Investigating Factor Associate with the Spatial Distribution of Tiger Abundance Across the Bangladesh Sundarbans

Detection Probability
Abstract:
The Sundarbans of Bangladesh is one of the last remaining source populations of tigers,
but measuring their abundance is particularly difficult in this habitat. Occupancy based
methods may provide a useful alternative to abundance estimation. The basic sampling
protocol used for estimation of detection-nondetection of tiger tracks by visiting
randomly selected khals(canals) for the presence of tracks sets. To predict tiger track
abundance in relation to a suitable habitat index, we used a generalised linear mixed
effects model. Next, three levels of management zones were outlined for tiger
conservation according to the habitat index and tiger track density. Three repeated
surveys were conducted from February - March 2010. These consecutive surveys in the
mangroves concluded that tiger occupied 85% (95% CI 0.77-0.91) of the study area and
the range of detection rate in five dominant habitats was 59% to 87%. Among the five
dominant vegetative habitats in the Sundarbans about 81% areas is occupied by sundri
(Heritiera fomes) and gewa (Excoecaria agallocha). 48% tiger track sets were detected
in the dominant gewa habitat, which assist to define management priorities. The
surveyed technique would reliably detect tiger occupancy trends in 6% decline with a
power of 0.80 conducting survey every two years. We recommend that repeated tiger
track observations of the presence or absence would be a competent and robust method
for long term tiger monitoring with population occupancy trend effectively in the
mangroves. Continuous habitat restoration program and recommended tiger
conservation strategy in three levels might change the present status of this endangered
species. Three levels ascertain indifferent ecological constraint, besides this, most of the
tiger range country suffers fund limitation for tiger conservation. So our
recommendation is to locate the highest endeavour according to the landscapes capacity.
