Understanding and Managing Disease in Forest Ecosystems
|
|
|
The issueExotic pathogens, plants, and insects are non-native or alien species that have been introduced into new ecosystems outside of their native range. They are invasive if they become established and spread. Native species can also be invasive. Both exotic and native invasives can seriously damage our urban and rural forests, reducing their ecological, economic, and social value. Managing invasive species and their impacts involves integration of several elements, including prediction and prevention, detection and monitoring, and management and restoration. |

What are doing about it?
We
are conducting research to provide science-based information on
basic biology of high priority invasive species and some of the
tree diseases they
cause.
We
are designing models and assessing of impacts and risks
to predict and prevent
the introduction and spread of high priority invasive forest pests.
We
are conducting surveys to
detect and monitor
invasive species.
We
are developing methods and tools to
manage and restore
our forests and plantations that have been impacted by invasive
species.
