Park Species Detail: Gounaris, 2000: One of the species causing the greatest impact, based on the parkwide acreage they cover. Complete control of these species throughout the park will be difficult and costly. Therefore, specific populations or areas of the park should be considered for management of these species. Characterized by mediium invasiveness, while covering a relatively high percentage of the park. Yorktown: Two small populations were found in a regenerating old-field habitat a short distance from the west tour road. Also found within 23 fields and -75 acres of roadside; Jamestown: Found within-16 acres of roadside; Green Spring: Found within <I acre of roadside; Colonial Parkway: Found within -601 acres of parkway corridor. /Van Alstine, 2001: Pond 44, Pond 45./, Park Species Data Source: Loetterle, 1970-Jamestown Unit /Jamestown Island;Salle,1972-Colonial Parkway;Gounaris, 2000 -Colonial Parkway/Jamestown Unit/Yorktown Unit;Van Alstine, 2001-Yorktown Unit/Depression Ponds;Chazal, 2001-Jamestown Unit /Jamestown Island
