Temporal and spatial patterns of vegetation change were recorded in the Lawrence Succession Strips at Cedar Creek. Each year since 1974, a 120 by 20m strip of the cultivated rye field on the study site has been left undisturbed following two years of repeated preparation disking. The strips are abandoned sequentially. Frequency sampling has been performed in nine different years by recording each species' presence in 25, 20 by 20cm units in each of 40, 1 m2 quadrats per strip. Species' percent cover was recorded in late July from 1983 through 1987. This portion of E096 was conducted by B. Delaney. Starting in 1988, all trees in the Lawrence strips were tagged with prestamped aluminum tags, measured (maximum vertical height in cm), and mapped. Mapping: 2 aluminum stakes were put along the boundary between each strip, 1 at 20m from the woods, 1 at 40m from the woods. These stakes divide each strip into 3 sections: 1)the 20m closest to the woods (west side of field), 2)the next 20m and 3)the rest of the strip (towards the road). Trees are mapped by measuring the distance from the tree to the closest stake on each side of the strip. Trees in section 1 are mapped from the two stakes, one on each side of the strip, that are closest to the woods. Trees in section 2 are mapped from the same two stakes. Trees in section 3 are mapped from the two stakes that are farthest from the woods. Trees were measured in 1988, 1989, and 1990. New seedlings and untagged trees were tagged each year. From 1991 through 1997 trees were measured and browse condition was recorded. This portion of E096 was conducted by R. Inouye.
