Selected Plants of Navajo Rangelands
(a.k.a. Big heavy, black jack, bull pine, ponderosa white )
Ponderosa pine is a large, long-lived, native forest tree common throughout the western United States. The height of mature trees ranges from 55 to 90 feet. Ponderosa pine seeds are consumed by a great many birds and small mammals such as mice, chipmunks, and tree squirrels. Snags in the mature pine forest provide a large number of species with nesting and roosting sites. Big game, such as deer and elk, also use the pine forests for food and shelter. Ponderosa pines are fire-adapted and may grow in an open, park-like structure.
When the needles are eaten during gestation, they can cause abortion in cattle.
