| Summary: | the incidental take of 1539 harbor seals (Phoca vitulina), by level B harassment only, at the Woodard Bay Natural Resource Conservation Area (WBNRCA), during the derelict creosote piling and structure removal project. Harbor seals were monitored by personnel from Cascadia Research Collective (CRC) based in Olympia, WA, at two different land based observation sites (north and south) within the WBNRCA. Monitoring was conducted on 14 days during the restoration work period (Table 1), which occurred from 1 Nov- 30 Dec 2010 (Table 2). The mean daily count for both sites was 52. Incidental Harassment Takes were recorded whenever seals entered the water due to construction activity. A total of 356 Incidental Harassment Takes were observed during the restoration project with a mean daily take of 25 and a corrected project total of 875 takes. Species of concern Harbor seals were the only marine mammal anticipated to be taken during the restoration project. The harbor seal is the most abundant marine mammal in the inland waters of Washington State. Based on population assessments conducted by Washington Department of Fish and Wildlife (WDFW) and National Marine Mammal Laboratory (NMML) from 1978-1999, the harbor seal |
