Establishment of protected areas (PA) has been one of the leading tools toward biodiversity conservation. Globally, these kinds of conservation interventions have given rise to increase in PAs as well as the need to empirically evaluate the impact of these PAs on forest cover. Few of these empirical evaluations have been geared towards comparison of pre and post policy intervention landscape. This paper provides a method to empirically evaluate such pre and post policy interventions by using a cellular automata-Markov model. This method is tested using remotely sensed data of Bannerghatta National park (BNP) and its surrounding, which have experienced various national level policy interventions (Indian National Forest Policy of 1988) and rapid land cover change between 1973 and 2007. The model constructs a hypothetical land cover scenario of BNP and its surroundings (1999 and 2007) in the absence of any policy intervention when in reality there has been a significant potential policy intervention effect. Results not only show the implication of national level policy changes on forest cover but also show the usefulness of our method in evaluating such conservation efforts.
