Dear Marc,

Has some questions about your mustard project:

1.) How many square feet or acres are you working on? 

400 acres

 2.) Do you physically remove the plants from the site or use them as mulch
to kill other plants nearby? 

spot spray or remove and bag  

3.) Ever try knocking down the plants, then use the mustard stems as mulch? 

no

 4.) After the mustard is managed, what natives are planted/sown to take up
that space? 

They come back in within 5 years very well on their own.  (The other major
invasives are also removed)

5.) Ever use native grass mulch? 

No 

6.) Ever tested the soil where the mustards are growing, to see if nutrient
deficiencies are helping the mustards grow there instead of the local
natives?  In California, Italian thistle and medusa head grasses thrive in
soils where the potassium has been grazed out below the threshold needed for
native seedling survival, for example. 

It is found in all habitats

> This year we have removed 100% of the adult garlic mustard from Montpelier
> Mansion Nature Trail, Little Paint Branch Park, Cherry Hill Park, and
> Magruder Woods in Prince George's County, and Swann Park in Charles
> County.
> We searched the entire 400 acres of these 5 parks and, hopefully, did not
> miss any. Remember for next year: do not miss a single adult because of

> seeds. The spray treatments before seeds started forming were for small
> mono-cultural patches.
>
> For Magruder Woods we completed the routine Trumbule Trail side and we
> began
> the Western side in preparation for new leadership for that side of the
> park. Montpelier took 1 person during one day. The traditional Trumbule
> Trail side of Magruder took 27 volunteers a total of 32 person hours.
> Swann
> Park took 8 volunteers a total of 58 person hours. Cherry Hill took 5
> volunteers 29 person hours and Little Paint Branch Park took 33 volunteers
> 84 person hours.
