“…Forest loss can lead to reduced species diversity (Hill and Curran, 2001), while configurational changes have been linked to increased wildlife-vehicle collisions (Gonser et al, 2009). Separating the components of loss and configurational change is difficult given that, in general, configurational change is driven by some form of habitat (e.g., forest) loss.…”

“…During the past several years, large complexes of natural habitat have been converted into agricultural, industrial, or urbanized landscapes, leading to severe loss of the original habitat and an increasing fragmentation of the remnant patches [4]. High fragmentation rate stimulate habitat modifications and the loss of valuable portions of the forest ecosystem, the number of rare and shade -tolerant species increases due to fragmentation especially during recovery at the early successional stage [5]. Tree species with small population will be the first to be lost in the process of forest fragmentation [6].…”

Ecological implications for the conservation of fragmented forests to managed local plant diversity have recently drawn much attention of most conservationists. Present study investigates the importance of fragmented forests using different quantitative measures of species diversity and stand structure as indicators of natural restoration from past disturbances. Eleven independent 500 m × 10 m belt transects (5.5 ha) were established within fragmented low land moist deciduous forests of Tripura. All woody plants ≥10 cm girth at breast height (GBH) were measured. A total of 7,134 individuals with mean density of 648.55 stems ha −1 and 16.36 m 2 ha −1 of basal area were recorded, which represented 134 species, 93 genera, and 43 families of woody plants. Diversitydominance curve showed that maximum number of species were ranked >10 due to low abundance value. Maximum distributions of stems (>50%) were recorded at lowest girth class (10-30 cm) as an indication of advanced regeneration and significantly declined towards upper girth ( 2 adj = 0.93; < 0.0001) and height ( 2 adj = 0.95; < 0.0001) classes, which also indicated that some plants were adopted with ongoing disturbances through both seeded and nonseeded regeneration. Species richness ( 2 adj = 0.49; = 0.05), dominance ( 2 adj = 0.68; = 0.009), and density ( 2 adj = 0.62; = 0.02) were significantly increased at different disturbance intensities. Disturbances strongly influenced typical community association and structure by increasing diversity and population at certain magnitude and thereby showed declining trend towards maturation. Fragmented moist deciduous forests seek immediate attention as they represent spatial habitat for many economical or ecological important species, thus sustaining local biodiversity for livelihoods.

“…The concern with extensive deforestation is the resulting 'forest island' habitats within the fragmented landscape that can be more easily accessed for further degradation, such as over-hunting, ground fi res, and logging (Cayuela et al 2006). Habitat area loss and patch isolation can change predator-prey dynamics, competitive interactions, and species composition, which may affect community structure (Bollen & Donati 2006), reduce species diversity (Hill & Curran 2001), or lead to extinction of vulnerable species (e.g., Burkey 1995;Weaver et al 1996). Smaller forest fragments can also result in the 'empty forest' syndrome (and often from human activity) where trees are still standing but the species that make up the complex ecosystem are not (Redford 1992;Robinson 1996).…”

Does population increase equate to conservation success? Forest fragmentation and conservation of the black howler monkey

et al. 2011

The Community Baboon Sanctuary (CBS) in Belize is a community reserve for the endangered black howler monkey (Alouatta pigra). This study assessed the performance of the CBS as an International Union for Conservation of Nature (IUCN) Category IV protected area through deforestation and forest fragmentation of the CBS and 500 m river buffer, and impacts on black howler monkey habitat over 15 years (1989)(1990)(1991)(1992)(1993)(1994)(1995)(1996)(1997)(1998)(1999)(2000)(2001)(2002)(2003)(2004). Using satellite imagery remote sensing and landscape metrics, this study helps fi ll the gap in our understanding of forest fragmentation processes and habitat provision, using the black howler monkey as a specifi c example. Increased fragmentation resulted in decreased forest cover by 33% within both the CBS and river buffer. However, connectivity between habitat patches has remained high, indicating that dispersal and colonising potential between most forest patches has not been jeopardised. We conclude that conservation within the CBS may be more complex than simply equating forest conservation with black howler monkey conservation. One could say the CBS has been successful at black howler monkey conservation, as documented by population increases over the past 20 years. However, if the conservation objective is forest preservation, one could conclude conservation failure and may signal that the CBS should not be managed for a single outcome as assigned by an IUCN Category IV designation.
