For the past ten years, he and his colleagues have worked on the "Forest and Climate Change" research project, along with the Swiss Federal Institute for Forest, Snow, and Landscape Research (WSL).
With heavy year-round precipitation, this near-freezing winter temperature regime suggests that modest warming would dramatically reduce snow accumulation.
Will small evergreens covered by snow be harmed? …
But a refuge won't help the whitebark pine, and so now scientists are pondering a simple but radical new idea: moving the trees to where they will be more comfortable in the future.
Douglas-fir will be largely eliminated from California and coastal Oregon where it is now the most important timber species.
The reductions in range are predicted as a direct effect of higher temperatures and drought stress on growth, and perhaps as the result of failure to meet winter chilling requirements.

Phomopsis Dieback, Azalea Dieback is caused by the oomycete, or water mold, Phomopsis rhododendri. Typically, dying branches (stem dieback) begin to appear on an otherwise healthy plant. The leaves die and can remain attached to the plant until late summer. Usually a single branch on an established plant is affected. Scraping away the bark with a knife reveals discolored wood under the bark that appears chocolate brown. Dieback is difficult to control on azaleas in the landscape. The azalea varieties that are the least susceptible include: 'Delaware Valley White,' 'Hershey Red,' 'Pink Gumpo' and 'Snow.' Reduce stress to the plants by planting in partial shade and watering during dry periods. Avoid wounding the plant. Prune infected branches well below all discolored wood and dispose of dead plant material. Clean pruning tools between cuts with a dilute solution of household bleach (1 part bleach to 9 parts water). Also see , and .
Deer Netting: To prevent winter deer damage you need to take prompt action in the fall and subsequent falls to insure it doesn't happen again. I used a product found in hardware stores called deer netting. It is similar to bird netting but heavier and courser. I wrapped groups of plants together and wrapped isolated plants individually. I fastened it on with tie wraps or twine and just cut the tie wraps or untied the twine in the spring. The important thing is to take deer netting off in the spring before the rhododendrons and azaleas sprout and grow through it. If the foliage does grow through the netting, the netting is very hard to remove without damaging the plants. Also, the portion of the plant that grows through the fence is no longer protected. The deer netting is good in that it doesn't get covered with snow unless it is a very wet snow. Otherwise the snow just goes through it.

Q: I have 4 Spring Snow crabapple trees (about 8 — 10 years old) planted in a line about 10' apart in a flower bed. 3 of the trees have always been good with flowers and leaves. One tree (a middle tree) is not growing as vigorously, and although it blooms, it gets very few leaves in the summer. It has been doing this for about 4 years. What should I check for to determine why this tree is not thriving like the others?

The sub-boreal spruce zone is found in British Columbia in the central plateau between the and Cariboo–Rocky Mountains. It has slightly cooler summers due to more cloud cover, shorter lengths of days and less severe winters with more snow than the boreal white and black spruce zone. The forests are dominated by hybrid white spruce, subalpine , lodgepole pine, Douglas fir, black spruce and black cottonwood with some trembling and paper birch forests, particularly where there are lots of fires.

Lifecycle: This insect has a 2-year lifecycle with most of its lifecycle spend in the soil. All development occurs during the first year and the insect remains deep in the soil in hibernation for the second year before emerging the third spring. Offspring from odd-year emerging adults will emerge as adults the following odd year (2007 2009). Adult: All adults are females and there are no known males in the North American population. Adults emerge from deep in the soil during the first week of May and feed on the foliage of a wide array of plants. Host plants include alfalfa, clover, rhubarb, grapes and roses. After about 3 weeks of feeding, the adults begin to lay eggs around the base of host plants. Economically, the most important plants are alfalfa and clover. Oviposition continues for about 4-6 weeks with each female laying between 150-300 eggs.
Larvae: The major economic damage to alfalfa and clover is caused by larval feeding on the roots of the plant. Small larvae feed on the secondary roots causing root pruning and reduction of the root system. As the larvae grow larger, they move to the main tap root where they girdle the tap root with longitudinal spiral feeding. As the larvae enter the last two larval instars, they sever the tap root and often feed up into the interior of the tap root. Larval feeding starts in early June with the feeding on the secondary roots and the larger larvae finish their feeding with sever root damage in the fall during October and November. Plant death from root feeding damage started in late summer and continues throughout the winter. Farmers are greeted in the spring with large areas of their alfalfa fields dead and devoid of plants (pure stands) or in mixed stands with grass, a hay field composed completely of grass without alfalfa.

This is the subalpine region further inland from the coast. In this region, the ground usually freezes before the snow falls. Two zones are recognized. The first, the Engelmann spruce–subalpine fir zone, occurs commonly in and . Typical tree species include Engelmann , subalpine , lodgepole and whitebark and subalpine .
