Ugh! Alnus glutinosa is rampant at Quechee Gorge in Vermont. I've seen it along the Connecticut River shore down towards Claremont, NH, too. How appalling to hear that it is being planted elswhere! I won't be there tomorrow, but hope you have a great meeting. Alice --- Matt wrote: Is anyone familiar with Alnus glutinosa (European alder)? Come to find out, this plant is getting planted more and more on wetland mitigation sites in Maine. The plants are commonly mis-labeled as Alnus rugosa. Whether it's intentional or not, I don't know. There is documented evidence that this species can become aggressive and escape cultivation. However, I'm not aware of any instances of naturalization in Maine yet. A notched/rounded leaf apex and resinous texture to the leaves help to distinguish it from A. incana. Those of us involved in wetland mitigation planning and monitoring need to be especially aware of this species getting thrown into the mix and to also keep our eyes open for naturalized populations. The DEP and Army Corps are aware of this and have, in some instances, required the removal of this species from mitigation sites. I've since learned that you can't believe any label on nursery stock or seed mixtures. This could be a good topic for discussion tomorrow at JBS. See folks on Saturday. -Matt --- end of quote ---
