Controlled
burns: 6 and 14 November 2004 We had very successful
savanna burns on 6 and 14 Nov. 2004. The weather was very favorable
and we were able to burn all of our bur oak and white oak savannas.
Ten people participated in the burn on 6 November. We made good
use of the Prairie Enthusiasts pumper truck, as well as a new
off-road pumper unit installed on the rear of our Kubota tractor
(see photo). The total acreage burned was about 18 acres, predominantly
in the bur oak ridge-top savannas.
A brief spell of sunny dry weather on 14 Nov. 2004 made it possible
for us to burn the rest of our savanna, including the white oak
area. |

Our new Kubota-based pumper unit worked well on
mop-up, always an important part of an oak savanna burn. We could
drive right next to a burning log or tree and put out the fire.
The Kubota handles much like an all terrain vehicle but it is
more adaptable. The bucket is fastened to the tractor's three-point
hitch.
For the 14 November burn, we drove this vehicle to the top of
Unit 18 and used the 200 foot hose to create a wet line down the
ridge. |

We had our Annual
Labor Day field trip on Sept. 6, 2004. Over 20 people
attended, quite a few from Illinois. The weather was pleasant
and the prairies and savannas were in their full autumn glory.
Participants saw several areas of restored savanna where grasses
and forbs had become well established. Savanna grasses seen were
Elymus villosus, Elymus hystrix, Elymus riparius, and Bromus pubescens.
Among the many forbs were poke and purple milkweeds (forming pods),
lion's foot (Prenanthes alba), woodland Joe Pye weed (Eupatorium
purpureum), and elm-leaf and zig zig goldenrods (Solidago ulmifolia
and S. flexicaulis).
Also viewed were prairie remnants on the south-facing slope and
three planted prairies.

Seed collecting, September 12 and
28, 2004.
We had very successful seed collecting work parties on Sept.
12 and 28. Seeds collected included Elymus riparius, giant yellow
hyssop (Agastache nepetoides), wild bergamot (Monarda fistulosa),
woodland brome (Bromus pubescens), pale Indian plantain (Arnoglossum
atriplicifolia), black-eyed Susan (Rudbeckia hirta), yellow cone
flower (Ratibida pinnata), Indian grass (Sorghastrum nutans),
New Jersey tea (Ceanothus americana), pale purple cone flower
(Echinacea pallida), Upland boneset (Eupatorium altissimum), Old
field thistle (Cirsium discolor), Woodland thimbleweed (Anemone
virginiana), Rosin weed (Silphium integrifolium), and many others.
The weather has been excellent.

Seed collecting, October 17.
Our principal seed collecting target on October 17 was little
bluestem (Schizachryium scoparium). This characteristic
prairie species is plentiful on our south slope. Collecting was
a slow task, as seeds had to be stripped off the stems with a
comb. Fortunately, we had a nice group of volunteers and we collected
more little bluestem than we had ever collected before. |

Seed planting
21 November 2004
After two successful controlled burns, we started overplanting
the savanna areas with seed collected earlier in the fall. We
have over 20 acres to plant this fall, plus more in the spring
of 2005. Seeds of almost 150 species were collected, primarily
from Pleasant Valley Conservancy. A group of volunteers participated
in the first planting on 21 November. Because deer hunting season
had begun, everyone wore hunter orange, although we saw neither
deer nor hunters this day. |
