Grant history of an LTER site
Harmon 0218088 The Andrews LTER program seeks to understand the long-term dynamics of forest and river ecosystems of the Pacific Northwest. The Central Question guiding Andrews LTER research is: How do land use, natural disturbances, and climate change affect three key sets of ecosystem services: carbon and nutrient dynamics, biodiversity, and hydrology? These ecosystem services… Read more »
The Andrews Forest is located in the western Cascade Mountains of Oregon, one of six original Long-Term Ecological Research projects that began in 1980. It was built on a long research history by the Forest Service and has a record of ground-breaking science and application to forest management and conservation. The terrain is mountainous and… Read more »
Climate change forecasts for the Pacific Northwest portend drought, decreased snow packs, and increased wildfire. Predictions for how Pacific Northwest ecosystems will respond to climate change face both scientific and social challenges. First, observed rates of climate change in this region vary in both space and time. Second, forest governance systems face conflicting pressures to… Read more »
The Pacific Northwest is experiencing increased drought and wildfire, and decreased snow packs. There is much uncertainty about how its ecosystems of forests, streams, and mountain meadows will respond. Ecologically, these habitats are experiencing environmental changes in very different ways. Socially, public values associated with these areas vary greatly and can be in conflict with… Read more »
During the first five years of the Arctic LTER at Toolik Lake, Alaska, systematic measurements of climate, of tundra plant distribution and productivity, and of lake and stream physics, chemistry and biology were begun. Whole system experiments were set up on the tundra, in streams, and in lakes to examine the ecological effects of changes… Read more »
9810222 Hobbie The Arctic LTER site is located in the northern foothills of the Brooks Range, Alaska, in tundra vegetation of sedges and grasses mixed with dwarf birch and low willows. The tundra, streams and lakes at the site have been undisturbed and unchanged for more than 5,000 years. This allows the analysis of relationships… Read more »
This is the fourth stage of the Arctic LTER (ARC) located at the Toolik Lake Field Station, Alaska, where the ecology of tundra, streams, and lakes is studied to understand controls on ecosystem structure and function within the long-term goal of predicting the effects of environmental change. Research has been ongoing at the station since… Read more »
This award supports the fifth phase of the Long Term Ecological Research Site (ARC LTER) at Toolik Lake, AK. The arctic region has warmed significantly over the past 30 years and arctic lands and freshwaters are already changing in response. The changes include a general “greening” of the arctic landscape, changes in species distributions and… Read more »
The Arctic is one of the fastest warming regions on Earth and as such may well provide an idea of the future changes likely to occur further south. This warming has increased disturbances such as wildfire as well as thawing of permafrost in ecosystems of Northern Alaska. As a result of this warming and increased… Read more »
