I have ecological data of Abies pindrow and i want to check the regeneration pattern of this plant species. I want to apply size class distribution method for this study. Kindly let me know the methods according to the same.
You can use plot sizes of 25 × 20 m in different areas (replicates). You can measure diameter at breast height (DBH), species composition, regeneration potentials (density of seedlings, saplings and poles) and number of individual trees per hectare (density). Saplings are young trees with diameter of 2 to 6 cm and seedlings are those with diameter < 2 cm or height < 30 cm.
