Tree spatial pattern in secondary tropical forest - study within the SAFE Project led by European scientists in Borneo

This study, conducted in secondary tropical rainforest in Sabah, Malaysia, is based on data collection using FieldMap technology. All positions of trees (DBH bigger 1 cm) and other attributes were recorded within 24 research plots (25 x 25 m). The aim of this study is to determine any deviation from a random arrangement of trees and nonrandom spatial structures in tree mortality using second order statistics (pair correlation function). All analyses were carried out with the comprehensive software package for conducting spatial point pattern analysis, Programita (developed by Wiegand 2012).
