The Indochinese Serow is a stealthy forest dweller, somehow lacking the attractiveness of its neighbours the Chinese Serow with its heavy, silvery mane or the Sumatran Serow to the south which can emerge with a jet-black pellage.

The Indochina Serow is slightly larger than the Sumatran Serow. (5) The Sumatran Serow is overall black. The Chinese Serow is slightly bigger, has a heavier mane and the red of its legs is more obvious.
Distribution
By countries (in alphabetical order): Cambodia, Lao People’s Democratic Republic, Myanmar, Thailand, Viet Nam (2).
Some authers draw the distribution boundary between the Chinese Serow and Indochinese Serow close to the political boundary between China and Myanmar, Laos and Vietnam. (1) It is uncertain, but likely, that the distribution ranges of the Chinese Serow, the Indochinese Serow and the Red Serow (C. rubidus) meet or overlap in Myanmar, Shan States (upper Salween River). However, Rabinowitz (1998) reported that the Red Serow and the Indochinese Serow distribution ranges do not overlap in Myanmar. (1)
In Cambodia the species is probably naturally restricted to the hill and mountainous terrain that surround the Mekong and Tonle Sap (lake) central plains (Gray and Phan 2011, Gray et al. 2017). (6)
in Lao PDR the historic distribution of the taxon almost certainly included the vast majority of the countries, the majority of which is hilly to mountainous (Lekagul and McNeely1988). Currently in Lao PDR the species is restricted to rugged terrain areas, especially along the Annamite mountain range of eastern central and southern Lao PDR (Vongkhamheng et al. 2013, Tilker 2014). (6)
In Myanmar the general distribution appears to follow the forested mountain ranges surrounding the central plains. Its distribution in the northwest is believed to stretch through the Chin Hills from the border with India, probably as far south as 20ºN in the Arakan Yoma range. A larger distribution area occurs in the mountains in the north (Kachin state) and in the mountains east of about 96ºW, to Myanmar’s borders with China, Lao PDR and Thailand. (6) This species may or may not be sympatric with Capricornis rubidus in Myanmar (Than Zaw and W. Duckworth pers. comm. 2006). (2)
Thailand: The IUCN does not recognise Capricornis milneedwardsi maritimus. They write the following for the region: „Two subspecies (C. s. sumatraensis and C. s. milneedwardsii) originally were widely distributed throughout Thailand, but they are now restricted to steep, forested limestone hills and cliffs, in areas relatively inaccessible to human encroachment (Lovari, 1997). Therefore, their populations are highly fragmented, with a low density (Lovari 1997, Lyam et al. 2006, Steinmetz et al. 2009). The dividing line between the ranges of C. s. milneedwardsii and C. s. sumatraensis is unclear, but it is suspected to fall somewhere in the Chooporn (spelled „Chumphon“ on google maps) or Suratchathani Provinces (Grubb 2005) (6) or the Kra Isthmus (3). In the Koh Lak peaks, Kloss said, that the Indochinese Serow lives in association with animals in which the lower legs are almost entirely black. This suggests that there may be either hybridization or, less likely, sympatry with the Sumatran Serow. (4)
In Vietnam the serows were recorded in almost all protected areas from northern to the south-central areas of the country, especially where forested limestone mountains and cliffs occured (Nguyen Xuan Dang and Le Xuan Canh 2009). During mammal surveys from 1999 to 2008, serows were found in northern Vietnam, including Ha Giang, Cao Bang, Lai Chau, Tuyen Quang, Bac Kan, Phu Tho, Thai Nguyen, Vinh Phuc, Quang Ninh, Hai Phong, Hoa Binh and Ninh Binh provinces; in the northern central areas of Vietnam, such as Thanh Hoa, Nghe An, Ha Tinh, Quang Binh, Quang Tri, and Thua Thien Hue; in the central areas of Viet Nam, including Quang Nam, Kon Tum, Gia Lai, Dak Lac, Dak Nong and Lam Dong provinces, and in the southern central areas of Vietnam, including in Binh Dinh, Binh Thuan and Ninh Thuan provinces (Dang Ngoc Can et al. 2008). The species has also been recorded from offshore islands in the north, e.g. Cat Ba (Phan et al. 2014). However, there is no further information available on its distribution status and it is believed that this sub-species has significantly declined due to poaching in Vietnam. (6)
General description
length / head-body: 140-155 cm (3). The Chinese Serow (C. milneedwardsii) is slightly bigger. (1)
shoulder height: 85 to 94 cm (3)
weight: 85-140 kg (3)
pelage: black or dark brown (4), brownish (1), but it appears gray or brindled because of white hair bases (4). The coat is supposed to be thicker and wollier compared to the Chinese Serow (1).

Hard to believe, but the coat in Indochinese Serow is supposed to be thicker and wollier compared to the more northerly living Chinese Serow. In this Juvenile from Khao Yai National Park, Thailand, this seems to be extraordinarly thick. Note also the rust-coloured spot on the muzzle, which has previously not been described for this species. Photo: Tontan-Travel, www.tontantravel.com
underparts: darkish (3), often black, not white (4); (in Chinese Serow: paler)
dorsal stripe: dark mid-dorsal stripe (3), usually thin, but sometimes thick (4); median stripe of allblack hairs extends down the back to the basal half of the tail. (1)

mane: short, with blackish and brownish hairs (1), often predominantly white because of mixed black and white or pale yellow-buff hairs. (3) In the Chinese Serow the mane is heavier. (1)
tail: 11-16 cm (3); the tail is supposed to be bushier compared to the Chinese Serow (1).legs: The upper half of the legs are jet black and the lower half are reddish tan or creamy, with a sharp division inbetween; sometimes a white or red patch on the carpus, and a black mark or mingling or line on the lower shanks. (4) The red of the legs is not as obvious as in the Chinese Serow.
head / face: white lips and a white moustache mark; white or golden brown throat or collar, sometimes forming a large patch (1, 3, 4)

ears: long: 12,3-13,2 cm (Chinese Serow: 11,7-13,3) (4); insides of the ear are whitish to tawny. (1)
Horns
horns are flattended transversely at the base and laterally in the distal half, converging slightly at the tips. Only one head has ever been registered as a hunting trophy. It was taken in 1927 (Indochina) with the longer horn measuring 15,9 cm and with a circumference of 11,4 cm and a tip-to-tip spread of 8,3 cm. (1)
Habitat
The IUCN does not differentiate between Mainland Serow and Indochinese Serow. This is what they write for the Mainland Serow (information concerning the Indochinese Serow is highlighted in blue):
The Mainland Serow is a forest dwelling mammal, and inhabits mountain slopes with rugged steep hills and rocky places from 100 m to 4,000 m (Li et al. 2014, Phan et al. 2014, Paudel et al. 2015, Buzzard et al. 2018, McShea et al. 2018). It is also recorded in temperate coniferous forests and broadleaved forests in Nepal (Paudel et al. 2015) and northwest Yunnan, Southwest China (Buzzard et al. 2018) and in the dense thickets of Rhododendron and Vaccinium in Vietnam (Abramov et al. 2006). It also inhabits lowland montane forests with gentler terrain, including flat areas with shrubs (Li et al. 2012). The serow occurs also on small offshore islands, such as Cat Ba Island in north Vietnam (Phan et al. 2014) and coastal small islands along the Northern Peninsula in Thailand (S. Lovari pers. comm). (6)
While mainland serows are sensitive to human disturbance, they seem to tolerate moderately degraded forests and small isolated limestone hills and cliffs in both natural karst scrubland and even disturbed habitats (Lekagul and Mcneely 1988). Studies have found that serow occupancy is positively correlated with distance to roads, distance to villages and distance to trails indicating its preference for areas inaccessible to human encroachment (Li et al. 2012, Phan et al. 2019). The serow prefers closed canopy habitats to open ones, at relatively high altitudes in coniferous and rhododendron forests (Li et al. 2014, Buzzard et al. 2018). However, the species prefers open canopy to closed canopy, in low altitude limestone forests (Phan et al. 2019). (6)
The species feeds on a wide range of leaves and twigs of at least 33 different plant species in the Cat Ba Island, Vietnam (Phan et al. 2012). Most of these plant species are shrubs and low growing trees and thus serow is categorised as a typical browser. (6)
The Mainland Serow is active at almost any time, especially at dawn (Li et al. 2018b). They shelter under overhanging cliffs and rocks Lovari and Locati 1984). This species may naturally occur at rather low density, compared to other sympatric bovid species such as Goral and Takin (McShea et al. 2018). It is mostly solitary and probably territorial (McShea et al. 2018), marking the boundaries of its territory e.g. with dung piles (Lovari and Locati 1994). Several individuals are sometimes seen in the same area, but they feed some distance apart (Lekagul and McNeely 1988). (6)
The Indochinese Serow occurs in rugged limestone mountains and cliffs. In Vietnam, it is usually found above 1500 m in steep montane scrub, evergreen hill forests, and grassland slopes. But the species also occurs in lowland forest (3) and on small offshore islands and has been reported swimming between them (Duckworth and Walston 1998). (2)
In Cambodia it appears to occupy small, naturally isolated karst limestone outcrops in the level lowlands of the Mekong plains (R. Timmins pers. comm. 2008). (2)

It is likely to tolerate moderately degraded habitat well, due to its presence in natural karst scrubland, though it is unlikely to be present in heavily disturbed areas such as agricultural land (W. Duckworth pers. comm. 2006), and has been documented amidst secondary forests and swidden in at least one landscape mosaics of such habitats and ‘primary’ forest (W. G. Robichaud in litt. to R. Timmins pers. comm. 2008). The species also appears to persist well in small habitat isolates, both naturally (i.e. Cambodia; R. J. Timmins pers. comm. 2008) and due to habitat loss (i.e. Thailand; Lekagul and McNeely 1988). (2)
In February 2026 I went to Thailand to look at three sites, where Indochinese Serows are more or less regularly seen. The one location is in the Pak Chong area, just outside Khao Yai National Park. This is what the situation looks like on the ground at Pak Chong:
Geomorphology / geology of the Pak Chong serow habitat
There are numerous tropical karst hills (the height of one measured at 510 metres), that are composed of limestone and represent the remnants of a once compact sedimentary layer. The surrounding area is essentially a plain (380 m above sea level) with the hills embedded within it. They are gradually being eroded by solution weathering, a process clearly visible in the so called karren that can be seen on the rocks.

Top of the hill, where serow show up from time to time: solution weathering has left karren (vertical grooves) in the limestone surface. This makes the rocks sharp-edged, which contributes to the hill being inaccessible. Photo: Bürglin
The sharp-edged rocks and the dense vegetation make the karst hills relatively inaccessible, which is certainly advantageous for the serows. On the other hand these hills are small, the one measuring just 600 meters in diameter at its base.

Google earth screenshot of the area: single hills are embedded in a plane that is quite heavily populated. The connectivity between the hills and the Khao Yai national park (in the background) seems to be still given. Photo: Bürglin

A rather inconspicuous road sign seems to indicate that the serows also cross the road. Photo: Bürglin
Plant-community-wise the Pak Chong area is within the “Mixed Deciduous Forest”-zone. At the end of February, it seems that the dry season has already begun. Many trees have shed their leaves to leave the canopy looking open.
So why would the serows come here at all? Serows are heavily poached animals in Thailand (This is why I don’t want to disclose the exact location here.) They should be safer in the core area of the national park. The expansive forest of Khao Yai isn’t far away. The karst hills in the foreland can be seen as inselbergs. The connection to the park’s source area should still be relatively good.
Maybe the answer is to be found in the biology of the serow. Females of many ungulate species are known to isolate themselves for the birth of their young and the initial period afterward. One reason is that living in seclusion offers protection for a still helpless youngster. More individuals are easier to be seen. During my visit, a serow mother with a young could be seen on the mountain – I was told by locals–, specifically in the rocky summit area, from sunrise until about 9:30 a.m. So maybe the urge for seclusion counts also for the serow. But why they show up at this time of the day is another mistery.
Why do the serows show up at sunrise?
Some speculate that they come around this time to warm up. In photos, it does indeed look as if they were basking in the sun. But to warm up? Even in February – when we were there – temperatures hover around 30°C, and it hardly cools down at night. At sunrise, the air is pleasant. And serows are large animals, weighing between 85 and 140 kg. They don’t cool down that quickly. It’s also conceivable that basking serves to control parasites: The warmth could at least limit the activity of ectoparasites such as ticks, lice, or mites. Furthermore, basking could be important for vitamin D synthesis: Vitamin D in the skin is essential for bone health and strengthening the immune system.
The serows at Pha Diew Dai

The viewpoint at the Phao Diew Dai cliff overlooking Khao Yai National Park.
The second serow site I visited during my 2026 Thailand trip is the “Pha Diew Dai” lookout. (It is also spelled “Pha Dieu Dai” and in some other variations.) There is a cliff, which is accessible by a 446 metre loop-trail and board walk that will take 30 minutes to complete.

The board walk to Pha Diew Dai cliff. The vegetation is very dense. Serows show up once in a while along the board walk. Photo: Bürglin
Geology / geomorphology of Pha Diew Dai
With 1150 metre Pha Diew Dai cliff is the highest viewpoint with the furthest views in Khao Yai National Park.The highest points in the surrounding area are Khao Khiao (1292 m) and Khao Rom (1351 m). The rocks in the area are of the Phra Wihan formation, which comprises fine- to coarse-grained sheet and channelled sandstone beds and rarer variegated siltstone and mudstone. The thick rock layers show cross bedding, clear evidence of watercourses changing direction in the past. Intermittent conglomerate beds also show that the sediments were deposited in a fluvial environment. The cliffs were formed by headward erosion caused by the river flowing below. The cliff at Pha Diew Dai runs north-south and faces west. However, it continues and forms a larger cliff complex with varying exposures (photo).

The cliff area consists of rocks that offer the serows opportunities to retreat and hide from predators. In some places the cliff is +20 metres high.

Pha Diew Dai cliff is not just one cliff point, but rather a cliff system, that meanders along the sandstone plateau.
Micro climate: The temperatures in Khao Yai above 1.000 metres are noticeably cooler, which causes water to condense from the humid air, creating fogs which keep the soil moist and feed the streams.

Open water near Pha Diew Dai could be one reason, why serows come to the site. Someone had installed a camera at this location (above and to the right of centre). Photo: Bürglin
Plant communities / ecology: The area lies within a zone of “lower hill evergreen forest” also called “lower montane rain forest”, where one can find tropical plants like creeping bamboo, but as well temperate species distinctive of the higher elevations of Thailand. Hill evergreen forest is usually found on mountain-sides at altitudes greater than 1.000 metres. It is a dense forest type with some trees exceeding 30 metres in height, although there is less growth of epiphytic plants in the canopy and a thinner layer of humus on the forest floor in comparison with evergreen forest at lower altitudes. The dominant trees are “oaks” (Quercus sp., Lithocarpus sp. and Castanopsis sp.) as well as podocarps such as Podocarpus neriifolius, Nageia wallichiana, and Dacrydium elatum. “Thalo” or Needlewood (Schima wallichii) and the False Yew (Cephalotaxus mannii) are also found. Examples for temperate forest plants are fructicose lichens, climbing bamboos, Old Man’s Beard, Sphagnum Moss, Delavay’s Rhododendron (Rhododendron delavayi), and Agapetes saxicola.
In the vicinity of the cliff there is also a section of a unique high altitude swamp forest. This forest type needs a reliable water source all year round and is quite rare in Thailand. Typically it is found along creeks or in bogs covered with “Samet Daeng” (Syzygium gratum var. gratum) and “Toei Nam”, the Screw Pine (Pandanus sp.).
Serows and their habitat in Khao Yai National Park – according to the National Park’s website: Serows prefer living solitary on mountains, able to move nimbly on the cliffs. They are highly territorial and have regular defecation spots. They never graze far from their resting spaces, in the evening and in the morning. They eat grasses, ferns, leaves and shoots. By day they hide in the undergrowth or under overhanging rocks, and so are hard to find. (www.khaoyainationalpark.com/en/discover/fauna/mammals). It is not known if the serows use the cliff in general or just the viewpoint area. The cliffs in general offer opportunities for retreat and hiding from predators. The bog near the lookout could play a role as a place to get water and because preferred food plants could be found there. The boardwalk area could, in turn, play a role as a „human shield“.
The third serow site I visited during my 2026 Thailand trip is Khao Sam Roi Yot.

Serow habitat at Khao Sam Roi Yot limestone cliffs
We head in a boat towards the limestone cliffs and learn that the guides only get to see the serows from the water every few weeks. We are at sea level; the „serow hills“ are around 500 meters high, densely vegetated, but also interspersed with rocks. This shows once again that serows don’t necessarily need high-altitude mountains, but rather forested areas on steep terrain where they can retreat among inaccessible rocks.
Food and feeding
no specific information available, but in general, serows are browsers that consume shoots, leaves, and perhaps some gras on occasion (3)
Breeding
The breeding season occurs on late October and November, and a single kid is born after a seven-month gestation period and will stay with its mother for almost a year (Lekagul and Mcneely 1988). (6)
young per birth: presumably twins are rare (3)
Activity patterns
Serows in general are usually crepuscular, with most activity at dawn and dusk (3)
Movements, home range and social organisation
Other serows are found to live alone or in small groups (3)
Population / threats
Currently, the Mainland Serow – including the Indochinese Serow – is facing two main threats, i.e. over-poaching and habitat loss. Over-poaching, especially using snares to supply local and regional markets with meat, horns and other body parts has caused a rapid decline of this species in Southeast Asia (Steinmetz et al. 2010; Shepherd and Krishnasamy 2014; Leupen et al. 2017). Forest encroachment and clearance in protected and non-protected areas where this species exists are likely to have had a significant impact. In addition, most of the plant species consumed by the serows are medicinal herbs and edible sources for humans and thus they have been massively exploited by local people (Giri et al. 2011; Phan et al. 2012). These threats may determine a decrease in the numbers of serows and an increase in the fragmentation of populations, causing high risks of local extirpations over its range. (6)
The Indochinese Serow is extensively hunted for meat, bones, and live specimens and is relegated to small, fragmented populations. (3)
In Cambodia the population status of this subspecies is unknown and serows are probably naturally restricted to the hilly and mountainous terrain that surround the Mekong and Tonle Sap central plains. An intensive camera-trap survey was conducted within Phom Prich Wildlife Sanctuary in eastern Cambodia in 2008 and 2009, and 23 species were recorded, including four large ungulate species but serow was not recorded (Gray and Phan 2011). In addition, camera-trap detection levels of this sub-species were low and restricted to the Cardamoms, south-west Cambodia and Virachey National Park, north-eastern Cambodia (Gray et al. 2017). (6)
In Cambodia, logging, hunting, habitat loss and vast numbers of landmines are the main threats to the species. Illegal commercial hunting, particularly snaring, remains the major threat to the ground-dwelling mammals in Cardamom Rainforest Landscape and is possibly impacting populations of most such species in the landscape (Gray et al. 2017). The removal of more than 109,000 snares from the Southern Cardamom National Park and Tatai Wildlife Sanctuary between 2010 and 2015 was hard evidence of the risks which serows may face (Wildlife Alliance, unpublished data). In addition, local law enforcement is also minimal (Gray et al. 2017). Cambodia has also experienced the most rapid deforestation rate globally, between 2001 and 2014, and approximately 1,150 km² of the protected areas in Cardamom Rainforest Landscape have been lost to Economic Land Concessions for industrial agriculture (Davis et al. 2015), thereby reducing the mountainous habitat for mammals, including the serow in the whole country (Gray et al. 2017). (6)
In Lao PDR, data on population size and trend of this sub-species are unavailable. However, the sub-species showed a low detection rate in camera-trap surveys in Xe Sap National Protected Area, in southern Lao PDR (Tilker 2014) and has a density of 0.22 individual/km² in Nam Et-Phou Louey National Protected Area in northern Lao PDR (Vongkhamheng et al. 2013). In addition, this sub-species is potentially considered at risk in Lao PDR (Duckworth et al. 1999). (6)
In Lao PDR, serow horns, skull bones, leg bones and other body parts are used for traditional medicine and were recorded in 59 shops, and these items should be derived from a minimum of 150 serows (Leupen et al. 2017). There is a cross-border trade in almost all parts of the serow from Lao PDR to Thailand, Vietnam and China. However, the effects of this entire disturbance are unknown in Lao PDR (Salter and Phanthavong, 1997; Duckworth et al. 1999). (6)
In Thailand, the population and status of this sub-species is unknown and showed a low detection rate in camera-trap surveys, in Dong Phayayen – Khao Yai Forest Complex, in southern Thailand (Lyam et al. 2006). Serows had a very low detection rate in Kuiburi National Park, in south-western Thailand (Steinmetz et al. 2009) and in Thung Yai Naresuan Wildlife Sanctuary, in western Thailand (Steinmetz et al. 2010). (6)
In Thailand, loss of habitat caused by logging and land clearing for agriculture, and poaching for meat and medicinal purposes are the major threats for this species (Lovari, 1997). In addition, poaching for the trade in trophies (skins and horns), and the collection of non-timber forest products also negatively impact on the species and damage its habitat, which has resulted in the species being threatened in almost all forested areas in Thailand (Lyam et al. 2006). Furthermore, the remaining habitat for wildlife in Thailand is highly fragmented presently and mostly too small to support viable populations of wildlife species (Lyam et al. 2006).
In Vietnam, population numbers are unknown, an exception being about 26 individuals left in the Cat Ba Island, in north Vietnam (Phan et al. 2014). This sub-species was recorded in almost all protected areas from northern to southern central areas of Vietnam, but populations are small and scattered, and numbers are probably low (Nguyen Xuan Dang and Le Xuan Canh, 2009; Dang Ngoc Can et al. 2008). It is believed that populations in the northern highlands are heavily depleted in number and the populations are highly fragmented. However, they are likely to be more present in most protected areas along the Annamite mountains of central Vietnam. For example, five monitoring programs used 591camera traps in Pu Mat National Park in central Vietnam and recorded 94 photos of serows from 2016 to 2018 (Tran Xuan Cuong pers. comm. 2019). (6)
In Vietnam, the serow is frequently hunted for bush meat and for commercial purposes. Vietnam is a significant consumer of wildlife meat, including serow and thus wild meat is sold in many local markets and serow bones are purchased to make medicines (Shairp et al., 2016; Nijman and Shepherd, 2017). Over 23,000 snares were discovered and removed by forest rangers in Hue-Quang Nam Saola Reserve in 2015 (Gray et al. 2018). The result of this hunting is a significant decline in the populations of this species in almost all protected areas in Vietnam (Do Tuoc. pers. comm. 2011). (6)
In Myanmar, too, the major threats to the serow include hunting, poaching, habitat degradation, and loss from deforestation. Wildlife items are widely used in the local pharmacopeia, and serow items were recorded for sale in 25 medicine shops in Mon State, south Myanmar (Nijman and Shepherd 2017). Habitat degradation and deforestation are the main consequences of human activities such as timber harvesting and agriculture, and fires in the country (Salter and Shackleton 1997).
Conservation Status / Action
The Mainland serow – including the Indochinese Serow – is listed in Appendix I of the CITES (The Convention of International Trade in Endangered Species of Wild Fauna and Flora), which prohibits international commercial trade of the species, its body parts and derivatives. (6)
It seems that there is no actual legislation aimed at conserving the serow in Cambodia, Myanmar and Thailand. In Vietnam, the animal is listed as IB (hunting prohibited) in the Endangered and Rare Species List in Degree 32, in 2006, and Endangered (E) in the Vietnamese Red Book, in 2008. (6)
So far, there have been just a few research projects focused on the distribution and status of serows throughout its range, except several studies, e.g. in Cat Ba Island, Vietnam (Phan et al. 2014) and in Annapurna Conservation Area, (Aryal, 2008). Camera-trap surveys were conducted by conservation organisations (e.g. WWF, FFI and WCS) in protected areas throughout Southeast Asia to monitor and assess the distribution status of wildlife animals, including serows. For example, in Vietnam, WWF cooperated with Song Thanh Nature Reserve and Bac Hai Van Nature Reserve to monitor wildlife animals through establishing camera-traps, and recorded the presence of serows in these reserves (Mai Sy Luan pers.comm. 2020). Similarly, FFI and SVW conducted a camera-trap survey in Pu Mat National Park to monitor wildlife and recorded the evidence of serows (Tran Xuan Cuong, pers.comm. 2020). (6)
In Cambodia legislation (State Council No. 35 KR.C, Law Decree on Forestry) governs the use and management of forests and wildlife, and stipulates penalties for contravention. However, this legislation is only interim and is generally unenforceable. It is also only very general in scope and does not specifically include serow. Protection of serow lies within the Forestry Department of the Ministry of Agriculture, and more specifically with the newly-created Wildlife Protection Office. Serow was known to occur only in Phnom Kravanh protected area, but this is located in a region which saw military conflict between 1980 and 1982, and possibly more recently. (2)
Conservation measures proposed for Cambodia: 1) Determine the serow’s distribution and status in Mondulkiri Province. The Forestry Department planned to begin these censuses as soon as it became safe and feasible. International support will be required to fund both the census studies and the development of the subsequent conservation plans. 2) The Cambodian Government should create a broad conservation strategy, including a network of protected areas and supporting infrastructure to protect all the country’s natural resources. The species likely occurs widely in the Cardamom range of the southwest, which is now well covered by national protected areas, and conservation management in several of these areas is already ongoing and starting to effectively control hunting (R. Timmins pers. comm. 2008). The species also likely occurs in several other areas of the country covered by protected areas, namely Rattanakiri province in Virachey NP and Mondulkiri Province (R. Timmins pers. comm. 2008). Given Cambodia’s exceptional concentration of highly threatened species, conservation of serow should not be considered a high priority nationally, and with effective conservation management of suitable protected areas, the species should be safe without the need for species specific conservation activities (R. Timmins pers. comm. 2008). (2)
In Vietnam the serow is included in Appendix II of the Endangered and Rare Species List of the country. However, it is not included in the list of 38 species covered by Declaration No. 276 of the Ministry of Forestry (2 June 1989) and Decision No. 18 HDBT of the Council of Ministers (17 January 1992) so serow can be hunted or captured. The species has been recorded from many protected areas and likely occurs in many others with extensive tracts of suitable habitat, the most significant populations remaining are likely to be found in the extensive tracts of habitat covered by protected areas in the Annamite (Truong Son) mountain chain, especially the extensive limestone formations of the central region and limestone formations in the north (R. Timmins pers. comm. 2008). Effective management of suitable protected areas, especially controlling hunting, should be sufficient to conserve the species nationally, however, the majority of areas are still fall well below this level of management, although there is cause for optimism within a few (R. Timmins pers. comm. 2008). (2)
In Myanmar, serow occur in Kahilu (an area of armed civil unrest, which suffers from poaching) and Kelatha Hill Game Sanctuaries, and in Shwesettaw and Shwe-U-Daung Wildlife Sanctuaries. It also probably occurs in Tamanthi, Pidaung, and Mulayit Wildlife Sanctuaries. Serow is also reported in a number of proposed National Parks: Alaungdaw Kathapa, Kyaukpandaung, Natma Taung and Pegu Yomas. Serow was eliminated from Taunggyi Wildlife Sanctuary, probably as the result of poaching and hunting by domestic dogs (IUCN, 1992b; WCMC, 1987).
Conservation measures proposed for Myanmar: 1) Carry out surveys and censuses to develop conservation programs. 2) Immediate enforcement of protection against poaching, especially in protected areas. (2)
In Thailand the serow is also protected. It is known or expected to occur in the following protected areas: National Parks – Chaloem Rattankosin (Than Than Lot); Doi Inthanon; Doi Khuntan; Erawan; Khao Chamao-Khao Wong; Khao Luang; Khao Pu-Khao Ya; Khao Sam Lam; Khao Sam Roi Yot; Khao Yai; Nam Nao; Namtok Phliu (Khao Sabup); Phu Kradung; Rhamkhamhaeng; Si Nakarin; Si Satchanalai; Thaleban and possibly Ao Phangnga. WiZdZifi Sanctuaries – Doi Chiang Dao; Doi Pha Muang; Huai Kha Khaeng; Khao Banthat; Om-Koi/Mae Tun; Maenam Phachi; Phu Khieo; Phu Luang; Phu Miang-Phu Thong; Salawin; Thung Yai Naresuan; Tong Nga Chang.
Conservation measures proposed for Thailand: Determine the serow’s status to assess the effects that logging and poaching are having on its distribution and numbers. (2)
