Quick Answer
Deer in California's D Zones rely heavily on specific food sources, including oak, tanoak, and madrone trees, which provide them with essential acorns and leaves. These trees are typically found in the state's coastal mountain ranges. The deer also forage for grasses, clover, and other forbs in the understory.
D-Zone Deer Food Sources: The Importance of Acorns
In California’s D Zones, white oak (Quercus lobata) and tanoak (Notholithocarpus densiflorus) trees are crucial for deer nutrition. Acorns from these trees make up a significant portion of a deer’s diet, especially during the fall and winter months when other food sources are scarce. To attract deer, consider planting these tree species on your property, aiming for a density of 1-2 trees per acre.
Deer Habitat: The Role of Grasses and Forbs
In addition to oaks, deer in the D Zones also rely on grasses and forbs as a food source. Forbs, such as clover and vetch, are particularly attractive to deer due to their high protein content. When creating deer habitat, consider planting a mix of grasses and forbs, including species like orchard grass and sweet clover. Aim for a mix of 30-40% grasses and 60-70% forbs to provide a balanced food source for deer.
Tips for Creating Deer-Friendly Habitats
When creating a deer-friendly habitat in California’s D Zones, consider the following tips: use a mix of tree species to provide a diverse food source, plant grasses and forbs in a 3:2 or 2:3 ratio, and create a diverse understory with a mix of shrubs and forbs. Also, consider creating a “deer highway” by creating a narrow strip of habitat, about 10-20 feet wide, that connects different areas of your property. This will allow deer to move through the area without feeling confined.
