When restoration work was begun at Pleasant
Valley Conservancy there were a few fine prairie remnants
as well as 
some degraded savannas, woodlands, and wetlands. However,
grazing and other agricultural activities had caused a marked
loss in plant species.
In addition to removing a large number of invasive plants,
we worked hard to increase the diversity of native plant species.
This work has been quite successful. From an early estimate
of about 250 native plant species, our list has grown to over
400 species.
The number 250 is derived from a merger of plant checklists made by botanists who visited Pleasant Valley Conservancy before any restoration work had been carried out. These lists, presented below, were edited to remove any duplicates. The total list, which includes some weeds and other invasive species, has 270 species. It is estimated that about 250 of these species are plants native to prairies, savannas, woodlands, and wetlands.
The early plant species check lists given below were done
by different people at different times, and some of the Latin
names used, even for the same species, may be different. Plant
nomenclature is a complicated field, and different authorities
use different names. Continuing research in plant taxonomy
leads to altered nomenclatlures. Therefore, some of the names
used in these check lists may no longer be valid.
The first detailed plant check list for the
land that was to become Pleasant Valley Conservancy was carried
out by plant ecologist Brian Pruka in 1995. Pruka had just
finished his Master's thesis at the University of Wisconsin-Madison
working on a nearby oak savanna, and was familiar with the
area. His list was prepared for us as part of the early management
plan that Pruka prepared for the property. Pruka's
list contains 170 species,which included prairie, savanna,
woodland, and wetland species.
Even considering
the nomenclature problems mentioned above, and the fact that
surveys were made only in the summer, there are some noteworthy
species on the Pruka list, including a number with relatively high
Coefficients of Conservatism.
Species
List by Paul West
In 1997, we hired plant ecologist Paul West,
then working only part-time at the Nature Conservancy, to
further develop management objectives for the property. As
part of this work, West prepared another plant
check list. Although there was some overlap with Pruka's
list, West's list, with 136 species, added some additional
species.
Kathie
Brock's Species List for goat prairie (Unit 1)
Our best prairie remnant, Unit 1, was probably
never grazed. In 2002 Kathie Brock prepared
a species list for this prairie. At that time, this unit
had been burned six times. Noteworthy prairie species on Kathie's
list of 37 species include sky-blue aster, side oats grama,
purple prairie clover, showy and Illinois tick-trefoil, tall
boneset, flowering spurge, false boneset, small yellow flax,
fringed puccoon, violet wood sorrel, little bluestem, small
skullcap, blue-eyed grass, gray goldenrod, Indian grass, prairie
dropseed, spiderwort, and bird's foot violet.
Unintroduced Species
Missing From the Above Lists
There are a number of species that were originally
present at Pleasant Valley Conservancy that are not given
in any of these early lists. We know these species were present
because they are present now and we did not introduce them.
Of these, the most interesting are: White wild indigo, glade
mallow, Canada anemone, wood anemone, poke milkweed, silky
aster, white wild indigo, Bromus kalmii, large yellow
lady-slipper orchid, shooting star, wood betony, bottlebrush
grass, silky rye, Virginia wild rye, upland boneset, sweet
Indian plantain, prairie alum-root, great St. John's wort,
yellow star grass, seneca snakeroot, lion's foot, rosinweed,
cup plant, showy goldenrod, elm-leafed goldenrod, yellow pimpernel,
Culver's root, purple meadow-rue, angelica, spiderwort, bellwort,
prairie violet, golden Alexanders, and purple milkweed. Several
of these species are endangered, threatened, or of special
concern.
The
presence of purple milkweed (Asclepias purpurascens),
a State endangered species, is noteworthy. This beautful savanna
species was first found flowering in Unit 12B after it had
been cleared and burned. With further clearing and burning,
additional sites developed. Seeds of this species were never
brought in from elsewhere, although efforts have been made
(partly successfully) to get it established in new sites on
the Conservancy.
It turned out that a significant number of native
species were present on our property along County
Highway F. This north-facing slope had been periodically
mowed by county highway crews, but this mowing had been infrequent
enough that some important species were not eradicated. Species
that were present in relatively large amounts included New
Jersey tea, golden Alexanders, arrow-leafed aster, great St.
John's wort, great blue lobelia, fringed loosestrife, and
Culver's root.
Increasing Species
Diversity
Originally, our goal was to collect seed from
the remnants and transfer it to other sites on the property.
This work went in tandem with removal of invasive shrubs and
trees. The focus initially was on the south-facing slope where
large amounts of red cedar, planted red pines, elms, buckthorn,
honeysuckle, and other woody plants were removed. Removal
of these trees opened up "holes", into which seeds
collected elsewhere on the property were planted. This sort
of activity is on-going throughout the Conservancy.
As much as possible, we have used seed that
had been collected on our property. If no useful source was
found there, we collected seeds from nearby town roads, or
from other sites nearby. In only a few cases were seeds obtained
from more distant sites, although always from southern Wisconsin
sources.
In 1998, our first year of planting, we planted
20 species on the south slope that had been collected elsewhere
on the property. Only the lower part of the slope, which lacked
any significant savanna oaks, had been cleared. It was burned
in early April and planted a few days later, with seeds that
had been stored in the barn all winter. We had only limited
amounts of grass species, so this seeding was primarily of
forbs. As it turned out, burning had stimulated the growth
of pre-existing grasses, and little bluestem and Indian grass
flourished without planting.
Controlled burns played a major role in increasing
diversity, and the south slope has been burned almost every
year since restoration began. The photo here is from a burn
in March 2003.
First Planted Prairie At the
same time, we were planting completely new prairies on the
various small agricultural fields present at the site. These
small fields, amounting to a total of less than 15 acres,
had been entered into the Conservation Reserve Program (CRP)
in 1987. When our 10-year contract came up for renewal in
1997, we opted to plant prairie on two of these fields, which
gave us extra points in the evaluation of our CRP project.
Instead of purchasing seeds, we decided, as much as possible,
to collect our own seeds. Because our supply of seeds was
limited, the first year we planted only a single field to
prairie (Toby's Prairie). Although almost all the species
planted came from elsewhere on the property, a few species
that "should" have been in a tall grass prairie
were completely missing. These were obtained by trade from
the Madison Audubon Society prairie restorations at Goose
Pond. What we traded was volunteer work for seeds. Species
that we obtained from this source were: wild onion, Canada
milk vetch, white prairie clover, pale purple coneflower,
ox-eye sunflower, compass plant, and stiff goldenrod. All
the rest of the 70 species planted came from our own sources.
Indian grass, Sorghastrum nutans, is
an important species in a tallgrass prairie. It produces a
good prairie sod, and it provides great fuel for a prairie
burn. All of our Indian grass has come from our own property.
Initially, it was present in signficant amounts only on a
small prairie remnant high on the south slope (Unit 4), surrounded
by cedars and buckthorn, This tiny prairie of less than 1/2
acre was first burned in April 1998 and as a result the Indian
grass flourished. Seed was collected in the fall of 1998 and
used as part of the prairie seed mix for Toby's Prairie, planted
in November 1998. It has done exceedling well there and has
been the source of Indian grass seed for all of our subsequent
planted prairies, as well as for the open savanna areas.

2007: What Eleven Years Have Wrought
Restoration work at Pleasant Valley
Conservancy has proceeded at a steady pace.
As degraded savannas have been cleared, they
have been planted with seeds collected elsewhere
on the site. The planted prairies have turned
out to be excellent seed sources because of
the large acreages of relatively level land
where collecting is easy.
Only minimal work has been done
in the wetlands, which were initially in fairly
good shape. Minimal work has also been done
on the north-facing oak woods, which have plentiful
spring ephemerals and, except for a few areas,
only small amounts of invasive shrubs.
As of the end of the 2007 season,
over 400 native species are present at Pleasant
Valley Conservancy. Even more significant, the
floristic quality index
(FQI) has a value of 91.3, which is an impressively
high number.
Most of the species used for the
FQI calculation were not introduced but were
already here, although perhaps present in small
numbers. The most important work that we have
done is to remove the invasives, both woody
and herbaceous, thus providing habitat for pre-existing
species to spread. Controlled burns also have
played a major role.
We have increased diversity in
another way, by learning to identify the plants
and by exploring the Conservancy in great detail.
Often a rare species will be present in only
one or a few sites, and will be missed in any
casual walk-through. Further, restoration of
an area will almost immediately result in the
appearance of species that have not been seen
in that site before. They might well have been
present, but were suppressed by the great weight
of invasives.
As an example, shooting star,
a very desirable prairie and savanna plant,
is able to survive under the shade of exotic
bush honeysuckle, but is not readily visible.
Removal of the honeysuckles leads almost immediately,
usually in the first subsequent growing season,
to a great increase in the growth of shooting
star, many of which will flower (see photo below).
These were not planted, but burst in view after
their habitat was restored.
