Invasive Plant Atlas of the MidSouth. Consortium of California Herbaria, Berkeley, CA. Hydrilla eradication program annual report 2004 - Appendix II. Plants grow vegetatively, forming thick mats that interfere with natural ecological processes and aquatic industries including boating, waterfowl hunting, rice farming, and aquaculture. Giant salvinia found in South Carolina. Table 1. Wunderlin, R.P. Solms) (Mitchell 1979). Texas Invasive Plant and Pest Council. We highly recommend reviewing metadata files prior to interpreting these data. Caudales, R., E.V. Sporocarps develop in elongated chains among the submersed leaves. The heterosporous fern clade, of which Salvinia minima is a part, contains two families, Marsileaceae and Salviniaceae. 2007. Four hairs are joined at the tips and resemble a wisk. Salvinia's growth, expressed as frond production and plant fresh weight doubling time, was significantly increased with increasing nitrogen concentration from 1.0 mg/1 to 100.0 mg/1 in the growth media. Plants maintained at 11 ppt were killed after 20 hours exposure. http://www.nbcdfw.com/news/local/Pesky-Invasive-Plant-Turns-Up-in-Another-East-Texas-Waterway-353166401.html.

EDDMapS: Early detection and distribution mapping system. It is being provided to meet the need for timely best science. Floating mats of S. molesta can be up to one meter thick (Whiteman and Room 1991), impeding navigation, reducing water flow and interfering with fishing and recreational activities (Mitchell and Thomas 1972). Alabama state survey map for Salvinia … Decomposing plant material drops to the bottom, consuming dissolved oxygen needed by fish and other aquatic life (Divakaran et al. It is a native of Central and South America that was introduced into the southern United States in the 1920’s or 1930’s. 2007. 2000. The upper surface of the floating leaves are covered in hairs that repel water. 2006. Due to its floating habit, S. molesta was utilized to treat sewage and industrial effluent (Finlayson et al. The table contains hyperlinks to collections tables of specimens based on the states, years, and drainages selected. Peck, J.H. Reproduction is strictly vegetative as spores are sterile (Mitchell 1979). National Agricultural Pest Information System. 2015. http://www.shreveporttimes.com (accessed on 14 April 2008). 2015. Water Spangles (Salvinia minima) is a Central and South American floating plant that is known for its relatively large size and its dangling roots, which are a great feeding area and refuge for aquatic animal fry. Thayer, D.D., I.A. The section is now dynamically updated from the NAS database to ensure that it contains the most current and accurate information. Tree 5(3):74-79. S. molesta has a high growth rate and three distinct growth stages. Figure 5. Rucker, J. Richerson, and V. Howard. 1966. http://www.texasinvasives.org/. http://ceris.purdue.edu/napis/maps/stsurvey.html. Spring—Native to tropics, common salvinia rarely overwinters in TVA system to continue growth in spring.Most plants are introduced annually from water gardens or isolated warm water areas.
