Abstract
When the forester finds planting necessary to regenerate an area he should know which species and class of planting stock is best suited to his particular operation. He should also weigh the expected successes on various locations which could be planted. Through such a procedure the best planting locations will be given priority and the best results, measured by survival and growth, will be obtained from the efforts expended. A test conducted at the Blacks Mountain Experimental Forest, an area typical of the California eastside pine type, has shown that survival of ponderosa pine (Pinus ponderosa Laws.) and Jeffrey pine (P. jeffreyi Grev. and Balf.) planting stock is strongly affected by the vegetation, logging slash, and stoniness of the ground at the points where the trees are planted.
In this experiment 1,200 trees were planted in the spring of 1951 on recently cutover land of various aspects. An equal number of ponderosa pine and Jeffrey pine were planted, half of each species being 1-0 and half 1-1 nursery stock. In planting, the trees were spaced 6 x 6 feet in a randomized block design. This note reports the results after two years.
