Ecological function as a criterion for the evaluation of conservation: The case of the river Dulce (Guadalajara, Spain)

Abstract

An ecological evaluation of the River Dulce was conducted, as part of the management plan of the whole basin of this river. Homogeneous sectors according to ecosystem structure and function were identified. Habitats along the river course were described and water quality evaluated, allowing the division of the river in scctors. Ecosystems usually considered of minor importance using faunal or landscape-aesthetic criteria, are assessed as being of high ecological value because of their function in the control of perturbations. © Asociación Española de Limnología.
