Site(s) Implementation Monitoring Monitoring and Reporting Monitoring Verification of Mitigation Measures Affected Procedures Responsibility Action Schedule Compliance • The qualified biologist shall be present during tree and structure removal if potential bat roosting habitat or active bat roosts are present.Trees and structures with active roosts shall be removed only when no rain is occurring or is forecast to occur for 3 days and when daytime temperatures are at least 50°F. • Removal of trees with potential bat roosting habitat or active bat roost sites shall follow a two-step removal process: 1. On the first day of tree removal and under supervision of the qualified biologist,branches and limbs not containing cavities or fissures in which bats could roost,shall be cut only using chainsaws. 2. On the following day and under the supervision of the qualified biologist,the remainder of the tree may be removed,either using chainsaws or other equipment(e.g.excavator or backhoe). 4.E-1.Biological Resources(cont.) Removal of structures containing or suspected to contain potential bat roosting habitat or active bat roosts shall be dismantled under the supervision of the qualified biologist in the evening and after bats have emerged from the roost to forage.Structures shall be partially dismantled to significantly change the roost conditions,causing bats to abandon and not return to the roost.
