Invasive species are species that are not native to a particular ecosystem and can cause significant damage to the native species, environment, and the surrounding economy this has been very prevalent for the catskill community in the recent years there has been a spread of invasive species pushing the native ones out of there habitat.
Examples of invasive species:
Japanese knotweed, is native to japan the native aquatic species are not able to process the knotweed leaves as well as threatening the native species, Japanese knotweed can cause some environmental issues.
- To remove Japanese knotweed cut canes and allow them to dry out, then burn them. On no account add them to your normal household waste.
- Leaves: Lush green, heart or shovel shaped leaves
- Flowers: Clusters (Panicles) of small creamy white flowers
- Habitat: domestic gardens, Riverbanks, wooded area.Further identification
Northern Snakehead, a commonly know predatory fish from Asia, are extreme eaters that could patently reduce or eliminate native fish. The aquatic communities may suffer losses if the Northern Snakeheads should continue to populate the Catskills rivers
- The potential control methods for a snakehead infestation are limited however Physical removal of the fish using nets, traps, angling, electrofishing or biological control by introduction of predators are likely to be successful for small infestations. If the infestation is believed to be to a more than a few individuals the above techniques may be unsuccessful in removing the targeted organisms
- Appearance: The northern snakehead has a long, thin body that can grow to 47 inches and 15 pounds. It has a somewhat flattened head with eyes located in a dorsolateral position.
- Habitat: Ponds, lakes, streams, rivers and other freshwater areas. Can live out of water for up to four days if kept moist and will lie dormant in mud during droughts.
- Range: Found in the Potomac River and several of its tributaries in Maryland and Virginia. Native to China, Russia and Korea.
- Spotted lantern-fly, is an invasive species from Asia that primarily feeds on wide variety of fauna such as grape vines, maple, walnuts, and fruit trees, this insect can impact New York’s agricultural community as well as the lush forests.
- Removing or destroying eggs will decrease numbers over time.
- Put pesticides on targeted trees/plants.
Appearance: The spotted lantern-fly is about an inch long and half an inch wide. The forewings are gray with black spots. When flying, it exposes its red and blackhind wings. The lantern-fly has a black head, black legs and a yellow abdomen with black bands.
Habitat: Spotted lantern-flies can live on a variety of host plants, including fruit trees, grape vines and various hardwoods. Their preferred host, especially as adults, is the tree-of-heaven, which is also an invasive species.
Range: The spotted lantern-fly has been seen in parts of Pennsylvania, Delaware, New York and Virginia.
Potential: Stilling grow outwards at a rate of ten miles each year they have the potential to destroy the keystone states wine, craft beer, wood and apple products.
- Hydrilla, is one of the most difficult invasive species to control and eradicate due to the dense consistency can have negative impacts on recreation, tourism and aquatic ecosystems.
- There are several options to control the spreading of Hydrilla Use a season long herbicide such as Pond Logic or WipeOut this method should quickly remove Hydrilla.
- Appearance: has pointed, bright green leaves about 5/8 inches long, the leaves have small teeth or serrations on the edges and at the tips.
- Habitat: The Hydrilla can be found in a variety of aquatic habitats such as reservoirs, lakes, ponds, springs, rivers, and tidal zones. It can tolerate a wide range of water chemistry conditions.
What Can New York Do prevent Invasive species?
- Clean, drain, and dry all watercraft, trailers and gear after and before visiting a waterbody.
- Buy and burn local firewood.
- Use native plants in gardening and landscaping.
- Be a responsible aquarium and exotic pet owner—never dump or release species into the wild.
- Trainings on Best Management Practices
