BIO Point Center Sampling: Species Specific Computations Use the instructions below and/or in the Powerpoint to complet the computations. You will be determining relative frequency (species composition). Species # of Trees Relative Density (%) Density # Points Frequency of tree species in sample Relative Frequency (%) Sweet gum 4 Hornbeam 3 Loblolly 2 Elm 3 Cypress 2 Beech 2 Hickory 1 White Oak 2 Water Oak 1 Species Specific Computations: Relative Density = Number of individuals of a species/total number of individual trees sampled Density = (Relative Density/100) x Tree Density from Table 2 This calculates the number of trees of this species per hectare. # of points = Number of sampling points (maximum of 5) Frequency = number of sampling points in which at least 1 tree of this species was present/total # of points Relative Frequency = Frequency/sum of all frequency values for ALL species x 100
