It is an indispensable document in the process of obtaining a permit for felling trees, assessing the impact of investments on the natural environment and valuation of areas. It is useful for obtaining the environmental consent decision and very important for the estimation of works. It is performed to determine the number of trees and shrubs interfering with the project and requiring felling or trimming.
