The Angora Fire burned approximately 3,100 acres in South Lake Tahoe, California in June and July 2007. The fire occurred in an area with high intermix of private and public land, adjacent to large expanses of undeveloped public land. The severity of the fire varied within the burned area, resulting in a mosaic of conditions. The primary post-fire actions have been to implement erosion control measures and to remove hazardous trees. The removal of snags and logs, even those that are highly scorched, is likely to reduce the ability of areas to support wildlife species dependent upon these features such as three species of Picoides woodpeckers.

Woodpeckers are considered keystone species, due in part to their important role as cavity excavators. Woodpeckers may have especially strong effects on ecosystem processes after fires, when cavity excavation, drilling, and bark peeling provide cover and foraging areas for other species. These activities may be limited or enhanced by fire severity and restoration treatments, with cascading impacts to secondary cavity users.

| 07/27/2017 5:38 PM | Kiara Cuerpo-Hadsall | Objectives: Woodpeckers excavate cavities in trees to use as nests for the brooding and rearing of their young. After fledging, these cavities are abandoned but remain in the environment for use by other species that are unable to excavate cavities but rely on them for reproduction and cover (secondary cavity users). When fire destroys cavities, secondary cavity users may be unable to breed in the burned area until woodpeckers colonize and create new cavities. Therefore, understanding how woodpeckers utilize burned areas is important as they provide a keystone function by creating habitat for other organisms. |

| 07/27/2017 5:37 PM | Kiara Cuerpo-Hadsall | Findings: • This research investigated nest site selection in three species of Picoides woodpeckers (P. arcticus, Black-backed Woodpecker; P. villosus, Hairy Woodpecker; and P. albolarvatus, White-headed Woodpecker). Using logistic regression, we determined the factors with the greatest influence on nest presence and found that they differed among the three species. • The density of small snags (by DBH) was positively associated with the presence of Black-backed Woodpecker nests. • Nest presence of White-headed Woodpeckers was positively associated with tree decay and negatively associated with tree height and density of small trees. *** See www.fs.fed.us/PSW/partnerships/tahoescience for additional findings. |

| 07/27/2017 5:36 PM | Kiara Cuerpo-Hadsall | Management Implications: • The Black-backed Woodpecker was a significant contributor to the establishment of bird and small mammal species and communities in areas with high burn intensities, and it appeared to have a more narrow range of suitable habitat conditions for nest site selection compared to the Hairy Woodpecker. Thus, the habitat requirements of the Black-backed Woodpecker serve as a useful threshold for managing burned sites for wildlife recovery. • Currently, post-fire harvest prescriptions in the Angora fire footprint prescribe the removal of all small snags and retention of approximately 5-10 large snags per hectare for wildlife use. The removal of most or all small snags within a burned area is likely to render the site unsuitable for Black-backed Woodpecker nesting. *** See www.fs.fed.us/PSW/partnerships/tahoescience for additional management implications. |
