THE VEGETATION DYNAMICS OF PINUS CONTORTA FOREST, CRATER LAKE NATIONAL PARK, OREGON INTRODUCTION One objective of the National Park System is to preserve pro-tected areas in their pristine condition. Achieving this may involve perpetuating natural processes, such as fire, rather than simply eliminating disturbance (Leopold, ). Researchers note that. Get this from a library!

The vegetation dynamics of Pinus contorta forest, Crater Lake National Park in the southern Oregon Cascade Range. were surveyed at Crater Lake National Park to investigate potential. Crater Lake National Park's forests are significant in that they are mostly old growth. They form the bulk of the park's vegetation and define the park's landscape. The forest environments at Crater Lake are diverse and dramatic. Conifers dominate the park’s forests but a few deciduous species highlight streams and open areas. Whitebark pine (Pinus albicaulis. Engelm.) is vulnerable to a number of threats including an introduced pathogen (Cronartium ribicola J.C. Fisch.), epidemic levels of native mountain pine beetle (Dendroctonus ponderosae Hopkins), fire suppression, and climate change. To describe the structure of whitebark pine populations in two national parks in the southern Cascades (Crater Lake, Oregon, USA.

Legacy effects from one disturbance may influence successional pathways by amplifying or buffering forest regeneration after the next disturbance. We assessed vegetation and tree regeneration in non-serotinous Sierra lodgepole pine (Pinus contorta var. murrayana) stands after a wildfire which burned with variable severity and again after a high-severity subsequent fire in This history records the first large-scale project to control bark beetle in a National Park in the Pacific Northwest. The epidemic of Dendroctonus ponderosae on Pinus contorta in Crater Lake National Park, Oregon, began in the early s. The beetle was controlled either by burning felled trees or, in seasons of high fire danger, by exposing infested logs to solar radiation. Crater Lake National Park. Forest Zones. Park forests are composed mostly of conifers, although a few hardwood species can be found. There are four major forest zones at Crater Lake National Park, each named after its dominant tree species. Starting in the park’s lower elevations (about 4, feet or 1, meters), ponderosa pine forest is the.
