Caribou (Rangifer tarandus) are an integral part of the ecological and cultural fabric of northwest Alaska. Western Arctic Herd (WAH) caribou roam over this entire region, including all 5 Arctic Network Inventory and Monitoring Program (ARCN) National Park Units. Conservation of healthy caribou populations are specifically mentioned within the enabling legislation (Alaska National Interested Lands Conservation Act or ANILCA) of three of these Parks and is of critical concern to subsistence hunters within this region. Caribou are, by far, the most abundant large mammal in northwest Alaska and are famous for their long-distance migrations and large population oscillations. For these reasons, ARCN chose WAH caribou...

This document summarized the effort to derive new map data using reclassification logic or rule-based aggregation processes for WRST. The final map data set retains this highly detailed “bird’s-eye view” level of information in the form of a land cover database. Generalized land cover maps may then be derived from this detailed land cover database. In addition, alternative more directed detailed maps may be derived from the land cover database as needed.

Passerine birds (passerines) in Denali National Park and Preserve (Denali) have been selected for long-term monitoring as part of the National Park Service's (NPS) Inventory and Monitoring Program. Monitoring goals include relating bird distributions to habitat characteristics and detecting severe population declines over 20 years. Point transect surveys were implemented to monitor breeding passerines because distance sampling methods adjust counts for probability of detection, require only 1 visit to each sampling point during a breeding season, and allow monitoring of multiple species because males are easily identified by their songs. Our objectives were to analyze pilot data to 1) assess adherence to assumptions...

This report describes the work performed by the Alaska Exotic Plant Management Team at Denali National Park & Preserve during the 2011 field season. The 2011 Exotic Plant Management Team at Denali National Park & Preserve comprised of two Student Conservation Association interns including one International SCA from Japan and one National Park Service employee. For the eighth consecutive year invasive plant inventory and control efforts were performed within the park. Efforts were focused on disturbed areas with high traffic use which consist of park entrance trails, park infrastructures, and areas along the Park Road corridor. Infestations of invasive plants were mapped using a Trimble 2005 GeoXT, and controlled...

This report describes the work performed by the Alaska Exotic Plant Management Team at Yukon-Charley Rivers National Preserve during the 2010 season. The 2010 field season was the first year of an organized weed program in Yukon-Charley Rivers National Preserve with two Student Conservation Association interns stationed at the preserve for the entire summer. Both staff members were hired with American Recovery and Reinvestment Act funding. Prior to 2010 Yukon-Charley Rivers National Preserve staff surveyed for invasive plants in the preserve with some assistance from the Alaska Exotic Plant Management Team. Limited treatments were performed and little data exists to describe the type or density of species previously...

This report summarizes the 2006 climate year for the Central Alaska Inventory and Monitoring Network (CAKN). It includes a sysnthesis and analysis of temperature and precipitation from a network of weather stations in and around the three CAKN parks which include Denali National Park and Preserve, Wrangell - St. Elias National Park and Preserve, and Yukon - Charley Rivers National Preserve.

We used the CRU (1950-1959 and 2000-2009) and projected 5-GCM composite (2001-2010, 2051-2060, and 2091-2100) decadal climate forcing, ecotype (Stevens 2001), soil landscape (Clark and Duffy 2006), and snow (unpublished) maps of DENA to model the presence or absence of near-surface permafrost, temperature at the bottom of seasonal freeze-thaw layer and its thickness within DENA. We produced permafrost temperature, and active-layer and seasonally-frozen-layer thickness distribution maps through this modeling effort at a pixel spacing of 28 m. This is an immense improvement over the spatial resolution of existing permafrost maps on any part of Alaska, whether produced through the spatially explicit thermal modeling...

This report details the inventory of the mammals at 10 general localities in the Yukon-Charley Rivers National Preserve (YUCH, the Preserve), upper Yukon River region, Alaska, in July and August 2001. We begin the process of documenting the approximately 40 species of mammals that occur in YUCH with a primary focus on small mammals (the shrews, voles, lemmings, mice, weasels, porcupine, squirrels, pika and hare).
