Quantifying the effectiveness of trees in reducing erosion and sediment delivery

This project was led by Raphael Spiekermann while at Manaaki Whenua - Landcare Research

It explored the findings of Raphael Spiekermann's PhD research that quantified the effects of different tree species on slope stability using geospatial models.

Results of this project include:

  • High disconnection between where landslides occur and where poplar and willows are growing in the study site.

  • Targeted planting dramatically increases the cost-effectiveness of space-planting.
