Post-fire regrowth is an important component of carbon dynamics in Canada's boreal forests, yet observations of structural development following fire are lacking across this remote and expansive region. Here, we used Landsat time-series data (1985–2010) to detect high-severity fires in the Boreal Shield West ecozone of Canada, and assessed post-fire structure for > 600 burned patches (> 13,000 ha) using airborne light detection and ranging (lidar) data acquired in 2010. We stratified burned areas into patches of dense (> 50% canopy cover) and open (20–50% canopy cover) forests based on a classification of pre-fire Landsat imagery, and used these patches to establish a 25-year chronosequence of structural development...

These tables serve as input data for hierarchical models investigating interactions between raven density and Greater Sage-grouse nest success. Observations were recorded over an 11 year time period, spanning from 2009 through 2019. The model is run in JAGS via R, the code is publicly available via the U.S. Geological Survey's GitLab (O'Neil et al. 2023). We recommend not making any changes or edits to the tables unless the user is experienced with hierarchical modeling.

Understanding the complexity and ecological organization of protected area ecosystems, and their bioregional surroundings, is fundamental to maintaining their integrity. This research set out to integrate the bodies of systems and hierarchy theory to establish a framework for developing a conceptual model that would synthesize knowledge from diverse fields and identify key system processes, thereby providing new insight into ecosystem organization, function, and integrity. This understanding was then applied to planning for ecological integrity in the Canadian National Parks context through a case study of Kluane National Park and Reserve (KNP&R) within the Greater Kluane Region (GKR). The methodology characterized...

The Museum of Northern Arizona will leverage tools previously developed through its Springs Stewardship Initiative to help resource managers in the southwestern U.S. collect, analyze, report upon, monitor and archive the complex and inter-related information associated with springs and spring-dependent species in the region. Building upon those past efforts, the project will include compilation of existing springs-related information to make the information more readily available online and further development of interactive online maps and climate change risk assessment tools of springs-dependent sensitive plant and animal species. This project builds on an effort funded in FY 2013 to complete similar work for...

Although reliable figures are often missing, considerable detrimental changes due to shrinking glaciers are universally expected for water availability in river systems under the influence of ongoing global climate change. We estimate the contribution potential of seasonally delayed glacier melt water to total water availability in large river systems. We find that the seasonally delayed glacier contribution is largest where rivers enter seasonally arid regions and negligible in the lowlands of river basins governed by monsoon climates. By comparing monthly glacier melt contributions with population densities in different altitude bands within each river basin, we demonstrate that strong human dependence on glacier...

This data layer summarizes ecological systems and land cover classes described in state-level and national-level maps as Broadly Defined Habitats for groups of species of conservation concern. Each grid cell in the raster is assigned a Condition Index value based on desired condition metrics using ancillary datasets and a decision tree approach for each assessed habitat. Grid cells are also assigned bar code descriptors indicating which metrics contributed to the Condition Index score for that cell. This layer also contains information about potential habitats based on the LANDFIRE Biophysical Settings data layer. This layer was developed to support the next iteration of the Conservation Blueprint developed by the...
This thesis is about aboriginal and treaty rights to wildlife and wildlife harvesting, including the right to make decisions about these activities in the Northwest Territories. It deals with the erosion of these rights in the period before 1982 and then traces the protection, redefinition and resurgence of these rights since 1982, when section 35 of the Constitution Act, 1982 was enacted. Section 35 affords constitutional protection to treaty and aboriginal rights including those rights negotiated through modern land claim agreements. This thesis shows that the effect of section 35 jurisprudence and land claims has been to halt the erosion of aboriginal and treaty rights to wildlife and to enhance local control...
