Seasonal (mixed) tropical forests can be found in many parts of the tropical zone, with examples found in:

• In the Asia-Pacific region: seasonal forests predominate across large areas of the Eastern Java, Wallacea, Indian subcontinent and Indochina
• Eastern Java monsoon forests
• Wallacea Forest
• Brahmaputra Valley semi-evergreen forests
• Mondulkiri Province, Cambodia
• Cat Tien National Park, Vietnam
• Khao Yai National Park and Huai Kha Khaeng Wildlife Sanctuary, Thailand
• Northern Australia: Cape York Peninsula (Queensland), Arnhem Land (Northern Territory), The Kimberly (Western Australia){{Citation | author1=Beard, J.S. | author2= Keneally, K.F. | title= 'Rainforests of Western Australia'.

The climate of seasonal forests is typically controlled by a system called the Intertropical Convergence Zone (ITCZ), located near the equator and created by the convergence of the trade winds from the Northern and Southern Hemispheres. The position of these bands vary seasonally, moving north in the northern summer and south in the northern winter, and ultimately controlling the wet and dry seasons in the tropics.[http://www.srh.noaa.gov/jetstream/tropics/itcz.htm NWS JetStream – Inter-Tropical Convergence Zone]. Srh.noaa.gov (5 January 2010). Retrieved on 28 March 2013.

These regions appear to have experienced strong warming, at a mean rate of 0.26 degrees Celsius per decade, which coincides with a global rise in temperature resulting from the anthropocentric inputs of greenhouse gases into the atmosphere. Studies have also found that precipitation has declined and tropical Asia has experienced an increase in dry season intensity whereas Amazonian has no significant pattern change in precipitation or dry season. Additionally, El Niño-Southern Oscillation (ENSO) events drive the inter-annual climatic variability in temperature and precipitation and result in drought and increased intensity of the dry season. As anthropogenic warming increases the intensity and frequency of ENSO will increase, rendering tropical rainforest regions susceptible to stress and increased mortality of trees and other plants.

As with tropical rainforests there are different canopy layers, but these may be less pronounced in mixed forests, which are often characterised by numerous lianas due to their growth advantage during the dry season.Ya-Jun Chen, Kun-Fang Cao, Stefan A. Schnitzer, Ze-Xin Fan, Jiao-Lin Zhang, Frans Bongers (2015) Water-use advantage of lianas over trees in seasonal tropical forests. New Phytologist, 205[1]: 128–136 The colloquial term jungle, derived from the Sanskrit word for "forest", has no specific ecological meaning but originally referred to this type of primary and especially secondary forest in the Indian subcontinent. Determining which strands of mixed forest are primary and secondary can also be problematic, since the species mixture is influenced by factors such as soil depth and climate, as well as human interference.

The fauna and flora of seasonal tropical mixed forest are usually distinctive. Examples of the biodiversity and habitat type are often well described for National Parks in:

• Africa represented by:
• the northern part of Korup National Park in Cameroon (central region)

• the Upper Guinean forests (West Africa)
• Asia represented by Cat Tien National Park and Huai Kha Khaeng in the (Indochina region)
• Pacific region: including the Queensland forest reserves
• Central American wildlife is well represented in:
• Costa Rica e.g. Corcovado National Park
• the Soberanía National Park in Panama.
• South American flora listed and represented in Rio Doce State Park
