Ecology of the florida manatee

Manatee threats

This effort relies on private marine facilities such as zoos, large aquaria, and oceanaria and an extensive network of manatee specialists and volunteers. Like other grazing animals, Florida manatees play an important role in influencing plant growth in the shallow rivers, bays, estuaries, canals and coastal waters they call home. When you travel slowly through these areas, you give manatees a chance to safely get out of your way. To date, the highest recorded survey count occurred in January with an estimated minimum population of 5, animals. It is usually found in freshwater, brackish, and saltwater habitats. They're also migratory species. Manatees can live for several decades. The grittiness of their plant fodder explains the relentless wearing-down and replacement of manatee molars. What They Eat Manatees can weigh more than a thousand pounds and have been commonly been known to eat as much as 15 percent of their own body weight in plants each day. Sirenia Project biologists work cooperatively with federal and state researchers and managers on research identified as essential for the recovery of the species. It is certainly no longer "on the brink of extinction.

We believe that all Florida and southeast Georgia counties where manatees regularly occur in summer or winter should have appropriate manatee conservation programs in place. Important spring flows must be maintained in the Upper St. Whether natural or man-made, manatees depend on warm waters to spend the coldest days of winter.

Like other grazing animals, Florida manatees play an important role in influencing plant growth in the shallow rivers, bays, estuaries, canals and coastal waters they call home.

Aerial surveys are done every year. Both of these laws make it illegal to "take" i.

what would happen if manatees went extinct

Antillean manatees in Puerto Rico Actions needed for recovery Identify, assess and reduce human-related manatee mortality.

During winter, some manatees retreat to South Florida waters or seek out warm-water refuges such as artesian springs or -- notably -- balmy outflow from industrial facilities.

They nonetheless appear to feed most heavily on seagrasses, which are hugely important sustenance for sirenians across the globe; specific species favored by the Florida manatee include manatee grass and shoalgrass. To evaluate the population, we presently monitor statistics such as adult survival rates, reproduction, and population growth rate. Summary Great strides have been made in the protection and recovery of the Florida manatee. This makes them a primary consumer as they only eat plants like: Turtle grass. However, these surveys are inexact because of changing weather conditions, water clarity, manatee behavior, and other factors. Antillean manatees in Puerto Rico Actions needed for recovery Identify, assess and reduce human-related manatee mortality. Large sharks such as tiger and bull sharks, both of which do enter bays, estuaries and river mouths, may pose a threat to Florida manatees in those waters. Petition for critical habitat revision In , the Service was petitioned to revise critical habitat for this species. Facilitate manatee recovery through public awareness and education. Another important threat is loss of reliable warm water habitats that allow manatees to survive the cold in winter. A US Geological Survey-led team captures a manatee for a health checkup.

At this time, seven Federal manatee sanctuaries have been established to help protect the manatees at Crystal River, Florida. Manatees are also protected under the Florida Manatee Sanctuary Act. A US Geological Survey-led team captures a manatee for a health checkup. Their role in the ecosystem is as a plant eater, as they feast on over 60 species of water vegetation in the waters they live in.
