|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  and is known to drive critical forest
processes including fires . Besides C. odorata another
invasive species that has come up strongly is Broussonetia
papyrifera,  a medium-size tree of the Moraceae family
widely grown for paper production and native to Japan and
Taiwan . 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 . 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 .
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|
