Park Species Detail: Gounaris, 2000: Characterized by medium invasiveness, while covering a relatively low percentage of the park. Specific populations of bamboo may need to be prioritized. A single, relatively small population near the glasshouse on Jamestown Island is small and may be more manageable. However, three populations in Yorktown are large, dense, and highly visible and are responsible for stabilizing the soil they are growing on. These populations should be a lower priority due to the expense and resources involved in removal and re-vegetation, though even smaller sites are like to require some re-vegetation. Yorktown: Eleven* populations were found lining steep slopes, within roadside (~2 acres) and in areas of past or present development. Eight of the II populations are extremely mature with many large individuals. Jamestown: Nine small populations* were found along roadsides (~4 acres). Most individuals have not yet reached two meters in height. One mature population was found near the glasshouse and Jamestown entrance road. Colonial Parkway: Twenty small concentrations were found within ~ 18 acres of the parkway corridor * Neck of Land: One large population was found in old homesite area. * It is likely that populations recorded as being immature or "small" are actually populations of native cane Arundinaria sp., which was initially confused with bamboo in surveys. Identity of populations should be confirmed before mitigation actions are taken., Park Species Data Source: Hobson, 1998-Yorktown Unit/ Cheatham and Wormley Pond Drainages;Gounaris, 2000 -Colonial Parkway/Jamestown Unit/Yorktown Unit;Clark, 1998-Colonial Parkway/Jamestown Unit/Yorktown Unit;
