Active Nest Buffers Clause Samples
Active Nest Buffers. Active nest sites and protective buffer zones shall be designated as environmentally sensitive areas(ESAs), where no Project-related activities or personnel may enter. These designated areas shall be protected during Project activities with the establishment of a fence barrier or flagging surrounding the nest site. The Qualified Biologist shall determine the necessary buffer, in consultation with CDFW, to protect nesting birds based on existing site conditions, such as construction activity and line of sight, and shall increase buffers if needed to provide sufficient protection of nesting birds and their natural behaviors. Buffers shall be approved in writing by CDFW prior to the continuation of Project activities.
Active Nest Buffers. Active nest sites shall be designated as “Ecologically Sensitive Areas” (ESA) and protected (while occupied) during project activities with the establishment of a fence barrier surrounding the nest site. The typical minimum distances of the protective buffers surrounding each identified ESA are the following: i) 1,000 feet for large raptors such as buteos; ii) 500 feet for small raptors such as accipiters; iii) 250 feet for passerines. A biological monitor or qualified biologist shall monitor the behavior of the birds (adults and young, when present) at the nest site to ensure that they are not disturbed by project-related activities. Nest monitoring shall continue during project-related construction work until the young have fully fledged, are no longer being fed by the parents and have left the nest site, as determined by a biological monitor.
