at vegetation on the north-south transect of the Peterborough drumlin field. Only a small part of this drumlin retains natural vegetation, the rest is roads and farmers fields. The trees are generally deciduous, and a patch of white birch occupies the forest. The coniferous trees are sporadic and young, amongst tall grasses and shrubs. The litter layer of the forest is quite deep, adding to the high interception rate of the forest.The drumlin on the border of Rice Lake yields evidence of grazing by live stock. Fecal matter covers the hillside and the excavated section of the drumlin and both areas show signs of compaction by trampling. Pine and maple trees dominate the area with some oak trees, vines, and tamaracks. This area, as with most of Ontario, has probably been logged at least once. Part III: Warsaw CavesThe vegetation at the Warsaw Caves was indicative of an area with exposed and weathered limestone bedrock. Cedar trees were the most prominent trees and because their spatial dispersion and foliage is dense, little undergrowth was present. Poison ivy grows in patches throughout the forest along with thick moss cover. The most noticeable change in vegetation occurs on the eastern side of the Indian River. Instead of evergreens, there was dense deciduous vegetation. Observations concluded that there is a greater amount of deposits in some places along the eastern side of the river, which are favourable to deciduous vegetation. Part IV: Comparisons of Sites and Previous LiteratureForests in the Peterborough region vary distinctly depending, largely, on the local features and geology. All of the tree types identified in the field were supported by Barnes (1965, p.84) and he indicated the importance of local climate, soil, topographic and drainage features influencing tree species in an area. The Otonabee Region Conservation Report (1983, p.5-i) states that “most of the trees are immature, with only eight percen...
