“…Commonly used slope stability models such as SHALSTAB (Montgomery and Dietrich, ) and SINMAP (Pack et al ., ) extrapolate an average or uniform distribution of point measurements to estimate cohesion. Others have used the size, geometry and distribution of different trees within a stand to estimate local minima in root strength (Roering et al ., ; Sakals and Sidle, ; Cislaghi et al ., ; Temgoua et al ., ). Alternatively, remotely sensed metrics of vegetation, such as normalized density vegetation index (NDVI) and light detection and ranging (LiDAR)‐derived canopy heights, have also been related to root reinforcement (Chiang and Chang, ; Hwang et al ., ).…”
