The Restoration of Sitka Blacktail Deer Habitat: Part 1
1 天前 · A Sitka blacktail buck and brown bear in northern Southeast Alaska. Deer populations are influenced dramatically by winter weather, and some of the recent die-offs have been near apocalyptic. Diminished old growth wintering habitat and lack of forest connectivity contributes to deer declines. In the past, logging efforts in Southeast Alaska ...
Sitka black-tailed deer habitat selection in relation to logging and ...
2024年9月15日 · To explore the response of Sitka black-tailed deer (Odocoileus hemionus sitkensis) to commercial forestry we performed habitat selection analyses (HSAs) based on data across 3 spatial scales (step selection, home range, and study area) and 4 seasons in relation to logging-related covariates (logged areas and roads) and LiDAR-derived vegetation ...
Sitka Black-tailed Deer Species Profile, Alaska Department of Fish and Game
Deer have inhabited northern Southeast Alaska since their migration from southern refugia following the Pleistocene epoch. Deep snow keeps the number of deer on the mainland lower than that on adjacent islands. A population estimate suggests about 200,000 deer in Southeast Alaska (Merriam 1970).
The natural range of Sitka black-tailed deer in both British Columbia and Southeast closely overlaps the . distribution of the coastal temperate rainforest. Deer use a variety of habitat types throughout the year from sea-level beaches, through valley-bottom forest stands, to alpine ridges more than 3,000 ft (915 m) above sea level (Fig 7).
habitat are considered the most important limiting factors for Sitka black -tailed deer in Southeast Alaska. Research conducted in Southeast Alaska indicates that high- volume mature forests at low elevations are needed during severe winters (Yeo and Peek, 1992). The Sitka black -tailed deer is an important game and subsistence species.
spruce forest in southeastern Alaska is an important element of the habitat of Sitka black-tailed deer. The conversion of uneven-aged, old-growth forests to even-aged, second-growth forests has generated concern about the future carrying capacity of the habitat for deer, especially where snow accumulation is common on winter ranges. Even-aged,
Spatial analysis of habitat selection by Sitka black-tailed deer in ...
We used a vector-based geographic information system (GIS) to examine habitat selection by radiocollared Sitka black-tailed deer (Odocoileus hemionus sitkensis) in logged forests of southeast Alaska. Our main objective was to explain deer habitat selection relative to old-growth/clear-cut edges and edge habitats at two different spatial scales.
New Approach to Sitka Deer -- Habitat Modeling, Alaska …
Scientists now have a new — and improved — model for predicting winter habitat use by Sitka black-tailed deer on Prince of Wales Island, laying the groundwork for wildlife management, habitat restoration efforts, and applications for future …
Using LiDAR and Random Forest to improve deer habitat models in …
2021年11月1日 · A LiDAR-based winter habitat model for Sitka black-tailed deer using a Random Forest machine learning algorithm on Prince of Wales Island in southeast Alaska, USA, during 2010–2012. All deer GPS locations are buffered by 100 m for visual purposes.
Seeing the Forest for the Deer: Alaskan Scientists Harness Big …
2022年5月11日 · The Sitka black-tailed deer’s range extends throughout the forests of Southeast Alaska and British Columbia. They’re unlikely to show up in the fringes of human settlement. In fact, their numbers are directly tied to the health of the places where you find them: the temperate coastal rainforest, with its mix of towering Sitka spruce ...
