C·I·B researcher analyse pathways of biological invasions

Invasions of alien species begin with the human-assisted movement of living individuals or propagules across biogeo­graphic barriers. As a result, the contributions of specific path­ways to introduction and subsequent invasion—and the changes in the importance of pathways over time—are receiving increasing attention from scientists and poli­cymakers.

No time to waste in dealing with a biodiversity-debt crisis

Recently there have been a series of debt crises in economies around the world, from Greece to Argentina to the U.S.A.  Unfortunately we also have a global biodiversity-debt crisis. These debt crises share one important feature in common—managers need to respond to the emergency.

The study found that most households use both native trees and/or mesquite for fuelwood. However, the majority of stakeholders across ten communities in the Northern Cape still use native trees more than mesquite. (Photo credit: Ross Shackleton)

The negative impacts of Prosopis invasions outweigh its benefits

Many invasive species provide both benefits and costs to society and the environment. These benefits include aesthetic values, but also provide resources such as timber, fuelwood, fodder and food.

Measuring ecological impacts of alien species

Alien species cause a number of impacts in the ecosystems they live in, ranging from hardly detectable to dramatic change. Measuring such impacts is not always straightforward. Furthermore, a wide range of methods and variables has been used to describe these impacts, making comparison between species and habitats difficult.

Getting the measure of tree invasions

“If you can't measure it, you can't manage it” is, as with all such well-worn phrases, only partly true. But to adapt another such maxim, while we might be able to make progress without measurement, we do need proof to satisfy everyone else.
