Doi Inthanon Summit

          The topographical features are that of fold mountains (complex mountain landscape), which extend Thanon Thongchai Mountain range north-south from Himalayas Mountain range in Nepal. The area is located between 400 and 2,565 meters above sea level with the Doi Inthanon summit being Thailand's highest summit. Doi Hua Mot Luang, at 2,330 meters, is the second highest mountain summit, Doi Hua Mot Noi reaches a height of 1,900 meters andDoi Hua Suea's summit is 1,881 meters above sea level.
Doi Inthanon National Park's geological structure is largely composed of Cambrian-era stones, with the rocks being Gneiss and Granite. Other rocks, including limestone, are found in the Ordovician. It lasted until the Terry era, with the exception of round pebbles. 

        Doi Inthanon National Park is a significant catchment area for the Ping River and the source of a number of rivers and streams. The Mae Wang Stream, Mae Klang Stream, Mae Ya Stream, Mae Hoi Stream, Mae Chaem Stream, and Mae Tia Stream are all significant rivers which flow through and nourish the communities of Chiang Mai Province's Chom Thong, Mae Chaem, Hot, Mae Wang, and San Pa Tong District.

       The Doi Inthanon National Park's general climate is influenced by the southwest monsoon, which brings moisture and rain clouds. Additionally, the northeast monsoon, which originates in China, brings cold and drought. It results in distinct seasons, with summer lasting from March to May, a rainy season lasting from June to November, and winter lasting from December to February. However, due to Doi Inthanon National Park's altitude diversity, the weather characteristics in each area vary significantly.

       It is characterized by a tropical climate in the lower part of the area where the altitude is lower than 1,000 meters above sea level. The subtropical climate in the middle of the area with an elevation above sea level of between 1,000-2,000 meters and has a temperate climate in areas with an altitude of more than 2,000 meters above sea level.

       The upper highlands of the National Park are generally wet and cold throughout the year. Particularly at the summit of Doi Inthanon, which has the appearance of a ridge and a mountain summit. There may be gale-force winds and subfreezing temperatures. Additionally, during frosty days in December and January, the temperature may fall to 0-4 degrees Celsius, resulting in frost. At the park's central region, the climate is generally cool and humid. Throughout the year, the average temperature is around 20 degrees Celsius. During the winter months of December and January, the average temperature is between 15 and 17 degrees Celsius. The average annual rainfall is between 2,000 and 2,100 millimeters. At elevations of 1,800 meters and higher, a cool, wet climate prevails. This is because the low clouds cause the forest to be clouded and foggy for the majority of the year.

       The ecosystem in the Doi Inthanon National Park area can be divided into the following categories:
           Deciduous dipterocarp forests are scattered throughout the National Park between 400–750 meters on parched hills or ridges. and mainly on western and southern slopes. Wood species includeBurma Sal, Burmese Sal, Hairy Keruing, Dipterocarpus tuberculatus, Quercus kerrii Craib, Terminalia alata Heyne, Melanorrhoea ustata, Morinda coreia, and Phyllanthus emblica, among others. Additionally, there are mosses, lichens, Hoya ovalifolia Wight, and Pyrrosia piloselloides on the as well as various grasses, vines, and biennial plants. At an elevation of 400 to 800 meters above sea level, mixed deciduous forest is found scattered throughout the National Park. Teak, Lagerstroemia calyculata, Burma Padauk, Xylia xylocarpa, Canarium subulatum, Terminalia chebula, Vitex peduncularis, Balakata baccata, Irvingia malayana, Gamari, and various types of bamboo, as well as epiphyte plants such as Rhynchostylis gigantea, Rhynchostylis coelestis, and others are The majority of plants on the lower ground are shrubs and grasses, such as Imperata cylindrica, Chrysopogon zizanioides, vines, and other annuals.

        The dry evergreen forest is found scattered in small patches at an altitude of 400-1,000 meters along the valley, along the creek, and at Sop Huai. The plants are found include Dipterocarpus costatus, Dipterocarpus turbinatus, Dipterocarpus alatus, Hopea odorata, Evergreen Chinkapin, Castanopsis argyrophylla King, Castanopsis indica, Javan Cedar, Baccaurea ramiflora Lour, Syzygium siamensis Craib, Ficus benjamina, and Meliosma simplicifolia,he ground plants prefer high humidity and include Musa acuminata Colla, Desmodium velutinum, Symplocos sumuntia Buch, Phrynium pubinerve Blume, Boesenbergia rotunda, Alpinia conchigera, Sessile Joyweed, Osmunda spp, Diplazium esculentum, ferns, Palmae, Calamus palustris var. palustris, Chinese Evergreen, and Wallichia caryotoides.

           The lower hill evergreen forest occurs between 1,000 and 1,800 meters above sea level or in the central part of the National Park. The majority of which has been altered by hill tribes, so the existing forests have been restored and new forests established. There are remnants of the original rainforest.

          The general condition of the hill evergreen forest in the Doi Inthanon area varies according to the restoration system and method used. Pure hill evergreen forest, mixed formations, coniferous forest (pine forest), and original evergreen forests are the most common types of forests found. Several notable plant species were discovered, including Benguet pine, Anneslea fragrans Wall, Helicia nilagirica, Castanopsis diversifolia, Castanopsis tribuloides, Quercus aliena Blume, Quercus kingiana Craib, Quercus semiserrata, Indochinese Tanoak, Schima wallichii, Michelia champaca, Betula alnoides, Diospyros glandulosa Lace, and Rhododendron surasianum.

           The upper hill evergreen forest  is located in an area with an elevation of at least 1,800 meters. There are three types of temperate rain forests: rainforests, temperate rain forests, and temperate swamp forests. They are alldense forests with tall trees. Additionally, numerous locations may resemble primary forest because the ground vegetation is sparse, and the trees branches, tops, and trunks protrude into the forest. There will be mosses, orchids, ferns, Rhododendron arboreum Smith, and Chaetocarpus castanocarpus, which might cover the plants of the evergreen or humid forest, such as Castanopsis purpurea, Quercus semiserrata, Michelia rajaniana Craib, Maerua siamensis, Wild Himalayan Cherry, Litsea monopetala, and many more. In addition, there are also shrubs and perch plants such as Westland’s Rhododendron, White Rose, Mallotus philippensis, Symingtonia populnea, and Sapria himalayana.

             There are numerous grasses in and around the swamp forest, including Hypericum hookerianum Wight, Persicaria chinensis, Garden Balsam, Hydrocotyle siamica, Heracleum siamicum Craib, Codiaeum variegatum, Polygala arillata, Dipterocarpus tuberculatus Roxb, and Lycopodium cernuum There is a Rhododendron simsii at the edge of the swamp forest, a species found only on the summit of Doi Inthanon.

            This National Park's wildlife population has declined significantly in recent years as they were hunted by the various hill tribes for food and safety. This resulted in the extinction of several large animals in this forest, and the majority of the remaining animals are small, such as the Squirrel, Common Treeshrew, Tamiops mcclellandii, Lesser Bamboo Rat, Asiatic Brush–Tailed Porcupine, Common Palm Civet, Large-Spotted Civet, Bronzed Drongo, Sooty-Headed Bulbul, Paddyfield Pipit, Falco Peregrinus, Silver Pheasant, Rufous-Necked Hornbill, Rosy Minivet, Calotes mystaceus, Leiolopisma melanostictum, Tokay Gecko, Red-Necked Keelback, Aquatic Frog, Rana limnocharis, Asian Toads, Indochinese Dwarf Toad, and Dwarf Bushfrog, Doi Inthanon National Park also is a habitat for rare wildlife, including Dianella ensifolia, Himalayan Newt , Siamese Large-Headed Terrapin, Bar-Throated Minla, White-Browed Shotwing, Ashy-Throated Warbler, and Green-Tailed Sunbird.
