Abstract

Such kind of human necessities restructured the
existing landscape pattern which brings imbalance in regional biodiversity.
Radhanagar Forest Range (RFR) in Bankura district has been faced same kind of
activates since 1960. As a result, forest patch becomes isolated and
structurally complex in nature which is an important cause for extinction of
wild animal. To control this damage forest department increased forest area
through several plantation schemes in vacant or barren land.  But plantation areas were not appropriate in
the question of structural forest quality in this region. The present study
seems that forest structural quality is a vital consideration for balancing
biodiversity, in concern of several ecological processes like species movement,
connectivity, colonization and edge contrast. Suitable forest patch structure may
possible when appropriate areas i.e. forest encroached areas will be select for
plantation. To prove this statement, study considers two types of landuse
alteration into forest land i) all barren land altered into forest and ii)
selected encroached areas altered into forest land  in RFR. ArcGIS 10.3 version software is used for
technical map editing and preparing these spatial alteration maps. After that several
landscape ecological indexes like Total Core Area Index (TCAI), Mean Core Area (MCA)
at 300 m specified edge depth, Total Edge (TE), Edge Density (ED), Area
Weighted Mean Shape Index (AWMSI), Area Weighted Mean Patch Fractal Dimension
(AWMPFD) and Mean Patch Size (MPS) are calculated using FragStat 4.2 version
software to compare both spatial alteration forest qualities. Comparison analysis
explains that encroached areas alteration into forest land is qualitative to
improve forest structural quality. It is interesting to know that less area
will be planted in encroached area to get utmost forest structural qualities.
