The Nam Et - Phou Louey National Protected Area (NEPL) is known for its diverse community of carnivores, and a decade ago was identified as an important source site tiger conservation in Southeast Asia. However, there are reasons concern that the status this high priority has deteriorated, making need updated information urgent. This study assesses current diversity mammals birds NEPL, based on camera trap surveys from 2013 to 2017, facilitating assessment protected area management date. We implemented dynamic multispecies occupancy model fit Bayesian framework reveal species diversity. detected 43 different mammal bird species, but failed detect leopard Panthera pardus only two individual tigers tigris, both 2013, suggesting large felids now extirpated presumably also more widely throughout Lao PDR. Mainland clouded Neofelis nebulosa had highest estimates probability initial occupancy, persistence colonization, appeared be most distributed carnivore, followed by dhole Cuon alpinus. Both these emerge further monitoring NEPL landscape. provides recent animal NEPL. Our analytical approach robust flexible include sparse inconsistent data sets multiple assess their via state process, which can often provide insights into population dynamics.

Call Vietnam mouse-deer ‘cheo cheo’ and let empathy save them from extinction: a conservation review and call for name change

Pacific Conservation Biology, Год журнала: 2024, Номер 30(3)

The rediscovery of the silver-backed chevrotain (Tragulus versicolor), an endemic species to Vietnam, in 2019 – after almost 30 years being lost science is a remarkable outcome for conservation. Since its rediscovery, there has been significant concern conservation due hunting wild meat, practice deeply rooted Vietnamese culture. Conservation plans face multiple obstacles as not yet listed endangered by International Union Nature lack data. Given limited effectiveness current measures, we propose that local actions, community cooperation, and empathetic values can help conserve through integrating modern technologies (e.g. Internet, crowdfunding platforms, social media, AI, etc.) with citizen science. Communicating information community, especially children, must stimulate their thinking imagination about nature, develop curiosity desire protect wildlife, eventually build eco-surplus core mindsets. To successfully awaken human within incorporate them into endeavours, messages referring ‘mouse-deer’, ‘chevrotain’, or scientific name T. versicolor are largely ineffective they fail engender feelings familiarity. Therefore, suggest calling mouse-deer ‘cheo cheo’, create familiarity closeness, environmental conscience, imagination. All these factors encourage conservationists, scientists, government support building

Design, monitoring and evaluation of a direct payments approach for an ecotourism strategy to reduce illegal hunting and trade of wildlife in Lao PDR

PLoS ONE, Год журнала: 2018, Номер 13(2), С. e0186133 - e0186133

Ecotourism as a strategy for achieving biodiversity conservation often results in limited impact relative to its investment and revenue return. In cases where an ecotourism has been used, projects are frequently criticized not providing sufficient evidence on how the reduced threats or improved status of it purports protect. Lao PDR, from directly linked dependent improvements there is no that enterprises have contributed conservation. other developing countries, direct payments through explicit contracts return ecosystem services proposed more cost-effective means conservation, although further research needed evaluate this approach. To address need, new model was tested Nam Et-Phou Louey National Protected Area (NPA) PDR using approach create incentives villagers increase wildlife populations. Over four-year period, we monitored along theory change assumptions about linkages between intermediate biological outcomes. Preliminary show negative correlation benefits hunting infractions target villages; sign sector NPA three-fold across NPA's non-tourism sectors; overall sightings. This case provides key lessons design strategy, including combine threat monitoring data sightings effectiveness, setting rates village fees, utility protecting very rare species.

Abstract We used radiocollars and GPS collars to determine the movements habitat selection of golden jackals (Canis aureus) in a seasonally dry deciduous forest with no human settlements eastern Cambodia. also collected analyzed 147 scats from their seasonal diet prey selection. The mean (± SE) annual size home-range ranges (47.1 ± 2.5 km2; n = 4), which were mutually exclusive between mated pairs, was considerably larger than that previously reported for this species, resulting an extremely low density (0.01 jackal/km2). unusually large home probably due harsh season when most understory vegetation is burned nearly all waterholes up, thereby causing decline availability small vertebrate prey. Resident groups consisted alpha pair, but betas, situated only areas not occupied by leopards (Panthera pardus) dholes (Cuon alpinus). Jackals avoided dense forests streams, had strong dirt roads, possibly avoid predators. Overall jackal diverse, at least 16 items identified, there significant difference composition cool-dry hot-dry seasons. Scat analysis showed main food consumed processional termites (Hospitalitermes spp.; 26% biomass consumed), followed wild pig (Sus scrofa; 20%), muntjac (Muntiacus vaginalis; civets (17%). Compared available biomass, random consumption ungulates because selectively over ungulate species. Dietary overlap relatively low, patterns indicated preying on rather scavenging kills carnivores. Our results adaptable opportunistic species exhibits unique behaviors survive extreme environment near edge its distribution.

The environmental impact assessment (EIA) is a nearly universal instrument intended to limit or offset the tolls of development projects. Here, I describe some key shortcomings EIAs in terms their real-world application, especially developing nations that harbor much world's imperiled biodiversity. A surprisingly large number suffer from major inaccuracies and are green-lighting projects will have serious societal costs. summarize by proposing eight strategies help improve conservation capacities EIAs.

Diet, prey selection, and activity of Asian golden cats and leopard cats in northern Laos

Journal of Mammalogy, Год журнала: 2020, Номер 101(5), С. 1267 - 1278

Опубликована: Авг. 14, 2020

Abstract The Asian golden cat (Catopuma temminckii) occurs in small, declining, and highly fragmented populations throughout Southeast Asia, whereas the smaller leopard (Prionailurus bengalensis) is common widespread. In contrast to cats, little known about ecology of resource partitioning between these species has not been studied. We used DNA-confirmed scats, camera-trap data, prey surveys, determine diet, selection, activity, cats a protected area northern Laos. two felids had different diets: consumed mostly ungulates (35% biomass consumed), murid rodents (23%), carnivores (15%), (79%). were random their consumption ungulates, because muntjac (Muntiacus spp.) selectively over larger indicating preyed upon rather than scavenged. Dietary overlap felid was moderate (R0 = 0.60), dietary niche breadth (B 8.44) nearly twice as high that (4.54). mean (± SD) scat diameter greater for (2.1 ± 0.3 cm) (1.8 0.2 cm), although diameters scats considerably previously assumed this species. differed activity patterns, diurnal, nocturnal, they did differ use elevation, suggesting there no habitat segregation. Overall, appeared coexist with potential predator competitor, by exhibiting temporal partitioning. Our results showed important management might be conserving cats.

Long‐term monitoring of wildlife populations for protected area management in Southeast Asia

Conservation Science and Practice, Год журнала: 2021, Номер 4(2)

Опубликована: Дек. 21, 2021

Abstract Long‐term monitoring of biodiversity in protected areas (PAs) is critical to assess threats, link conservation action species outcomes, and facilitate improved management. Yet, rigorous longitudinal within PAs rare. In Southeast Asia (SEA), there a paucity long‐term wildlife PAs, many threatened lack population estimates from anywhere their range, making global assessments difficult. Here, we present new abundance trends for 11 between 2010 2020, spatial distributions 7 species, based on line transect distance sampling surveys Keo Seima Wildlife Sanctuary Cambodia. These represent the first robust four range are among trend analyses entire SEA region. Our study revealed that arboreal primates green peafowl ( Pavo muticus ) generally had either stable or increasing trends, whereas ungulates semiarboreal declining trends. results suggest ground‐based such as snares domestic dogs, having serious negative effects terrestrial species. findings have important implications across face similar threats yet reliable data.
