FAIRCHILD TROPICAL GARDEN
Invasive species are among the
biggest threats to biological diversity. They also represent a threat
to health and can pose significant environmental costs. The public and
scientific response to this growing problem varies between hysteria and
complacency. This talk will provide an overview of the problem, looking
at the various types of invasive organisms (viruses, algae through to
parrots and snakes), their impacts and some of the possible responses.
So far the isolated oceanic islands have suffered the greatest impact
from invasives; however it is clear that this impact is expanding to
encompass continental ecosystems and urban areas.
