New publication - wind and landslides (and yellow cedar) in southeast Alaska

An article that Adelaide Johnson and I put together was recently accepted into Geomorphology - in it we look at interactions between various wind regimes, yellow cedar decline (YCD), and landslide occurrence in southeast Alaska.  Basically, we wanted to know if wind exposure or YCD predispose a location to sliding.  This is facilitated by the fact that YCD has been mapped and wind patterns are fairly predictable, so we can build a spatially explicit wind exposure model (which had been done previously over part of the landscape by Kramer et al. 2001).  

Turns out that despite smaller scale studies hinting at an interaction, there wasn't a link at broad scales between YCD and slides.  This is probably because the same factors which predispose a location to YCD (waterlogged soils, for example) also promote sliding, and so the relationship was masked. 

There was a significant relationship with wind exposure though - higher wind exposure means more likelihood of sliding.  This correspondence was limited to steeper slopes, though, likely because it's only on steeper slopes that root stabilization is an important for hillslope stability.  At lower angles, it doesn't matter how hard it blows, you're just unlikely to slide period.  So there is a broad-scale, significant interaction between these disturbances, but it's spatially mediated.  A nice nuance.
