Introduction
To plan for conservation of tigers, knowledge of their conservation status and the threats to their existence is required. Since 1997 potential tiger habitat across the species’ global range has been identified, and remnant vegetation divided into grades of tiger habitat representing high, medium or low probability of tiger population persistence, or so-called Tiger Conservation Units (Dinerstein et al., Reference Dinerstein, Wikramanayake, Robinson, Karanth, Rabinowitz, Olson, Mathew, Hedao, Connor, Hemley and Bolze1997). Sixteen such Units overlap Peninsular Malaysia, where tigers have been considered threatened with extinction for decades (Blanchard, Reference Blanchard1977). However, knowledge of the status of tigers in the wild in these Units is poor (Topani, Reference Soisalo and Cavalcanti1990; Elagupillay & Wan Shahruddin, Reference Elagupillay and Wan Shahruddin1999). Surveys and tiger-livestock conflicts during the 1980s and 1990s indicated the existence of some tigers (Elagupillay, Reference Elagupillay1983, Reference Elagupillay1984; Ratnam et al., Reference Ramakrishnan, Coss and Pelkey1995) but most information was through unconfirmed reports (Rabinowitz, Reference O'Brien, Kinnaird and Wibisono1999).
Recognizing the paucity of information on tigers, and wanting to mitigate effects on tiger survival of future intrusions into these habitats, the Malaysian Department of Wildlife and National Parks (DWNP) embarked on a programme to: (1) determine distribution and status of tigers in Peninsular Malaysia and calibrate the model of putative priority areas (Dinerstein et al., Reference Dinerstein, Wikramanayake, Robinson, Karanth, Rabinowitz, Olson, Mathew, Hedao, Connor, Hemley and Bolze1997); (2) collect information on tiger numbers, movements, behaviour, home range size and habitat use in a key tiger site identified from the survey programme; and (3) train Malaysian wildlife biologists in surveying and studying tigers to facilitate the future management and conservation of tiger populations in the region.
This study, conducted by DWNP and the Wildlife Conservation Society (WCS), addressed goals (1) and (3). Specifically, several types of information on tigers are important for their effective management in Malaysia: (a) distribution across potential habitats, (b) comparative abundance within and between habitats, and (c) threats specific to tigers and their prey, especially poaching. This study addressed (a) by determining patterns of detection or non-detection of tigers using camera traps, (b) by sampling tiger abundance using camera traps, and (c) by records of human intrusion from camera traps, field observations, and general appraisals of habitat condition and human disturbance from other studies (Laidlaw, Reference Laidlaw2000). A study by DWNP and the University of Florida at Gainesville to address goal (2) is reported elsewhere (Kawanishi & Sunquist, Reference Kawanishi and Sunquist2004).
Study sites
Tiger surveys at nine forest sites spanned the states of Perak, Terengannu, Kelantan and Pahang (Fig. 1). The sites (1) have the potential to support tiger populations in the long-term (Dinerstein et al., Reference Dinerstein, Wikramanayake, Robinson, Karanth, Rabinowitz, Olson, Mathew, Hedao, Connor, Hemley and Bolze1997); (2) represent varying forest types and management histories (logged and unlogged forest, protected forest and forest reserves, forest fragments and continuous forest, edge and core forest, tiger conflict and non-conflict zones; Table 1); (3) have information available suggesting tiger presence (DWNP, unpubl. data). Four sites are inside the high priority Tiger Conservation Unit #129, one in the medium-priority Unit #130, one adjacent to the low priority Unit #134, and one inside Taman Negara National Park. Two other sites are in forest reserves legally protected from clearance but where selective timber extraction may be licensed. Full descriptions of the sites are in DWNP/WCS (2004).
Location of nine sites surveyed for tigers (Table 1) in Peninsular Malaysia during December 1997-December 1999. The numbered locations give the approximate position of each study site; locations of individual camera traps are not shown. A tenth site also shown here, Krau Wildlife Reserve, was surveyed subsequently during 2000 (Laidlaw, Reference Laidlaw2002).

Methods
Camera traps (CamTrak South Inc., Georgia, USA) consisting of a weatherproof Infinity Mini DLX Olympus camera with a 35 mm lens and flash, and a passive infrared sensor, housed in a waterproof casing, were triggered and a photograph taken when the sensor detected a difference in heat and motion across a beam in front of the device. Cameras were programmed to record the date and time on 400 ISO film, with a 3-minute time delay to forestall lingering animals from rapidly filling the film. Camera traps were mounted 40 cm above the ground, 3-5 m (the focal length of the camera) from the middle of a trail, and usually left for 4–6 weeks, set for continuous operation day and night (one trap-night = one 24 h period). Information on camera trap set-up and retrieval allowed determination of the number of trap nights over which a camera trap was functional. Surveys were conducted between December 1997 and December 1999 inclusive (Table 2).
Camera traps were placed to maximize tiger detection probability (p; Karanth & Nichols, Reference Karanth and Nichols1998, Reference Karanth and Nichols2002): trail junctions, ridgeline trails, water crossings, passes, and where tracks of tigers and/or tiger prey species were detected during reconnaissance. At each study site camera traps were established on a 10*4 km grid. Single camera traps were placed at optimal locations inside 15–20*1 km2 cells so that no holes in the web of trap locations exceeded a tiger's home range in size (Karanth & Nichols, Reference Karanth and Nichols2002). At ≤5 additional locations, usually where tiger signs were detected, paired traps were positioned on opposite sides of the trail/road to allow simultaneous photography of both sides of a tiger, thereby permitting identification of individual animals from stripe patterns. Such paired camera traps were dispersed for maximum spatial coverage. On average 19 ± 1 camera trap set-ups (range: 13-27; Table 2) were used at each site. For additional details of methods see Laidlaw (Reference Laidlaw1999).
Independent events (detections) comprised (1) consecutive photographs of different individual conspecifics or (2) consecutive photographs of conspecifics more than 10 minutes apart. Photographs without inscribed times (reflecting flash overexposure or errors in setting the camera trap) were not included in analyses. Location-specific relative abundance indices (RAI) were calculated for tigers following O'Brien et al. (Reference Nyhus and Tilson2003) as the number of detections divided by the number of functional trap nights. This index, which was scaled to detections per 100 trap-nights, should increase with population density.
Time constraints and access difficulties rendered mark-recapture methods (as recommended for estimating tiger abundance; Karanth & Nichols, Reference Karanth and Nichols2002) impractical, and these results cannot be compared with abundance estimates from mark-recapture studies. However, to compare abundance within this study, naïve density of tigers, ![$\[\hat D\]$](https://static.cambridge.org/binary/version/id/urn:cambridge.org:id:binary:20180418092722550-0738:S0030605307001019:S0030605307001019_equ01.gif?pub-status=live){kind=small}
, was calculated using the number of tiger individuals captured in camera traps, ![$\[\hat N\]$](https://static.cambridge.org/binary/version/id/urn:cambridge.org:id:binary:20180418092722550-0738:S0030605307001019:S0030605307001019_equ02.gif?pub-status=live){kind=small}
, and by assuming a sampling effective area, ![$\[\hat A\]$](https://static.cambridge.org/binary/version/id/urn:cambridge.org:id:binary:20180418092722550-0738:S0030605307001019:S0030605307001019_equ03.gif?pub-status=live){kind=small}
, at each site. This abundance estimate was translated into density by:
where 
is the sampling area with buffer width W. 
was calculated by linking the outermost locations of camera traps and adding a buffer with radius W equivalent to half the absolute maximum distance moved (AMDM) between recaptures of individual tigers. AMDM is superior to mean maximum distance moved (MMDM) when sample sizes are small because MMDM tends to underestimate W (Kawanishi, Reference Kawanishi2002) thus inflating estimated densities (Soisalo & Cavalcanti, Reference Sodhi, Koh, Brook and Ng2006).
Spatial extent of human use at each site, and hence potential threats to tigers, was measured as the proportion of sampling locations where camera traps photographed people.
Results
A total of 174 camera traps deployed across 151 sampling locations at the nine study sites recorded 2,371 photographs from 6,259 trap-nights (Table 2). Apart from tigers, 34 other species of native mammal were positively identified from photographs (Appendix), nearly a third (11 species) of which are threatened or Data Deficient (IUCN, 2007). Mammal species richness cannot be compared between sites because sampling efforts varied and species totals did not reach an asymptote at any of the sites. However, species accumulation rates were relatively high at Ulu Temiang, Gunong Tebu and Lepar, medium at Ayer Ngah, Temenggor and Taman Negara, and low at Bintang Hijau, Jengai and Cameron Highlands. Camera traps recorded at least 11 species of reptiles and birds. Three birds are threatened and three Near Threatened (IUCN, 2007).
Ten individual tigers could be identified from 35 of 51 tiger photographs from 36 sampling locations across the nine sites. Within tiger-occupied sites, tigers were recorded at a mean of 18 ± SE 6% of sampling locations per site. Overall, one tiger was photographed every 122 trap nights. Tigers were not recorded at Taman Negara, Cameron Highlands and Jengai but were detected at almost half the locations at Ulu Temiang. Average tiger detection rate was highest at Ulu Temiang and lowest at Ayer Ngah (Table 3). Between 1 and 3 individual tigers were detected at six sites. Naïve density estimates ranged from 0.51–0.53 tigers per 100 km2 at Lepar, Gunong Tebu and Ayer Ngah to 1.95 tigers per 100 km2 at Temenggor (Table 3).

4 Calculated sampling area was larger than size of the reserve so the latter was used to estimate density

Camera traps recorded people at a mean 18 ± SE 4% (range 0–33%) of sampling locations across the nine sites. No people were recorded at Bintang Hijau whereas a third of traps photographed people at Ulu Temiang and Ayer Ngah. Human traffic represented a mean 4 ± SE 1% of all traffic (range 0-8%), and appeared highly localized, especially at Ayer Ngah, Cameron Highlands and Jengai, with a few sampling locations detecting heavy traffic but most not detecting any.
Discussion
The data presented here were collected 8 years ago (1997-1999), a short period in ecological terms and equivalent to c. 2 tiger generations (Smith & McDougal, Reference Shepherd and Magnus1991). However, because of the rapid rate at which tropical forests in Asia are changing relative to other continents (Sodhi et al., Reference Smith and McDougal2004) and the speed with which tigers can be poached, we invoke findings from related studies and more recent data in drawing conclusions about the conservation status of tigers in Peninsular Malaysia.
In nine sampled forest areas tigers were found in multiple parts of a Level I Tiger Conservation Unit (#129: Temenggor, Ayer Ngah, Gunong Tebu, Ulu Temiang), in a Level II Unit (#130: Bintang Hijau) and adjacent to one Level III Unit (#134: Lepar; Dinerstein et al., Reference Dinerstein, Wikramanayake, Robinson, Karanth, Rabinowitz, Olson, Mathew, Hedao, Connor, Hemley and Bolze1997). A separate survey of a 450 km2 plot inside Krau Wildlife Reserve (Fig. 1), also part of Unit #129, found at least two adult tigers (Laidlaw, Reference Laidlaw2002). Tigers were not detected at three sites: a site in the Cameron Highlands, Ulu Sat in eastern Taman Negara, and Jengai, which lies south-east of Taman Negara. Tigers do inhabit central and western Taman Negara, at Merapoh, Kuala Terengan and Kuala Koh (Kawanishi & Sunquist, Reference Kawanishi and Sunquist2004), implying that tiger distribution even within a single contiguous tract of protected primary forest is patchy, and not readily predictable from habitat.
Tiger-human conflict investigations during 2001–2005 confirmed persistence at each site where tigers were recorded in this study (DWNP, unpubl. data; S. Elagupillay, pers. obs.), suggesting potentially stable tiger occurrence at these sites. All except one exceeds 100 km2 (Table 1), a threshold below which tigers, and some other large mammals, may rapidly go extinct (Woodroffe & Ginsberg, Reference Wikramanayake, McKnight, Dinerstein, Joshi, Gurung and Smith1998; Laidlaw, Reference Laidlaw2000). Although tigers currently inhabit Ulu Temiang and Ayer Ngah these small areas have tenuous connections with larger habitat blocks and may not therefore support tigers in the long-term.
Tiger relative abundance varied 10-fold and the number of individual tigers detected varied three-fold. The naïve estimates of density here (0.51-1.95 tigers per 100 km2) are of the same order as those from capture-recapture studies in Malaysia (1.45–1.87; Kawanishi & Sunquist, Reference Kawanishi and Sunquist2004) and elsewhere in South-east Asia (O'Brien et al., Reference Nyhus and Tilson2003; Johnson et al., Reference Johnson, Vongkhamheng, Hedemark and Saithongdam2006). Tigers no doubt occur outside the nine sites studied and in other states that we were unable to cover. If the observed naïve densities (0.67 ± 0.25 tigers per 100 km2) typify true density across Malaysian tiger priority areas (29,159 km2; Dinerstein et al., Reference Dinerstein, Wikramanayake, Robinson, Karanth, Rabinowitz, Olson, Mathew, Hedao, Connor, Hemley and Bolze1997) this would suggest several hundred tigers. However, mark-recapture studies using camera traps from other parts of the country are needed to estimate the population reliably. The present tiger population in Malaysia could be conserved by protecting the available habitat and non-depleted prey populations (Kawanishi et al., 2003) and through appropriate management practices inside and outside protected areas. The recent adoption of the National Physical Plan by the Malaysian Government as the spatial planning tool that proposes to establish a central forest spine to protect environmentally sensitive habitats (FDTCP, 2005), if successfully implemented, augers well for the long-term conservation of tiger populations and their habitats in Malaysia.
Tigers need large (>3,000 km2) contiguous areas for long-term viability (Karanth & Nichols, Reference Karanth and Nichols2002). In Peninsular Malaysia tiger habitat is fragmented and lost through road and power networks, plantations, urban expansion, dams, irrigation, and other developments. Although two-thirds of hill and montane forests remain, 80% of lowland forests have been lost and/or fragmented (Wikramanayake et al., 2002). Most small (<100 km2) fragments now lack tigers and other predators (Laidlaw, Reference Laidlaw2000), in turn affecting ungulate prey densities (Ickes, Reference Ickes2001). Tigers require access to rivers, so disturbance of or along rivers (e.g. by roads, dams or housing) can extirpate them from otherwise suitable areas. Habitat fragmentation increases the accessibility of remaining forest, in turn stimulating further degradation through various activities, notably hunting (Robinson et al., Reference Robinson and Bennett1999) both of tigers and their ungulate prey, thereby driving declines in tiger populations (Ramakrishnan et al., Reference Rabinowitz, Seidensticker, Christie and Jackson1999; Madhusudan & Karanth, Reference Lynam and Venevongphet & Saypanya2002). Non-vehicular paths, e.g. those of aloewood (Aquilaria spp.) collectors, also facilitate hunting (Abdul Kadir, Reference Abdul Kadir1998; Wan Shahruddin, Reference Topani1998). Aloewood collectors include some Thai and Lao nationals (A.J. Lynam & R.K. Laidlaw, pers. obs.), and they often leave few signs, which may suggest that their impacts are low (Kawanishi & Sunquist, Reference Kawanishi and Sunquist2004). Evidence of hunting by these forest users has been found at several of the sites of this study (Wan Shahruddin, Reference Topani1998).
In general, tropical forest productivity for large mammals is low, and hence hunting levels must be extremely low to be sustainable (Robinson & Bennett, Reference Robinson, Robinson and Bennett2000); in closed forests, sustainable off-take levels are especially low (Robinson, Reference Ratnam, Lim and Nor2000). Examples of sustainable hunting in such forests are rare, even for more rapidly breeding prey such as ungulates and rodents (Robinson & Bennett, Reference Robinson, Robinson and Bennett2000), let alone for the scarcer carnivores. Sustainability of hunting has not been studied in Peninsular Malaysia but unsustainable hunting is rapidly depleting wildlife populations across parts of tropical Asia (Bennett & Robinson, Reference Bennett and Robinson2000; WCS & TRAFFIC, Reference Wan Shahruddin2004).
Besides hunting of their prey, tigers themselves are hunted. Commercial trade in wild tigers and tiger parts has occurred in Asia and across the world for centuries (Nowell, Reference Naiman2000) and occurs today in Malaysia (Elagupillay et al., Reference Elagupillay, Laidlaw and Wan Shahruddin2001), as in other Asian countries (Shepherd & Magnus, Reference Sanderson, Forrest, Loucks, Ginsberg, Dinerstein, Seidensticker, Leimgruber, Songer, Heydlauff, O'Brien, Bryja, Klenzendorf and Wikramanayake2004; Davies, Reference Davies2005). Rates of the loss of tigers to commercial hunting in Malaysia have never been quantified. Tigers are also killed in retribution for livestock depredation and human injury and both are increasing in frequency in Peninsular Malaysia: between 1988 and 1997, 108 tiger-human incidents and 503 tiger-livestock incidents were reported in four and six states respectively (Elagupillay et al., Reference Elagupillay, Laidlaw and Wan Shahruddin2001). The increase in conflicts presumably reflects tigers coming into contact with people as habitats are encroached and their prey base depleted (Woodroffe & Ginsberg, Reference Wikramanayake, McKnight, Dinerstein, Joshi, Gurung and Smith1998; Nyhus & Tilson, Reference Nowell2004). In Malaysia several problem tigers have been taken into captivity, thus depleting the wild population. Tigers are occasionally killed by farmers or when they cannot otherwise be moved but such cases are reported inconsistently.
Harassment from humans may disrupt tiger behaviour and prey populations (Griffiths & van Schaik, Reference Griffiths and van Schaik1993). Human intrusions were evident at eight of our nine survey areas, across up to a third of sampling locations. Tiger activity may be disrupted by human traffic, especially in high human-use areas (Laidlaw & Shaharuddin, Reference Laidlaw and Shaharuddin1998), and this may underlie their low density or absence where human traffic was most intense (Ayer Ngah, Cameron Highlands and Jengai).
In Malaysia few tigers remain, areas of sufficient size to support tigers are limited, and threats are diverse but as yet unquantified. Management efforts should thus focus on protecting and restoring tiger populations in a few priority landscapes. The Main Range (Fig. 1) is the first priority landscape given its large size (c. 20,000 km2) and connectivity with important tiger habitats in southern Thailand (Dinerstein et al., Reference Dinerstein, Wikramanayake, Robinson, Karanth, Rabinowitz, Olson, Mathew, Hedao, Connor, Hemley and Bolze1997). The next priority, the Greater Taman Negara Landscape (c. 15,000 km2), has an existing level of protection because of the presence of rangers in Taman Negara. Both landscapes contain multiple sites with tigers and their prey species (Appendix; Laidlaw, Reference Laidlaw2002; Kawanishi & Sunquist, Reference Kawanishi and Sunquist2004). Sites that contain at least several individuals, especially breeding females, should be targeted. Priority sites include Royal Belum State Park (1,175 km2) and Taman Negara (4,343 km2), with secondary priority sites being Bintang Hijau, identified in this study, and Krau Wildlife Reserve, where tigers persist in small numbers (Laidlaw, Reference Laidlaw2002). A few tigers may persist in Endau-Rompin (DWNP, unpubl. data) but the site is of low priority because it is small (891 km2) and embedded in a heavily fragmented landscape with only tenuous connections to the Greater Taman Negara Landscape. Measures that need to be taken to restore tiger numbers to their full potential in these landscapes (Kawanishi et al., 2003) include:
Short-term actions(1) Mark-recapture studies using camera traps to obtain statistically defensible tiger density estimates at key sites. (2) Enforcement training for park rangers and staff who work outside protected areas, and implementation of anti-poaching strategies. Basic training for Taman Negara staff has been provided through the CITES Monitoring of the Illegal Killing of Elephants (MIKE) programme. People in local communities could be recruited to provide information about poaching, supplementing enforcement staff efforts. Wildlife protection strategies implemented for tiger areas elsewhere (Lynam & Soriyun, Reference Lynam and Soriyun2004; Lynam et al., 2006b) could serve as models for Malaysian sites. (3) Increased communication and collaboration between Malaysian police, customs and wildlife departments, and their counterparts in neighbouring countries would reduce trafficking of tiger products. This is central to the goals of the new ASEAN Wildlife Enforcement Network (Bazilchuk, Reference Bazilchuk2006). (4) Information should be assembled to quantify the rate at which, and reasons why, tigers are killed in Peninsular Malaysia; such information would garner public support for conservation and help mitigate future tiger-human conflicts. Alternatives to killing or removing problem tigers into captivity, such as translocating animals to other wild populations (Goodrich & Miquelle, Reference Goodrich and Miquelle2005) should be explored.
Long-term actions
(1) Many protected areas are <500 km2 and will not support viable tiger populations. New protected areas should be established in key tiger areas, and existing areas expanded. Many of the 32 protected areas proposed by the federal government between 1976–1998, if designated, could meet the requirements for tiger conservation. (2) For tigers to persist in human-dominated landscapes, areas that support breeding populations and the habitat corridors that link them must be retained (Wikramanayake et al., Reference Wikramanayake, Dinerstein, Loucks, Olson, Morrison, Lamoreux, McKnight and Hedao2004; Linkie et al., Reference Linkie, Chapron, Martyr, Holden and Leader-Williams2006). Geographic information systems and remote sensing tools can estimate rates of habitat loss, project future loss and predict creation of forest edges (Kinnaird et al., Reference Kinnaird, Sanderson, O'Brien, Wibisono and Woolmer2002). The loss of certain areas, such as corridors between Taman Negara and Krau Wildlife Reserve, and between Taman Negara and the Main Range (Fig. 1), may hinder tiger dispersal. The new Selangor Heritage Park (1,070 km2) linking all catchment areas of Selangor State to the Main Range, will help to maintain habitat linkages (Economic Planning Unit, 2006). (3) Camera-trap photographs could be used creatively to increase public awareness and motivate field staff. A tiger education programme for park rangers was introduced in 2004 using camera-trap photographs and a standard teaching curriculum (Naiman, Reference Madhusudan and Karanth2002). (4) Management Plans such as that developed for Krau Wildlife Reserve (DWNP/DANCED, 2002) should be developed and implemented for other key tiger sites.
Results of field surveys, coupled with information on specific threats in tiger areas, provide the basis for conservation planning for tigers (Lynam et al., Reference Lynam, Khaing and Zaw2006a). Information derived from this study, with the results of separate studies of tiger ecology and distribution (DWNP/DANCED, 2002; Kawanishi & Sunquist, Reference Kawanishi and Sunquist2004), collectively provide the foundation for the ongoing revision of Malaysia's National Tiger Action Plan. Information from this report has already been used to update a region-wide tiger conservation planning analysis (Sanderson et al., Reference Robinson, Redford and Bennett2006).
