According to this story in the Philadelphia Inquirer, homeowners in Pennsylvania can now get their very own environmental audits - for free! Audubon Pennsylvania has partnered with Friends of the Wissahickon to sponsor the program, which involves a visit to the homeowner's property from the Audubon at Home program. Once there, an Audubon staffer will survey the property and point out all of the invasive plant foibles. Participants also get lots of advice on native plant alternatives and how to make homes more inviting to local wildlife.
It turns out there are actually lots of options, at least in the Pennsylvania area, if you are looking to getting your own home an environmental audit, though a fee is typically required. If you live in the Northeastern USA and want to check out some alternatives to replace your invasive plants, you are also welcome to play with this tool my lab developed using the nursery catalog of the New England Wildflower Society.
