This paper highlights the importance for dating accuracy of initial studies of delay before colonization for both trees and lichens and tree age below core height, particularly in recently deglaciated terrain where colonization and growth rates may vary widely due to differences in micro-environment. It demonstrates, for the first time, how dendrochronology and lichenometry can be used together in...
Over the last 50 years, frequent debris flows on the oversteepened slopes crossed by the main A5 road in Nant Ffrancon, North Wales, have presented a significant traffic hazard. This study uses two approaches to lichenometry to date earlier debris flows. The first approach provides dating estimates based on size/age correlations of the lichen Rhizocarpon geographicum subspecies prospectans growing...
