Recommendations for the Future Conservation of the Nilgiri Tahr by
Daniels et el based on their study
(2006) The
survey carried out during May-August 2006 has highlighted a few important
aspects about the status of the Nilgiri Tahr over its range. The species
continues to survive in fragmented population units in highly variable numbers
in many localities within the 6 landscapes in the states of Tamilnadu and
Kerala. The presence of the Tahr in Minnamparai, Kuchimudi, Kadavari-Kambakkal,
Maramalai and Golf Course has been reported for the first time based on the
present surveys. Interestingly, the direct evidence for the occurrence of the
Tahr that the present study was able to gather has indicated that the species is
more widely distributed at mid-elevations; around 1300m ASL. This may be a
rather seasonal pattern as the survey coincided with the southwest monsoon
season. The
present survey backed with comprehensive review of published information
suggests that the many earlier estimates of the local population sizes of the
Tahr are quite flawed and inconsistent. Whereas the available estimates for the
state of Kerala are apparently reasonable, those for Tamilnadu are rather
unreliable with the exception of the Nilgiri Hills and Anaimalai Hills
landscapes. The general pattern of variation and inconsistencies detected in the
estimates published or quoted during the past four decades clearly suggest that
the population size of 2000-2500 Tahr that has been widely accepted is an
over-estimate (Daniels et al, 2006). Such a realization emphasizes the
need to device more systematic and stringent procedures for the estimation of
Tahr population sizes both at site/local level and at the scale of the
landscape. As
there is very little known about the territory size of solitary males and the
home ranges of specific herds, it is important that such ecological aspects of
the Nilgiri Tahr are better studied in the immediate future. Pellet piles and
rutting pits (Daniels, 2006) are probably ideal landmarks that can be used to
map the distribution of territories (within specific habitats) and the home
ranges in and across each Tahr landscape. In fact considering the rugged
topography and the inaccessibility of most Tahr landscapes, it has even been
suggested that aerial surveys should be the best way to estimate the population
size of the species at least in a few landscapes (P O Nameer, personal
communication). Despite
the rather significant recovery of a species that had reached the brink of
extinction during the late 19th century (Schaller, 1988) a population
size that is smaller than 2000 animals does not suggest that it is a resilient
animal. The Nilgiri Tahr is still a critically endangered mountain goat and in
dire need of better integrated conservation action over its entire range. As has
been pointed out by Mishra and Johnsingh (1998) the single largest conservation
unit is the Anaimalai-Parambikulam and Eravikulam Protected Areas. Around 60% of
the entire population of the Nilgiri Tahr may be found here. The other
strongholds of the species are the Mukurti NP, the Tirunelveli Hills-Agasthiya
Malai and the Palani Hills-High Wavy Mountains landscapes. The
largest population units of the Nilgiri Tahr however, are within landscapes that
are contiguous and spread across the two States. Although not confirmed, there
are clear indications that herds move across State boundaries. Such a
probability calls for greater inter-state cooperation in the conservation of the
species. From the present study and other published information it is apparent
that the number of locations where the Tahr is presently found (or reported) is
higher within Tamilnadu. However, as evident, pressures of poaching and other
human impacts on the habitat are also higher here than in Kerala. In
Tamilnadu, for instance, conservation efforts specifically focused on the Tahr
are limited to the Grass Hills and Mukurti NP. Other landscapes that have the
potential of supporting good numbers of the Tahr are the Palani Hills-High Wavy
Mountains landscape that includes the Meghamalai & Varshanaadu Forest Ranges
and the Tirunelveli Hills-Agasthya Malai landscape. As the latter is now a part
of the Neyyar WLS, Kalakkad-Mundanthurai Tiger Reserve and Kanyakumari Wildlife
Sanctuary, it is recommended that the Palani Hills-High Wavy Mountains landscape
be designated as a Nilgiri Tahr sanctuary. In
addition, the smaller population units of the Nilgiri Tahr that are scattered
throughout the range in Kerala and Tamilnadu outside the existing system of
Protected Areas should be more carefully assessed for their size, structure and
vulnerability. The quality and extent of the fragmented habitats that the
smaller population units depend on should also be assessed. By establishing
suitable corridors (within and across the Tahr landscapes) and adopting the
principles of meta-population management, the future of the Nilgiri Tahr can be
made secure. Definite
and well-planned steps should be adopted by both States to improve the quality
and extent of the available Tahr habitats. In this regard, the suggestions made
by Mishra and Johnsingh (1998) for the phased removal of pine and eucalypts from
the Grass Hills, should be considered for immediate action. It has to be stated
that during the present study we observed the Tamilnadu Forest Department
already in the process of phasing out wattle in and around the Mukurti NP. The
recent steps taken by the Eravikulam NP authorities to regulate vehicle movement
in Rajamalai and keep close watch on the visitors have helped reduce disturbance
and in keeping the Park clean. These are certainly commendable and positive
action on the part of the states. Considering
the fragmentation of habitat leading to isolated populations, a landscape
approach is required for the future programmes. The report has further
recommended assessment of quality of habitats for their long term suitability
and sustainability. Scientific means of improving the available forage (as
against the total grass/shrub biomass) has to be seriously explored and adopted.
Tamilnadu Forest Department is removing the exotic monocultures along the
periphery of the Mukurti National Park. This is a commendable initiative and is
worthy of replication in other Tahr ares overrun by exotics. Inter-state
cooperation in standardizing and synchronizing the annual Tahr population
estimation is must to arrive at staristcally valid population estimates.
Community participation for conservation has to be encouraged. Without support
of the local communities conservation initiatives will not take off in a thickly
populated country like India. The addition of adjoining areas of Munnar Forest
Division and Marayur Forest Division to Eravikulam National Park is very crucial
for maintaining the existing population of the Park.(Rice,C.G,1984). This
proposal was subsequently endorsed by the Kerala State Wildlife Advisory Board,
but is still hanging fire. Proposals
