Parks in this Network
Gulf Coast Network
The network's habitat variation includes barrier islands/seashores, coastal fresh to brackish marshes, bottomland hardwoods, cypress-tupelogum swamps, Mississippi River alluvial floodplain and loessal bluffs, rolling hill country and pastures, and the dry scrub/grasslands of Edwards Plateau.
This site provides access to study results, data, and related analysis about the natural resources investigated by the GULN network, its parks, research, and land management partners. Park managers use this information to make decisions about park resources.
Water quality and quantity is monitored quarterly at six locations within the Preserve as directed by the GULN.
Sampling is performed at 13 sites proximal to the Preserve by the LNVA and at 6 stations in the Lower Neches River Valley by the USGS.

Water Quality of San Antonio Missions National Historical Park
In a semiarid land like south-central Texas, the spring-fed San Antonio River has been a cultural oasis for centuries. The importance of this water is evident throughout the 331 hectares (ha) of San Antonio Missions National Historical Park (SAAN).

Select a Species Category (optional):
A Checklist A Checklist contains only those species that are designated as "present" or "probably present" in the park.
The Full List with Details includes all the Checklist species plus species that are unconfirmed, historically detected, or incorrectly reported in the park. The Full List also contains species that are "in review" because their status in the park hasn't been fully determined. Additional details about the status of each species is included in the Full List.
The Checklist will almost always contain fewer species than the Full List.
