Predators, such as brown bears, disperse these marine nutrients into surrounding forests, enhancing the growth of stream-side trees that shade and protect stream banks from excessive erosion. In southeastern Alaska, spawning salmon contribute up to 25% of the nitrogen in the foliage of trees, resulting in tree growth rates nearly three-times. Explanation of WAM.

Abstract. 9 p Topics: Water temperature--Alaska., Clearcutting--Alaska Author: William R. Meehan. meet specified temperature reductions. Stream banks and hillsides contribute to shading, especially in narrow, deeply incised streams.
The amount of shading by the banks depends not only on their height but also on the elevation angle of the sun and the orientation of the sun relative to the stream channel. Riparian vegetation affects stream temperature in three main ways.

Drought induced changes in stream flow and temperature will affect ALL freshwater salmon life stages. in outheast Alaska (Meacham and Clark ) and in some watersheds and timber ha vest has been and is still a concern (Koski et al. ; Murphy et al.
; Thedinga et il. However, the large land base, low human population, and numerous int ct watersheds throughout southeast Alaska mitigate these effects on a regionCited by: Trees can only survive above the highest winter waves, but seasonal wildflowers can take advantage of the summer sun and smaller waves by colonizing small pockets of soil.
The forests of Southeast Alaska form a tall canopy that shades a dense ground cover of mosses, ferns, and a variety of bushes. PEOPLE. Alaskans are a very kind bunch as a whole, politics aside, and residents of Southeast are no exception.
As I did hours of research for my next book, Alaska on the Go: exploring the Marine Highway System with children, I find myself chatting up folks who grew up under the mantra of “do unto others,” a manner of living that appears wherever we go. The University of Alaska Cooperative Extension Service publishes a list of plant sources for Alaska.
Plant species with low shade tolerance in sunny areas. Do not apply lime to soil near plants with low or moderate acid tolerance.
Finding the plants that grow well in shade can be challenging but is not impossible. There are many perennials that will grow nicely for us in the shade and this list is not exhaustive. Our particular lot has many birch trees and has posed a challenge to grow plants that need more light and it has become clear to me that shade plants love it here.
It has taken a while to find the right fit of. Winter time precipitation in Southeast Alaska falls in many forms. Examples include rain, snow, sleet, and freezing rain. Sleet is small pieces of ice that bounce when they hit the ground. Freezing rain falls as liquid but freezes upon impact with the ground and exposed objects.
“Freezing spray is a water marine hazard in Southeast Alaska. Alaska has seen its warmest summer on record, and every aspect of the state's environment is impacted, from the southeastern temperate forests to the ecosystems of the Bering Sea.
Climate change effects on the wildlife in temperate rainforests in the southeast region will be influenced by decreasing snow-pack and lengthening of the growing-season.
Snow depth impacts foraging and herbivore animals such as blacktailed deer (Odocoileus hemionus), moose, and mountain goat (Oreamnos americanus). The NCA Education Resources for the Alaska Region features guiding questions, key figures, related resources, reviewed lesson plans, videos for all of the NCA key messages for each region.
The site contains information that will help educators and students gain a deeper understanding of climate science and the implications for the nation.
Alaska Department of Fish and Game P.O. Box W. 8th Street Juneau, AK Office Locations. Climate change in southeast Alaska are changes which occur in southeast Alaska as average temperatures rise as a result of global warming.
The temperate rainforest that covers this area is a result of humid summers and transient snow cover in winter. The conifers that thrive in this moist climate are free from fire risk as compared to the forests to both the north and south.
The climate of the interior of Alaska is best described as extreme and is an excellent example of a true continental subarctic climate.
Some of the hottest and coldest temperatures in Alaska occur around the area near Fairbanks. The summers can have temperatures reaching into the 90s °F (near 34 °C), while in the winter, the temperature can fall below −50 °F (− °C), and in rare cases, below −60 °F.

From the below temperatures of the Interior to the twenty-four hours of daylight in a northern summer, Alaska’s climate presents challenges to its Cited by: lower atmosphere. The greenhouse gases radiate some of the trapped energy back to the earth’s surface, adding heat to the earth’s surface that would otherwise be lost to space.
Without a natural greenhouse effect, the temperature of the Earth would be about 0°F instead of its present 57°F. The concern is not the fact that the greenhouse. About Alaska Tourism is a major industry in Alaska, and an important part of enjoying a visit to our beautiful state is being prepared to deal with our widely-varying and ever-changing weather.
We often get requests from visitors to our web site who are planning a trip to Alaska (i.e., Southeast Alaska), and who are interested in weather. The Alaska Panhandle is best visited in the summer, when temperatures are milder and spawning salmon attract wildlife to the coast. Given how isolated this part of the state is, it’s best to Author: Christina Liao.What Climate Change.
