[MAIPC] Invasive plants and climate change

Thu Jan 31 10:58:19 PST 2019

Miscanthus is a huge problem in the rare serpentine area of Lake Roland in Baltimore County. It has spread into the park and all up and down Falls Road from one business that planted it out front.

I have started seeing this MUCH more in natural areas just in the past 3-5yrs than I had ever noticed before.   It is spreading even into maintained lawn grasses.  (I have a small patch In the corner of my yard that has come around the corner of my fence from the neighbors landscaped flowerbed ☹…trying to now come up with a good control for it without killing the rest of my lawn grass, or having to dig it all up by hand and have holes in the yard.

I am seeing it a lot on open, abundantly sunny wood edges, mowed paths, and even now into the shady understory of mature forested areas.

My first introduction to the idea of invasive exotic plants was fighting oriental bittersweet in Connecticut, 1978-81. At the time, I didn’t know of anyone else fighting the problem, but I called it a “take-over-the-world” plant & honed my recognition of it in its earliest, most easily pullable stages.

I know there’s been talk of southern magnolia and other species that are native to just south of here starting to naturalize in our area, but I’m more interested exotic invasives.
