A bare earth Digital Elevation Model (DEM) created from 2011 LiDAR LAS files for Austin and Colorado counties in Texas. LiDAR data collection was funded by the Texas Water Development Board. LiDAR LAS files were acquired from Texas Natural Resources Information System (TNRIS). The DEM is a dataset that depicts the topography of the bare earth surface (i.e. surface minus vegetation, buildings, powerlines, etc). This dataset was developled to be used in conjunction with the DSM to create a vegetation height surface (nDSM). The LAS point cloud was filtered to ground points only and the mean z value was calculated. A Digital Surface Model (DSM) created from 2011 LiDAR LAS files for Austin and Colorado counties in Texas....

Satellite imagery from the Landsat 5 Thematic Mapper sensor and the Landsat 8 Operational Land Imagery were used to investigate changes in overall evergreen vegetation occurring between the 1986-1989 and 2013-2014 time periods. Two path/rows of imagery, from the spring, summer, and fall seasons for each time period were mosaicked together. The imagery was then subset to remove the presence of clouds from the datasets. Images were further subset using the impervious data from the 2011 version of the National Land Cover Database. Unsupervised classification was used to spate each time period imageinto two classes, evergreen vegetation and everything else. Each subsequent time period was subjected to successive unsupervised...

Grassland conservation is a priority within the GCP LCC. We held a series of meetings and conference calls with partners to identify areas of need both conceptually and geographically. Based on the meeting outcomes, we identified specific tasks that could be accomplished within our scope, including development of datasets and demonstration of a freely available decision support software tool (DST): NatureServe Vista. We generated more than 30 new datasets and posted more than 35 datasets on the GCP LCC Conservation Planning Atlas (CPA). Data were provided for three geographic regions that corresponded to the areas of interest of different partners: the entire LCC, Oklahoma only, and two, 2-county areas in the Coastal...

Gulf Coast Prairie Landscape Conservation Cooperative partners need new computer models to help address threats to grassland habitats, such as land conversion and habitat fragmentation, affecting LCC focal species such as the northern bobwhite and eastern meadowlark. These tools will help partners determine the best places to invest limited resources in conserving and restoring grasslands to support self-sustaining wildlife populations.

The Gulf Coast Prairie Landscape Conservation Cooperative (GCPLCC) has identified grassland habitats and species as priorities for conservation. The goal of the current effort is to (1) identify landscapes of importance at appropriate scale for further work, (2) develop GIS data and decisions support tools to facilitate further conservation efforts. MoRAP identified and mapped grassland landscapes based on neighborhood analysis of current land cover. This dataset includes urban, cropland, and ruderal land cover in order to attribute grassland patches with landscape context variables that may disturb grassland.

Based on discussions with the Grassland Decision Support Tool Technical Review Team, NatureServe,and MoRAP regarding combining efforts for an expanded project to address grassland conservation within the Gulf Coast Prairie LCC, we propose 5 tasks. The effort will utilize the expertise of Nature Serve to facilitate, coordinate and communicate the efforts with stakeholders, and MoRAP to focus on the technical elements of the products identified by partners including data development and analysis. MoRAP performed a spatial analysis to identify opportunities for grassland habitat conservation and attributed these polygons with ecological character / biological variables such as patch size, prevailing potential grassland...
