A state-and-transition model of Iberian dehesas based on spatial patterns

Jesus Caballero, Ángel M. Felicísimo, Elia Quirós Rosado


Aim of study: In this study a process based on a Geographic Information System (GIS) is proposed as a tool for analyzing the spatial structure of the Mediterranean dehesa ecosystem.

Area of study: Western Peninsular Spain.

Material and methods: The method allows a semi-quantitative “state and transitions” (S&T) net that provides original information derived from spatial patterns that cannot be obtained by other means.

Main results: This GIS analysis also supplies a spatial basis which complements the conceptual framework of vegetation series successional proposals. Moreover, the proposed method can be a useful tool for understanding landscape changes.

Research highlights: Our work proposes not only a descriptive model but also a methodology based on spatial metrics and topological relationships.

Keywords: geographic information systems; successional net; landscape management.

Abbreviations used: S&T: State and Transition; RFP: Regional Forest Plan.
