The Forest Service, for which authority much of the above discussion of this species was taken, offers the following general outline for management in California:
"Since the forests in which sugar and yellow pine occur vary greatly in composition, the method of treatment must also vary. For this the forest types already distinguished may form a basis.
"On the lower portion of the sugar pine-yellow pine type, where sugar pine forms but a small proportion of the stand, only the yellow pine should be considered for the future forest. All merchantable sugar pine may therefore be removed. It will be necessary to leave only a few seed trees of yellow pine to restock the ground, although usually it will be a wiser policy to leave a fair stand, since this can be removed as a second cutting when reproduction is established. This procedure would also hold for areas on which yellow pine occurs in nearly pure stands. In these localities dense stands of second-growth yellow pine occur. It will often be profitable, where there is a market at hand, to thin these stands when they are about 30 years old, removing the suppressed trees for mine props. Trees 6, 8 and 10 inches and up are used for this purpose, and sell for from 5 to 6 cents a running foot.
"On the upper portion of the sugar pine-yellow pine type, where both species have about an equal representation in the stand, seed trees of each should be left, wherever practicable, in the proportion of two sugar pines to one yellow pine."
In the fir belt, where sugar pine and fir are the principal species, the fir should be cut clean wherever possible and sugar pine should be relied upon for the future forest.
"On all lands, the Douglas spruce, white fir and incense cedar should be cut whenever possible, and chutes, skidways and bridges should be constructed from the two last named species."
The following specific instructions are issued for marking timber on National Forest sales in the sugar pine-yellow pine type:
"Owing to the large size of the trees, marking in this type of forest should be done with special care, since a slight mistake involves a comparatively large amount of timber.
"On nearly all of the lands included in this type the ground is now but partly and insufficiently stocked with young timber, the areas of forest are constantly becoming more accessible to markets, and there is every indication of a strong future demand at greatly increased prices. On nearly every tract, a second cut can be made within thirty years. All marking under present sales should be done strictly with reference to two points:
"1. Stocking the cut-over land as fully as possible with sugar and yellow pine.
