Myoporum (Scrophulariaceae): Introduction, naturalization, and invasion of an enigmatic tree genus in South Africa

Popis výsledku v původním jazyce

Myoporum is a genus of trees and shrubs native to the Northern Hemisphere that has been introduced to many parts of the world, mainly for ornamental purposes. We assessed the introduction history, distribution, and extent of naturalization/invasion for Myoporum species in South Africa. Information was collated to determine key events associated with the introduction, establishment, and naturalization of Myoporum in South Africa. Data were collated to determine the current distribution of the genus in South Africa. Twenty sites in the Western Cape were sampled to determine correlates of naturalization . Myoporum was first recorded in South Africa in 1934. Three species were con firmed to be present in South Africa: M. insulare , M. laetum and M. montanum (37 %, 25 % and 24 % of all iNaturalist records respectively). Most records are from the Western Cape (91 %) and small parts of the Eastern Cape, isolated populations occur in Gauteng and the Northern Cape. We could not con firm the presence M. petiolatum , M. tenuifolium or M. tetrandrum . Field surveys revealed widespread naturalization of M. insulare (46 % of all Research Grade observations in iNaturalist), this species was categorized code D1 in the introduction-naturalization-invasion continuum. Myoporum laetum (C3) and M. montanum (C2) are also widely naturalized but over smaller areas. Naturalized populations comprised predominantly juvenile M. insulare plants occurring in highly disturbed (transformed) habitats. Formal risk analyses for all Myoporum species in South Africa are needed as the basis for re-evaluation of their status in national legislation.
