McAlpine, K. G.; Drake, D. R. 2003. The effects of small-scale environmental heterogeneity on seed germination in experimental treefall gaps in New Zealand. Plant Ecology 165: 207–215.
Seed germination of native and exotic woody species was studied in treefall gaps to assess how environmental heterogeneity affects regeneration from seed. Gaps were created in a relictual pine plantation destined for restoration to native forest. Seeds of Alectryon excelsus, Macropiper excelsum, Fuchsia excorticata, Cytisus scoparius and Berberis darwinii were sown in sites differing in exposure, with and without 3 cm of pine litter. Effects of litter and degree of exposure on germination varied with species. Results suggest that microenvironmental heterogeneity can be an important influence on the species composition of regenerating vegetation within and around treefall gaps.
