The record of eradicating invasive plants, whether on islands or continents, consists of few clear victories, some stalemates, and many defeats. Instructive, if hard-won, lessons have nevertheless been learned. (1) The ideal eradication campaign would see all individuals of a potentially-invasive species destroyed immediately upon their arrival. Few immigrants meet this fate; more usually there...

Submerged aquatic invasive plant species are increasingly being recognised as a major threat to South African water ways. Pet stores, aquarists and the internet-mediated trade were investigated as pathways for submerged invasive macrophyte introductions into South Africa. Online and manually distributed surveys were used to determine the extent of movement of invasive as well as indigenous subm...

INTRODUCTION: The United States Army Corp of Engineers (USACE) Ecosystem Management and Restoration Research Program (EMRRP) is supporting a nationwide effort to address the impact of invasive woody plant species on ecosystem restoration, and more specifically, to determine mechanisms to address the most regionally prevalent invasive species impacting restoration activities. The research effort...

Invasive plants are common and may provide resources through litter for container mosquito larvae. Invasive plant reproductive parts can make up a substantial part of litter but have mostly been ignored as a resource for mosquito larvae. We hypothesized that the reproductive fruits of the invasive eastern red cedar, Juniperus virginiana, provide high quality resources for the invasive, containe...

BACKGROUND AND AIMS The successful spread of invasive plants in new environments is often linked to multiple introductions and a diverse gene pool that facilitates local adaptation to variable environmental conditions. For clonal plants, however, phenotypic plasticity may be equally important. Here the primary adaptive strategy in three non-native, clonally reproducing macrophytes (Egeria densa...

Prioritizing areas for management of non-native invasive plants is critical, as invasive plants can negatively impact plant community structure. Extensive and multi-jurisdictional inventories are essential to prioritize actions aimed at mitigating the impact of invasions and changes in disturbance regimes. However, previous work devoted little effort to devising sampling methods sufficient to a...

BACKGROUND Invasive alien plant species (IAPs) are plants that have migrated from one geographical region to non-native region either intentional or unintentional. The general view of IAPs in environment is regarded as destructive to the ecosystem and they pose threat to native vegetation and species. However, some of these IAPS are utilized by local inhabitants as a substitute for scarce indig...
