USFWS, Region 8, Reno, Nevada desired to acquire LIDAR along the East and West forks of the Walker River, Nevada. Their goal is develop an accurate digital elevation model (DEM) within the river channel and into the uplands approximately 500 meters on each side. The goal is to use the DEM to assist in targeting restoration efforts for Lahonton Cutthroat as well as characterize the riparian vegetation and associated nearby uplands. [see Narratives for more information.]

Waterbirds breeding at wetlands in North Dakota forage mostly on aquatic invertebrates. Historically, productivity and abundance of aquatic invertebrates primarily was driven by inter-annual hydrological dynamics (i.e., wet-dry cycles). Wetland drying allows for nutrient cycling and a subsequent pulse of productivity when wet conditions return. However, abundance and quality of wetlands in North Dakota has declined due to landscape modifications, primarily agriculture. Consolidation drainage, a practice of draining less permanent wetlands into larger more permanent ones, is common in North Dakota and it increases connectivity and stabilizes water levels among remaining wetlands. For the effective management and...
In the Prairie Pothole Region (PPR) wetland plant, invertebrate, and waterbird productivity are primarily driven by water-level dynamics in response to climate cycles. Large proportions of wetlands in the PPR have been drained, often consolidating water from smaller to larger-interconnected wetlands. This project will examine whether large basins that receive inflow from consolidation drainage have reduced water-level dynamics in response to climate cycles than those in undrained landscapes, resulting in relatively stable wetlands that have lower densities of invertebrate forage for ducks and shorebirds. We will also include a sample of wetland historically used by piping plovers to assess the threat of consolidation...

Many studies have demonstrated the utility of developing species occurrences models, particularly breeding bird occurrences in forested landscapes, at the forest stand level. The success of these models often require forest stand structural metrics, in addition to metrics acquired in the surrounding landscape, for predicting species occurrences. While it is feasible to statistically estimate “how much” of this particular habitat structure at the stand level there is across the landscape through appropriate sampling schemes, in general, these estimates are not spatially explicit (e.g. what is the structure in the stand next to the one sampled, and then in the one next to that, etc.?). Remote sensing technologies,...

Our team will estimate the effects of anthropogenic land use modification on the distributions of grassland birds in the Prairie Pothole Region (PPR), USA. The models we develop will improve understanding of how local land use decisions impacts grassland bird populations. Our models will allow stakeholders to estimate how the diversity of grassland birds changes across a landscape with varying land use practices. Our study will focus on grassland bird species with varying conservation needs and include areas of the PPR that have a broad spectrum of land use conditions. We will utilize modern Bayesian techniques to develop species distribution models that fully integrate environmental data layers and species distribution...
Camp Ripley, in north-central Minnesota, is a large state-owned National Guard training facility that supports military and civilian training. Training consists of maneuvering troops and equipment as well as weapons familiarization and qualification, including aviation and armor gunnery. The civilian training mission focuses primarily on law enforcement and emergency management activities as well as natural resource education. Much of the training can cause disturbances to the natural resources within and around the Camp. The central mission of the natural resources management program at Camp Ripley is to ensure that the multiple demands for land use can be met without sacrificing the integrity of the resources...

Private and public holders of forest lands make daily decisions concerning management of their respective tracts with little understanding about the consequences to wildlife both on and adjacent to surrounding tracts of land. ECOSEARCH Version 1 (Short et al. 2001) is a computer program containing species-habitat models that provide a scientific basis for predicting the outcome of alternative management actions on wildlife within forested landscapes. Hence, ECOSEARCH is a tool that allows managers of forests to better balance the often-conflicting demands of economics and conservation. ECOSEARCH also provides a means by which small and large land holders can link their management goals and objectives with those...

Sagebrush steppe refers to the intermountain basins west of the Great Plains that are characterized by vegetation communities that include sagebrush and associated plant species that are also found in grasslands. Sagebrush-steppe habitats have experienced dramatic changes since European settlement. Today, this ecosystem is considered imperiled, having decreased by about 50 percent in Western North America, and currently is undergoing intense fragmentation and degradation. As a result, sagebrush-steppe dependent species have experienced drastic range contractions and population declines; one notable example being the Sage-Grouse (Centrocercus spp). Sage-Grouse populations have declined by 15–90% since the early 1970s,...
