FORT LAUDERDALE, Fla. (AP) - A corporate park next to Interstate 95, a landfill and a set of retention ponds along Florida's Turnpike are among the unlikely wildlife refuges that have become vital to many species in South Florida.
    
Wildlife experts tell the Sun Sentinel (http://sunsent.nl/ssTWgJ) that with suburban sprawl, species such as migratory birds are forced to rely on scraps of habitat that remain green amid all the concrete and steel.
    
As wildlife habitat shrinks, more attention is being paid to what's left. The National Wildlife Federation awards wildlife habitat certification to homeowners, businesses and others that provide water, cover and food sources.
    
Broward County leads the nation in certified wildlife habitats, with 2,607. Palm Beach County has 409 certified wildlife habitats and Miami-Dade County has 428.
