During that period, the company clearcut more than 86,000 acres (350 km²) of virgin pine forest in Newton, Jasper and Sabine counties.
In its heyday, the mill could process approximately 200,000 feet of longleaf yellow pine every 10 hours.
Although Wier Longleaf Lumber Company provided jobs in this area of the rural South during the Great Depression, it was at the expense of tremendous environmental damage and diminishment of ecological diversity.
Whereas before the region was home to southern magnolia, black cherry, and white ash trees, the company reseeded the area with faster-growing loblolly pines.
Because by an act of the State of Texas much of this area is now legally protected, the region has begun to redevelop its prior biodiversity.
