Environmentalists and outdoor enthusiasts visit Perdido Key due to the miles of protected beach wilderness; along with the
Navarre Beach Marine Park and the many miles of
Gulf Islands National Seashore, the protected coastlines are a signature of the
Pensacola Bay area and the remainder of
Northwest Florida. Perdido Key's two state parks and an expanse of National Seashore offer chances to spot gray foxes and blue herons in the wild. Local outfitters offer guided tours, and self-guided nature trails at Big Lagoon and Johnson Beach allow solitude.
Perdido Key Beach Dune Habitat The azure waters of the
Gulf of Mexico frame the white beaches. These beaches and their dune habitat host a variety of visitors and residents throughout the year. The beach dune habitat of Perdido Key is characterized by several rows of sand dunes. "Frontal" or "primary" dunes are vegetated with grasses including
sea oats, bunch grass, and beach grass. Among other plants growing in primary dunes are Florida
rosemary,
railroad vine and beach
morning glories. "Secondary" dunes, further inland, support saw palmetto, slash and sand pines, and scrubby shrubs and oaks. Growing among the dunes are such species as cordgrass, salt-grass, pine trees, purslane and pennywort. The scrub and grasses growing on the dunes are vital to the health of Perdido Key's beach habitat. The roots of plants are the "fingers" which hold sand in place, preventing it from blowing away in the wind or washing away in the tidal surge of
Hurricane or other storms. Without the critical holding power of dunes and their plants, the beaches would blow and erode away. The
dune restoration project on Perdido Key is restoring or planting the following native plants: ---- Sand plants: • sea oats (Uniola paniculata) • saltmeadow cordgrass (Spartina patens) • coastal panicgrass (Panicum amarum) Estuarine plants: • turtle grass (Thallassia testudinum) • salt marsh cordgrass (Spartina alterniflora) • black needle rush (Juncus romerianus)
Wildlife Perdido Key is home to the endangered
Perdido Key beach mouse. The small white and gray mouse, weighing 13-16 grams, blends in with the white quartz sand of northern Gulf coast beaches. While the Perdido Key beach mouse feeds primarily on the seeds of sea oats and bluestem, it will occasionally eat insects. The Perdido Key beach mouse was listed as an
endangered species in 1985. Loss of habitat to development is considered to be the main factor leading to the decline of the species. Hurricanes have also taken their toll on the mouse. The beach mouse population at Perdido Key was nearly eliminated in the mid-1990s when hurricanes Erin and Opal ravaged Perdido Key. Numbering less than 40 after the storms, the mice have regenerated quite well, with current population estimates near 500. While populations appear to be growing, the Perdido Key Beach Mouse will probably never make it off the
endangered species list because of continued
habitat loss and degradation due to human development in the area. Other species find the white sands attractive as seasonal homes or for nesting before returning to sea. Two such visitors are the piping plover and the sea turtle. The
sea turtle is another endangered visitor to Perdido Key.
Loggerhead,
leatherback,
ridley, and
green sea turtles arrive between May and September to dig nest cavities in the sand into which 100 or more
eggs are laid. About two months later, provided the nest has not been washed away, uncovered by high winds, or disturbed by
predators or beach visitors, turtle hatchlings emerge. Following the brightest spot in the sky, which is usually the horizon over the water, hatchlings scramble for the sea. With development on
barrier islands, lights of convenience stores, hotels and businesses (see
Light pollution ) have made the trek to the sea confusing and dangerous. Few hatchlings are successful in their first adventure. Less than 1% of hatchlings survive their first year and grow old enough to return to Perdido Key to resume the cycle. Shorebirds including black
skimmers,
gulls,
terns, and brown
pelicans are among the birds which rest on the island, nest, or feed offshore. Neotropical birds, such as
warblers and
cedar waxwings, live in the
tropics and travel to North America to breed, stopping over to feed and rest at Perdido Key.
Monarch butterflies migrating to and from South America stop here, finding refuge on the sea oats growing in the dunes of Perdido Key. == Local attractions ==
