T HE CHANCE TO SEE a wild grizzly bear is often the first or second reason people give for visiting Yellow - stone National Park. Public interest in bears is closely coupled with a desire to perpetuate this wild symbol of the American West. Grizzly bears have long been described as a wilderness species requiring large tracts of undisturbed habitat. However, in today’s world, most grizzly bears live in close proximity to humans (Schwartz et al. 2003). Even in Yellowstone National Park, the impacts of humans can affect the long-term survival of bears (Gunther et al. 2002). As a consequence, the park has long supported grizzly bear research in an effort to understand these impacts. Most people are familiar with what...

Mountain ecosystems within our national parks and other protected areas provide valuable goods and services such as clean water, biodiversity conservation, and recreational opportunities, but their potential responses to expected climatic changes are inadequately understood. The Western Mountain Initiative (WMI) is a collaboration of scientists whose research focuses on understanding and predicting responses of western mountain ecosystems to climatic variability and change. It is a legacy of the Global Change Research Program initiated by the National Park Service (NPS) in 1991 and continued by the U.S. Geological Survey (USGS) to this day as part of the U.S. Climate Change Science Program (http://www.climatescience.gov/)....

During the 2012 field season, the Central Alaska Network (CAKN) Stream Monitoring Program made 130 site visits to 58 unique stream sites across the network (Figure 1), with each site being sampled one to five times from early May through late September. The data collected included instantaneous water chemistry, stream flow, water chemistry samples, macroinvertebrates, benthic diatoms, stable isotope samples, habitat data and environmental DNA samples. Continuous year-round temperature monitoring at 23 sites across the network is ongoing. At the request of DENA staff, the Stream Monitoring Program collected water chemistry, metals, invertebrates and diatoms from 7 sites in the Kantishna Hills. Active layer depth...

High resolution vegetation polygons mapped by the National Park Service. A total of 800 acres (324 ha) were mapped. Thirteen map classes were used to describe the landscape. Among these were six plant association, one alliance, two non-natural map classes (Disturbed, Development), three local types, and one un-vegetated natural class (Open Water).

From March 21, 2010 to March 24, 2010, a winter marine bird and mammal skiff-based survey along the coast of Kenai Fjords National Park (KEFJ) was completed. This was the second winter survey completed for KEFJ since 2008. The primary objectives of the SWAN winter surveys are to characterize the species composition, density and distribution of the overwintering marine ducks prior to their migration to breeding grounds. Seasonal differences in species composition, distribution and density of other marine birds and mammals are also documented. The overall design calls for the sampling of the same transects during both the winter and summer surveys if safe and appropriate conditions allow. The 2010 survey took approximately...

The GRBA draft General Management Plan proposes development in several locations in Kious Spring and Lehman Caves 1:24,000 topographic quadrangles, and these proposed developments need geologic evaluation before construction. Brown will act as project manager to coordinate the IA with time frames, budget constraints, and the timely preparation of required maps, reports, and GIS data sets. In addition to having been an interpretive Ranger-Naturalist in two National Parks, Brown has published USGS interpretive geologic maps and USGS bulletins. Her research includes sedimentologic, stratigraphic, and structural analyses of Laramide intermontane basins in the Westem Interior.

This report describes the work performed by the Alaska Exotic Plant Management Team at Yukon-Charley Rivers National Preserve and Gates of the Arctic National Park & Preserve during the 2011 season including objectives, methods, and major conclusions. This field work is a continuation of work done by the Alaska Exotic Plant Management Team in the summer of 2010. The 2011 season was divided into four main regions from highest to lowest priority: Coal Creek Camp; Slaven’s Roadhouse; the Dalton Highway south of Coldfoot, AK; and Gates of the Arctic National Park & Preserve along the Middle Fork of the Koyukuk River. The main area of focus during the 2011 season was the high traffic areas along Coal Creek; a tributary...

The National Park Service (NPS) manages the nation's most iconic destinations that attract millions of visitors from across the nation and around the world. Trip-related spending by NPS visitors generates and supports a considerable amount of economic activity within park gateway communities. This economic effects analysis measures how NPS visitor spending cycles through local economies, generating business sales and supporting jobs and income. In 2012, the National Park System received over 282 million recreation visits. NPS visitors spent $14.7 billion in local gateway regions (defined as communities within 60 miles of a park). The contribution of this spending to the national economy was 243 thousand jobs, $9.3...

Haleakalā National Park (HALE) was surveyed for landbirds and habitat characteristics from March 20 through July 26, 2012. This information provides data in the time-series of landbird monitoring for long-term trends in forest bird distribution, density, and abundance. The Kīpahulu District of eastern Haleakalā Volcano was surveyed using point-transect distance sampling to estimate bird abundance. We surveyed 160 stations and detected a total of 2,830 birds from 12 species. Half of the species were native and half were non-native. Numbers of detections per species ranged from 1 to 849. There were sufficient detections of seven species to allow density estimation. Āpapane (Himatione sanguinea) was the most widely...

An August 2004, north-looking photograph, taken by Ron Karpilo, National Park Service, showing a retreating unnamed valley glacier that forms the East Fork of the Teklanika River, Denali National Park and Preserve, Alaska. The photograph shows the retreating, debris-covered terminus of East Fork Teklanika Glacier with an elevated lateral moraine on its west (left) side. Compare with a 1906 photograph from the same location by S.R. Capps. Note: Link to S.R. Capps photograph number 917 is under Web Links below.
