Conclusions: Habitat associations of prairie rattlesnakes appear to differ depending on whether snakes are hibernating, foraging, or reproducing. Most rattlesnake hibernacula occur within 4 km of a major river, drainage, or coulee, on relatively gentle slopes, but they migrate as far as 25 km away from dens in summer. High road densities present unfavorable habitat conditions for snakes because they are a significant cause of mortality. *Note that this study generated landscape level models with coarse variables, and the thresholds and values used may not be directly applicable to other areas or for site-specific analysis. Thresholds: Most rattlesnake hibernacula occur within 4 km of a major river, drainage, or...

Conclusions: Although there was not a detectable decrease in bird communitiy species richness resulting from experimental forest fragmentation, community structure was altered, and maintaining connections between fragments significantly mitigated these effects. Thresholds/Learnings: Synopsis: This study examined the effects of forest fragmentation on the richness, diversity, turnover, and abundance of breeding bird communities in old boreal mixed-wood forest by creating experimental forest fragments of 1, 10, 40, and 100 ha. Connected fragments were linked by 100 m wide buffer strips. The study detected no significant change in species richness as a result of forest harvesting, except in the 1 ha connected fragments...

Synopsis: This study monitored the response of a species of pine bark beetle, Trypodendron lineatum, to direct and indirect measures of habitat availability in a forest subjected to various levels of harvest intensities. Four stand types (conifer dominated, mixed, deciduous dominated, and deciduous dominated with conifer understory) were treated with four levels of harvest intensity (unharvested, 50%, 80%, and 90% harvested). Prior to harvest, the pine bark beetle was most abundant in stands with many host trees (conifer dominated stands). In the first and second summers after harvest, pine beetle abundance increased exponentially with percent spruce cover and the number of spruce stumps in the stand. Beetles were...

Conclusions: Results offer support for the use of land cover as an indicator of biotic integrity estimated by both vegetation and bird communities. Strong, significant predictions of IBI scores in plant and bird communities were achieved using land cover data from every spatial extent. Plant-based IBI scores were best predicted using data from 100 m buffers and bird-based IBI scores were best predicted using data extracted from 500 m buffers. Road density and measures of the proportion of disturbed land were consistent predictors of IBI score, suggesting their universal importance to plant and bird communities. Thresholds/Learnings: Road effects on bird communities were most pronounced at the 500m spatial extent....

Synopsis: This model is based around Native Prairie Cover types, and Soil Texture. Native Prairie Class (NPC) is derived from the Native Prairie Vegetation Baseline Inventory developed by AlbertaEnvironment. Class I is comprised of greater than 75% native prairie components (i.e. shrubs, graminoids, riparian areas, lakes, wetlands, and trees), Class 2 is 50 - 75%, Class 3 is 25 - 50%, Class 4 is 1 - 25%, and Class 5 is no native prairie components. Native prairie is probably the most important and limiting factor for ferruginous hawks. Although hawks have been found in areas that were primarily under cultivation), they were in close proximity to prairie in good condition. Overall NPC was selected over its individual...

Conclusions: Areas for roosting are likely the most limiting factor for the Western Small-footed Myotis. Unlike various other bats, this myotis does not roost in trees, but rather under rocks, and in holes and crevices found in rock outcrops within cliffs and coulees. Summer roosts can be found in cavities within cliffs, boulders, vertical banks, the ground, and talus slopes. Distance to water was also a significant factor affecting habitat suitability Thresholds/Learnings: Habitat for western small-footed myotis bats is ideally located within 1000m of water. Habitat located >3000m from water is deemed unsuitable. Synopsis: Areas for roosting are likely the most limiting factor for the Western Small-footed Myotis....

Synopsis: This study evaluated the effects of landscape management on the spread of mountain pine beetle colonization in Banff National Park, Alberta, Canada. Researchers used annual aerial survey data and geo-referenced locations of colonized trees that were cut and removed to assess if the area colonized and the spatial extent of pine beetles differed between monitoring and management zones. Pine beetles were allowed to follow their natural course in the monitoring zone, while an extensive eradication program involving cutting and burning colonized trees was established in the management zone. Management resulted in no detectable effect on the scale of the zone. However, at the sub-zone scale, the area affected...

We propose a regional assessment of aquatic species vulnerabilities and responses to climate change as the basis for adaptive management for aquatic ecosystems in the Great Northern LCC, using the Transboundary Flathead Ecosystem as a case example. This region encompasses a complex mix of federal, state, tribal, and private lands in the US and federal, provincial and private lands in Canada. The complex suite of ownerships, international relations, and agency objectives establish their own set of challenges; however, all will experience a similar range of climatic (e.g., long-term drought and declining snow pack) and non-climatic (e.g., habitat fragmentation, shifting land- and water use patterns, and invasive species)...

LC MAP, the Landscape Conservation Management and Analysis Portal, allows GNLCC partners to discover, use, develop, manage, and distribute datasets that address LCC priority issues. In FY11, this effort will extend LCMAP to allow users to generate dynamic interactive map viewers, modeled output, and web services for use in ArcExplorer and other client tools. In addition, the project will build the LCMAP Phenology Service, adding ESRI image services to the application suite and allowing GIS analysts and modelers access to a full suite of phenology data for use in ArcMap and other client tools.The set of data development and presentation tools planned will allow GIS analysts in the GNLCC community to work with multiple...

Synopsis: Because recent bark beetle population eruptions have exceeded the frequencies, impacts, and ranges documented during the previous 125 years, researchers have been prompted to determine what factors trigger broad scale outbreaks, and how do these factors interact? How do human activities, such as forest management, alter these interactions, and thus the frequency, extent, severity, and synchrony of outbreaks? Extensive host tree abundance and susceptibility, concentrated beetle density, favorable weather, optimal symbiotic associations, and escape from natural enemies must occur jointly for beetles to surpass a series of thresholds and exert widespread disturbance. Eruptions occur when key thresholds are...

Conclusions: In response to logging, songbirds demonstrated “habitat compensation” by moving into different adjacent habitats across a fragmented landscape. Thresholds/Learnings: Synopsis: This study investigates the degree to which species respond differently to logging across different scales in Alberta’s boreal mixed-wood forests. Researchers tracked changes in the composition and abundance of songbirds at the patch-level and landscape level, finding significant variation between the two spatial scales. The results suggest that predictions of organism response based on the island biogeographic model are limited, and that—while responses varied across species—songbirds demonstrated “habitat compensation” by moving...

Conclusions: Soil texture, native prairie and grassland cover, and proximity to linear disturbances affect habitat suitability for burrowing owls. Native prairie coverage was considered the most critical variable in determining the most suitable habitat. The higher the percentage of native prairie, the more suitable it is for burrowing owl habitat.*Note that this study generated landscape level models with coarse variables, and the thresholds and values used may not be directly applicable to other areas or for site-specific analysis. Thresholds/Learnings: Synopsis: This report provides information on the habitat suitability requirements of the burrowing owl. Due to limited available data, the model that this...
