[APWG] Garlic mustard removal--questions about project

[craig at astreet.com]

Dear Marc,
Has some questions about your mustard
project:
1.) How many square feet or acres are you working
on?
2.) Do you physically remove the plants from the site or use
them as mulch to kill other plants nearby?
3.) Ever try knocking
down the plants, then use the mustard stems as mulch?
4.) After the
mustard is managed, what natives are planted/sown to take up that
space?
5.) Ever use native grass mulch?
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.

> 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

> the

> 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.
