A New Index of Spatial Clustering for 1 Dimension Data
Transect sampling is a common field method in ecology. Researchers favour two-dimensional trapping grids or webs but managers tend to favour one-dimensional line transects because of their practical advantages: they provide speedy (although low-intensity) sampling of large areas of terrain, are straightforward to establish and relocate, and minimise repeat travel, trampling and disturbance of habitat. Given the wide-spread use of this type of sampling we have developed a common-sense index of spatial clustering for transect data. The index is a modification of the SADIE method where information on the spatial location is used to measure clustering.
