Attachment_1_2026_Tree_Data_Spreadsheet.xlsx

This is a tree data spreadsheet containing an inventory of hazard trees identified for mitigation across multiple locations within what appears to be a National Park Service property. The spreadsheet documents 170 individual trees across four geographic areas: Bolivar Heights, Potoma Wayside, Maryland Heights, and Appalachian Trail sections. Each tree entry includes identification data (tag number, object ID, GPS coordinates with latitude and longitude), botanical classification (common name and scientific name), physical characteristics (diameter at breast height in inches, height in feet, and number of stems), and recommended treatment action.

The treatment recommendations are divided into two primary categories: REMOVE and PRUNE. The REMOVE designation applies to 118 trees, including invasive species such as Tree of Heaven (Ailanthus altissima), which appears 29 times throughout the dataset, as well as dead or hazardous native species. The PRUNE designation applies to 52 trees, predominantly healthy native oaks, maples, and ash species that require maintenance rather than removal. Specific tree species targeted for removal include Box Elder Maple, White Ash, Elm, Mocker Nut Hickory, and Sassafras, while species marked for pruning include Black Oak, Northern Red Oak, Red Oak, Black Walnut, White Oak, and Chestnut Oak. Additional columns for vine presence and GPS coordinates in feet are included for certain location groupings, indicating the data supports field operations planning for the hazard tree mitigation contract solicitation HAFE FY26 HAZARD TREE MITIGATION issued by the National Park Service.
