What is the biome called that black tail deer lives in?

Black-tail deer live in forests and woodlands from California to Alaska. They are most commonly found in coniferous forests, such as Douglas-fir and pine forests, but they can also be found in deciduous forests, such as oak forests. Black-tail deer prefer areas with dense understory vegetation for cover, and they are often found near water sources. They are browsers and grazers, and their diet consists of leaves, twigs, grasses, and forbs.
