Update of the Eastern Gulf Coastal Plains and Ozarks Land Cover Database to 2011 Using a LS2SRC Classification Approach
Concurrent with the geographic expansion of the Southeast GAP land cover mapping will be a change detection effort that will provide updated land cover for portions of the Gulf Coastal Plains and Ozarks geography previously mapped based on 2001 imagery.
Presentation: Using narrative stories to understand Traditional Ecological Knowledge in the Great Basin
This presentation aired as part of the Great Basin LCC webinar series on December 6, 2017. The presentation was given by Dr. Tamara Wall of the Desert Research InstituteOne of the challenges facing public land managers in the Great Basin is identifying adaptation strategies to increase resiliency to climate change in an area that is already struggling with profound environmental challenges. Recent efforts to understand how the Great Basin weathered past droughts and climate variability may offer insight into approaches that could work in future decades. One approach to gather this information is to understand Traditional Knowledge. Gathering this information is challenging and requires an acknowledgment that much...
The GCPO LCC region contains some of the most diverse aquatic biota in the world. The streams and rivers on which this biota depends are valuable conservation and economic resources. However, fragmentation of streams and rivers by dams and other barriers is a primary threat to the health of resident and anadromous fish species in southern rivers. Conservation planning in the region requires an assessment of the degree of fragmentation of streams and rivers and potential impacts on fish populations. However, the ability to conduct a connectivity assessment is limited in the GCPO LCC region due to the lack of a comprehensive dataset of fish barrier locations, attributes, and links to basic river maps. SARP proposes...
Assessment of Water Availability and Streamflow Characteristics in the Gulf Coastal Plains and Ozarks Landscape Conservation Cooperative for Current and Future Climate and Landscape Conditions
This research will (1) develop a multi-model application to simulate streamflow using a monthly water balance model and daily time step hydrologic models (physical-process based and statistical) for all watersheds of the Gulf Coastal Plains and Ozarks Landscape Conservation Cooperative and (2) provide products from these models (flow characteristics - magnitude, timing, duration, rate of change, and frequency) for a range of configurations (current and future climate and landscape) through a web interface which can be used to inform management decisions.
Report: Long-Term Trends in Sage-Grouse Demography and Habitats on the Sheldon–Hart Mountain National Wildlife Refuge Complex and Adjacent Blm Lands: an Opportunity to Assess Impacts of Feral Horses and Regional Habitat Connectivity
Populations of Greater Sage-grouse have declined across the entire range of the species and habitat loss is considered to be the most important factor contributing to these declines (e.g., Connelly et al. 2004). Agricultural conversion, energy development, feral horses, and livestock grazing are hypothesized to contribute to habitat related threats (Range wide interagency sage grouse conservation team 2012). Substantial research has been completed to assess the effects of energy development (e.g., Walker et al. 2007) and agricultural conversion (e.g., Aldridge et al. 2008), yet, little research has been devoted to understanding the impacts of grazing by feral horses and livestock on sage-grouse demography.The Sheldon-Hart...
Ecological Assessment-Phase 2: Terrestrial - Developing a Strategic Decision Framework for Terrestrial Species Conservation
Pilot an approach that integrates dynamic landscape population viability models and structured decision making to choose among conservation scenarios that best meet desired endpoints for focal wildlife species. Our combined approach will Identify 3-4 species for each inland terrestrial habitat system listed in the Integrated Science Agenda (15-20 total). Using the combined approach, we will identify potential conservation strategy alternaties intended to meet desired endpoints for focal wildlife species in the Gulf Coastal Plains & Ozarks region under land use change. Scenarios will likely be habitat based, but could include other approaches (e.g. policy).
Report to be added soon.
Webinar: Assessment of the effects of non-native ungulate grazing on Greater Sage-grouse and their habitats
This presentation aired as part of the Great Basin LCC webinar series on November 1, 2017. The presentation was given by Dr. Jim Sedinger and Phillip Street of University of Nevada Reno and Shawn Espinosa of the Nevada Department of Wildlife.Description: This project uses management-related variation in grazing by both feral horses and livestock as well as five years of field work to assess how both Greater Sage-grouse and the habitats on which they depend might be influenced by grazing. The research team monitored radio-tagged sage-grouse and vegetation on Hart Mountain and Sheldon National Wildlife Refuges as well as lands managed by the Bureau of Land Management (BLM) south and west of Sheldon from 2013-2016....
Ecological Assessment Phase 2: Aquatic - Multi-objective Conservation Planning: Prototyping a strategic decision framework for aquatic species conservation
Long-term, large-scale (i.e. landscape) conservation struggles with big questions such as how can a single strategy be identified when there are multiple possible future outcomes? How do we decide which management action or portfolio of actions is the best for all species when different species will likely have conflicting responses to each action? Successful natural resource decision making processes also incorporate an assessment of baseline conditions; current and future stressors; a set of potential management actions; and formal linkages between conditions, actions and biological responses (i.e. a model). It also requires bringing together the elements of conservation decisions into a framework that allows...
