Sugar maple, black cherry and ironwood are the dominant species of <br />tree seedlings, along with a smattering of other species (Table 3). Relativdy few ironwood and <br />black cherry ever become mature dominant trees, and there few oak seedlings, indicating that <br />sugar maple will become more dominant in the ftiture. Gooseberries (2-3 species which were not <br />differentiated) arc the most frequent native shrubs, and buckthorn is the most frequent non-native <br />shrub (Table 3). Twenty-four species of native herbs were noted in the field, 17 of which <br />occurred on the sample plots. Sedges (probably Carex pennsylvanica), wood anemone and Jack- <br />in-the-pu!pit are the most frequent herbs. The non-native herb garlic mustard is also found on 30 <br />of the 30 plots (Table 3).
