Port of the Islands

Dolphins

We left Everglades National Park and the Homestead area to travel to our next destination, the Port of the Islands Everglades Adventure Resort located on the Tamiami Trail about 15 minutes east of Naples. Upon entering the Tamiami Trail we noticed a canal running parallel to the north side of the road bordered by a large dyke; because of the number of egrets, Anhingas and other waterbirds flying in and out of the area, we assumed there was a large wetland just out of view. Indeed, there is a large water conservation area to the north of the highway, which historically provided the Everglades with a steady supply of fresh water.

When the Tamiami Trail was built in the 1920s, it created an enormous dam across the shallow, 70-mile-wide River of Grass and blocked the main corridor of fresh-flowing water into Everglades National Park. Although 19 culverts built beneath the Tamiami Trail permit some flow of water, the amount of water entering the Everglades is much diminished. Unnaturally low water levels for over 90 years have significantly damaged sawgrass marshes, tree islands, fish reproduction, wading-bird nesting sites, and the habitats of many endangered species unique to the Everglades. The southerly-flowing fresh water no longer counterbalances the seepage of salt water inland, upsetting the delicate balance of nature. In order to increase the water’s flow, one bridge has already been built to replace a mile of the old road, but it will take years for the remaining 5.5 miles’ worth of bridges to be built and assist in the restoration of the Everglades.
