Woody plant species have been deliberately introduced into many arid and semi-arid regions across the world as they can help combat desertification and provide resources – like fuelwood – to the rural poor. But some of these alien trees and shrubs have become invasive, having devastating effects on other species as well as people.
This is big problem in the mainly arid Baringo County, in Kenya’s Rift valley as well as other counties north, east and south of the country.
This week many people across the world stopped and stared as extreme headlines announced that one eighth of the world’s species – more than a million – are threatened with extinction.
According to the UN report from the Intergovernmental Science-Policy Platform for Biodiversity and Ecosystem Services (IPBES) which brought this situation to public attention, this startling number is a consequence of five direct causes: changes in land and sea use; direct exploitation of organisms; climate change; pollution; and invasion of alien species.
It’s the last, invasive species, that threatens Australian animals and plants more than any other single factor. Continue reading →
Invasive crazy ants threaten Christmas Island Red Crab populations, but a certain species of wasp might be able to help.
Christmas Island, a remote Australian territory in the Indian Ocean, is known for an abundance of Red Crabs, a species once recorded in numbers nearing 44 million. The Red Crab has captured the hearts of naturalists and nature novices alike, due to the beauty and magnificence of their yearly mass migration from land to sea to lay their eggs in the ocean. However, in recent years, they have suffered a tremendous decline of roughly 40 million, according to recent population surveys. The cause? Invasive crazy ants, which are believed to have been introduced by a ship sometime during the early 20th century.
Plantix is a diagnostic app that uses image recognition software and AI. It is being used to halt the advance of the fall armyworm pest.
An app that uses artificial intelligence to identify plant disease is being deployed in India as an early-warning system to stop the advance of a crop-destroying caterpillar that is having a devastating impact on maize crops in Africa.
CABI has published one of the most complete and current datasets on Invasive Alien Plants (IAP) in East and Southern Africa. This extraordinary dataset is already being translated into new research findings and conservation action on the ground.
