''Prosopis pallida'' is a species of mesquite tree. It has the common names kiawe, huarango and American carob, as well as "bayahonda" (a generic term for ''Prosopis'') and "algarrobo blanco" (usually used for ''Prosopis alba''). It is a thorny legume, native to Colombia, Ecuador and Peru, particularly drier areas near the coast. While threatened in its native habitat, it is considered an invasive species in many other places. The kiawe is a spreading bush or moderately sized tree, bearing spines, spikes of greenish-yellow flowers, and long pods filled with small brown seeds. It is a successful invasive species due to its ability to reproduce in two ways: production of large numbers of easily dispersed seeds, and suckering to create thick monotypic stands that shade out nearby competing plants. It survives well in dry environments due to a long taproot. It is so efficient at extracting moisture from soil that it can kill nearby plants by depriving them of water. It can be found in areas where other plants do not grow, such as sandy, dry, degraded slopes, salty soils, disturbed areas, and rocky cliffs. The tree grows quickly and can live for over a millennium. It makes a good shade tree, and its hard wood is a source of long-burning firewood and charcoal.〔 Kiawe pods can be used as livestock fodder, ground into flour, turned into molasses or used to make beer.〔 The light yellow flowers attract bees, which produce from them a sought-after white honey.〔Slow Food Foundation Ark of Taste.

Retrieved 5 October 2013.〕 Fallen Kiawe branches usually contain sharp spines that can puncture both feet and tires. At times the tree was used to replace forest and prevent erosion, and once it was established it generally dominated the habitat. It was introduced to Puerto Rico and Hawaii as well as New South Wales and Queensland in Australia and is now considered to be naturalized in those places. The first kiawe was planted in Hawaii in 1828; today it is a ubiquitous shade tree and invasive weed on the Hawaiian Islands, but provides firewood for heating and cooking. The clearing of kiawe (''huarango'') has been suggested as a major reason for the collapse of the Nazca culture in southern Peru at the beginning of the after an El Niño event led to flooding, erosion and desertification. Ecologists consider the huarango important to the ecosystem of the desert area west of the Andes in southern Peru, because of its ability to bind moisture and counter erosion. Despite prohibitions by regional authorities, poor villagers continue to harvest the trees to make charcoal. Efforts are under way to reforest the area with huarangos.〔Climate Stewards.
