My alarm blares before sunrise and I quickly pull on my five layers of clothing for my upper body, my two pairs of socks, my face mask, my thermal underwear and jeans, and my North Face boots. I am now prepared to help overseed a prairie planting on this cool winter morning!
There is a slight cloud cover this morning and the temperatures are in the upper twenties — perfect conditions for what we need to do. I meet Jay Stacy, a land steward for Nachusa, at the Headquarters at 8 am. Jay is all prepared to overseed a 16-acre restoration that he first planted in the Fall of 2012. He has mixed 270 pounds of collected seeds* and placed them in eight 40–gallon barrels, already strapped into the back of a truck bed.
Bill Kleiman (Preserve Director) and Jay review the Kubota tractor operation and safety precautions before we depart. To do my part in keeping safe, I must make sure that I never stand behind or in front of the wheels when I help Jay. Getting squashed under a tractor tire is not on my agenda for the day, so I will follow this advice!
My job is to transport the seed out to the field, while Jay drives the tractor. To overseed with the tractor, rather than hand–seeding the entire field, Jay waited until the weather conditions were just right. The ground needed to be frozen to drive the tractor across the surface, as to not damage this beautiful restoration planting. So, Jay planned this overseed to follow four nights sub zero weather, on a day when the temperatures would then reach the low 30’s (so he did not freeze to death on the tractor!). The two inches of snow cover across the field just added a nice cushion.
The Seed Mixture
This is the 2nd winter overseed for this planting, the 1st occurring in the 2013 winter. For this overseed, Jay prepared three separate mixes, gauged to the soil type and drainage of the various parts of the restoration. The mixes contain forbs, sedges, non–dominant grasses and 40 pounds of Little Bluestem grass. Generous amounts of Leadplant (Amorpha canescens) and Northern Prairie Dropseed (Sporobolus heterolepis) were in all three mixes.
This mix targets gravel soils and contains species like: Downy Yellow Painted Cup (Castilleja sessiliflora), Purple Prairie Clover (Petalostemum (Dalea) purpureum), and Pale Purple Coneflower (Echinacea pallida).
One area in the planting turns out to be wetter than first thought in 2012, so plants that like the wetter side of mesic** were added to this mix. Some of the moisture–loving plants included are Mountain Mint (Pycnanthemum virginianum), Golden Alexanders (Zizia aurea), Rattlesnake Master (Eryngium yuccifolium) Gayfeather (Liatris Pycnostachya), and Tall Coreopsis (Coreopsis tripteris).
One area in the 16–acre planting has sandy soil, so Jay created an overseed mix with some of these plants: Prairie Coreopsis (Coreopsis palmata), Western Sunflower, (Helianthus occidentalis) and White Aster (Aster ptarmicoides).
Pulling a pendulum spreader behind the tractor, the overseed planting was finished in early afternoon with a good seed distribution across all three areas. Jay accomplished all the overseed work while I provided him with coffee, lunch, a warm truck and some comic relief.
While Jay collected the majority of seed, his efforts were greatly enhanced with the assistance of Tim Sherck, Jeff Cologna, Sheryl Honig, Tim Know, and yours truly. I cannot speak for the others, but I find seed collecting to be fun and relaxing, especially as we collect together. Also, seed collection is very rewarding, for when I see the new restorations in bloom, with butterflies, birds and bison savoring my efforts, I know I have done my part to restore the land back to its native state.
