Prairie Inventory Herbert Hoover National Historic Site 1997
Christiansen P. 1998. Prairie Inventory Herbert Hoover National Historic Site 1997
The reconstructed prairie at Herbert Hoover National Historic Site in West Branch, Iowa, has been the site of an extensive prairie inventory since 1982. Both walking transects and permanent plots were sampled in 1982 and annually since 1984. During this time the practice of removing accumulated litter by haying has been replaced by prescribed burning and selective brush and weed cutting. In 1992 more than 160 prairie forb plants were labeled by staking and their location identified with coordinates in a grid system. Since that time new recruits have been parked and dead plants noted. Flowering of individual plants has also been noted each season. Each yearly inventory has informed resource managers in the techniques likely to enhance the prairie vegetation. This report contributes to that reservoir of information, especially in the establishment scenario of the new seedings of 1992 and 1994, persistence and flowering of various forb species, as well as cover and persistence information of the established prairie.
