| - ;__Species Density Estimates (D)__: This set of operations was discussed in the paper (Gross et al. 1999). They define D as the measured or estimated number of species per m^2. And give a number of methods for estimating D from data sets. Each method is accompanied by a citation. The methods are: |
| - ** Percent cover from smaller plots (Inouye et al. 1987, Inouye 1998) |
| - ** ANPP (annual primary productivity) harvested plots (Huberty et al. 1998) |
| - ** ANPP harvested plots, combined for a transect estimate of D (Milchunas et al. 1990, Inouye 1998) |
| - ** Percent cover adjacent to ANPP plots, interopolated for a per m^2 transect estimate of D (Briggs and Knapp 1995) |
| - ** Censused in m^2 plots containing smaller quadrats used for ANPP estimates (Shaver 1986, Chapin et al. 1995) |
| - ** Species presence censused at 200 points in each m^2 plot sampled for ANPP (Walker et al. 1994) |
