58 EXPERIMENT STATION RECORD (Vol. 92
Particular attention was devoted in the study to the loblolly-shortleaf pine type
of forest land. In 1943, this type was producing at less than one-half its potential
capacity. However, the complicated ownership picture makes difficult the development
of a unified plan for managing such areas. The State has a social responsibility
in reconciling the divergent views of forest landowners. A plan is set forth
for achieving this objective. The situation on the longleaf-slash pine and bottomland
hardwood types of forest land are also discussed, and plans for improvement
are set forth.
A ten-year ecological study of adjoining grazed and ungrazed woodlands in
northeastern Ohio, C. A. DAMBACH. (Ohio State Univ.). (Ecol. Monog., 14
(1944), No. 3, pp. 255-270, illus. 9).-In the 10 years following discontinuance of
grazing in a sugar maple woodlot in Geauga County, Ohio, there was a marked
restoration in the flora and fauna population and an increase in economic returns
as compared with an adjacent area upon which pasturing was continued. Seedling
trees became established in large numbers in the third season following fencing. In
the eighth growing season there were nearly 80,000 .seedling trees per acre in the
protected area. Sugar maple seedlings dominated, but there were 18 other species
present in small numbers. The development of herbaceous and shrubby species
followed a similar pattern and there was a notable increase in leaf litter in the
ungrazed area. Birds and mammals also increased in number and kinds. The
average yearly income from the sale of maple products was $10.67 more per acre
in the protected than in the grazed areas.
Volunteers in Ohio forest plantations, R. R. PATON. (Ohio Expt. Sta.).
(Jour. Forestry, 42 (1944), No. 6, pp. 420-422, illus. 2).-A survey of over 2,500
plantations in various parts of Ohio showed that 76 percent had volunteers averaging
541 per acre. The number of volunteers tended to increase up to 25 yr. of age,
after which there was a decrease. One of the chief factors involved in the establishment
of volunteers was the availability of seed. The species of volunteers varied
greatly in relative abundance in the different regions of the State, with elm, cherry,
hawthorn, white ash, and sugar maple taking the lead for the State as a whole.
Birds and wind ranked high as distributors of seed.
Watering plantation trees, R. H. WEIDMAN and C. R. BERRIMAN. (U. S. D. A.
coop. Univ. Calif.). (Jour. Forestry, 42 (1944), No. 6, pp. 435-437).-Distinct
advantage was obtained from watering plantations in the foothills of the Sierra
Nevada range, where summer rainfall was almost zero. Mulching with needle litter
was valuable as a supplement to watering, particularly to moderate or light watering.
Although the watering of extensive forest planting is not feasible, it is believed that
watering during the first season would be worth while in the case of farm, forests,
windbreaks, erosion-control plantings, and arboretums.
Tree planting and soil erosion control in the Southwest, R. E. WILSON.
(U. S. D. A.). (Jour. Forestry, 42 (1944), No. 9, pp. 668-673).-At the head of
the list of trees for planting in the Southwest for soil erosion control is the native
cottonwood, on account of its hardiness and resistance to drought. Where there is
sufficient water, willows rank high because of their rapid early growth. The best
willow is Salix fragilis, which is capable of making 6 to 8 ft. of growth per year
in its early period. The Russian-olive has much value because of rapid growth,
resistance to alkali, and capacity to form thick sturdy stands. The evergreen
tamarisk, or Athel tree, of Mediterranean origin has much promise wherever an
adequate supply of water is available. On the other hand eastern species such as
elm, locust, ash, wild plum and Osage-orange are not promising in the Southwest
because of slow growth and difficulty to establish.
