The maximum rate of nitrogen uptake, calculated from rates of growth, is near 8 mg nitrogen/g dry weight of salvinia/day or about 6,000 kg nitrogen/ha/year (Room, 1986). Madsen J.D. Berkeley, California: The Calflora Database. British Fern Gazette, 10, 251-252. The species continued to be introduced to other warm regions of the world intentionally as an aquarium and water garden plant, and unintentionally as a contaminant in shipments of other aquatic plants (Oliver 1993; Nelson 1984). S. molesta has a high growth rate and three distinct growth stages. Texas Invasive Plant and Pest Council. It forms large floating mats in areas of still water. Salvinia minima commonly grows on the surface of still or slow-moving freshwater areas, such as lakes, ponds, and canals. Giant salvinia Task Force. Surfaces of ponds, reservoirs , and lakes are covered by a floating mat 10–20 cm … The leaves are of two types—oval ones that float on the water’s surface and dissected ones that hang beneath the plant and look like roots. National Agricultural Pest Information System. Lone Star Outdoor News. Louisiana State University, Baton Rouge, LA. Decomposing plant material drops to the bottom, consuming dissolved oxygen needed by fish and other aquatic life (Divakaran et al. The rapid growth rate of Salvinia molesta has resulted in its classification as an invasive weed in some parts of the world such as Australia, United Kingdom, New Zealand, and parts of America. In late spring, existing plants can provide floating mats … Mitchell, D.S. Salvinia minima has a history of being sold in the nursery trade, and is still widely available on the internet in spite of its invasive nature (Forno et al. Water Spangles spreads by being transported on nets and boat propellers, and by people dumping it from aquariums and pools. View county names by placing the mouse cursor over a particular county.

Its invasiveness is due primarily to its phenomenal growth rate: under optimum conditions it will double in size every 2-5 days and quickly cover the surface of slow moving bodies of water. State to get tough to protect Caddo, other waterways. The Alabama Plant Atlas is a source of data for the distribution of plants within the state as well as taxonomic, conservation, invasive, and wetland information for each species. Although subtle differences have been found among the members of the group, sporocarps are generally needed to tell these species apart (Forno 1983; Mitchell 1972). 1983. Sporocarps develop in elongated chains among the submersed leaves. 1980). This information is preliminary or provisional and is subject to revision.
