COMPARATIVE STUDY OF GROWTH RATE EVALUATION FOR ASH (Frasinus excelsior) IN SOUTHEASTERN ROMANIA
Abstract
At present, the monitoring of forest areas is a national requirement. The importance of protecting forests in mitigating climate change is well known. On the other hand, the economic aspects involving the efficiency of forest management imply correlation with the growing demand for wood on the market. From this point of view, the inventory and the evaluation of the rate of growth and yield of forest areas is extremely important. Estimating the growth rate per unit of hectare and the level of production of wooded areas for accurate obtaining and inventory is important in determining the supply of wood. The present paper is based on the evaluation of six ash (F. excelsior) growth seasons. The monitored sectors are located along areas with a relatively low altitude (280-450 m). The climatic gradient can also be neglected due to the nature of the studied areas. The research was conducted in the south-eastern part of Romania. The timeframe in which the study was conducted ranged from 2010 to 2015. Technological factors such as consistency, density, etc. were carefully assessed based on observations and field measurements in the field. The results obtained through numerical approaches have shown that: (1) estimates of the growth rate can vary significantly when using different statistical and numerical methods; (2) using numerical optimization models, computer simulations can provide accurate estimates of the growth rate and hence the effectiveness of a given forest inventory; (3) common methods of numerical interpolation or uses of neural networks that do not always yield acceptable results.
