Available in PDF, EPUB and Kindle. Book excerpt: In a 1964-1967 study on the Challenge Experimental Forest, seedfall was evaluated in 2-, 5-, and 10-acre circular clearcuttings. During the 4 years, 10 seed crops, ranging from light to bumper, were produced by ponderosa pine. white fir, Douglas-fir, and incense cedar. Seedfall ranged from 76 to 40,691 sound seed per acre (188 to 100,547/ha) for a single species in a given year. From 89 to 100 percent of each species' seed fell within an area 1 1/2 times the height of the average dominant tree. Overall, seed distribution was highly variable.
Download or read book Mapping Pine Mortality by Aerial Photography Umstead State Park North Carolina written by Clarence J. DeMars and published by . This book was released on 1982 with total page 20 pages. Available in PDF, EPUB and Kindle. Book excerpt: In 1975-1976, pine trees killed by the southern pine beetle (Dendroctonus frontalis Zimm.) in a 2170-hectare (5362-acre) area at the William B. Umstead State Park in central North Carolina, were monitored by sequential color infrared aerial photography. From 1973 through summer 1975, beetles in 350 infestation spots killed more than 20,500 pines on 137 hectares (339 acres). From October 1975 to July 1976, an additional 301 dead pines were detected at 146 tree mortality centers. Southern pine beetles were associated with 98 percent of these dead trees. Pine mortality dropped rapidly from 248 trees killed in fall and winter at 120 spots to 9 trees killed in July at six spots. The volume of timber killed during the outbreak exceeded 16,000 m3 (7500 cords) of roundwood valued at more than $240,000. Strictly speaking, this is not an economic loss because the Park's management goal is to maintain a "natural forest."
