Invasive Plants
Invasive Plants
An invasive species is an introduced species that has established itself and threatens the diversity and/or stability of a native species or environment. WARC researches the basic biology and environmental tolerances of these plant and animal species to provide resource managers with the ecological facts they need to help mitigate and control these problematic species. The Nonindigenous Aquatic Species Program monitors, analyzes, and records sightings of non-native and invasive aquatic plant species throughout the United States, such as hydrilla and floating water hyacinth.

Winter Climate Change and the Northward Range Expansion of Tropical Invasive Plants in the Southeastern United States
Using temperature, species occurrence, field-based freeze damage data, and regression analyses for 84 invasive species, researchers at WARC are quantifying the species-specific relationships between minimum temperature and plant presence.
The Nonindigenous Aquatic Species Alert Risk Mapper (ARM)
The Nonindigenous Aquatic Species (NAS) program has developed a new tool, the NAS Alert Risk Mapper (ARM), to characterize waterbodies in the conterminous U.S. and Hawaii at potential risk of invasion from a new nonindigenous species sighting.
The Nonindigenous Aquatic Species Flood and Storm Tracker (FaST)
Storm-related flooding can lead to the potential spread of nonindigenous (or non-native) aquatic species into waterways they have not been seen in before. The USGS Nonindigenous Aquatic Species program has developed an innovative mapping tool to help natural resource managers with post-storm nonindigenous aquatic species detection and assessment efforts.
Decision Analysis to Help Improve the Effectiveness of Invasive Plants Management
Melaleuca is an invasive tree that is highly problematic in the Everglades, threatening native wildlife and habitat. USGS is helping to improve management strategies for the invasive plant.
Integrating Science and Management for Optimal Prevention and Control of Invasive Nymphoides in Florida
Two invasive species of floating hearts, Nymphoides cristata and N. indica , are actively managed in Florida. A rare native species, N. humboldtiana, has been found in Florida and verified by molecular methods; this species is nearly indistinguishable from N. indica .
Nonindigenous Aquatic Species (NAS) Program
Welcome to the Nonindigenous Aquatic Species (NAS) information resource for the United States Geological Survey. Located at Gainesville, Florida, this site has been established as a central repository for spatially referenced biogeographic accounts of introduced aquatic species. The program provides scientific reports, online/realtime queries, spatial data sets, distribution maps, and general...
