Invasive Species
Invasive species are recognized as being one of the greatest threats to conservation, management, and restoration of coastal prairie natural resources. Because of the tremendous loss and degradation of habitat in the region, the remaining fragments are particularly vulnerable to adverse effects from invaders that directly attack or compete with native biota, alter fire regimes, increase the cost or difficulty of management, and/or alter natural ecosystem processes. Natural resource managers in the region currently expend considerable time and resources combatting invaders that have moved into the coastal prairie. In addition to these well-recognized problems, there is a host of new and potential invaders that may pose increasing and future problems.
Our goals are
(1) to understand the mechanisms and consequences of invasion, (2) to facilitate prevention and control of unwanted invaders, and (3) to forecast future problems that may be posed by recent or new invasions.
A List of Some of the Most Troublesome Invasive Plants in the Coastal Prairie Region:
Scientific Name |
Common Name |
Triadica sebifera (a.k.a.Sapium sebiferum) |
Chinese tallow |
Salvinia molesta |
Giant salvinia |
Eichhornia crassipes |
Water hyacinth |
Tamarix sp. |
Salt cedar |
Rosa bracteata |
Macartney rose |
Coastal Prairies and wetlands are also
being invaded by exotic animal species. One such animal is the nutria
(Myocastor coypus). Nutria are basically herbivorous and marsh loss
has coincided with the introduction and expansion of the population in Maryland
and along the Gulf Coast region.
