“…The loss of forest habitats and forest fragmentation have been extensively investigated in the last few decades [1]. Studies carried out at various scales show that forest fragmentation is critical for maintaining biodiversity levels [2][3][4] and that deforestation increases forest fragmentation by dissecting intact forest areas, isolating forest patches, and eliminating forest corridors [5][6][7][8][9][10][11][12][13][14][15][16][17][18]. The vast evidence that forest-cover decrease is linked to increasing forest fragmentation may lead to a belief that forest expansion, on the contrary, decreases forest fragmentation.…”

Understanding the causes and consequences of forest-fragmentation changes is critical for preserving various ecosystem services and to maintain biodiversity levels. We used long-term (1860s-2010s) and large-scale data on historical forest cover in the Polish Carpathians to identify the trajectories of forest fragmentation. Past forest cover was reconstructed for the 1860s, 1930s, 1970s and 2010s using historical maps and the contemporary national database of topographic objects. We analyzed forest-cover changes in 127 randomly selected circular test areas. Forest fragmentation was quantified with GuidosToolbox software using measures based on a landscape hypsometric curve (LHC). Despite a general increase in forest cover, forest fragmentation showed divergent trajectories: a decrease between the 1860s and 1930s (in 57% of test areas), and an increase between the 1930s and 1970s and between the 1970s and 2010s (in 58% and 72% of test areas, respectively). Although deforestation typically involves the increasing fragmentation of forest habitats, we found that forest expansion may not necessarily lead to more homogenous forested landscape, due to complex land-ownership and land-use legacy patterns. This is both a challenge and an opportunity for policy makers to tune policies in such a way as to maintain the desired fragmentation of forest habitats.

“…Thus, in the context of this study, it allowed to perform an analysis of images from different sensors (Landsat and Sentinel 2A). The results obtained provide sufficient evidence that satellite data and remote sensing are tools for mapping land cover transformations by providing spatially explicit information (Cabral and Lagos, 2017;Hagensiekera et al, 2017;Ramachandrana et al, 2018).…”

The Mono Transboundary Biosphere Reserve (RBTM) has significant resources but faces many threats that lead to habitat fragmentation and reduction of ecosystem services. This study, based on satellite image analysis and processing, was carried out to establish the baseline of land cover and land use status and to analyze their dynamics over the period 1986 to 2015. The baseline of land cover established six categories of land use including wetlands (45.11%), mosaic crops/fallow (25.99%), savannas (17.04%), plantation (5.50%), agglomeration/bare soil (4.38%) and dense forest (1.98%). The analysis of land use dynamics showed a regression for wetlands (-23%), savannas (-16.06%) and dense forest (-7.60%). On the contrary, occupations such as mosaic crops/fallow land, urban agglomerations/bare soil and plantation increase in area estimated at respectively 128.64%, 93.94% and 45.23%. These results are of interest to stakeholders who assess decisions affecting the use of natural resources and provide environmental information essential for applications ranging from land-use planning, forest cover monitoring and the production of environmental statistics.Keywords: Land use, baseline, spatial dynamics, environmental statistics, ecological monitoring.

“…Surging population in India is expected grow till 2050 [32]. The Eastern Ghats alone in the Deccan Peninsula has undergone 40% reduction in forest cover between 1920–2015 [33] and the human population is predicted increase in the region [34]. Twelve out of 27 sites with YTB occurrence recorded by us had religious tourism.…”

12Yellow-throated Bulbul, Pycnonotus xantholaemus is an endemic, rare and threatened species 13 with discontinuous distribution across Deccan peninsula. IUCN has enlisted surveys for 14 newer populations as one of the conservation measures. We used maxent algorithm to 15 generate environmental niche model for further surveys. We looked into climatic envelope at 16 occurrence points and contrast it with background climatic envelope. We compared the 17 model for current scenario and future scenario to assess change in extent of predicted niche 18 over time. We used six variables: climatic, topographical and vegetation layers, and a final 19 set of 102 verified presence locations to generate the model. Topographic ruggedness index 20 and precipitation of wettest month (Bio13) were the strong predictors for Yellow-throated 2 21Bulbul niche. Model predicts highly discontinuous and small fragments totalling 7% area of 22 peninsular India as suitable niche. Only 10 % of predicted niche falls within India's protected 23 area network. Loss of habitat due to granite quarrying and anthropogenic pressure will be a 24 bigger threat than climate change. 25
