Whippoorwill Farm Preserve
Mettawa
Open Lands Association (MOLA) is partnering with the Village of Mettawa to natively landscape our village's historic Whippoorwill
Farm Preserve. Seven acres of highly dense buckthorn have been transformed into a prairie/wetland complex. The farm is located on the NW corner of Riverwoods
Blvd. and Rt. 60.
IN THE FUTURE: Over the years
we will transform the current landscape into rolling prairie/wetland of native flowers and grasses with the Mettawa trail
and resting benches meandering throughout.

RESTORATION UPDATE 3/11Three contractors are working at Whipporwill Farm Preserve: Integrated Lakes Management (ILM), Tallgrass Restoration
(Tallgrass) and DePaul University (DPU). ILM is working the eastern area, Tallgrass is working the western area and
DPU is performing scientific research on the northern end of the site along Riverwoods Blvd. This spring 2011, ILM successfully burned their portion of WFP. Keep your eyes open to
see how marvelously a prairie responds to the burn - should be beautiful this summer! In the fall of
2010, Tallgrass removed the pasture grass by burning and broadcast native seed to freeze during
the winter and make its way into the soil with the freezing and thawing of spring. BE PATIENT ON THE WESTERN FRONT ! The prairie seed has set into
the soil on the western side of of WFP. This spring it will germinate, but most of its growth will not be noticed for
three years. For the first three years prairie plants put most of their growth into their roots to ensure they have adequate
nutrient and moisture resourses. Around year 3, more likely year 4, the prairie plants will exploded above ground into
full view for you to enjoy their beauty. It's that old cliche, good things take time.

Whippoorwill Farm Preserve History
Whippoorwill Farm Preserve (WFP) can be sited on a 1939 aerial photograph.
The restoration site was historically used as a riding arena and for livestock at least as far back as 1939 until the early
1990's, when the farm was left fallow. What followed was the growth of an infamously thick stand of young buckthorn.February 6, 2007 buckthorn demolition began
with contractors Integrated Lakes Management (ILM) and Tallgrass Restoration. As prescribed by MOLA, each contractor
is using a different demolition method and the success of each method will be monitored closely over several years.
De Paul University Professor Liam Heneghan and assistant Lauren Umek are evaluating and monitoring the site using scientific
methods to validate the success of the different restoration methods.
Buckthorn removal was completed in early
April 2007. It was quite a challenge to get rid of 20 to 30,000 buckthorn trees per acre. In late spring Tallgrass
Restoration turned over the soil, incorporating the chipped buckthorn into their 3 acres of soil. They then seeded using
a pasturing mix. In 2010 the pasture will be converted to natives. ILM let nature take it's course with
no soil disturbance and followed by summer herbiciding of buckthorn resprouts on its 3 acres. For both contractors, the weather played havoc on seed
germination, so reseeding occurred over the winter and into the spring of 2008. In September 2008, Liam, from DePaul
University, harvested corn from his corn plots, and continues to test the soils and perform plant transects on all of
his test plots.
