Forest- Data collected once using GIS prior to fish sampling. Our approach was to focus the study on smaller, headwater catchments because larger streams drained areas containing both hemlock and mixed hardwood forest, making forest-specific comparison intractable. In addition, most of these larger watersheds were impacted by humans (e.g., impoundments, agriculture, quarries) that could confound our assessment of the influence of hemlock. Even after limiting the study to headwater catchments, other possible confounding factors remained; we controlled for landscape variability (i.e., terrain and stream size) through the sampling design and we excluded others (i.e., minimum catchment area,beaver activity) through...

Raw data were collected in Shenandoah National Park during summer 2012. Air and temperature data were collected using temperature loggers at several stations throughout the park. These data were used in the publication of the manuscript "Accounting for groundwater influence on headwater stream thermal sensitivity to climate change" through the journal Ecological Applications. Water temperature data were collected at all 78 reach locations during the summer of 2012 (23 June–7 September). Temperature was measured every hour with a logger.

The data set includes delineation of sampling strata for the six study reaches of the UMRR Program’s LTRM element. Separate strata coverages exist for each of the three monitoring components (fish, vegetation, and water quality) to meet the differing sampling needs among components. Generally, the sampling strata consist of main channel, side channel, backwater, and impounded areas. The fish component further delineates a “shoreline” portion of the strata to be used for sampling gears deployed only along the shoreline. The data are raster in origin, with the center of each pixel representing the sampling location. Cell size is typically 50 meters, although several water quality strata are at 200 meter cell size.
This data set was created to facilitate the BLM Greater Sage-Grouse Land Use Planning Strategy in the Utah Sub-Region. This data was developed and addressed, and used during preparation of an environmental impact statement to consider amendments to 14 BLM land use plans throughout the State of Utah, as well as 6 Forest Service land use plans. This planning process was initiated through issuance of a Notice of Intent published on December 6, 2011. This dataset is associated with the Final Environmental Impact Statement, released to the public via a Notice of Availability on May 29, 2015. The purpose of the planning process is to address protection of greater sage-grouse, in partial response to a March 2010 decision...

Political ecology is a holistic mode of inquiry that applies political analysis to resource use and access by actors and organizations interacting in defined social and cultural contexts. This thesis uses a political ecology perspective to reveal how the Atna' Athabaskan people of South central Alaska use their knowledge of their environment to articulate a specific claim to Copper River salmon. Three case studies of Atna' public activism are presented demonstrating Atna' practice in governmental regulatory process. The position of the Atna' in the Copper River salmon fishery is contrasted with three other north Pacific Native American salmon regimes in order to demonstrate the special features of the Atna' context.

This article reviews social science research on Indigenous wildfire management in Australia, Canada and the United States after the year 2000 and explores future research needs in the field. In these three countries, social science research exploring contemporary Indigenous wildfire management has been limited although there have been interesting findings about how Indigenous culture and knowledge influences fire management. Research with Indigenous communities may be limited not because of a lack of interest by social scientists, but rather by obstacles to doing research with Indigenous communities, such as ethical and time concerns. Research needs on Indigenous wildfire management are presented, centred on the...

Harbor porpoise, Phocoena phocoena vomerina, in Cook Inlet, Alaska, are managed as part of the Gulf ofAlaska (GOA) stock. It is not known if this population is distinct from porpoise in the GOA stock found outside Cook Inlet. No long- term dedicated studies of harbor porpoise have occurred in Cook In let. The objective here is to provide a summary of occurrence in Cook Inlet derived from archaeological data, anecdotal reports, and systematic surveys. Maps were created for each dataset. Therefore, each of these estimates is likely biased downward. In the last decade the region has seen expansion of the Port of Anchorage, proposals to build a bridge crossing Knik Arm, plans to develop mining operations and supporting...

Nine native taxa including Carex oligosperma, C. pauciflora, C. pellita, Chimaphila umbellata ssp. occidentalis, Draba densifolia, x Elyleymus hirtiflorus, Eriophorum vaginatum ssp. spissum, Impatiens ? capensis, and Rhus radicans are reported new to the known flora of the Yukon Territory. Eight introduced taxa are also reported as new to the known flora. Significant range extensions within the Territory are reported for 180 native and 17 introduced taxa. Comments are presented on three native taxa and two native taxa are deleted from the Territory.
