CABI has led an international team of scientists who strongly suggest that the global trade of forest tree seeds is not as safe as previously believed, with insect pests and fungal pathogens posing a great risk to trees and forest ecosystems worldwide.
Non-native insect pests and fungal pathogens present one of the major threats to trees and forest ecosystems globally, with the potential to cause significant ecological changes and economic losses.
Whilst prevention is better than a cure, it is not always possible to stop every invasive species from entering an area. In these instances, early detection and rapid response are crucial, as management is much easier while the population of an invasive species remains small. Detection of small populations, however, can be incredibly difficult. With the spread of invasive species becoming an ever increasing problem around the world, it could pay to think outside the box when trying to manage them – could animals help with the fight against invasive species? Researchers and conservationists seem to think so. Continue reading →
Following on from an IUCN call for greater action on addressing invasive species in order to protect biodiversity – the Honolulu challenge, presented at the 2016 IUCN World Conservation Congress – the latest IUCN brief presses home the links between invasive species and climate change.
Climate change facilitates the spread and establishment of many alien species and creates new opportunities for them to become invasive. Climate change also reduces the resilience of habitats to biological invasions However, the inverse is also true: invasive species reduce the resilience of natural habitats, agricultural systems and urban areas to climate change.
