KILMER ECOLOGICAL PRESERVE NOTES STATION 1: POWERLINE CUT This is an example of early secondary succession. Annual species typical of this stage might include Foxtail Grass & Peppergrass & Ragweed. Many of these plants may come from seed banks , where viable seeds present in the soil (sometimes for years) germinate when the time is right (often after a disturbance). Perennial species in this area might include Cinquefoil, Plantain, Strawberry & Dogbane. Some of these plants may exhibit a low-growing rosette of leaves, which allows them to avoid wind in open areas. STATION 2: 1929 OLD FIELD A more advanced stage of secondary succession is observed here. Different plants use different dispersal strategies (i.e. spread their seed). Little Bluestem is a grass, so it is wind dispersed. Cedar has blue berries, so it is bird/animal dispersed. Maple has “helicopter type seeds” which are wind dispersed. Oaks have acorns, dispersed by birds and animals. You will still see plants like Little Bluestem here in this phase of succession because enough light still reaches the ground. Eventually they will disappear as the ground becomes more shaded. STATION 3: SIDE TRAIL AND LATER SUCCESSIONAL STATE IN 1929 FIELD This area is characterized by more trees and less herbaceous plants. Poison ivy produces low quality fruits dispersed by birds . STATION 4: MIXED STAND OF WOODY SPECIES OF LATER SUCCESSION This is a progressively later stage of secondary succession known as secondary growth forest. Trees typical of this area are Red Maple, White Birch, and Pin Oak. Woody shrubs are now starting to be shaded out. STATION 5: RED MAPLE GROVE This is a moist area, preferred by Red Maples. Most are the same height and diameter because they are the same age, suggesting that the seeds all sprouted together following disturbance. STATION 6: CLEARING
