Systemic Management of Mountainous Rangeland Ecosystem, Case Study: The Javaherdeh Rangeland of Ramsar

Abstract

Mountainous rangeland ecosystems have a highly delicate position in ecologic area<br />because of severe environmental conditions and having wildlife and livestock. Knowing and<br />realizing the biotic and abiotic components, which have an interaction with each other in this<br />ecosystem, perform the most important role in to desirable management of it. The systematic<br />management is one of the managing features such as modern approach for land management<br />and suitable use of upland ecosystems. To reach that, mountainous rangelands of Javaherdeh<br />(Ramsar) via 1:25,000 scale map were selected. Density, rangeland conditions, vegetation<br />cover, gravel and grit were determined by Superficial and modified six-factor methods, Arc<br />GIS v.9.3 software was employed to achieve land form map which was obtained by the<br />combination of altitude, slope, and slope aspect maps. First, basic and first environmental unit<br />maps were changed with land form map into soil type map, and first basic map into<br />vegetation type map. The proposal map of systematic management of area was associated<br />with final environmental unit map into landuse map via their attribute table. The established<br />proposal map shows accurate position of different future land uses on the basis of current<br />ecological capabilities of areas. Around Javaherdeh village is suitable for extensive outdoor<br />recreation (7.59%) and appropriate for the grazing of livestock (62.22%). Some areas<br />(20.07%) also should be protected because of landslides and debris formation.
