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 Crater Lake National Park disturbance (Leopold, ). Researchers note that.

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.

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. In Crater Lake National Park, Oregon, whitebark pine is the dominant tree on Wizard Island.

Sierra Nevada lodgepole pine is invading the island and appears to be replacing whitebark pine in importance. SEASONAL DEVELOPMENT: Male and new female cones are initiated from mid-July to mid-September, just prior to winter bud formation.

Fire, Fungi, and Beetle Influences on a Lodgepole Pine Ecosystem of South. Anthropogenic climate change is having significant impacts on montane and high-elevation areas globally. Warmer winter temperatures are driving reduced snowpack in the western USA with broad potential impacts on ecosystem dynamics of particular concern for protected areas.

Vegetation phenology is a sensitive indicator of ecological response to climate change and is associated with.

This paper describes the structure and composition of the vegetation, and some of the environmental factors controlling it, on km2 of Crater Lake National Park, Oregon. It also gives the approximate dates and locations of most fires that burned in the area between and We sampled the vegetation in 64 plots.

Wizard Island, a ½—square—mile volcanic cinder cone located in Crater Lake, Oregon, was sampled by continuous belt transects. Separation of the one herbaceous and four forested community types, which were mapped as major vegetation units, was remarkably distinct, as 60% of the herbaceous species were found in only one or two communities.

About lodgepole pines, Pinus contorta var. murrayana (Grev. and Balf.), growing in topoedaphic climax stands of south-central Oregon, were identified as having survived fires that occurred over a period from to All fires were natural wildfires, except for prescribed burns ofand The trees were sampled for bole and root damage to investigate fungal colonization.

Other Classifications and Key References The Lodgepole pine forest and woodland habitat includes the Pinus contorta zone of eastern Oregon and Washington listed in Franklin and Dyrness ().

It crosswalks to Oregon Gap vegetation types (in part), and Crater Lake National Park lies in the southern Cascade Mountains in south-central Oregon. The central feature of the park is the indigo lake located in the 4,ft-(1,m) deep caldera which was formed by the collapse of a 12,ft (3,m) composite volcanic mountain, Mt.

The large brooms in live trees may provide preferred habitat for some animals, but neither tree will make a full-size snag that is most valuable to wildlife (see dwarf mistletoe ecology. Sky-line camps. pp., illustrated.

The west side forests of Crater Lake National Park are unique in that they represent one of the few places in the Cascade Range where an elevational gradient from low-elevation mixed conifer to high-elevation mountain hemlock forests remains intact and has never been logged.
