Invasive Plants are Destroying Your Woodland!
Loss of future timber harvest revenue
USFS and Indiana DNR State Property inventories show that our woodlands gain an average of 179 bd ft/acre volume growth annually. A study by the Dept. of Plant Biology at Ohio University found that in woodlands with an understory dominated by Bush Honeysuckle, there was a reduction of hardwood tree annual volume growth of up to 53%. This loss is due primarily to elements produced by the shrubs which stunt the growth of adjacent plants. Competition for sunlight, moisture and nutrients also contribute to the loss. Simple math shows the drastic financial impact this can have.
179 bd ft/ac X .53 = 94.87 bd ft/ac loss
At an average price of $0.35/bd ft this equates to a loss of $33.20 per ac, per year. In a 40 acre tract, this means an annual loss of $1,328.18 future timber harvest revenue per year. If a managed woods has a harvest on average, once every 15 years, this equals to a potential loss of up to $19,923.00 at each harvest!
Loss of Native Plant Diversity
The same compounds that stunts hardwood growth also stunt and prevent the growth of native herbaceous plants and grasses.
Decreased wildlife Use
A loss of plant diversity in invasive plant-dominated woodlands leads to less wildlife food, nesting sites and escape cover for many wildlife species.
Increased Tick Populations
According to the Lyme Disease Research Lab at Maine Medical Center Research Institute, tick populations are typically twice as high in invasive plant dominated areas.
Loss of Recreational Area
Invasive plant dominated areas can be almost impossible to walk through. Many people enjoy hiking and riding ATVs through their woodlands, which can become very difficult in these areas!
