Les Basher

Dr Les Basher is a Research Associate with Manaaki Whenua – Landcare Research. I retired from full time employment in 2020 after a 43 year career starting in Ministry of Works Water & Soil Division and ending with MWLR. My research interests spanned soil science and geomorphology, with a main focus on erosion and sediment processes across all land uses and in all areas of New Zealand.

My expertise and publications span the full range from process understanding to model development and application. I led the work that resulted in the current version of the Erosion Susceptibility Classification that is one of the key tools in the NES for Commercial Forestry, and have been an advocate for a science-based risk management approach to better manage the effects of forestry in erodible steeplands. I continue to provide consultant services in erosion and sediment processes and soil science, and am involved in the current paired catchment study in Tasman District aiming to improve post-harvest sediment management.
