112 Change Detection of Land Cover and Landscape Spatial Patterns Changes in Arasbaran Biosphere Reserve for Developing Co Management Programs Asef darvishi Asef darvishi@yahoo com Supervisor Sima Fakheran Alireza Soffianian Department Natural Resources Engineering Isfahan Univesity of Technology Isfahan 84156 83111 Iran Degree M Sc Date of Submition 2014 01 22 Language PersianAbstractLarge scale land use cover changes and habitat fragmentation have been associated with the declineof many wildlife populations in ecological sensitive regions Because natural habitats are affectedby various and shifting social and ecological variables one of the challenges stems from the factthat sustainable management systems must relate and adjust to a complex and ever changingenvironment The concept of adaptive management addresses this desirable quality by monitoringand adjusting in accordance with what is known about the socio ecological environment The maingoal of this study was to quantify the spatial pattern change in Arasbaran Biosphere Reserve Northwest of Iran in two periods of 14 years 1987 2001 and 10 years 2001 2011 and toaddress the social network structures for developing an adaptive management strategy in Arasbaranbiosphere reserve Arasbaran is one of the most important protected areas in Iran becauseCaucasian black grouse Tetrao mlokosiewiczi is only restricted to the Arasbaran BiosphereReserve in Iran and the population and range of this specialist bird species have been decliningover the last decades Up to now most of the studies have focused on local factors to explainCaucasian black grouse population trends However larger scale landscape patterns changes mayhave contributed to the declines This study focuses on the landscape structure changes of blackgrouse habitat We used Landsat Thematic Mapper TM satellite image from 1987 2011 andETM from 2011 for analysis of the spatial pattern of the species distribution polygons Thesatellite images were geometrically corrected and classified for quantifying landscape patternchange various landscape metrics were derived from spatial analysis software FRAGSTATS including PLAND Percentage of Landscape ED Edge Density NP Number of Patches andLPI Largest Patch Index TE Total Edge and LSI Landscape Shape Index In addition weconducted a comparative case study of two villages Kalale and Kharill in the study area forsocial ecological systems analysis In this study by fieldworks cooperative observation andorganized interview target groups were recognized and then main social criteria of naturalresources co management including trust collaboration social cohesion and social capital wereidentified In level of natural resource users as social partners of natural resource co management interpersonal trust links collaboration kinship and neighborhood were investigated The resultsindicated that during the last 24 years 1987 2011 the proportion of forest was significantlydecreased by 12 3 while grassland 5 4 astragalus 3 7 sparse forest 1 and bare land 4 9 were increased in the study area Largest patch index LPI also decreased in dense forestsin the second period which revealed fragmentation of forests to small patches in the Caucasianblack grouse habitat Number of Patches of forests was increased in the first period and decreasedin the second period that shows fragmentation of forests in the first period 1987 2001 and loss ofsmall patches in the second period 2001 2011 The results of users networks analyze of Kalaleand Kharill villages showed users network in Kharill village have high social cohesion degree incomparison with Kalale users network and some actors of the network have higher social powerand social capital than other villagers In the highest level of users collaboration and neighborhoodlinks have significant and high correlation The results of social network analysis revealed thatnatural resource co management strategy could be more successful in Kharill village The results ofthis study
