APPENDIX D3: Report on the Survey and Examination of Forest Reserves, March 1898

Sheep do not feed on the leaves or seedlings of coniferous trees, except in the way of desultory nibbling or when at the point of starvation. The harm which they do is of another character altogether. The seedlings of conifers are small and very susceptible to injury during their early life. When a band of sheep passes over an area on which such seedlings grow the trampling of the sharp hoofs not only cuts and bruises the young trees, but it also exposes their roots, and so leads directly to their destruction. On dry slopes, where reproduction is difficult at best, the passage of a band of sheep makes it simply impossible until a new crop of seedlings can replace those which have been destroyed. It is in this way, and not at all by injury to the old trees (an alleged fact frequently contradicted by sheep men), that sheep hurt the forest.

In so far as sheep tend to destroy or prevent a dense forest cover, they injure the water supply, and that they have done both to some extent, at least indirectly, is evident. The effect of their action is not believed , however, to have been seriously felt hitherto. In this connection it may be well to add that actual observations at Fort Klamath and Government Camp, quoted by Mr. Coville, indicate that snow lasts about six weeks longer in the forest than in the open.

It is believed that the reproduction of considerable parts of the eastern slope may be postponed with safety to the forest, and that in consequence sheep herding may there be permitted under suitable restrictions. The importance of this industry to the three counties where the sheep are chiefly owned (Wasco, Crook, and Sherman) is so great that its sudden prohibition within the reserve would work great hardships. Under the circumstances, the wiser course appears to be to permit the pasturage of definite numbers of sheep on definite ranges for the present, and in a tentative spirit, throwing the burden of the prevention of the forest fires upon the sheep owners, and in general following the course advocated by Mr. Coville and summarized in Part II of this report. It should not be forgotten that overgrazing will lead to the extension of the ranges by means of fire. For a more extended treatment of this subject, reference is made to Mr. Coville’s admirable report, in the conclusions of which I fully concur.

THE FOREST, WESTERN SLOPE.

The forest of the western slope is tall, dense, moist, and rich in valuable kinds of trees. The range is more heavily timbered in its northern and central portions than toward the south, but the forest throughout is very valuable, rapid, or fairly rapid in growth, and of great prospective commercial importance.

The most important tree is the Douglas fir (red fir), which reaches in places a height of over 250 feet and a diameter near the ground of from 10 to 12 feet. It forms very extensive forests on the lower slopes, sometimes almost without admixture of other trees. The reproduction is wonderfully good in places, especially in the open. Up to an elevation of 2,000 feet this is the most plentiful tree.

The western hemlock has great reproductive powers, and young trees of this species are plentiful in the forest, especially on fallen logs and dead stumps. Its wood is valuable for lumber, but has been little used hitherto. Its average dimensions may he given as follows: Height, 125 feet; diameter, 3 feet: length of clear trunk, 40 feet.

The western cedar, while of less size here than nearer the coast, is still a large tree of great economic value. It prefers moist land, has good reproductive powers, both within the forest and in the open, and will be one of the first trees cut in many localities.
