Basically through population pressures leading to habitat encroachment and commercial slaughter, India is becoming poorer, day be day, in her still-rich heritage of wildlife. Virgin forests on the plains and in the hilly regions are dwindling. Unfortunately, education and research centres have not cared to educate the youth of the country about the importance of nature conservation.The Author's field endeavours, extending over more than a decade, have helped to reveal that 18 of India's 27 threatened mammalian species—lion-tailed Macaque, Macaque, Nilgiri Langur, Golden Langur, Snub-nosed Langur, Wolf, Asiatic Wild Dog, Malabar Large-spotted Civet, Clouded Leopard, Indian Tiger, Leopard, Snow Leopard, Asian Elephant, Sumatran Rhinoceros, Kashmir Stag, Gaur, Wild Yak, Nilgiri Tahr, and Markhor—have their homes in hilly or montane habitats. Pradoxically, India has the dubious distinction of ranking second in the world, and first among the 15 countries of the Oriental region, in having 27 mammalian species whose world populations are to some extent threatened according to the Red Data Book (IUCN, 1972).

Abstract:When animals or groups of animals in their wild habitats come close to each other within a defined distance, it is termed as an association. Observing two groups of the lion-tailed macaque at Nelliyampathy and Andiparai forests of the Western Ghats of India, we asked whether the lion-tailed macaque associations with the sympatric Nilgiri langur and bonnet macaque were by chance or had any biological significance. Employing ‘all occurrences’ sampling, we recorded an association if a group of another primate species came within 30 m of the focal group of the lion-tailed macaque. Date, time, associating species, activity of the study species and of the associating species, type of interaction, aggressor and the recipient, species displaced and duration of the association were recorded. We used the Waser gas model to calculate the expected frequency and duration of associations and compared them with the observed associations. The lion-tailed macaque spent less time in associations than expected. The lion-tailed macaque and the Nilgiri langur initiated associations less often, and remained in association for less time, than expected by chance. Whereas the expected and observed initiation of associations between the lion-tailed macaque and the Nilgiri langur in Nelliyampathy was significantly different (expected rate = 153; observed rate = 64), in Andiparai, it was not (expected rate = 55.5; observed rate = 61). The expected and observed association duration was significantly different in Nelliyampathy (expected duration = 54 min; observed duration = 15 min) and Andiparai (expected duration = 48 min; observed duration = 19 min). In contrast, we detected few differences between observed and expected association frequency for the lion-tailed macaque and the bonnet macaque. Aggressive interactions were common in areas where density of the Nilgiri langur groups was high. This is the first study on Asian primates using the ideal gas approach to show that primates do not form active associations with each other.

Nilgiri Langur

Phylogenetic conservatism or rapid anthropogenic habitat modifications could increase the incidences of interspecific associations of Hanuman and Nilgiri langurs (Family: Cercopithecidae, subfamily: Colobinae) in the southern Western Ghats.  Opportunistic surveys were conducted at the Silent Valley National Park, Kerala and around Devimalai Ghats, Tamil Nadu for  Tufted Grey-Nilgiri Langur association. Based on the observations from Researchers, field assistants, forest staff, and local people, the data in terms of the time of the sighting, number of individuals, phenotypes of individuals, and the time the interaction lasted, were recorded.  The study reports data on a troop of Nilgiri Langurs (N=13) around O Valley tea estate at Devimalai Ghat, Gudalur, Tamil Nadu with some hybrid looking individuals and a Tufted female Grey Langur amongst them. A total of six  and two uni-male troops of Nilgiri Langurs  and grey langurs respectively with Tufted female Grey Langurs, and aberrant coat colored infants observed at the Neelikkal section of Silent Valley National Park are also reported. The study reasonably speculates that there could be more such locations in the southern western ghats and emphasizes the need for more systematic surveys to understand  and explore the ecology, behavior, molecular, and other likely factors contributing to the conservation of vulnerable Nilgiri langur (Semnopithecus johnii) populations.

The Western Ghats is a chain of mountains and is one of the 33 recognized ecologically sensitive zones in the world. There are several centres of plant endemism and species richness within the Western Ghats. Cullenia exarillata Robyns is a large evergreen tree in the mid-elevation evergreen forests which is endemic to Western Ghats. This tree acts as a hot bed of activity when in flower and functions as a keystone resource for several species of arboreal mammals, including the endangered primate Lion tailed macaque and Nilgiri langur. A preliminary attempt is carried out to regenerate and restore the populations of C.exarillata. Seed germination studies were performed and seeds were treated using 3 different pre-sowing treatments. Seeds were soaked in Dithane-45 for 5minutes, in cow dung extract for two nights and in gibberillic acid (100 ppm) for 24 hours. Untreated seeds were also used as control. Dithane-45 treatment showed 80% seed germination and the cow dung extract treatment showed 20% seed germination. Dithane-45 treatment promotes speedy seed germination when compared to other treatments. Therefore, pre-sowing treatment with Dithane-45 for 5 minutes was more effective for this plant.
