Hermit Warbler

Hermit Warbler
Forest condition: Mature/Young Forest (Multi-layered/understory reinitiating)
Habitat Attribute: Closed Canopy (of coniferous trees) forest patches >42 ha (101 ac) are necessary for their occurrence.

Habitat Objectives
Landscapes: At small landscape-levels (e.g., watersheds, townships, sections), provide >55% of the area as suitable nesting habitat (forest >40 years old with adequate canopy cover as described below), and >25% of the suitable habitat should be young forest. w
Sites: Where ecologically appropriate in forests >30 years old provide
– average tree dbh >30 cm (12 in)
– >90% canopy closure
– a dominance of Douglas-fir trees
Sites: Riparian buffer zones within harvest units should be >70 m (230 ft) wide to provide suitable habitat, and should meet site-level habitat conditions described above.

Habitat Conservation Strategies
– In forests managed for wood products, extend rotation ages to lengthen the period of time that the forest is available as suitable habitat.
– Conduct light to moderate thinning early in forest development (<30 years-old) to promote development of large crowns to increase habitat suitability later in forest development
