The Central Alaska Network (CAKN) and the Arctic Network (ARCN) are part of the National Park Service (NPS) Inventory and Monitoring (I&M) Program. CAKN is composed of three national park units: Wrangell-St. Elias National Park and Preserve, Denali National Park and Preserve, and Yukon-Charley Rivers National Preserve. ARCN is composed of Gates of the Arctic National Park and Preserve, Noatak National Preserve, Kobuk Valley National Park, Cape Krusenstern National Monument and Bering Land Bridge National Preserve. The Inventory and Monitoring Program is the result of the National Parks Omnibus Management Act, which was passed by Congress in 1998. This Act directs the National Park Service to ?establish baseline...

This report describes the work performed by the Exotic Plant Management Team (EPMT) at Wrangell-St. Elias National Park and Preserve (WRST) during the 2009 season. Four EPMT members were stationed at three locations in the park: Copper Center, Slana, and McCarthy-Kennecott. Invasive plant inventories and weeding occurred around these three locations, along the McCarthy and Nabesna Roads, along the Copper River, at other locations in the Copper Basin, and at seven backcountry destinations within the park. Invasive plant populations were mapped using GeoXT Trimble units and manual weeding was performed with the help of volunteers, a Southeast Alaska Guidance Association (SAGA) crew, and seasonal National Park Service...
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 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...
This report presents the results of anecological land survey (ELS) effort that inventoried, and classified ecosystems in the Wrangell-St. Elias National Park and Preserve. By analyzing the dynamic physical processes associated with coastal, riverine, lowland, glacial, hillside and mountainous environments, and the abundance and distribution of their diverse ecological resources, this study contributes to ecosystem management in national parklands in Alaska.
This report documents the technical aspects of image processing information for the generation of the Katmai National Park and Preserve land cover map.

Executive Summary: Wolf populations have been monitored in Yukon-Charley Rivers National Preserve (YUCH) from March 1993 to present. Beginning October 2005 the project was incorporated into Central Alaska Network (CAKN) Vital signs monitoring program as a cost shared venture. Wolves throughout Yukon-Charley Rivers area are targeted for monitoring of abundance and distribution. All monitored packs routinely travel outside the Preserve, some extensively. This past winter, wolf captures were conducted in November 2011 and March 2012. Monitoring radio collared packs via radio telemetry flights will occur throughout the year with a concentrated period of flights in March – April and again in September – October. All...

This is the third progress report for a multi-year study of glaciers in Alaskan national parks. The project will be completed in December 2013. Here we present results from mapping of all glacier extents in Gates of the Arctic National Park & Preserve (NP&P), Klondike Gold Rush National Historic Park (NHP), and Aniakchak National Monument & Preserve (NM&P), from measurements of surface elevation changes in Denali NP&P, and from focus glacier research in Denali NP&P, Katmai NP&P, and Lake Clark NP&P. We have accomplished all tasks on schedule for this third deliverable, and we look forward to continued conversation with our colleagues at NPS as the project moves forward. Significant results include the following:...

Intended for timely release of basic data sets and data summaries. An example would be simple, annual reporting of monitoring results. Care has been taken to assure accuracy of raw data values, but a thorough analysis and interpretation of the data has not been completed. Consequently, the initial analyses of data in these reports are provisional and subject to change.
This report describes the results of the 2006 field season for the Central Alaska Network (CAKN) flowing waters monitoring program. The key objectives for the 2006 field season were to assess the logistics involved in various sampling approaches and to collect data from a variety of streams as a way to begin to determine the range of natural variability for various candidate biological, chemical and physical metrics. I was able to collect data at 13 study sites located throughout WRST. Two of these sites were visited in two different seasons (summer and autumn) to assess seasonal variability, which was substantial for invertebrates and diatoms and moderate for water chemistry parameters. At one of these sites, multiple...
This report describes the work performed by the Alaska Exotic Plant Management Team at Wrangell-St. Elias National Park and Preserve during the 2010 season. Six Alaska Exotic Plant Management Team staff members were stationed at Park Headquarters in Copper Center while working at various locations within the park and preserve. Invasive plant inventories and treatments occurred around the following locations: along the McCarthy and Nabesna roads, along the Copper, Chitina, and Nizina rivers, at other locations in the Copper Basin, and at several backcountry destinations within park lands. Invasive plant infestations were mapped using Trimble GeoXT units and manual weeding was performed with the help of volunteers,...

Lakes are dominant and diverse landscapefeatures in the Arctic, but conventional land coverclassification schemes typically map them as a singleuniform class. Here, we present a detailed lake-centricgeospatial database for an Arctic watershed in northernAlaska. We developed a GIS dataset consisting of 4362lakes that provides information on lake morphometry,hydrologic connectivity, surface area dynamics,surrounding terrestrial ecotypes, and other importantconditions describing Arctic lakes. Analyzing thegeospatial database relative to fish and bird survey datashows relations to lake depth and hydrologic connectivity,which are being used to guide research and aid in themanagement of aquatic resources in the NationalPetroleum...
