Reforestation on harsh, high-elevation sites near the crest of the Cascade Mountains can be challenging because of persistent snowpack and extreme climatic variation. To help find a solution to meet this challenge, the use of tree shelters was investigated with two species, Douglas-fir and western larch on two Yakama nation sites across three fall planting dates.

High-elevation sites in the eastern Cascades of Washington have a short period of favorable spring planting conditions followed by a short growing season. In addition, rapid changes in soil moisture, temperature, relative humidity, and solar radiation make plantation establishment on these sites more challenging than on lower-elevation sites Most soil moisture on these sites result from snowmelt with very little additional precipitation from spring through fall. The snowpack insulates the ground and young seedlings from constantly changing and potentially deadly temperatures and winds during the winter months; but once the snowpack melts, the seedling environment changes rapidly from wet and cold to hot and dry.

NORTH BRUNSWICK — Students at John Adams Elementary School were “energized” last week even though they had to stay after school.

Members of the fourth-grade gifted and talented program listened to a presentation Jan. 6 by Ray Kuehner, an energy specialist for the North Brunswick school district.

Within the district, Kuehner said heating, cooling, electric and gas costs total about $3 million a year.

“It’s a lot of money. A lot of money,” he said.

However, he said the district is taking measures to save energy and money. By doing “simple things,” he said, about $500,000 has already been saved.

“We are able to put it back into our education budget to buy books and other things you guys need to learn,” he said.

One important change within the district has been shutting off lights when a room is empty. Another is opening shades to let in light and warmth when the weather is cold, and shutting them to block out the cold or extreme summer heat.

In addition, the lights have been disconnected on the 20 vending machines at Linwood Middle School and North Brunswick Township High School, saving about $100 per machine per year, or about $2,000 total.
