In similar fashion, 90 percent of the diet of the northern spotted owl is composed of small mammals that are associated with non-coniferous vegetation.
Aside from supporting wildlife species, non-coniferous vegetation also makes important contributions to nutrient cycling, carbon sequestration, soil fertility, and aquatic food webs, the report said.
The report suggested that management options that include slower rates of conifer re-establishment, less-dense conifer plantations, more thinning of over-stocked forests, and less control of shrubs or other vegetation would all contribute to a wider diversity of vegetation and the wildlife species that depend on it, Hagar said. And the report noted it may take a while a decade or more for shrubs, herbs and broad-leaf trees to recover.
