Editing Karst (section)

=== Kegelkarst, salt karst, and karst forests ===
Kegelkarst is a type of tropical karst terrain with numerous cone-like hills, formed by cockpits, [[mogote]]s, and [[polje]]s and without strong fluvial erosion processes. This terrain is found in Cuba, Jamaica, Indonesia, Malaysia, the Philippines, Puerto Rico, southern China, Myanmar, Thailand, Laos and Vietnam.<ref>Whittow, John (1984).

Salt karst (or 'halite karst') is developed in areas where [[salt]] is undergoing solution underground. It can lead to surface depressions and collapses which present a geo-hazard.<ref>{{cite web |last1=Cooper |first1=Anthony H. |title=Halite karst geohazards (natural and man-made) in the United Kingdom |url=https://nora.nerc.ac.uk/id/eprint/6218/2/Halite_karst_geohazards_Cooper_Env_Geol_vol42_505-512.pdf |publisher=BGS/NERC |access-date=9 October 2022}}</ref>

Karst areas tend to have unique types of forests. The karst terrain is difficult for humans to traverse, so that their ecosystems are often relatively undisturbed. The soil tends to have a high pH, which encourages growth of unusual species of orchids, palms, mangroves, and other plants.<ref>{{cite web |last1=Evans |first1=Monica |title=Karst forests: the labyrinthian wildlands of green and bedrock |url=https://news.globallandscapesforum.org/43769/karst-forests-the-labyrinthian-wildlands-of-green-and-bedrock/ |website=Global Landscapes Forum |date=2020-04-15}}</ref>
