This dataset contains 8 layers showing current and predicted ranges of subalpine fir (Abies lasiocarpa ). One layer demonstrates range according to current climate conditions averaged from the period 1950-1975. Six layers model predicted ranges according to two different IPCC scenarios according to their Canadian Climate Centre modeling and Analysis (CCCma) third generation general correlation models (CGCM3) A2 and B1, in the years 2020, 2050, and 2080. An 8th layer shows a continuous model of predicted occurrence for the period 1975-2006.
Early succession aspen and late succession conifer forests have different architecture and physiology affecting hydrologic transfer processes. An evaluation of water pools and fluxes was used to determine differences in the hydrologic dynamics between stands of quaking aspen (Populus tremuloides) and associated stands of mixed conifer consisting of white fir (Abies concolor), Douglas-fir (Pseudotsuga menziesii), and Engelmann spruce (Picea engelmannii). In 2005 and 2006, measurements of snow water accumulation, snow ablation (melt), soil water content, snowpack sublimation, and evapotranspiration (ET) were measured in adjacent aspen and conifer stands. Peak snow water equivalent (SWE) averaged 34–44% higher in...

The dataset contains 3 maps that show the current and predicted range of Subalpine fir (Abies lasiocarpa) in the Pacific Northwest region. The layers include: 1) the species range modeled under current climate conditions for 1950-75 2) a continuous model of the predicted range for 1950-2006 and 3) potential range expansion and contraction from 2000-2009.

Investigations of vegetation stress along non-paved roads treated with a range of magnesium chloride (MgCl2) application rates utilized 60 roadside and 79 drainage plots on 15 and 18 roads, respectively. Evaluations were completed of foliar damage, plant health, biotic and abiotic damage incidence and severity, soil and foliar chemistry and other common site and stand characteristics of Pinus contorta, Populus tremuloides, Picea engelmannii, Abies lasiocarpa, and lower elevation plots dominated by shrubs and grasses. High concentrations of soil magnesium and chloride (400?500 ppm), high foliar chloride (2,000?16,000 ppm depending on species) and high incidence of foliar damage were measured in roadside plots along...
