B, Swai'd of Bouteloua curtipendula with Ranunculus fascicularis on top of a limestone cliffabove an old channel at Healey Falls. The trees are Juniperus virginiana and Quercus macrocarpa. native species were recorded. Many of these were confined to one of the three major vegetation types: savanna, prairie and sand barren. However, a few species occurred in all, or almost all sites (Appendix Table 1). Included in this group were Long-fruited Anemone (Anemone cylindrica). Sedge {Carex sic- cata), Sedge {Carex pensylvanica). New Jersey Tea {Ceonothus americanus). Grey Dogwood {Cornus racemosa), Canada Blue Grass {Poa compressa) and Kentucky Blue Grass (Poa pratensis). Cornus racemosa, Carex siccata, Carex pensyl- vanica and Snowberry (Symphoricarpos albus) (in order of descending cover values) were dominants on Hastings Savanna, while at Glen Miller Savanna (Figure 4a) Symphoricarpos albus comprised most of the cover, followed by Fragrant Sumac (Rhus aro- matica), Carex pensylvanica. Northern Bedstraw (Galium boreale). Woodland Sunflower (Helianthus divaricatus) and Cornus racemosa. Although these sites had some dominants in common, they differed considerably in composition (Appendix Tables 2 and 3). Carex pensylvanica, Cornus racemosa and Symphoricarpos albus have their highest percentage frequency and percentage cover on the savannas (Appendix Tables 2 and 3). Species unique to the savannas include Grove Sandwort (Arenaria lateri- flora). Large-leaved Aster (Aster macrophyllus). Cooper's Milk-vetch (Astragalus neglectus), Canada Brome (Bromus pubescens), sedges (Carex cephalophora, Carex rosea, and Carex umbellata), Robin's-plantain (Erigeron pulchelhis), Galium boreale.
