Les Naturalistes belges 64, 199–221. It is a free floating plant that does not attach to the soil, but instead remains buoyant on the surface of a body of water. Although this is not likely to be a significant pathway, awareness-raising campaigns on the movement of invasive alien plants by this pathway may help to reduce its entry along this pathway. Israel Nature and Parks Authority. They have also been used to extract nutrients and pollutants from water. Identification. Salvinia molesta was specifically defined as a Category 1b ‘invader species’ on the NEMBA mandated list of 2014. This warning label informs customers about the risks associated with plant invasiveness, and provides instructions for ownership designed to reduce the risk of release of the plant to the environment (Verbrugge et al., 2014). Predicted distribution of Salvinia molesta in the United States. Um mehr über die Verbreitung von invasiven gebietsfremden Arten zu erfahren sind wir auf Ihre Hilfe angewiesen. https://www.eppo.int/INVASIVE_PLANTS/ias_plants.htm [accessed on 29 September 2017]. What does salvinia look like? Taxonomy: Scientific and Common Names for This Species, Native species That Resemble Giant Salvinia. Monitoring and Mapping Invasive Aquatic Weed Salvinia molesta using Multispectral Remote Sensing Technique in Tumaria Wetland of Uttarakhand, India. Water fern is about three-quarters of an inch long. Booy O, Wade M & Roy H (2015) Field Guide to Invasive Plants and Animals in Britain. 378–407. Oliver (1993) concludes that mechanical harvesting is not economically competitive compared to chemical control, and that the large biomass associated with severe infestations can make the use of both harvesting machines and hand removal impractical. Final Report, 35 pp. Boat Slip Clogged with Giant Salspecies can be separated (2.5-3.8 cm) long, oblong, and vary in color from green to gold to brown. In France, the species was first found in Corsica in 2010, in a water reservoir (Paradis & Miniconi, 2011). The presence of a mat of S. molesta is likely to degrade the water quality beneath it by blocking sunlight, resulting in decreases in dissolved oxygen and pH, and increases in concentrations of CO2 and H2S (Mitchell, 1969; McFarland et al., 2004). Salvinia molesta has spread widely throughout the world, becoming an invasive alien species in many regions. Kasselmann C (1995) Aquarienpflanzen, 472 pp. The smaller, yet, similarly invasive S. minima was first documented in the United States in the late 1920s. Jacono CC & Pitman B (2001) Salvinia molesta: around the world in 70 years. In the case of the latter, in 1962 at the peak occurrence of the species, over a quarter of the lake was covered by the plant (McFarland et al., 2004). Vandecasteele B, Quataert P & Tack FMG (2005) Effect of hydrological regime on the metal bioavailability for wetland plant species Salix cinerea. Salvinia molesta prefers tropical, sub-tropical or warm temperate areas of the world and grows best in still or slow-moving water bodies including ditches, ponds, lakes, slow rivers and canals. Salvinia molesta is a free-floating aquatic fern native to Brazil. Marshall B E, 1993. Giant salvinia is an aquatic fern with floating leaves that are 0.5 to 1.5 in. S. molesta can form thick mats of up to 1-meter-thick. 1. The accumulation of S. molesta litter at the bottom of a water body may also reduce habitat suitability for breeding fish (Sculthorpe, 1985). Mitch. Control of S. molesta did not exceed 39% with imazamox or imazapyr but was 89% with glyphosate. The surfaces of the leaves have rows of arching hairs that look like little eggbeaters. 2–3 (Pteridophytes) (Eds Wu ZY, Raven PH & Hong DY), pp. Salvinia molesta is most often found in stagnant or slowflowing waters such as lakes, slow-flowing rivers or streams, wetlands, rice paddies, irrigation channels, ditches, ponds and canals (EPPO, 2016). Salvinia molesta (giant salvinia) is a floating aquatic fern (family Salviniaceae) found in the lower Colorado River and its drainages in the Sonoran Desert, and in San Luis Obispo County, California.
