Project Description: 

This project involved restoration of an abandoned gravel pit excavated below groundwater and enhancement of the aquatic resources. One small stand of Japanese knotweed was also eliminated. The Nature Conservancy owns 1,700 acres known as the Basin Preserve. At the time of acquisition, the Conservancy inherited an abandoned gravel pit where extraction below groundwater level resulted in four year-round pools; no attempts were made to restore the pit at the time of abandonment by the prior owner. The 7-acre gravel pit consists of barren soil around old roads, four ponds totaling approximately 1.1 acres, primarily old field vegetation, and stockpiled overburden of sand and gravel with limited organic matter. The pit was being accessed by unauthorized motorized vehicles, resulting in soil erosion and damage to the limited natural vegetation.
