In this research video, we explore the results of Tom Mackay-Smith's PhD at Massey University, measuring the impact of spaced kānuka trees on surface runoff and sediment and nutrient losses in New Zealand hill country.
Results of this project include:
Significantly more surface runoff under the trees.
Likely a response of livestock preferentially grazing the pasture under the trees.
