Inventory & Monitoring at Herbert Hoover National Historic Site

Cottage at Herbert Hoover National Historic Site.

NPS

Herbert Hoover National Historic Site, established in 1965, is approximately 187 acres with natural resources, including a small tributary to Wapsinonoc Creek referred to as Hoover Creek, reconstructed prairie, woodlots, and associated habitat. The natural resources on site contribute to the park mission by creating a serene landscape to commemorate the life and times of the 31st United States President.

The park includes 86 acres of reconstructed tallgrass prairie, several small treed woodlots, scrub and treed or scrub riparian areas, and a 40-acre abandoned row-crop farm. The reconstructed tallgrass prairie was originally seeded in the spring of 1971 with five species of native grasses: big bluestem (Andropogon gerardii), switchgrass, Indian grass (Sorghastrum nutans), little bluestem (Schizachyrium scoparium), and sideoats grama (Bouteloua curtipendula). Park managers added forbs in 1976 and made subsequent additions of forbs and Canada wild rye in 1992 and 1994. In 1997, a small tree planting (approximately 2 acres) was created on the southeast ridge of the prairie. Only a few oaks remain in this planting. In 2000, the park planted 200 nut trees immediately south and west of the Gravesite and survival is estimated at about 50 trees. Other wooded areas occur within the riparian area and on the edges of the prairie. These are dominated by black walnut, green ash, and hackberry (Celtis occidentalis), and several invasive trees and shrubs.
