Francine Cohn Preserve is one of the most important colonial waterbird nesting islands.

Overview

Description

Sitting just off the Texas coast in the Gulf of Mexico is a string of island refuges for wildlife. One of the central “pearls” in this string is the Francine Cohn Preserve, just south of Port Aransas on Mustang Island’s western face. This 300-acre preserve is about a mile from The Nature Conservancy (TNC)'s Shamrock Island Preserve, one of the most important nesting sites for colonial waterbirds. As a result, Francine Cohn’s marsh habitat serves as a foraging site for rare and other waterbird species at this island rookery. Migrating and resident songbirds, shorebirds, raptors and wading birds also use the area for feeding, resting and roosting.

The preserve’s marshy wetlands are dominated by smooth cordgrass, seagrasses and glassworts. Upland areas of the preserve showcase gulf cordgrass and seacoast bluestem. And, along the beachfront at Francine Cohn, a rare population of black mangrove thrives in the saltwater.

Why This Place Matters

Among the rare species recorded at the Francine Cohn Preserve are the piping plover and reddish egret, both of which are listed as threatened, and the peregrine falcon, which is endangered in Texas. A few of the many other bird species using the preserve are great blue herons, ibises, roseate spoonbills and tricolored herons.

This site is also a key marine conservation area, providing essential habitat for numerous fish and other species that are commercially and recreationally important. These include red drum, southern flounder and speckled trout, plus blue crabs and brown shrimp. Although all of these are common in preserve waters, populations of the blue crab, for instance, have been in decline in the Gulf in recent years, with reduced freshwater sources and habitat loss among the likely culprits.

What TNC Is Doing

The Francine Cohn Preserve was established by TNC with a 1999 donation by Marcus Cohn of 22 acres, followed by the April 2000 purchase of 278 adjoining acres from a private landowner with the vital assistance of the Coastal Bend Bays and Estuaries Program, Koch and Citgo. The preserve now abuts more than 47,000 acres of state park, thanks to Texas Parks & Wildlife's expansion of Mustang Island State Park in 2015.

Here, TNC is focusing on protecting the preserve’s rare freshwater wetlands, as well as the ecological health of its various marsh systems and tallgrass coastal prairie. This work is an important part of TNC’s efforts to safeguard Texas's barrier island systems from threats like coastal development, habitat fragmentation, pollutants that harm wildlife and native lands, off-road vehicle use and loss of wetlands.
