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)
