PAD-US 1.1 (CBI Edition): Areas under secondary threat from the Deepwater Horizon Gulf of Mexico oil spill, determined by 06/27/2010 USF Trajectories.

Jun 24, 2010
These protected areas were estimated by the Conservation Biology Institute as being secondarily threatened by the corresponding Deepwater Horizon oil spill trajectory forecast in the Gulf of Mexico. This dataset is extracted from PAD-US 1.1 (CBI Edition), and the original metadata has been included here, below.

First, protected areas within 1 mile of the entire study area coastline (TX to NJ), or that intersect hydrological feature polygons from the NHDPlus National Hydrography Dataset within the 1-mile coastline buffer, were extracted from PAD-US 1.1 (CBI Edition). Then, protected areas were identified as being under primary, secondary, or tertiary threat from the oil spill. The probability of being affected was determined using the University of South Florida's Deepwater Horizon oil spill trajectory forecast from the WFS ROMS numerical model, as projected for 06/27/2010 at 00h UTC ( ), and a 75,000 m2 grid over the study area (see Projected Deepwater Horizon oil spill distribution, updated for 06/27/10 at ).

Original Metadata abstract:
Protected areas are cornerstones of national and international conservation strategies. By way of these designations, lands and waters are set-aside in-perpetuity to preserve functioning natural ecosystems, act as refuges for species, and maintain ecological processes. Complementary conservation strategies preserve land for the sustainable use of natural resources, or for the protection of significant geologic and cultural features or open space. PAD-US 1.1 (CBI Edition) attempts to include all available spatial data on these places. It is our goal to publish the most comprehensive geospatial data set of U. S. protected areas to date.

PAD-US 1.1 (CBI Edition) is limited to the continental U.S., Alaska, and Hawaii. It does not include protected areas data for U.S. territories at this time.

The PAD-US 1.1 (CBI Edition) data set portrays the nation's protected areas with a standardized spatial geometry and numerous valuable attributes on land ownership, management designations, and conservation status (using national GAP and international IUCN coding systems). The PAD-US 1.1 (CBI Edition) defines protected area to include all lands dedicated to the preservation of biology diversity and to other natural, recreation and cultural uses, and managed for these purposes through legal or other effective means (adapted from IUCN definition). The database represents the full range of conservation designations that preserve these natural resources in the United States. Our database does not distinguish a protection threshold above which biodiversity is considered secure. Instead, a complete suite of protected area attributes are provided for each polygon with the purpose of giving users the information they need to define the most relevant conservation thresholds for their own objectives and requirements. Collaborating with the nation's leading data providers, the goal is to provide an annual update.
