Table 2 The density measured as the level of occupancy in the four populations we studied and the corresponding parameters for the fractal and Poisson models

From: Implications of salep collection for the conservation of the Elder-flowered orchid (Dactylorhiza sambucina) in Epirus, Greece

  1. Also shown are the results of testing for an increase of occupancy with scale, that would indicate a Poisson pattern (uniformly spread throughout the landscape) by means of p-values
