Invasive Plant Management
What is an Invasive Species?
According to Executive Order 13112 an invasive species is defined as "an alien species whose introduction does or is likely to cause economic or environmental harm or harm to human health."
Are they a problem at Duke Farms?
The extent of invasive plant species infestation at Duke Farms is enormous. In 2007, a total of 81 non-native plant species were mapped on the property with an estimated infestation of over 2,600 acres.
How does Duke Farms control their invasive plant species?
The control of invasive plant species at Duke Farms is a challenging task that is warranted by its conservation targets. The enormity of this infestation requires a strategic vision coupled with a continuing allocation of resources.
A “brute force” (i.e., non-strategic) approach that seeks direct control of all invasive species is financially untenable.
Instead, a more strategic approach is recommended to address the invasive species problem both directly through control measures and indirectly through broad habitat management techniques that reduce invasive plant species cover and/or increase native plant species cover and resistance to future infestation.
