WWF works to sustain the natural world for the benefit of people and wildlife, collaborating with partners from local to global levels in nearly 100 countries.
Each year, WWF leads a team of park rangers, conservationists from Texas’s Big Bend National Park and Mexico’s National Commission of Natural Protected Areas, and the Mexican firefighters known as Los Diablos. Together they set controlled fires along remote stretches of the Rio Grande/Rio Bravo River. Why? To beat back giant cane, a highly invasive, bamboo-like grass that traps sediment and narrows the river’s flow, burying aquatic habitat and subjecting riverside communities to flooding. Eliminating the cane helps restore a shallower, wider, more natural river, improving water security for people and wildlife on both sides of the border.
