Influence of Stand Thinning on Snowshoe Hare Population Dynamics and Feeding Damage in Lodgepole Pine Forest

This study assessed the impact of snowshoe hare (Lepusamericanus Erxleben) feeding injuries on diameter and height growth of juvenile lodgepole pine (Pinuscontorta Dougl. var. latifolia Engelm.). Five-year growth increments of undamaged and damaged crop trees in control (unspaced) and spaced stands, 20 km east of Prince George, B.C., were compared using analysis of variance. Semigirdling (sublethal) damage clearly suppressed diameter growth of small diameter (control, 41–60 mm; spaced, 31–50 mm) trees, but had little effect on larger stems. Height increment was significantly reduced by semigirdling in all diameter classes except for the 61–80 mm class in the control. Surface area or amount of bark and vascular tissue removed had little effect on growth increments in the spaced stand. The recommendation to delay spacing until the average tree diameter is >60 mm to avoid snowshoe hare damage is further supported for diameter but not necessarily for height growth.

A research project was initiated in 1980 to study the effects of outbreaks of the mountain pine beetle (Dendroctonus ponderosae Hopkins) on lodgepole pine forest (Pinus contorta Dougl. ssp. latifolia) in Yellowstone National Park and surrounding areas. This native insect apparently has long been associated with lodgepole pine, and reports of small numbers of beetles can be found in Park records as early as 1925. However, in the late 1940's and early 1950's major outbreaks began to occur on the Caribou and Targhee National Forests immediately to the west and southwest of Yellowstone and Grand Teton National Parks. An outbreak in Grand Teton National Park and the adjacent Teton National Forest began in the 1950's, with an explosive increase in 1961 followed by an eventual subsidence in the late 1960's. The first major outbreak in Yellowstone National Park began in the late 1960's in the Bechler and South Entrance areas, reaching a peak there in 1970 and later declining. Yearly aerial surveys conducted thereafter showed a steady northward movement of the outbreak through the western half of the Park at a rate of 1 - 5 km per year. By 1978 the peak outbreak was centered around West Yellowstone, with hundreds of infested trees per hectare. The outbreak is now moving north and east along the Madison and Gibbon Rivers, with the greatest beetle populations currently in the vicinity of Madison Junction.
