We re-assessed tigers Panthera tigris for the IUCN Red List of Threatened SpeciesTM, classifying them as Endangered based on an estimated decline of >50% over 3 generations (21–30 years), with an estimated 4,485 (3,726–5,578) tigers in the wild. However, data suggest that the population is likely stabilizing or even increasing in some places - a co...

Tiger Panthera tigris has most recently been assessed for The IUCN Red List of Threatened Species in 2021. Panthera tigris is listed as Endangered under criteria A2abcd.

Better knowledge for better management: Javan leopard is downlisted to Endangered The latest assessment of the Javan leopard Panthera pardus melas for the IUCN Red List of Threatened Species TM resulted on revised categorization of the species from Critically Endangered (CR) to Endangered (EN). This downlisting was defined based on better informati...

The latest assessment of the Javan leopard Panthera pardus melas for the IUCN Red List of Threatened SpeciesTM resulted on revised categorization of the species from Critically Endangered (CR) to Endangered (EN). This downlisting was defined based on better information and data quality about the geographical distribution, population size, and threa...

The history of three sub specieses of Indonesian tigers, what we should learn from losing 2 sub-species of tigers (bali tiger and javan tiger) and the strong effort of Indonesia's conservation warriors to save sumatran tigers.

Destruction of tropical rainforests reduces many unprotected habitats to small fragments of remnant forests within agricultural matrices. To date, these remnant forest fragments have been largely disregarded as wildlife habitat, and little is known about mammalian use of these areas in Sumatra. Here, we conducted camera trap surveys (2285 trap-nigh...

With the extirpation of tigers from the Indonesian island of Java in the 1980s, the endemic and Critically Endangered Javan leopard is the island's last remaining large carnivore. Yet despite this, it has received little conservation attention and its population status and distribution remains poorly known. Using Maxent modeling, we predicted the l...

List of predicted suitable landscapes and land use characteristics in each landscape. Suitable landscapes were defined based on Maxent model outputs with logistic probabilities of 0.42 or greater. (PDF)

This chapter sets the overall context by providing a brief overview of the historical and current status of wild tiger populations and social, cultural, and scientific perspectives on the tiger.

Current levels of illegal wildlife trade for many in-demand species are unsustainable and place them at a heightened risk of extinction. While several Asian protected areas standout for their remarkable successes in tackling poaching, the threat continues nonetheless. We analyse a decade of law enforcement data from a Sumatran protected area to inv...

There have been few targeted studies of small felids in Sumatra and there is little information on their ecology. As a result there are no specific management plans for the species on Sumatra. We examined data from a long-term camera trapping effort, and used Maximum Entropy Modeling to assess the habitat use and distribution of Sunda clouded leopa...

Small and medium cat diversity and spatio-temporal distribution in Gunung Leuser National Park, Sumatra, Indonesia, was recorded between March and October 2010. A pair of infra-red cameras was set up in each of the 68 locations resulting in 54 in- dependent events of small and medium cats in 3,452 trap nights. Four of the five small and medium cat...

The loss and fragmentation of substantial areas of forest habitat, in combination with rampant hunting, has pushed many of Southeast Asia’s megafauna species to the verge of extinction. However, the extent of these declines is rarely quantified, thereby weakening lessons learned and species-based management. This need not be the case as a prolifera...

We conducted the first systematic survey on Sumatran rhinoceros following a robust patch occupancy framework in 3,500 km(2) of Bukit Barisan Selatan National Park (BBSNP), Sumatra, Indonesia. We surveyed 55 grids (72.25 km(2)) between November 2007 and July 2008 to generate a reliable estimate of the proportion of area occupied (occupancy) by the S...

The majority of wild Sumatran tigers persist in 12 Tiger Conservation Landscapes (TCLs) covering approximately 88,000 km². Despite these large areas of forest, an increase in the rate of habitat fragmentation and loss in recent years threatens the integrity of these landscapes. In addition, continued demand for tiger body parts, non-selective ungul...

The endemic Sumatran striped rabbit Nesolagus netscheri, categorized as Vulnerable on the IUCN Red List, is one of the rarest lagomorphs and little is known about its ecology, status or distribution. After nearly a decade with no published sightings, new camera-trap photos have been taken and observations made in Bukit Barisan Seletan and Kerinci S...

Large carnivores living in tropical rainforests are under immense pressure from the rapid conversion of their habitat. In response, millions of dollars are spent on conserving these species. However, the cost-effectiveness of such investments is poorly understood and this is largely because the requisite population estimates are difficult to achiev...

The number of biological species that occurs at a particular geographic unit, whether that be global, a biogeographic region, country, or national park, is of great relevance to the management and conservation of biodiversity. Major policy initiatives at the international, national, and regional levels have committed entire government programs to a...

The majority of wild Sumatran tigers are believed to live in 12 Tiger Conservation Landscapes covering approximately 88,000 km(2) . However, the actual distribution of tigers across Sumatra has never been accurately mapped. Over the past 20 years, conservation efforts focused on the Sumatran tigers have increased, but the population continues to de...

In recent decades there have been an increasing number of camera trap studies occurring throughout Southeast Asia. Although not the target species, photographs of marbled cats are occasionally recorded and may give insight to some aspects of the species’ ecology. Here we report on a series of camera trap photographs that were recorded of a melanist...

The 1,080 km2 Batang Gadis National Park in the North Sumatra province of Indonesia was established in December 2004 by the regional government of Mandailing Natal district. The Park has the potential to make an important contribution to tiger conservation but lacks scientific data on the occurrence of the species. This study aimed to assess the ti...

We examine the abundance and distribution of Sumatran tigers (Panthera tigris sumatrae) and nine prey species in Bukit Barisan Selatan National Park on Sumatra, Indonesia. Our study is the first to demonstrate that the relative abundance of tigers and their prey, as measured by camera traps, is directly related to independently derived estimates of...

The remarkable large-mammal fauna of the Indonesian island of Sumatra is one of the most endangered on Earth and is threatened by rampant deforestation. We used remote sensing and biological surveys to study the effects of deforestation on populations of endangered large mammals in a Sumatran landscape. We measured forest loss and created a predict...
