Mountain chain in Cambodia

The Cardamom Mountains (, Chuŏr Phnum Krâvanh ; ทิวเขาบรรทัด, Thio Khao Banthat ), or the Krâvanh Mountains, is a mountain range in the southwest part of Cambodia and Eastern Thailand. The majority of the range is within Cambodia. The silhouette of the Cardamom Mountains appears in the provincial seal of Trat Province in Thailand.

The mountain range extends along a southeast northwest axis from Chanthaburi Province in Thailand, and Koh Kong Province in Cambodia on the Gulf of Thailand, to the Veal Veang District in Pursat Province, and extends to the southeast by the Dâmrei (Elephant) Mountains. The Thai part of the range comprise heavily eroded and dispersed mountain fragments of which the Khao Sa Bap, Khao Soi Dao and Chamao Wong Mountains, east, north and west of Chanthaburi respectively, are the most prominent. Dense tropical rainforest prevails on the wet westward slopes which annually receive from of rainfall. By contrast, only 1,000 to 1,500 mm (40 to 60 inches) fall on the wooded eastern slopes in the rain shadow facing the interior Cambodian plain, such as the Kirirom National Park. Most of the mountains are a dense wilderness, with almost no human population or activity, but on the eastern slopes, cardamom and pepper are grown commercially, and several large scale construction projects have begun since the turn of the century.

The Cardamom Mountains holds many historic sites and relics from the 15th to 17th century specifically. This includes a number of exposed burial sites of a type known as jar burials. The burials are scattered around the mountains, set out on remote, natural rock ledges, and contains 60 cm exotic ceramic jars and rough hewn log coffins. The jar burials are a unique feature of this region, and forms a previously unrecorded burial practice in Khmer cultural history. Local legends suggest the bones are the remains of Cambodian royalty. Along with these jar burials archeologists have discovered various material evidence associated with the remains such as glass beads consisting of various colors and composition. These glass beads, which were a common product within maritime trade between nearby countries, were most likely obtained by Cardamom Mountain communities by trading forest products such as wood and resin that they had access to. A unique rock art cave site known as Kanam depicts ancient elephants, elephant riders, deer and wild cow (or buffalo) in red ochre paint. The site is located in the eastern part of the Cardamoms near Kravanh Township (Pursat Province). The Cardamoms are home to one of the largest protected wild elephant populations in Southeast Asia. The human riders may represent elephant capture and training activities a major cultural tradition among various ethnic groups in the area until the 1970s. Traditions, experts, and elephant populations were decimated by the Khmer Rouge Regime. The cave and paintings may have played important roles for rituals and magic used to placate ancestors and spirits; seek protection (elephant capture is very dangerous); bring good fortune; and transmit specialized knowledge (teaching/training). Some of the paintings may be various species of wild cow or buffalo. It is difficult to distinguish the possible cow from the possible deer representations due to the simple silhouette style. However, cowhides are extremely important for lassoes, ropes, snares and riggings related to elephant capture. Local elephant masters claimed there was more ritual and magic associated with these highly critical items than all others related to elephant capture. Thus, wild cow or buffalo representation might be expected. The large representation of deer may relate to the massive deerskin trade to Japan in the 15th 17th centuries. Taiwan's deer populations had been almost annihilated due to insatiable demands for Samurai armor and Japanese accessories made of deerskin. Deerskin sourcing shifted to Cambodia and Thailand. As deer populations decreased, local hunters also may have resorted to more investment in magic and ritual to seek assistance from ancestors and spirits to increase luck. The paintings are thought to date from the late Angkorian period through the post Angkor period (contemporaneous with the jar burials, perhaps created and used by the same ethnic groups). The site may date to as early as the Funan period (1st 6th centuries) when the practice of capturing, training, and trading live elephants was first historically noted (a mission was sent to China in 357 AD with trained elephants as part of the tributary gifts to Emperor Mu of Jin). Whether or not elephant capture, training, and use for labor, prestige and warfare existed prior to the Funan period is unknown. It is possible that the practice, technology and knowledge was obtained through South Asian influence in the early first millennium AD. These paintings help with understanding the ecological history. Local ethnic groups were able to maintain, sustain and promote elephant populations through a somewhat symbiotic relation until the 20th century. Deer and wild cow/buffalo, however, may have been hunted to near extinction by the 15th 17th centuries. Eld's deer, muntjac, sambar, gaur, kouprey and banteng were probably far more prevalent in the past.

Part of the mountains are home to indigenous people, including the Chhong in both Thailand and Cambodia, and the ethnic Por (or Pear) in Pursat Province, Cambodia. They all belong to the group known as Pearic peoples. In Cambodia, indigenous people are collectively referred to as Khmer Loeu.

This largely inaccessible mountain range formed one of the last strongholds of the Khmer Rouge, driven out by Vietnamese forces during the Cambodian–Vietnamese War. The Thai border to the west acted as a conduit for Chinese support and, eventually, a sanctuary for fleeing Khmer fighters and refugees.

The inaccessibility of the hills has also helped to preserve the primeval forest and ecosystems of the area relatively intact. In 2002, however, a transborder highway to Thailand was completed south of the Cardamoms, along the coast. The highway has fragmented habitats for large mammals such as elephants, big cats and monkeys. The highway has also opened up for agricultural slash and burn projects and opportunistic poaching for endangered animals, all degrading the natural value and the forests ecosystems. Tourism is relatively new to the Cardamom Mountains. In 2008, Wildlife Alliance launched a community based ecotourism program in the village of Chi Phat, marketed as the "gateway to the Cardamoms". Tourist visitors to Chi Phat continue to grow and the community is regarded as a model for community based ecotourism, with approximately 3,000 annual visitors generating more than $US 150,000 for the local community. International conservation organizations working in the area includes Wildlife Alliance, Conservation International, and Fauna and Flora International. In 2016, the southern slopes of the Cardamom Mountains were designated as a new national park; Southern Cardamom National Park.

These relatively isolated mountains are part of the Cardamom Mountains rain forests ecoregion, an important ecoregion of mostly tropical moist broadleaf forest. Most of the ecoregion is covered in evergreen rain forest, but with several different habitats. Above 700 metres, a special thick evergreen forest type dominates, and on the southern slopes of the Elephant Mountains, dwarf conifer Dacrydium elatum forests grows. On the Kirirom plateau, Tenasserim pine forest is found. The northern part of Cardamom Mountains is home to the southernmost natural habitats of Betula (species Betula alnoides). Throughout, Hopea pierrei, an endangered canopy tree rare elsewhere, is relatively abundant in the Cardamom Mountains. Other angiosperm tree species are Anisoptera costata, Anisoptera glabra, Dipterocarpus costatus, Hopea odorata, Shorea hypochra, Caryota urens and Oncosperma tigillarium. Other conifers include Pinus kesiya, Dacrycarpus imbricatus, Podocarpus neriifolius, P. pilgeri and Nageia wallichiana.

The moist climate and undisturbed nature of the rocky mountainsides appears to have allowed a rich variety of wildlife to thrive, although the Cardamom and Elephant Mountains are poorly researched and the wildlife that is assumed to be here remains to be catalogued. They are thought to be home to over 100 mammals such as the large Indian civet and banteng cattle, and most importantly the mountains are thought to shelter at least 62 globally threatened animal species and 17 globally threatened trees, many of them endemic to Cambodia. Among the animals are fourteen endangered and threatened mammal species, including the largest population of Asian elephant in Cambodia and possibly the whole of Indochina although this still needs to be proved. Other mammals, many of which are threatened, include Indochinese tiger, clouded leopard (Pardofelis nebulosa), dhole (a wild dog) (Cuon alpinus), gaur (Bos gaurus), banteng (Bos javanicus), the disputed kting voar (Pseudonovibos spiralis), Malayan sun bear, pileated gibbon (Hylobates pileatus), Sumatran serow (Capricornis sumatraensis), Sunda pangolin and the Tenasserim white bellied rat. There are at least 34 species of amphibians, three of them described as new species to science from here. The rivers are home to both Irrawaddy and humpback dolphins and are home to some of the last populations on Earth of the very rare Siamese crocodiles and the only nearly extinct northern river terrapin, or royal turtle remaining in Cambodia. While the forests are habitat for more than 450 bird species, half of Cambodia's total of which four, the chestnut headed partridge, Lewis's silver pheasant (Lophura nycthemera lewisi), the green peafowl (Pavo muticus) and the Siamese partridge (Arborophila diversa) are endemic to these mountains. A reptile and amphibian survey led in June 2007 by Dr Lee Grismer of La Sierra University in Riverside, California, US and the conservation organisation Fauna and Flora International uncovered new species, such as a new Cnemaspis gecko, C. neangthyi.

With the establishment of the Southern Cardamom National Park in May 2016, nearly all of the Cardamom Mountains are now under some form of high level protection, mostly national park area and wildlife sanctuaries. However, the level of active protection has been criticised. Despite the very high level of protectional status, the actual protection of the conservation areas and implementation of the law has been very poor. The violation of the protection laws has happened on all levels, from opportunistic locals, and local business entrepreneurs, to governmental institutions, foreign companies and international criminal organisations. In the late 2010s, international conservation organisations, and the UN, has collaborated with the Cambodian government to halt a number of planned construction projects and clearings in protected areas. In 2016, the Cambodian government established a collaboration with international conservation organisations to increase on ground patrolling and actual park ranger services, building several ranger headquarters and hiring armed personnel with arresting rights. This might signify a change in the destructive trends, at least concerning governmental responsibilities.

The Cardamom Mountains are an emerging tourist destination. The village of Chi Phat runs a Community Based Eco Tourism project with the support of conservation NGO, Wildlife Alliance. Previously a logging and hunting community, villagers now make sustainable income through homestays, multiple day guided treks to natural and cultural sites, mountain bike, boat and bird watching tours. The Wildlife Release Station in Koh Kong Province is a release site for animals rescued from the illegal wildlife trade in Cambodia by the NGO Wildlife Alliance. Binturong, porcupine, pangolins, civets, macaques and an array of birds are among the many species that have been released on site. The station was opened to tourists in December 2013, offering guests an insight into the workings of a wildlife rehabilitation and release site while staying in jungle chalets and enjoying Cambodian hospitality. Activities offered can include feeding resident wildlife, jungle hiking, radio tracking and setting camera traps to monitor released wildlife. Wild Animal Rescue (WAR Adventures Cambodia) also organize a wide range of deep jungle activities from the family trekking to the hardcore RAID adventure, jungle orientation and survival training course, even animals and human tracking course, all in the region of Sre Ambel in the South west of the Cardamom mountains.
