Abstract

Soil and vegetation are interacting factors controlling erosion. Soil degradation processes may affect the normal
tree and shrub development and inversely, vegetation can modulate the velocity and intensity of soil development
or denudation. A dendrogeomorphological approach can be used to study these interactions, allowing to
obtain a date and estimate mean or specific erosion rates. This is especially useful in an unrecorded badlands
and gullied environments,where the scarce vegetationmay be the only proxy available to quantify the different
geomorphic processes which have occurred. This paper provides a fundamental review of the
dendrogeomorphological methodology applied to erosion measurement in badlands. Focusing on the response
of the vegetation to the geomorphic processes, this paper: (a) describes themethodology developed to estimate
erosion rates with exposed roots; (b) shows newadvances through case studies; and finally, (c) discusses future
lines of research to reduce methodological uncertainties and for making dendrogeomorphology more widely
applicable.
