Fascinating trees
This is the blog of Henry Kuppen (1964), passionate Arboricultural Consultant with over 35 years of professional experience in managing trees in the urban environment. Director of Terra Nostra, Knowlegde Center for Trees and Soils. As accomplished public speaker, I share my knowledge by giving talks and workshops to other professionals around the world.
Almost daily I feel inspired by the appearance of trees and the flexibility of nature. My work is characterized by looking through the eyes of an enthusiast, making links with scientific knowledge and combining it with the capriciousness of practical experiences. This blog gives both professionals and tree enthusiasts an impression of how to look at trees in order to respect them more and understand them better.
