We built a citizen science website (www.citsci.org) between 2005 and 2008 (Figure 1) to
support volunteers who collect and report invasive species data (Crall et al. 2010). The website
uses technology developed by our team (Graham et al. 2007) and engineered to provide fast
and reliable online interactive mapping capabilities at multiple spatial and temporal scales.
This technology drives several related websites through targeted web skins, including the
USGS National Institute of Invasive Species Science (www.niiss.org), the Global Invasive
Species Information Network (www.niiss.org/gisin; Graham et al. 2009), an environmental
literacy assessment website (www.niiss.org/msp), and a website dedicated to the invasive
species Tamarisk (www.tamariskmap.org).
