia within the work <br />area including vegetation and rock piles. When dense vegetation within suitable Alameda <br />whipsnake habitat inhibits visual survey effectiveness, the biologist would work closely <br />with the crew to intermittently cut a small amount of brush to allow surveys of small <br />areas. Active surveys would be performed throughout the vegetation removal activity <br />within suitable Alameda whipsnake habitat, and if work ceases more than one hour, the <br />area would be re-surveyed prior to restarting work. During this survey effort, the qualified <br />RPF or biologist would also advise the crew on avoidance of on-site potential refugia such <br />as burrows and rock piles. <br />Prior to vegetation clearing activities within suitable Alameda whipsnake habitat, <br />coverboards would be installed in key areas as determined by a RFP or qualified biologist. <br />The coverboards would be strategically placed to provide refuge for the Alameda <br />whipsnake leaving the work area. Coverboards would be inspected at the end of each <br />workday, and wildlife using them would be recorded.
