Wildlife specialists with the UF Institute of Food and Agricultural Sciences (UF/IFAS) depend on geographic information to determine this lizard’s potential impacts on the environment, wildlife, and human health. They need more information to stay ahead. “We receive anecdotal reports of brown basilisks in areas where the reported sightings are thin and sporadic, but we know they are thriving in South and Central Florida. There are reports of brown basilisks from the Florida Keys to Gainesville,” says Ken Gioeli, a natural resources and environment agent at University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) Extension St. Lucie County. “Residents and visitors can enhance the data by taking photos of brown basilisks and uploading them to EddMapS or the IveGot1 app.” To help residents and visitors identify the brown basilisk, a peer-reviewed Extension document is available in English and Spanish.
