Resumen
The goal of this study was to propose scientific and objective indices capable of measuring
the changes that occur in the conservation status of the vegetation of a particular area over a period
of time. To this end, phytosociologically-based vegetation cartography at a detailed scale was
used, carried out at two di erent times, and the distance from the climax stage of the territory was
calculated for each time. Three temporal indices of landscape change are proposed: Conservation
Status Variation Index (ConSVI), Conservation Status Variation Velocity Index (ConSVVe) and Change
Ratio (ChanRat). These enable the intensity, velocity, and percentage of change to be measured, and to
determine whether this change is progressive or regressive—in other words, whether it is approaching
or receding from the climax. To test the proposal, it was applied to a territory in Northwest Spain.
The proposed indices are universally applicable to any territory and are the first of their kind to
operate at a detailed scale with a phytosociological basis. They also enable an objective measurement
to be made of the landscape change that has occurred, meaning that they have immense practical
utility in studies of managing and planning territorial resources.
