Description: These data show the observed distribution of lion fish in south Florida from 2010-2013 only. They were compiled by Pam Fuller from USGS and are continually updated and corrected. Please visit (http://nas2.er.usgs.gov/viewer/omap.aspx?SpeciesID=963) to view the real-time map. Lionfish are an invasive species in the United States. They inhabit natural (e.g., reef) and artifical structure (e.g., wrecks) at depths from just a few inches of water to over 300 m. In the invaded range, lionfishes have been found in a variety of habitats, including reefs, wrecks, bridge pilings, seagrass and natural hardbottom. In the U.S., lionfishes have rapidly increased in abundance. The data points that are displayed do not constitute the total dataset. Not all specimens/reports are included in the database; after a species is well-established in an area data are no longer entered. The data shown on the map accurately depict the extent of the areal coverage of lionfish, but do not include all points for all times. Data is constantly added and corrected, so the dataset changes on a daily basis. The USGS is the national repository for non-native aquatic species, and so the database is compiled of several datasets from partnering agencies and cooperators as well as the general public. It is pieced together from many different sources. Not all sites are sampled in all years, they are opportunistic reports. This data set should not be assumed to be complete. This data is not comprehensive of all introductions in all localities. Hence, these data should not be the sole source for analysis. The goal is to show distribution; not to document abundance. Thus, the dataset is not amenable to the same types of analyses that data from a monitoring program would be (e.g., there are no negative values).
