NY Invasive Species Research Institute appoints Carrie
Brown-Lima as Coordinator
Thousands of introduced species have taken up residence in the
US, posing serious threats to agriculture, human health, and the integrity of
our lands and waters.
As a major port of entry, New York State, with its vast natural
and agricultural resources, is vulnerable to damage from many of these invasive
NYISRI serves the scientific research community, natural resource and land managers, and state offices and sponsored organizations by promoting information-sharing and developing recommendations and implementation protocols for research, funding, and management, all in an effort to improve the scientific basis of invasive species management.
Spotlight on Research
What is the importance of deer and earthworms in facilitating
non-native plant invasions? How can we manage these multiple
These important questions motivate the research of Annise
Dobson, a graduate student of Dr. Bernd Blossey, Associate
Professor of Natural Resources at Cornell University. Evidence
from work in the Finger Lakes Region and in the Hudson River
suggests that native white-tailed deer are the overwhelming
stressor of forest ecosystems in the region.
But advancing Asian earthworm in the genus
called crazy worms due their rapid wiggling behavior) have
devastating effects on forest floor communities including
invertebrates and salamanders.
Both advancing earthworms and high deer populations favor
non-native plant invasions.
Targeting invasive plants for removal (such as garlic
mustard) will have little conservation benefits without also
addressing the underlying deer and earthworm problems.
