About this file
These documents are mapping and tracking files for invasive Golden Bamboo located within the Colonial National Historical Park, specifically at three locations: Yorktown Beach, Windmill Point, and Cornwallis Cave. The files include detailed geospatial maps showing bamboo growth areas across different years (2011-2023), with precise acreage measurements ranging from 0.51 to 1.85 acres per location. The maps use color-coded overlays to indicate federal land ownership (fee and less than fee), topographical contours, and the extent of bamboo invasion, supporting the National Park Service's invasive species management efforts.
The documents are part of a larger context for solicitation 140P4325Q0052, titled "COLO BAMBOO HERBICIDE TREATMENT", which aims to remove invasive species to restore viewsheds and protect cultural resources at Yorktown. The mapping data provides critical visual documentation of bamboo spread over time, likely serving as technical background for planning targeted herbicide treatment and ecological restoration activities within the Colonial National Historical Park.
