The relative impacts of hunting and habitat on waterbird community were studied in agricultural wetlands of southern India. We surveyed wetlands to document waterbird community, and interviewed hunters to document hunting intensity, targeted species, and the motivations for hunting. Our results show that hunting leads to drastic declines in waterbird diversity and numbers, and skew the community towards smaller species. Hunting intensity, water spread, and vegetation cover were the three most important determinants of waterbird abundance and community structure. Species richness, density of piscivorous species, and medium-sized species (31–65 cm) were most affected by hunting. Out of 53 species recorded, 47 were hunted, with a preference for larger birds. Although illegal, hunting has increased in recent years and is driven by market demand. This challenges the widely held belief that waterbird hunting in India is a low intensity, subsistence activity, and undermines the importance of agricultural wetlands in waterbird conservation.

When leopards are found in human-dominated landscapes, conflicts may arise due to attacks on people or livestock loss or when people retaliate following real and perceived threats. In the plantation landscape of the Valparai plateau, we studied incidents of injury and loss of life of people and livestock over time (15 – 25 y) and carried out questionnaire surveys in 29 plantation colonies and eight tribal villages to study correlates of livestock depredation, people's perception of leopards, and preferred management options for human – leopard interactions. Leopards were implicated in an average of 1.3 (± 0.4 SE) incidents/year (1990 – 2014) involving humans and 3.6 (± 0.8 SE) incidents/year (1999 – 2014) involving livestock, with no statistically significant increasing trend over time. Most incidents of injury or loss of life involved young children or unattended livestock, and occurred between afternoon and night. At the colony level, livestock depredation was positively related to the number of livestock, but decreased with the distance from protected area and number of residents. Half the respondents reported seeing a leopard in a neutral situation, under conditions that resulted in no harm. All tribal and 52% of estate respondents had neutral perceptions of leopards and most (81.9%, n = 161 respondents) indicated changing their own behaviour as a preferred option to manage negative interactions with leopards, rather than capture or removal of leopards. Perception was unrelated to livestock depredation, but tended to be more negative when human attacks had occurred in a colony. A combination of measures including safety precautions for adults and children at night, better livestock herding and cattle-sheds, and building on people's neutral perception and tolerance can mitigate negative interactions and support continued human – leopard coexistence.
- Conference Proceedings2017Migratory livestock grazing significantly impacts rangeland vegetation and wild-ungulate population in the Indian Trans-Himalaya12th International Mammalogical Congress, 2017. Perth, Australia
Intense livestock grazing outcompetes wild-ungulates in low-productivity rangelands. This is a long-standing and highly debated conservation problem globally. We examined impacts of migratory livestock grazing on Trans-Himalayan rangeland and Asiatic ibex, a wild-ungulate and primary prey of the endangered snow leopard. Vegetation and ibex were sampled in an intensely grazed (livestock density 63 sheep-goat/km2) and ungrazed areas, during spring (before-grazing), summer (during-grazing) and autumn (after-grazing). Proportionate to vegetated area, independent randomly laid 1mX1m plots were sampled for vegetation cover and biomass estimation (Cover: NUngrazed=237; NGrazed=127; Biomass: NUngrazed=119; NGrazed=64). Ibex density and young:adult-female ratios were estimated by repeatedly sampling 17 trails using double-observer method across both treatments for the three time periods and two consecutive years. Graminoid and herb biomass were significantly higher in ungrazed than grazed area (ANOVA; Graminoid: FTreatment=16.05; P=<0.001; Herb: FTreatment=22.75; P=< 0.001). Overall vegetation composition was dissimilar across ungrazed and grazed area (Morisita Index 0.18), however, palatable species composition was similar (Morisita Index 0.70). Biomass of palatable species was 2.25 times higher in ungrazed than grazed area. Total off-take of dry forage by migratory livestock from grazed pastures (61 km2) was 10,658 kgs km-2 over two months of grazing. Ibex density was 1.80-7.0 times higher in ungrazed than grazed area in 2015, while 2.45-4.7 times higher in ungrazed than grazed area during 2016. Ibex yearling:adult-female ratio was six times higher in ungrazed than grazed area. Significant reduction in forage availability lowered ibex density and yearling:adult-female ratios in grazed area, suggesting migratory livestock outcompetes ibex through exploitative competition.
