To display the average annual rates of change of the Texas Coast (shorelines) for the Texas Hazard Mitigation Package (THMP).Local, State, and Federal agencies with coastal management responsibilities currently rely on average rates of shoreline movement and projected future shoreline positions for regulatory purposes. As a result of this dependency on scientific data, regional studies of shoreline movement are now regarded as important sources of information for formulating coastal management policies and long range planning. These coastal investigations now serve as a primary technical basis for decisions made by coastal planners and managers of natural resources located near the shore.

The potential for coordinated planning and evaluation required for integrated bird conservation at the regional or continental scales will be enhanced by a common set of conservation units employed by all bird conservation initiatives. U.S. bird conservationists that met in Puebla and Memphis drafted a set of Bird Conservation Regions (BCRs) by aggregating CEC level II, III, and IV ecoregions in combinations that reflect current understandings of species distribution, life history requirements, and conservation challenges. A total of 36 BCRs cover the North American continent. These regions were established cooperatively for all of the major bird conservation initiatives through the North American Bird Conservation...

The goal of this project is to provide a preliminary overview, at a National scale, the relative susceptibility of the Nation's coast to sea- level rise through the use of a coastal vulnerability index (CVI). This initial classification is based upon the variables geomorphology, regional coastal slope, tide range, wave height, relative sea-level rise and shoreline erosion and accretion rates. The combination of these variables and the association of these variables to each other furnish a broad overview of regions where physical changes are likely to occur due to sea-level rise.

Estimated nitrogen delivered to the estuaries along the Gulf of Mexico (U.S. only). Delivered load is the amount of nitrogen estimated using USGS's SPARROW model to be delivered from the upstream drainage basin to each of the estuaries draining into the Gulf of Mexico. These estimates are corrected to match monitoring load data at the most downstream monitoring site available. Units are in metric tons per year.

At 92.6 million acres, native rangeland continues to be the prevailing general category of land use in Texas. Since 1997, the accumulated localized losses of native rangeland have exceeded 4.8 million acres. In addition the statewide area in dry (non-irrigated) cropland has declined by 1.57 million acres.One of the most notable trends continues to be the conversion of native rangelands and croplands to non-native pastures. Non-native pastures now account for over 11 million acres and are the third largest land use category in the state.A more recent trend in land use is a shift to âwildlife managementâ use following state legislation in 1996 that created the official land use category for tax appraisal purposes....
