Summary
This refined map was created to help assess possible spread of nonindigenous aquatic species distributions due to flooding associated with Hurricane Harvey. Storm surge and flood events can assist expansion and dissemination of nonindigenous aquatic species through the connection of adjacent watersheds, backflow of water upstream of impoundments, increased downstream flow, and creation of freshwater bridges along coastal regions. This map will help natural resource managers determine potential new locations for individual species, or to develop a watch list of possible new species within a watershed. These data include a subset of data from the Nonindigenous Aquatic Species Database, that fall within the general area of the 2017 Hurricane [...]
Summary
This refined map was created to help assess possible spread of nonindigenous aquatic species distributions due to flooding associated with Hurricane Harvey. Storm surge and flood events can assist expansion and dissemination of nonindigenous aquatic species through the connection of adjacent watersheds, backflow of water upstream of impoundments, increased downstream flow, and creation of freshwater bridges along coastal regions. This map will help natural resource managers determine potential new locations for individual species, or to develop a watch list of possible new species within a watershed. These data include a subset of data from the Nonindigenous Aquatic Species Database, that fall within the general area of the 2017 Hurricane Harvey flooding.
This data is intended to help managers in Texas and Louisiana know what new species to monitor for in each drainage. It also gives them the ability to target a particular species and know where to look. Maps display the identified areas of flooding and show areas that experience sufficient flood heights to connect adjacent drainages. The dataset provides information on the nonindigenous aquatic species that are currently established in each drainage and the species that have the potential to move between flooded drainages. These depictions are very generalized, and animals and plants may not have had the opportunity to move into all of these new areas.
