All sightings of other Salvinia species must be reported to Biosecurity Queensland within 24 hours of the sighting. Buds are killed when exposed for more than two hours to temperatures below -3°C or above 43°C. All other Salvinia species are prohibited invasive plants. It spreads aggressively by vegetative fragments.
In standing water it forms stable floating mats. The plant itself has to be physically tranported as it cannot move from one aquatic system to another unaided. • Infestations are widespread on the east coast of Australia but could spread elsewhere. Salvinia molesta D.S.
Mitchell Floating fern family (Salviniaceae) Origin: South America. The leaves of Salvinia Minima are buoyant, spongy, light green, round-oval in shape and measuring about 1/4 inch across. Animals and water birds are therefore a significant means of spreading the weed.
Keypoints • Salvinia is a major aquatic weed threatening waterways around Australia. Salvinia molesta is a floating aquatic fern that thrives in slow-moving, nutrient-rich, warm, freshwater. Salvinia Minima Salvinia Minima, known also as water spangles or water fern.Salvinia Minima is a small, green, floating plant, growing in small clusters.Salvinia Minima is an aquatic fern that can form into dense mats upon the surface of the water. Even though it is prohibited from sale in New South Wales, occasionally, it is traded as an aquarium plant. • Public education will help to prevent spread because infestations are caused by human activities. It is dispersed long distances within a waterbody (via water currents) and between waterbodies (via animals and contaminated equipment, boats or vehicles). Giant Salvinia . Salvinia molesta. “Salvinia molesta […] grows best in still or slow-moving water bodies including ditches, ponds, lakes, slow rivers and canals. The hairs on their leaves have an eggwhisk-like form. It grows optimally at a water temperature of between 20°C and 30°C. Background Giant salvinia, also known as water fern or kariba-weed, was introduced as an ornamental aquatic plant and is spread to new water bodies on boats and fishing gear, by dumping of aquaria, and by other unintentional means. Salvinia minima is a very undemanding, nice floating plant for aquaria that grows well under moderate light.
It must not be given away, sold, or released into the environment without a permit. This is an easy way to discern Salvinia minima from S. molesta and other species of the group of plants related to Salvinia auriculata. Salvinia molesta is a restricted invasive plant under the Biosecurity Act 2014.
