36 Experiment Station Bulletin 345 



Nineteen of these plantations have been established to date with an 

 aggregate area of 12.65 acres. Four new ones will be established this 

 coming spring with an estimated acreage of 2.35 acres. 



Tables of survival since 1939 have been compiled, also growth tables 

 for some sixteen species of soft and hardwood trees. 



Series C: Game Food Species, 1941 to date. Plantations of food- 

 I tearing trees and shrubs which are important in wild life management 

 have been grouped in this series. These plantations may eventually be 

 made in plots, but at present they are distributed as a row along a road, 

 trail, or fire line. The usual number of sample trees are staked and 

 examined for growth and condition 1, 2, 5, and 10 years after planting. Peri- 

 odic examination will include data on fruit production, use by game, and 

 other pertinent information. 



Series D: Tenth-acre Plots, 1941 to date. These plots will include 

 a wide variety of species, local and exotic, valuable and unimportant, trees 

 and shrubs. Ten rows of ten each will be set in square plots, one-tenth 

 acre in size. The plots will be arranged in checkerboard fashion with the 

 alternate plots kept open. Each tree will be given a number, and com- 

 plete records will be kept covering growth and condition. Root growth 

 and root habit will be studied, as well as other silvical characteristics, 

 such as formation of litter, effect on soil, crown closure and self pruning, 

 crown density, maintenance of canopy, and duration and rapidity of 

 height growth. The plots will also include material collected for the 

 study of races and selective breeding. It is not expected that these planta- 

 tions will be permitted to reach maturity, as some of the studies will involve 

 destruction of the trees examined. This is the fundamental difference 

 between these plots and those in Series A, B, and C. 



Last year fifteen plots were established. Owing to the extremely 

 dry summer, the mortality was very high and the average survival for 

 nine coniferous species was only 56 per cent. For six deciduous species 

 it was 39 per cent. Four of the plots were complete failures. This spring 

 we are putting in four new plots, two of them second plantings of species 

 tried out a year ago. 



Series E: Direct Seeding, 1940 to date. All experiments in the 

 establishment of stands by direct seeding will be brought together in this 

 series. The information recorded will be as complete as seems necessary, 

 covering not only the quantity and source of seed and the method of 

 seeding but also the growth and development of the resulting stand. Since 

 direct seeding was included in the original description of the project as 

 set up by Professor Foster in 1913, it does not seem out of place to in- 

 clude it under the title "Plantation Studies." Unfortunately, however, 

 no such experiment has ever been started, or at least we have record of 

 none. It is now a part of our regular program to attempt at least one 

 direct seeding each year. 



Series I ■'.- Coppice Reproduction, 1941 to date. Since plantation 

 studies are essentially studies of forest reproduction, it would seem ad- 

 visable to include in this project an examination of the results obtained 

 when a stand of hardwoods is regenerated by means of stump sprouts. 

 There is little information available in the literature concerning this 

 method.
