It was a little while ago when, inspired by a talk by one of Vermont’s county foresters, we started this series of blog posts about how ordinary landowners can care for their sugar woods in a changing climate.
Since then, we have covered mapping invasive species and cultivating an ideal suite of tree species. That leaves removing invasive species and protecting riparian buffers and other critter habitat. We’ll cover the former today, and the latter very soon.
You may recall that among the peskiest invasive species in sugar country are buckthorn, honeysuckle, and barberry, all three of which we found in our own woods over the summer. According to the Nature Conservancy, the best time to remove at least two of the three is fall, so we stayed our hand until now.
Thankfully, this delay gave us time to connect with Emily Seifert, a naturalist who spent several years as a Stewardship Manager for the Nature Conservancy, managing nature preserves by, among other things, monitoring and removing invasive species from the land. Emily knows a lot about the woody plants that have invaded the forests of sugar country, how to identify them, and how to safely remove them, so one cool morning, we set out on the homestead with our invasive map to have a look.
We are proud to report that Emily confirmed that we had correctly identified our invasives in all instances! Huzzah! We have not lead you astray! While you are likely to find, like we did, that honeysuckle and barberry are easy to identify, buckthorn is harder, and we are more than a little impressed with ourselves that we got it right. As we’ve discussed, mature plants will have fairly recognizable blue berries in late summer and early fall, but at other times of the year, and for immature plants, you have to really concentrate on leaf shape, color, and position. Emily recognized even our immature buckthorn immediately as such, of course, but passed along these hints for beginners: the underside of buckthorn bark is bright orange and even the immature plants may sport a thorn or two.
