Fire is the most destructive enemy of the forests. A lighted match, cigarette, or cigar carelessly tossed aside, or a campfire left burning may result in a disastrous forest fire and the destruction of valuable forest cover. About 51 percent of the fires that occur in the Rocky Mountain Region are man-caused and are preventable. Visitors to the forests are urged to exercise the greatest care with fire, and to follow carefully the SIX RULES FOR PREVENTION OF FOREST FIRES printed elsewhere in this folder. ASK THE FOREST RANGERS The Montezuma National Forest is divided into five ranger districts, each of which is administered by a forest ranger, working under the direction of the forest supervisor. The rangers are always ready to furnish information to visitors and assist them in every way possible. The headquarters of the supervisor and the rangers are listed below: Forest Supervisor U. S. Forest Service, Mancos, Colo. Forest Ranger Mancos District, Mancos, Colo. Forest Ranger Dolores District, Dolores, Colo. Forest Ranger Glade District, Dolores, Colo.

Trees of the Montezuma National Forest CONIFERS PINES—Three species.—They have their needles gathered together at the base in bundles of from two to five. The cones are woody and pendent. Limber pine (_Pinus flexilis_).—Stout, dark-green needles, 1½ to 3 inches long, in bundles of five. Cones 3 to 10 inches long, with seeds about ⅓-inch in length. Cone scales smooth. Bark light gray, except on old trunks, which are blackish brown and furrowed. Ponderosa pine (_Pinus ponderosa_).—This tree was formerly known as western yellow pine. Needles 5 to 11 inches long, dark green, usually three in a cluster, but often in twos and in tufts at the ends of the branches. Cones 3 to 6 inches long, oval-shaped. Cone scales armed with spines. When young, the bark is dark, and the tree is known as “black jack” or “bull pine.” When older, the bark is reddish brown and occurs in thick, scaly ridges. Piñon or piñon pine (_Pinus edulis_).—Piñon is a short, scrubby tree, often growing in mixture with juniper, and is confined to the foothills. Needles usually in bundles of two, rarely three, ¾ to 1½ inches long. Cones 1½ inches long and almost as broad, containing large seeds, which are the piñon nuts of commerce. SPRUCES.—Two species. Needles scattered over the twigs singly. Needles are sharp-pointed, four-sided, leaving twigs rough like a grater when they fall off. Cones pendent, with parchmentlike scales, falling off the tree whole.
