Spatial patterns of range management and fodder resources: how important is local reserve biomass ?

摘要：

A sustainable range management has to cope with the temporal variability of natural resources,but also to spatial variability both on local and a landscape level ( Linstadter and Bolten,2007).As regards the natural resource.fodder,range management has to ensure fodder reserves as an ecological buffer against temporal variability,and it has to be adapted to spatial differences in vegetation productivity and recovery potential of plants (Müller et al.,2007).Fodder reserves are crucial for two key situations : firstly for scarce times within the annual grazing cycle,and secondly for drought times.Different user groups may have alternative strategies ensuring the availability of fodder reserves on local and regional levels.They may either be ensured on a local level as reserve biomass of perennial species,and/or as protected reserves for drought.It may also be obtained on landscape level through external (non‐local) resources,either by moving livestock to external pastures,or by fodder supply.
