Evaluation and Comparison of Mixed Tree Plantation Performance Using Survival-growth Index Formula

Rajdeep and Prafulla Soni

Plantation of different tree species with different purpose is an old time practice. Scope of plantation has been improving with the development of silviculture practice, agro-forestry and all other industrial sectors that depend on the trees. Measurement of growth and survival seems the very first step for every type of plantation measurement for their performance, suitability and productivity. It is found that for every tree species height and diameter profile varies from site to site, climatic factors and for other conditions. The survival of individuals also varies in every case. In such cases, if we measure the growth dimensions of a tree species with the survival then it becomes very confusable or tough to state that which plantation or what species is performing better. These questions become even more difficult in cases of mixed plantation. Hence, a simple formulation of ‘Survival growth index’ is presented in this article to describe the performance of the tree plantation stands. This ‘Survival growth index’ is found very useful to evaluate the performance of a plantation whether it is a single species or a mixed plantation. The evaluated value of SGI for a plantation of specific age can state its performance using height and diameter profile with the survival percentage.
