Abstract

Random forcing due to the river streamflow is a key element in riparian vegetation ecosystems. It influences several aspects of the riparian landscape, the most important being the morphology and water availability. In this letter, we analytically solve a stochastic model to show how hydrological random fluctuations are able to induce both statistically stable states and bimodality in vegetation behavior. These noise‐induced results can contribute to explain two well‐documented features of several riparian landscapes: the bell‐shaped biomass distribution along riparian transects, and spatial vegetation patchiness along a river.
