The annual Cornell Cooperative Extension In-service invasive species conference happens this week at Cornell University in Ithaca. Invasive species are a big topic these days and New York State has set up a total of eight parnerships called PRISMs (Partnership for Regional Invasive Species Management) statewide to deal with them. These are mainly funded by the Environmental Protection Fund and you can find a map and more information about them by clicking HERE. Look at the map and see which PRISM you are in. I coordinate the Long Island PRISM called LIISMA (Long Island Invasive Species Management Area) which includes Staten Island too. We have many partners who manage many invasive species across the islands that comprise New York’s coastal plain. LIISMA and the Lower Hudson PRISM span the most developed area of the state and thus we have the most invasive species infestations to deal with. We are also frequently finding new exotic species coming in from the south on their own or by the many horticultural and animal trade pathways that criss-cross this densely populated and fragmented area. We are always on the lookout for new species so we can evaluate their threat and take action before it is too late and they become too common to eradicate. Once a species becomes common it will never be eradicated unless it is affected by a pathogen that kills it completely and this rarely happens. That is why we put so much effort into prevention and early eradication of invasives. The Cornell conference will start off with a session on biological control which is one way managers can help suppress the most egregious invasives on a large scale. This technique is not without its problems and these will be discussed by a panel of experts. Other topics to be discussed will be invasive species research, communication science, agricultural pests, early detection and rapid response, and a statewide species survey. The twitter site @liisma_prism will be tweeting some of the highlights in the next few days so check in with them from time to time if you follow Twitter. If you have any questions about invasives, a good place to start is with the website http://www.nyis.info or the coordinator of your local PRISM.
