What's Invasive! is a system to enable citizen science participation in identifying and finding invasive plant species. With the use of mobile phones, data on location and weed species can be collected and sent to the What's Invasive database. These data are useful to the National Park Service experts who are in charge of monitoring and controlling invasive plant species threats.

The idea is that a small set of invasives (both plants and separately animals), from the huge list of all possible invasives, can be sent to a mobile phone based on the phone's location, enabling a user to choose from a smaller set of species to identify.

Anyone can set up a list of invasives that is associated with a specific latitude/longitude (a "park"). The phone apps (both Android and iPhone apps are free) will then pick the list that is closest and display that list for the user to select from.

All data is sent to the What's Invasive! server and put on a map. All data is also freely available for download by anyone, through the website. We are currently collaborating with Invasives.org to get our data automatically inserted into their database as well.
