Offered Papers Theme B: Grassland and the Environment
Description
Early warning systems that depend on the selection of suitable indicators of thresholds are useful (Friedel, 1991). An ideal indicator should be unbiased, sensitive to changes, predictive, referenced to threshold values, data transformable, integrative and easy to collect and communicate (Liverman et al., 1988). Methods for selection of indicators for assessing ecosystem health are being developed (Pyke et al., 2002). This paper examines the situation in grassland vegetation grazed by sheep in a semi arid region of northeastern Iran.
