Abstract: Of the important factors responsible for biodiversity loss in Ghanaian forests, species invasion is the least cited and investigated. This is despite the fact that the invasion of Chromolaena odorata for instance has been recorded in Ghana since 1972 [1] and is known to drive critical forest processes including fires [2]. Besides C. odorata another invasive species that has come up strongly is Broussonetia papyrifera, [3] a medium-size tree of the Moraceae family widely grown for paper production and native to Japan and Taiwan [4]. The species was introduced to Ghana by the Forestry Research Institute of Ghana (FoRIG) in 1969 to form part of an experimental programme to identify species for the local production of industrial cellulose [5]. It was planted in three forest reserves in the semideciduous forest zone on a trial basis, namely, Afram Headwaters, Bia-Tano, and Pra-Anum. From these three sites it has spread and invaded large canopy gaps and degraded farmlands in many parts of the forest zone. Its invasion has been most remarkable in the north west subtype of the moist semideciduous forest presumably due to its highly noticeable forest fragmentation. Viable populations of the species are found as far north as Dormaa Ahenkro near the Ghana-Cote d’Ivoire border. However, beyond the semideciduous forest zone reports of its invasion are not available possibly due to lack of recent inventories. The invasion of B. papyrifera in Ghana has been internationally acknowledged for more than a decade [6]. Elsewhere including 11 states in the United States of America and over a dozen countries, B. papyrifera is reported as an invasive species [7, 8]. There is a need to understand the extent to which it is a threat to natural ecosystems and how it can be controlled if necessary. However, no enough scientific information is available on the species in Ghana to make this achievable. At present what is known is that B. papyrifera normally occurs
