In order to improve and maximize biodiversity due to time restrictions, finance resource limitations to protect all habitats, species, and also due to people increasing concerns about biodiversity decline, it’s required that before any protective action, basic programs, management programs, political decision making, a rapid assessment and priority assigned about habitats and species threat. This research aims to assess biodiversity threats in Jajrood protection complex, provide threatened status delineation as cellular-network in the area. In order to analyze biodiversity threatened fast evaluation in Jajrood protected area, initially biodiversity’s threats rapid assessment criteria and sub-criteria identified through reviewing various resources, then sub-criteria presence in the area was studied and 47 biodiversity threaten Sub-criteria identified in two fields of ecology and social economy. Then the most important sub-criteria were selected through using TOPSIS method. Sub-criteria selected through quantification-based indices were studied in order to classify biodiversity threatened status in studied area. Finally, biodiversity threatened status classified as cellular-network in Jajrood protected area in five critical classification: high threatened or endanger, mild threatened or vulnerable, low threatened or very low threatened. Based on the results, 39.46% of area was in critical zone, 59.83% in too much threaten, 0.12% in vulnerable zone and only 0.59% of whole area was placed in very low threaten zone. The results emphasis the efficiency of this model to be applied in protected area as a rapid assessment method.
