Stan Braaksma

After a lifetime of Land Management services to the Greater Wellington Region, retirement beckons. I still maintain strong links with past clients and the farming industry. My experience covers a broad spectrum, of Land and Riparian issues over most of NZ, and has extended into the management of tree species, for protection, production, erosion control and longevity. Poplars and Willows have been a crucial tool in minimizing erosion on hill country. I have long been associated with selecting for improved clonal performance. “Right tree in the Right place”. As Team Leader to Akura Nursery, I was part of refining management to produce healthy, well graded pole material.
