“…al. 2016;Mandal & Chatterjee, 2018) and enhance physical core area of the same habitat (Begotti, Dos Santos Pacífico, de Barros Ferraz, & Galetti, 2018). After the alteration of some encroached area into the forest land, the shape complexity decreases in four large patches in RFR.…”

“…Therefore the edge of the forest habitat is sharp with a clear outline border. Habitat shape has now become more fragmented than before due to plantation in barren land and open area in the forest (Mandal & Chatterjee, 2018). It causes various ecological circumstances and creates species dispersal related activities.…”

“…Habitat shape structure controls several ecological processes like animal movement and colonization (Luque, Pastur, Echeverría, & Pacha, 2011). Forest interior species are much more sensitive to patch shape (Devictor, Julliard, & Jiguet, 2008) because it determines the amount of interior or core areas of the habitat (Mandal & Chatterjee, 2018). Therefore, habitat encroachment by other landuse intensifies both structural and ecological function of the landscape (Bogaert et al, 2008;Echeverría, Newton, Lara, Benayas, & Coomes, 2007).…”

“…Present landscape spatial information in Radhanagar forest range represents higher fragmentation with more patch shape complexity (Chatterjee, 2016;Mandal & Chatterjee, 2018). Forest fragmentation due to agricultural expansion and scatter plantation in barren land rapidly changed the forest shape and size in the entire district (Chatterjee, 2016).…”

“…This continuous process is damaging the quality of the entire forest habitat. As a result of it, core dependant species becomes extinct and multi habitat species movement becomes haphazard which rises the high risk of conflict in this region (Kulandaivel, 2010;Mandal & Chatterjee, 2018).…”

Anthropogenic pressures create a complex pattern of forest habitat shape structure in Radhanagar Forest Range (RFR) in Bankura district. Habitat landscape design controls existing bio-geographical process. High fragmented and more complex habitat make imbalance in ecological process in the study area. Therefore, a measure is very urgent to control fragmentation process. Spatial alteration is one of the best methods to improve habitat quality which reduces habitat shape complexity. Fragmentation and structural composition of habitat will be understood through the interpretation of several geometric indices like perimeter area ratio (PAR), shape index (SI), and fractal dimension (FD). These indices are used to know the nature of habitat fragmentation in Radhanagar Forest range. The main objective of the study is to reduce habitat shape complexity by spatial alteration. Therefore, two types of map, one is existing forest land cover and another is selected areas altered forest land cover of Radhanagar Forest Range are prepared using ERDAS 9.3 and ArcGIS 10.3 version software. Then these maps are analyzed through FragStat 4.2 version software to get above mentioned indices. The study compares the indices values to know the structural quality of forest shape from both maps. The comparison address that altered forest habitat structural quality is better than existing forest landscape habitat quality. Therefore, landuse alteration in a forest matrix is obviously area specific in respect of its shape structure. ARTICLE HISTORY
