Invasive Species Impact and Management
Trade-offs at applying tree nucleation to restore degraded high Andean forests in ColombiaBackgroundThis article recognizes applied nucleation as a forest restoration strategy in many low to mid altitude forests and aims to compare applied nucleation to passive regeneration at high altitude forests. Applied nucleation is successful at accelerating the speed of forest regeneration, improving soil conditions, and shading out invasive species in many low-mid altitude forests of the neotropics. There are gaps in the literature about the performance of applied nucleation in other tropical regions as well as high attitude tropical forests. Available with subscription or purchase |
Distribution and genetic diversity of five invasive pests of Eucalyptus in sub-Saharan AfricaBACKGROUNDPlantation forestry in Sub- Saharan Africa has been characterized by an introduction of several Eucalyptus species because of their socio- economic benefits. However, these Eucalyptus trees have been affected by non- native foliage feeding insect pests, which have been accidentally introduced, resulting in stunted growth and in some cases mortality. The rate of introduction of non-native eucalypt-feeding insects globally has increased nearly five-fold between the 1980s and 2010s. Open access copy available |
Floristic composition, structure and natural regeneration in a moist semideciduous forest following anthropogenic disturbances and plant invasionBackgroundThis research examined the floristic composition, struture and natural regeneration in three different forests: undisturbed (UF), disturbed-invaded (DIF) and disturbed (DF) within a forest reserve in Ghana.

Effects of Invasive Alien Plants on Fire RegimesBackgroundThis article considers how invasive plant species affect native ecosystems by altering fuel properties, fire behavior and fire regime characteristics. These may impact the ability of a site to restore to its previous state. Open access copy available |
Multiple-Purposes Reforestation on Degraded Lands in Longyang, ChinBackgroundThe following is a project design document submitted to the UNFCCC in 2008 for a project to restore and preserve degraded forests in Longyang, Yunnan, P.R. China. The project will be headed by the Longyang Forestry Farm in cooperation with local farmers. Open access copy available |
Responses of Transplanted Native Tree Species to Invasive Alien Grass Removals in an Abandoned Cattle Pasture in the Lacandon Region, MexicobackgroundThis study measures the response of 16 native tree species to manual invasive grass removal treatments, for cost-effective regeneration of tropical forest on abandoned cattle pasture in the Lacandon region of Chiapas, southeast Mexico.

Floristic Composition, Structure and Natural Regeneration in a Moist Semi-Deciduous Forest following Anthropogenic Disturbances and Plant InvasionbackgroundThis study examines the floristic composition, structure and natural regeneration in three forest types: disturbed forest (DF), undisturbed forest (UF), and disturbed-invaded forest (DIF) in Tinte Bepo forest reserve in Ghana. In addition, this study also considers how anthropogenic disturbances and plant invasion affect plant species composition. Open access copy available |
Responses of Tree Seedlings to the Removal of Chromolaena odorata Linn. in a Degraded Forest in GhanabackgroundThis study assesses the effects of Chromolaena odorata, a dense grass removal on native trees seedlings in a degraded dry semi-deciduous forest in Ghana. Research Goals & MethodsChromolaena odorata was removed from 50% of the plots and the other half left intact. Seedling height, the number of leaves per seedling, and seedling mortality were investigated in both released and unreleased plots immediately after the release treatment in June 1998 and again 3 months later September 1998.

Restoration of a Coastal Swamp Forest in Southeast BrazilbackgroundThis study evaluates the potential for nine native tree and shrub species for use in the revegetation of degraded swamps in Rio de Janeiro, Brazil. Research Goals & MethodsInvasive grasses and other vegetation, including the exotic tree Casuarina equisetifolia were removed from the site. Available with subscription or purchase |
