An exotic antelope from Asia called the nilgai was released in Texas in the United States in the 1930s as hunting game and is now not only a nuisance for cattle ranchers, but it also eats mangrove leaves. Mangroves are survivors. They improve water quality by filtering runoff and polluted waters. Also, on some isolated tropical islands, such as Hawaii and Tahiti, mangroves are not native and are sometimes considered invasive species.
