• Abstract:

  Forests recovering from agricultural legacies differ in many ways that influence tree seed dispersal and seedling establishment patterns. We recorded the number of seedlings (less than 0.5 m tall) of all tree species on a 1 x 1 m resolution across six land use legacy sites (2 plowed, 2 pastured, 2 permanent woodlot) in summer 1996 to test several predictions about seedling abundance, diversity, and dispersion patterns, and their relationships to forest structure, microclimates, and soil resources.

• Methods:

  Plot locations: Plow #1 Site: Prospect Hill Tract, Compartment # III, southern end. Plow #2 Site: Prospect Hill Tract, Compartment # III, southern end. Pasture #1 Site: Prospect Hill Tract, Compartment # I, southeastern edge. Pasture #2 Site: Prospect Hill Tract, Compartment # VIII, central edge. Woodlot #1 Site: Prospect Hill Tract, Compartment # VIII, northeastern edge. Woodlot #2 Site: Prospect Hill Tract, Compartment # VII, central.

Detailed Metadata

hf141-01: tree seedlings

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.
4. number: number. Each cell has a unique number (1 through 1500) for use in digitized mapping of tree counts. 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: x-coordinate of cell center for digital mapping of seedling counts across the grid (unit: meter / missing value: NA)
6. y: y-coordinate of cell center for digital mapping of seedling counts across the grid (unit: meter / missing value: NA)
7. species: species
8. count: counts of seedlings in each 1 x 1 m cell by species (unit: number / missing value: NA)
