Lacassine National Wildlife Refuge is located in Cameron and Evangeline Parishes in southwestern Louisiana, was established in 1937 by Executive Order No.

Nesting colonies of wading birds such as ibis, roseate spoonbills, and egrets, alligators, and furbearers such as mink, otter, and raccoon and nutria are found on the refuge.

Threatened and endangered species that have used the refuge include bald eagles, peregrine falcons, and Louisiana black bear.

Lacassine NWR, known for attracting thousands of pintails each winter (a peak of 300,000), has also seen the effects of the decreasing populations.

Habitat is made more attractive to waterfowl and shorebirds by mechanical methods and flooding with costs reimbursed to the landowner or farmer.

An active volunteer program provides additional opportunities and students are able to earn college credits through an internship at the refuge.
