state, with an additional 19 species listed as possible or probable breeders. The Great Florida Birding Trail, a 2000-mile (3200 km) long trail, is composed of 489 locations throughout the state which are optimal observation sites. Sport fishing is also popular in Florida; over 250 different species of fish (including 73 non-native species) can be found in Florida. There are more than 1000 species of fish in Florida's inshore waters. In 2010, NOAA, citing the Magnuson-Stevens Act, banned fishing of red snapper until the population has time to recover. Florida's Atlantic coast is home to the only extensive coral reefs in the continental United States, and the third largest in the world. The entire reef system in the Florida Keys is encompassed by the Florida Keys National Marine Sanctuary, and significant portions of reef are protected as part of Biscayne National Park. In 1977, the federal government placed alligators on the endangered list. They were removed from the endangered list in 1987 and Florida permitted selective hunting in 1988. Bird and turtle habitats In 1987, Florida hosted the last member of the dusky seaside sparrow, now extinct. There have been only two such avian failures since listing of endangered species began in 1973. This event has presented a challenge to ensure that other environmental concerns are addressed in a timely manner. The Florida scrub jay has been thought to be threatened for many years, because the species is territorial and cannot move to better grounds when its habitat is jeopardized. Nesting beaches of loggerhead sea turtles are protected. Environmental issues Invasive species Native flora is threatened by various invasive plants, including the Brazilian pepper (Schinus terebinthifolius). Possession and cultivation of this tree is illegal. Large numbers of volunteers periodically cut down these invaders, particularly along waterways. The Australian pine (Casuarina spp.) is being actively controlled to prevent it from spreading. Other foreign pests include the Asian ambrosia beetle (Xyleborus glabratus) threatens the local avocado industry and redbay trees (Persea borbonia). It is illegal to import giant African land snails (Achatina fulica). These threaten buildings, 500 types of local plants, and carry meningitis. In 2015, the land flatworm Platydemus manokwari was reported from Miami. It is a highly invasive species, and, as a predator of snails, a threat to biodiversity.
