Download or read book Ponderosa Pine Mortality Resulting from a Mountain Pine Beetle Outbreak written by William F. McCambridge and published by . This book was released on 1982 with total page 12 pages. Available in PDF, EPUB and Kindle. Book excerpt: From 1965 to 1978, mountain pine beetles killed 25% of the pines taller than 4.5 feet in a study area in north-central Colorado. Average basal area was reduced from 92 to 58 square feet per acre. Mortality increased with tree diameter up to about 9 inches d.b.h. Larger trees appeared to be killed at random. Mortality was directly related to number of trees per acre and presence of dwarf mistletoe, but not to site index, elevation, and percent Douglas-fir in the stand.

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."

Download or read book Mapping Mountain Pine Beetle-attacked Ponderosa Pine from High-resolution Imagery written by and published by . This book was released on 2015 with total page 17 pages. Available in PDF, EPUB and Kindle. Book excerpt: The mountain pine beetle (MPB) (Dendroctonus ponderosae) has killed millions of acres of pines throughout the western United States in recent years. Active control of the beetle has been hindered by the inability to detect infested trees prior to obvious visual signs. With sponsorship from the Forest Service, U.S. Department of Agriculture (USFS) Remote Sensing Steering Committee, the Remote Sensing Applications Center in collaboration with the Black Hills National Forest (NF), conducted a study to determine the feasibility of pre-visual detection of MPB-infested ponderosa pine by analyzing a time series of 26 high-resolution, 8-band, multispectral WorldView-2 (WV2) images of the Black Hills NF. Based on spectral and trend analyses of the time series data, the first sign of detection occurred around mid-March to April. Unfortunately, the newly attacked trees could not be detected early enough for the management goals of the Black Hills NF. Therefore, the emphasis of the project shifted to developing a semi-automated method to map the red-attack stage of the trees from high-resolution aerial photography and SPOT 6 imagery. The red-attack trees were mapped from the aerial photography using eCognition software across an area of approximately one million acres. In many areas, the results were exceptional, with very few errors; however, in areas of sparse or thinned forest, significant errors of omission and commission occurred. Despite the errors, the semi-automated process may still provide sufficient benefit to reduce the time and cost of mapping the trees as compared to traditional manual delineation methods.
