Pocket Prairie |
| This prairie was established in 1999 in the 4.5
acre agricultural field near Pleasant Valley Road. Its location
is shown on the vegetation map. It
is at the bottom of the ridge and receives drainage from a major
ravine at its east end. Because of this, it is considerably more
mesic than Toby's Prairie. However, it is not as level, rising considerably
towards its north side. Also, the southeast and southwest corners
rise sharply. The soil in these corners is quite sandy and favors
the growth of sand prairie species such as lupine. |
|
This field was treated with herbicide in 1998 when
the upper CRP field (Toby's Prairie) was treated, but it was not
planted until 1999. In 1999 it was treated three times with glyphosate
and burned in August 1999.
Planting. It was handplanted in November 1999
with 90 species of forbs and grasses (see photo below). All the
seeds were hand collected, either at Pleasant Valley or at nearby
sites. Because of the variety of habitats, different seed mixes
were used in different areas. The sandy areas received more dry-site
grasses such as little blue stem and side-oats grama, as well as
lupine. The mesic areas, and especially the areas receiving drainage
from the ravine, received plants thriving in wetter areas, such
as cup plant and prairie dock. Versatile grasses such as Indian
grass were planted uniformly over the whole field. |

|
In 2000 it was mowed twice, and in 2001 prairie
plants were well established so that no further mowing was done.
However, there were still some annual weeds, wild parsnip, and
several patches of Canada thistle. Wild parsnip was hand-pulled
and the thistle controlled by mowing.
A good controlled burn was carried out in March
2002 and the prairie responded well. Excellent growth of prairie
grasses and forbs occurred in the summer of 2002, making this
an excellent source of seeds for further planting. It was burned
annually thereafter, although in 2006 the west side was not burned.
Eventually it will probably be burned on a three-year burn cycle,
but plans are to continue annual burning for the near future.
Annual weeds, wild parsnip, and Canada thistle are
no longer a problem. However, bird's foot trefoil (Lotus corniculata)
is a persistent perennial weed that is still a problem. At present
this legume is being hand-pulled, a slow, cumbersome job, and
if we do not bring it under control that way in a year or two
we will turn to herbicide.

Because of its convenient location next
to Pleasant Valley Road, the Pocket Prairie is an excellent location
for educational activities. In fall 2003 a group of Girl Scouts came
to collect seed on a fine October day. (Kathie Brock explaining the
seed collecting process.) |
| The Pocket Prairie has developed
into an outstanding prairie, and because it is highly visible from
Pleasant Valley Road it serves as a showcase and demonstration area.
This prairie has a wide range of habitats, from wet mesic to dry sandy.
In 2004 all four native Wisconsin Silphiums bloomed and set seed:
S. integrifolium (rosinweed), S. laciniatum (compass
plant), S. terebinthinaceum (prairie dock), and S. perfoliatum
(cup plant). Sandy areas in the SE and SW corners have had extensive
shows of colorful lupine (Lupinus biennis). Asters and goldenrods
have done well. Old-field thistle (Cirsium discolor), pale
Indian plantain (Arnoglossum atriplicifolia), penstemon (Pentstemon
digitalis), prairie cinquefoil (Potentilla arguta),
prairie brome (Bromus kalmii), showy tick-trefoil (Desmodium
canadense), pale purple coneflower (Echinacea pallida),
rattlesnake master (Eryngium yuccifolium), Liatris aspera
and Liatris pycnostachya, black- and brown-eyed susan (Rudbeckia
hirta, R. triloba), spiderwort (Tradescantia ohiensis),
and golden Alexander (Zizia aureus) are all doing well. Indian
grass (Sorghastrum nutans) is the principal prairie grass,
although there are areas with big and little bluestem. See
check list below. |
