Black-Throated Gray Warbler
Forest Stage: Young/Pole forest
Habitat Attribute: Deciduous Canopy trees
Landscapes: Within small landscapes (e.g., watersheds, townships, sections), provide >30% of the area as young/ pole forest with site-level habitat conditions as described below.
Sites: Where ecologically appropriate in forests >30 years old provide
– >20% canopy cover of deciduous trees.
Sites: Riparian buffer zones within harvest units should be >55 m (180 ft) wide to provide suitable habitat, and should meet site-level habitat conditions described above.
Habitat Conservation Strategies
– Where deciduous trees occur, ensure persistence of these trees by thinning of conifers shading them out.
– If deciduous trees are not present, conduct thinning to open-up the canopy and allow for development of deciduous trees where ecologically appropriate (e.g., wet sites). Thinning should occur in patches and be variable spaced rather than uniform to minimize negative effects of reduced overstory canopy closure by maintaining some areas with high canopy closure.
– Under long rotations, conduct repeat thinning as necessary to maintain a deciduous canopy component and lengthen the suitability of the habitat for a longer period of time.
