Horse lovers have sued the Army over plans to evict about 700 feral horses from a western Louisiana Army base and national forest areas it uses for training.
The lawsuit calls the horses a significant historical and cultural part of Fort Polk and says the Army's plan will send many to slaughter. It contends that the Army omitted steps required to create its plan to put groups of horses up for adoption by nonprofits.
The Army says the horses are a safety risk in training areas.
The Tulane Environmental Law Clinic sued Wednesday in federal court in Baton Rouge for Pegasus Equine Guardian Association, created to protect the horses.
Earlier this month, the Humane Society of North Texas said it would bring nearly 400 of the horses to Texas.
