Description

Marked point patterns of two consecutive cohorts of seedlings of H. squamatum growing in a gypsophylous plant community in Central Spain. The datasets contains the locations of the seedlings marked with their heigth. Both the coordinates and the heigth of the seedlings are given in cm.

Usage
