• Abstract:

  Forests recovering from agricultural legacies differ in many ways that influence the landscape distribution, local abundance, and dispersion of herbaceous populations, as well as patterns of species associations within the herbaceous stratum. We recorded the presence/absence of 10 herbaceous species on a 1 x 1 m resolution in a 30 x 50 m permanent plot grid in six land use legacy sites (2 plowed, 2 pastured, 2 permanent woodlot) in summer 1996 to test predictions about herbaceous species abundance, richness, dispersion patterns, patterns of association, and their relationships to forest structure, microclimates, and soil resources. The 10 species chosen differed in several ways (evergreen vs. deciduous, stature, clonal architecture, affinity for disturbed vs. undisturbed forests) that allowed us to probe the impacts of prior disturbance and current resource patterns (light, water, nutrients) on the spatial patterns of individual species and species associations.

• Methods:

Detailed Metadata

hf136-01: herbaceous species

1. Site: site
   • P1: plow 1
   • P2: plow 2
   • S1: pasture 1
   • S2: pasture 2
   • W1: woodlot 1
   • W2: woodlot 2
2. Plot: Plot number. Each permanent 30 x 50 m grid has 60 5 x 5 m plots. They are numbered from left to right and top to bottom across the grid. The upper left corner plot is 1 and the lower right corner plots is 60.
3. Cell: cell number. There are 25 1 x 1 m cells within each plot, also numbered left to right and top to bottom. The entire grid has 1500 1 x 1 m cells. All six sites are included in this archived file, for a total of 9000 records.
4. Number: number. Each cell has a unique number (1 through 1500) for use in digitized mapping of herb patterns. The cell numbers are assigned by grid row, with numbers 1-30 across the top row of the entire grid, cells 31-60 across the second row, etc.
5. X: cell center X coordinate for digital mapping of herbs across the grid (meter )
6. Y: cell center Y coordinate for digital mapping of herbs across the grid (meter )
