During 1993 a floral and fauna inventory was conducted on the Palo Alto National Battlefield Historic Site . Vegetational associations were mapped, and the impacts of agriculture and ranching were assessed. Attention was given to identifying endangered, threatened, or candidate species present within the site boundaries, and also species which may have been extirpated. An attempt has been made to envision where historic roadways were located and how the 1846 landscape may have appeared.
