[MAIPC] [Maipc-brd] Garlic Mustard scarce this season, in 2018?

[Foster, Donna M -FS]

In regards to Garlic Mustard, attached is a garlic mustard update by Bernd Blossey, Cornell University.

I’m not sure I agree with his management recommendation not to remove it (I believe if you have volunteers and can pull it, PULL IT!).

The correlation between invasive earthworms is quite interesting. Here in our FS Office we have forest health staff exploring the relationship of exotic earthworms to many different impacts on forest health and regeneration and findings seem to substantiate this also.

At my home here in Morgantown, WV, the populations is as strong as ever. Also, I spent 2 weeks in NE PA the last two weeks in April and saw the population expanding again this year. Interestingly, both woodlands have very large deer populations…

I hope this helps.

Hi Carol,
One of our board members noted that he has not seen much of a difference and he's out in the field quite a bit around DC and MD.
On the other hand, I don't get out in the field much at all any more (sadly). But what little I have seen from hiking around on weekends on my own does seem (anecdotally) to be less. But I'm not sure I can venture as far as to say I think it may be the frigid winter we've had. We've had worse winters when it didn't seem to have much of any effect on the Garlic Mustard. In my case, I'd like to think the areas I've visited are getting lots of great staff and volunteer control efforts that are staring to bear some success, since I tend to visit a lot of the same areas year after year and see diminished return with each year. =)

To MAIPC,, Have you noticed that Garlic Mustard seems scarce this season? Everywhere?



Consider the possibility that Garlic Mustard is scarce in 2018, all over. In areas previously cleared or not. I’m thinking the frigid winter destroyed most of the 1styear or overwintering Garlic Mustard leaves, except on plants located in very protected spots. Here in Baltimore City on May 3, 2018, some few scattered 2ndyear plants are in flower. I am pulling the occasional plant that stands <15” tall. Oddly, I also see some nearby patches looking like 1styear rosettes, like a ground cover. Too soon for that. Maybe they are the 2ndyear plants/roots, sending new stalks up from scratch.



I invite your reaction to this novel observation -- and interpretation. Thank you for any wisdom.
