Forest science or forestry evolved from botany and named Dendrology or Xylology being dominated by trees or woods also grouped under forestry or higher plant taxonomy. Many literature put these terminology interchangeably but as I know plant taxonomy is general mainly with certain classification basis mainly flowers which is plant classification but dendrology with specific to trees so not also forestry as such. Dendrology is part of botany or forestry where we study the different aspects of trees from classification, ecology, cultivation to utilisation OR Dendrology is just to know how to identify the trees or woods with help of plant taxonomy, other morphological, anatomic features. Then what will Wood anatomy and Wood Science do?? Please share your views.
