The Pometia pinnata is a tropical hardwood tree species that is widespread in the Pacific and Southeast Asian regions.[2] The tree species has many common names, including Matoa, Taun tree, Island lychee, Tava, and Pacific lychee.[3] The species comes from the Sapindaceae family and comes from the clades of Tracheophytes, Angiosperms, and the order Sapindales.[3]
Characteristics
[edit]The hardwood tree species occurs and grows in a wide variety of habitats and vegetation. The size of the tree varies, ranging from 12–20 metres (39–66 ft) tall with a 10–20 m (33–66 ft) wide canopy.[4] The tree grows an average of 1–2 m (3.3–6.6 ft) per year.[3] Its canopy is made up of lush, evergreen leaves that create wide coverage.[2]
Pometia pinnata is a fruiting and flowering species, and it produces white to green-yellow flowers.[2] The male and female flowers are similar in size and color, so it is hard to differentiate between them.[3] They grow in long stalks, 2–2.5 millimetres (0.08–0.10 in) in length, and produce flowers that can potentially fruit.[2] The fruiting process takes 2–3 months and the fruit is green-yellow when developing. They are under developed when the fruit is tough and fleshy. When it is ripe and edible, the fruit will turn red-black in color, and become softer in texture.[4] The species is also self-pruning, and can reproduce rapidly even in tropical forests.[4]
Habitat and range
[edit]Pometia pinnata is a widespread type of timber tree species. The species originated from Sri Lanka and the Andaman Islands through Southeast Asia.[4] The pinnata species also inhabits New Guinea and other Pacific islands.[3] It grows naturally in warm to hot, humid subtropical and tropical zones, with a typical elevation of 0–500 m (0–1,640 ft). The trees need an annual rainfall of 1,500–5,000 mm (59–197 in).[4] The species has a natural, native range in the Asian-Pacific region of the globe. The Tava species is native throughout the island of Borneo.[4] The plant species has a range of distribution that keeps growing, but not invasive. It is modernly distributed to New Caledonia, eastern Polynesia, and the North Pacific islands, like Hawai'i.[4]
Possible benefits and threats
[edit]Residents of the Pacific islands benefit from the fruiting tree. They are able to collect the freshly produced fruit from the trees and collect timber for logging and trades.[4] Pometia pinnata has a very low invasive potential, and the species spreads and distributes naturally throughout the Pacific Islands.[4] The only other possible threat to the species is a risk of defoliation in specific regions of the South Pacific.[4] Meaning that its leaves could suffer from a shot-holed appearance. It does not necessarily kill the trees, but does occur when the tree is becoming fully mature.
Mitigation and control
[edit]The control and mitigation of the species is fairly easy and straightforward. Papua New Guinea's constitution protects all aspects of wildlife and nature, including Pometia pinnata.[3] In other locations of this species, the trees are protected as well. The species is a major resource to its countries of origin and will be protected as an asset.[3]
