Mechanism
A number of exotic plants have invaded the region and marsh systems are especially susceptible. Chinese tallow is an example of an invasive species that can colonize wet and dry areas. Marshes are especially problematic during droughty conditions when germination can occur more rapidly.
Mechanism
The driver for restoration is control of invasives. Although an option, mechanical removal of the trees is difficult because they readily regrow from roots and seeds. Several chemicals methods are available including glyphosate for cut-stump treatments, triclopyr for cut-stump and foliar treatments, imazamox for broad spectrum application, and imazapyr as a foliar spray. Many aquatic herbicides have water use restrictions and can potentially kill hardwoods, so labels and restrictions should be read carefully prior to application.
