Tree identification & Tree Damage

Tree identification – As uncovered by Carl Linnaeus, through observation and the scientifice methodology,  you need to go through a logical identification process of characteristics  as follows:  Bark, leaf arrangements, leaf shape, leaf margin and texture, Flower, Seed and Fruit, Habit – If you are doing a dissertation and you are not sure of the scientific methodology study trees and Linnaeus and all will become clear

Tree Damage – Risk of Damage by different tree species – the table indicates (click here) that the extent and depth of drying around oak trees can be significantly greater than occurs with most other species.

If damage occurs an expert should advise, with reference to BRE 298, action required
