Repelling the Invaders!

The article looks at ways of working towards a sustainable legacy of effective invasive-species management in the Thames Gateway area in England. The best-practice approach to sustainable management that is being promoted in the region recommends risk assessment of the species found to assess what current or potential impact they may have and cost/benefit analysis to assist whether the benefits gained are sufficient to justify the cost of controlling the species. Among the measures that can be used to prevent invasion are installation of checks and barriers, habitat management and regular site monitoring.
