Pleasant Valley

In fall 2005 we have kept busy seed collecting
and preparing new areas for prairie planting. This has been one
of the driest fall seasons on record. From the middle of August
until the middle of September there was no rain. Since mid-September,
rain has occurred, but not in large amounts. Despite the drought,
we have obtained good seed production of most species except in
our dry prairie remnants. In the latter, little blue stem (Schizachyrium
scoparium) has suffered the most. Although little blue stem
flowered well, an analysis of seed set under the dissecting microscope
showed that seed production was only 10% or less. This has forced
us for the first time to purchase seed of a prairie grass. Up
until this year, all of the grasses planted at Pleasant Valley
Conservancy have come from collections elsewhere on the property,
or from nearby roadsides. (We made certain that the little blue
stem seeds we purchased were from southern Wisconsin genotypes.)
Flowering and seed set has been quite good in our wetland. This
is reasonable since the wetland is fed primarily by underground
springs and seeps, which have remained at usual water levels.
Fortunately, one of the major areas we are planting is a wet-mesic
area adjacent to the wetland, and most of the species to be planted
are coming from this wetland. We have not yet given this area
a name, and are temporarily calling it the "marsh edge."
It is a long narrow area adjacent to Pleasant Valley Road and
is 4-5 acres in extent. |

Kathie Brock and Susan Slapnick examining our
wetland. Because of the excellent
burn done this spring by the U.S. Fish and Wildlife Service,
we have had outstanding plant development. The large purple stalks
of Joe-pye-weed (Eupatorium maculatum) shown here are
an example of the profusion with which wetland plants have flourished
this summer.

|
Because of the excellent seed set, large amounts
of Joe-pye seed could be collected by Madison Audubon Society for
use in a major wetland planting (Susan Slapnick collecting). |

The Land Trust Alliance, a national coalition
of land trusts from throughout the United States, had its annual
rally in Madison October 14-17, 2005. One of the field excursions
was a bicycle trip led by Peter McKeever into the Driftless Area
of western Dane County. This trip included a visit to Pleasant
Valley Conservancy, where the participants were able to examine
at first hand our restoration work. They were also able to discuss
with us how the Savanna Oak Foundation, Inc. is organized in part
as a land trust to provide permanent protection and management
of Pleasant Valley Conservancy. The photo to the left shows the
participants arriving at Pleasant Valley Conservancy. The large
prairie remnant in the background is dominated at this time of
year by little blue stem grass. |

The kestrel (Falco sparverius)
is a small insect-eating hawk that lives in open country and woods
edges. Kestrels nest in tree cavities and may also rely on nest
boxes. Several years ago we had a kestrel nest in a box mounted
high in a tree. It was fun to watch the bird hover over a field
with rapidly beating wings, searching for an insect. However, the
tree-mounted boxes were hard to reach for cleaning. This fall we
installed two new kestrel boxes using a two-part pole that permits
access to the boxes. The two parts of the pole are fastened with
carriage bolts that can be loosened so that the pole can be rotated
and brought to the ground. This installation was suggested to us
by Mark Martin of Madison Audubon Society. |

Buildings
at Pleasant Valley Conservancy
|
|
|
This is a Fall 2005 update on the
buildings at Pleasant Valley Conservancy. We have purposely avoided
any significant building projects. Buildings are expensive, and
tend to become a major focus of activity. We prefer to put our
resources into restoration work.
The "shack" in the photo was on the property when we
purchased it 25 years ago. It was constructed by the former owner
from a pig pen, and is a single-room affair. It has electricity
but no running water, and is heated only by a wood stove. We have
a small library of plant identification manuals, a dissecting
microscope, and a refrigerator. We store brush cutters, a leaf
blower, the console for our weather station, and some hand tools.
This is where we have lunch every day we are in the field. Among
other things, lunch is the time when we discuss upcoming projects.
Visitors sometimes drop in.

Near the cabin, painted to match, is the well
house, a very important facility. Although the water is not drinkable,
we use lots of water for diluting herbicides and for filling our
pumper units for controlled burns. A lawn sprinkler keeps our
nearby forbs garden from drought.
Behind the well house, painted to match, is the privy, another
important facility. This one is brand new in 2005, and was built
to replace the old one that was housed in a corn crib (see photo
below).
|
 |
|
The corn crib is the only building remaining from
the original Lockwood farm. It formerly housed the privy, and has
probably been used by generations of land owners. Because of our
interest in history, we are reluctant to tear it down. Obviously,
some day this corn crib will no longer be with us. Until then, we
enjoy having it on the property. |

This photo shows all the buildings at Pleasant
Valley Conservancy. (The "shack" is mostly hidden behind
the barn.) The small barn was installed by the former owner to
keep his horses. It is about 35 years old. We installed a concrete
floor and built a work shop in one corner. Here we store our Kubota
tractor (for mowing), our Kawasaki Mule (for herbicide spraying,
controlled burns, and general utility), our Ferris walk-behind
mower, and our pumper unit (for controlled burns). We also dry
seeds on the concrete floor and hang them from the rafters to
overwinter.
This photo looks across a small part of our wetland toward the
south slope, where prairie remnants and oak savannas dominate.
We have a complete John Curtis vegetation continuum on the Conservancy. |

Pleasant Valley Creek is a small spring-fed watercourse
that drains about 3 miles of Pleasant Valley. It generally runs
clear and has lots of watercress (Nasturtium officinale),
an attractive albeit nonnative and potentially invasive plant.
However, most of the water in our wetland does comes not from
the creek, but from the numerous springs which well up throughout
the property.Groundwater here is reliable and plentiful. |

One of the joys of our oak savanna are the patches
of hazelnut (Corylus americana), which turn a deep red
in October. Although we can hardly ever pick hazelnuts (the squirrels
always beat us to it), these shrubs are the most important species
in the savanna shrub layer. When their leaves turn red, we are
able to easily tell how common they are in our savannas. And their
color really dresses up the landscape.

Another fall scene: A nice patch of woodland rye
(Elymus riparius) flourishes in this area of the White
Oak Savanna. Also present are the dark seed heads of giant yellow
hyssop (Agastache nepetoides), a State Threatened plant. |
