Name: Goshawk - Threshold Zone

Display Field: Nest

Type: Feature Layer

Geometry Type: esriGeometryPolygon

Description: This feature class contains goshawk threshold zones based on the TRPA definition of 500 acres (± 5 acres) of the best habitat surrounding a nest, including a ¼ mile radius around the nest tree. Threshold zones were delineated without regard to land owner or known project areas. The LTBMU goshawk habitat model and the author’s personal knowledge of each site were used to delineate habitat since time and funds for field visits were unavailable. Outside of the ¼ mile buffer high quality habitat was prioritized, followed by moderate quality habitat. Low quality habitat was excluded where possible. Where ¼ mile nest buffers overlapped, one threshold zone that included all ¼ mile buffers was made, equaling 500 acres, regardless of the number of nests. The one exception to this is the Hellhole territory. The combined overlapping ¼ mile buffers alone equaled more than 500 acres. In this case the threshold zone exceeds 500 acres and does not include habitat beyond the nest buffer. Only nests where the tree has been verified to be non-extant (Cascade Lake 1984B, and Angora Creek 1981B, 1981D, 1991C, 1992A, 1993C, 2001A, 2003A and 2004I) or where the nest tree is outside the TRPA boundary (not always the same as the LTBMU boundary) (Genoa Peak 1999D, 2003L and 2004L, and Martis Peak 2009F) were excluded from this shapefile.
