2 _Wind River Experimental Forest, where forest research began in the Pacific Northwest, near Carson, Wash., Gifford Pinchot National Forest, Pacific Northwest Region._
The arboretum is a proving ground for conifers of the world and now has groups of more than 135 species. Separate areas are devoted to shade tolerance, seed dissemination, rodent control, and other studies. And nearby at the Wind River Nursery, about 5.5 million new trees are produced yearly for reforestation in the Northwest.
3 _Institute of Forest Genetics near Placerville, Calif., Eldorado National Forest, California Region._
The Eddy Arboretum, named for its founder James G. Eddy, contains species of pines from all over the world: 70 species, 35 additional varieties, and 90 different hybrids. It was established in 1925 for breeding and improving this group of timber trees. The Institute, working to propagate faster growing, disease-resistant trees, is successfully crossbreeding species such as Jeffrey and Coulter pines into superior strains.
4 _Town Creek Plantations, Centerville, Idaho, north of Idaho City Ranger Station, Boise National Forest, Intermountain Region._
This 200 acres of new forest was dedicated to the youth of Idaho in 1955, on the 50th anniversary of the Forest Service. Ponderosa pine plantings were made with different techniques every year for 5 years and are being studied in order to develop best methods for regeneration.
5 _Kaibab Plateau, managed timber areas near Jacob Lake, Ariz., Kaibab National Forest, Southwestern Region._
The Kaibab Plateau, 60 miles long and 40 miles wide, is rich in scenery, water, wildlife, and timber (ponderosa pine and Douglas-fir). Once the population of the great Kaibab deer herd reached 100,000, far beyond the capacity of the range. Trees were destroyed by wildlife, and thousands of deer died of starvation. Public hunting now keeps the herd in balance.
6 _Trees for Tomorrow Camp, Eagle River, Wis., Nicolet National Forest, North Central Region._
The marked nature trail demonstrates how the forest lives and grows, its relationship with other natural resources, and how man supplements Nature’s management. This camp is operated by Wisconsin wood industries in cooperation with the Forest Service as a school primarily for high school and college students and teachers in conservation.
