KEY BISCAYNE, Fla. (AP) - Miami-Dade County hopes a network of buoys will help protect its reefs from anchor damage.

The county's year-old "Adopt-a-Buoy" program allows boaters to tie up to a flotation device instead of dropping anchor to the sea floor.

So far, 24 buoys have been installed from the Broward County line to Biscayne National Park. Thirteen more buoys are planned.

The project has cost $60,000 and Miami-Dade's Department of Environmental Resources Management is seeking grants and donations to install and maintain the buoys.
