Loss of old-growth forest habitat on a landscape scale
Loss of the majority of low elevation old-growth forest habitat to development and other uses such as short-rotation timber production has greatly reduced the number of available nesting territories for northern goshawk.

Climate change
The effect of global climate change on northern goshawk and their prey populations is unknown. In the Pacific Northwest, global climate change models indicate that winter and summer temperatures in the region are likely to be warmer. Increased summer temperatures could result in a higher risk of forest fire, which could lead to loss of existing or developing nesting habitat. More information on the status of global climate change can be found on the US Global Change Research Program website.
