This dataset represents the soil temperature regimes from SSURGO and STATSGO soil descriptions for soil map units in the state of southern Alaska (b) that lie within the North Pacific Landscape Conservation Cooperative. Definition.—“Soil temperature” is the mean monthly soil temperature at the specified depth (the average of the daily high and daily low temperature for the month). Significance.—Soil temperature is important to many biological and physical processes that occur in the soil. Plant germination and growth are closely related to soil temperature. Cold soil temperatures effectively create a thermal pan in the soil. Roots cannot uptake moisture or nutrients below the threshold temperatures specific to...

This dataset represents the soil water storage capacity (AWS in mm at 0.25 m depth) from SSURGO and STATSGO soil descriptions for soil map units in the state of southern Alaska that lie within the North Pacific Landscape Conservation Cooperative. Available Water Storage 0-25 cm - Weighted Average (centimeters). Available water storage (AWS). The volume of water that the soil, to a depth of 25 centimeters, can store that is available to plants. It is reported as the weighted average of all components in the map unit, and is expressed as centimeters of water. AWS is calculated from AWC (available water capacity) which is commonly estimated as the difference between the water contents at 1/10 or 1/3 bar (field capacity)...

Mortalities of Florida manatees (Trichechus manatus latirostris) have significantly increased this winter, especially along the East Coast of Florida, leading to the declaration of an Unusual Mortality Event (UME). Carcasses are exhibiting signs of starvation, related to a lack of food resources from persistent algal blooms and cold stress. These conditions are expected to continue through at least next winter. We will perform health assessments with our partners and attach GPS telemetry tags for current information on habitat use. We will perform habitat surveys at sites used by manatees, determine available species composition and extent, and collect data to inform carrying capacity estimation. Specific objectives...

Hawaiʻi is considered a worldwide biodiversity hotspot, with nearly 90 percent of its native plants found nowhere else in the world. However, about half of these native plants are imperiled by threats including human development, non-native species, and climate change. Through this project, scientists modeled the relative vulnerability of over 1,000 native plant species to the effects of climate change. A panel of experts in Hawaiian plant species assisted with the development of the model and verified its results. From the model, researchers were able to develop a vulnerability score for each plant species and identify categories of species with high, medium, and low vulnerability to climate change. This information...

Native grasslands have been reduced to a fraction of their original extent, with estimated total loss prior to the 1990s of 70% for prairie grassland (Federal Provincial and Territorial Governments of Canada 2010). Conversion of native grassland to cropland and tame hayfields or pasture has been one of the leading drivers of native grassland loss in North America. Degradation of native grasslands also continues in some areas due to changes in natural disturbance regimes such as fire suppression and intensive prolonged cattle grazing, threats from invasive non-native species, fragmentation, intensification of agriculture, and economic development associated with population growth(Federal Provincial and Territorial...

This carbon sequestration research is part of a new pilot grassland conservation program to protect at-risk grasslands from conversion to cropland in the northern Great Plains. Natural resources partners have leveraged more than $3 million in private and federal funding to support an innovative program that extends protection of privately-owned grasslands that have expired under the Conservation Reserve Program (CRP). In the past two years alone, the number of CRP acres nationally has dropped from 31.2 million to 27 million. Of the 4.2-million-acre-decline, lands lost in North Dakota and Montana accounted for 1.6 million acres, or 38 percent. The program aims to encourage private landowners to conserve CRP grasslands...

Contributing to a core component of the Nature’s Network, the Western Pennsylvania Conservancy conducted an analysis on species-habitat associations data to develop a measure of overall species importance, summarized across all species, for each habitat class in the Northeast. This project extended the Habitat Associations project, in which the North Atlantic Landscape Conservation Cooperative partnered with NatureServe to produce a tabular dataset linking set of terrestrial and aquatic habitat layers with NatureServe element occurrence data for over 600 species of greatest conservation concern identified by states in FWS Region 5. Results data from the analysis were delivered in tabular format and joined to the...
We propose to support the revision and implementation of the South Atlantic Landscape Conservation Cooperative’s Conservation Blueprint by integrating its Ecosystem Indicators into a structured decision support system that makes explicit how the Indicators are interrelated and how these will respond to management and policy interventions aimed at improving the conservation status of the South Atlantic region. Our specific objectives are to (1) develop ecological production functions that predict theecological impacts of selected conservation actions relative to current conditions, and to propagate these impacts through other affected systems or functions; (2) codify protocols for updating and curating geospatial...
We will develop SMART-SLEUTH, an advanced spatially explicit modeling framework designed to augment the current SLEUTH model with sophisticated smart-growth capabilities. Based on the latest version of SLEUTH, we will create an open-source GIS-enabled software package that will implement SMART-SLEUTH with advanced modules and tools for evaluating, predicting, and visualizing smart growth scenarios and outcomes. In this software package, a more user friendly Graphic User Interface (GUI), a multi-level automatic calibration approach built on machine learning algorithms, and new spatial landscape metrics for quantifying land change patterns will provide enhanced support for complex model configuration, calibration,...
The Nature Conservancy (TNC) recently completed an unprecedented assessment of almost 14,000 dams in the Northeastern United States. The Northeast Aquatic Connectivity (NAC) project allows fisheries managers and other interested parties to assess dams at multiple scales based on their potential to benefit anadromous and resident fish species if removed or bypassed. This work has continued, with support from NOAA and USFWS, in the Chesapeake Bay watershed, where data refinements and further analysis have produced a web map and tool that allow users to interactively prioritize dams for mitigation at multiple scales and with varying criteria.The Southeast Aquatic Resources Partnership (SARP) has recently completed...

Rate of global biodiversity loss increased significantly during the 20th century associated with human environmental alterations. Specifically, mismanagement of freshwater resources contributed to historical and contemporary loss of stream-dwelling fish diversity and will likely play a role in determining the persistence of species in the future. We present a mechanistic pathway by which human alteration of streams has caused the decline of a unique reproductive guild of Great Plains stream-dwelling fishes, and suggest how future climate change might exacerbate these declines. Stream fragmentation related to impoundments, diversion dams and stream dewatering are consequences of increasing demand for freshwater resources...

We propose to use long-term fish-population data from a relict reach of the Pecos River, New Mexico to assess population dynamics of imperiled prairie-river minnows, including Arkansas River shiner. Development of viable management strategies requires basic understanding of population ecology. Rigorous, quantitative ecological methods can be used to analyze continuous, long-term demographic data, but such data are rarely available for imperiled, non-game fishes. Data available for the Pecos River provide a unique opportunity to apply quantitative methods to prairie-river minnow conservation and management. Analyses proposed here would determine (1) whether population regulation is density dependent or flow-regime...

The tillage suitability product is a per-crop, per-pixel (30 square-meters) model representation of the predicted probability (0.00-1.00) that an area can support commodity crop development for a suite of crop types commonly grown in the LCD landscape. The values for each grid cell are interpreted as a probability, with any value greater-than 0.50 suggesting an area should be suitable for crop development based on observations of 2.5 million farmed areas around the LCD geography. To demonstrate composite suitability (“tillage”) for all crops, we added the individual probabilities for our modeled from cover classes (cereals, corn, cotton, and beans), which represents the overall proportion of votes for “crop” vs....

These data represent areas defined as large block grasslands according to a model developed by PLJV (McLachlan 2008). The model is based on literature derived Lesser Prairie-Chicken habitat preferences and considers habitat composition within a 2,000 ha area. Any pixel with more than 58% grass, less than 36% cropland, less than 2% woodland/ shrubland, less than 5 % secondary roads, and no 4 lane roads within a 2,000 ha surrounding area is counted as a large block grassland pixel.
