Project Introduction and Background:
Information on the Organization:
The Nina Mason Pulliam EcoLab property is a 55-acre natural area on the
campus of Marian University in Indianapolis, IN. Environmental restoration began
100 years ago when James Allison hired Jens Jensen as a landscape architect.
Since then, Marian students, K-12 school groups, and the general public has
continued to care for the EcoLab. Marian University students and faculty use it in
their classes as a site for hands-on experiences in the natural environment along
with undergraduate research and internships. They also host science programs
for all ages to increase knowledge and appreciation for the environment.
Mission for Project:
The Nina Mason Pulliam EcoLab encourages exploration of science and
stewardship of the environment. This project is to restore the recreational turf
grass to a prairie to diversifying the flora and fauna of the EcoLab. Installing
native plant species will diversify the animal and plant species while bringing a
more eye-catching, natural look to the area. By successfully restoring this area;
insects, pollinators, and monarchs will thrive. This area would be used to
educate the public on how a prairie could be resorted, while giving a beautiful
landscape to anyone touring the EcoLab for recreational use.

General Information:
The site is located on the Campus of Marian
University in the south part of the Nina Mason
Pulliam EcoLab in Indianapolis, IN. It is
bordered by the Access Road to the
northeast, the Jenson North Shore Trail to the
south, and the Rustic Trail to the west seen in
figure 1 to the right. Figure 2 shows the 4.36
acres of turf grass surrounded by beautiful
habitat types such as wetlands, prairies, bluffs,
and lowland forests.

An aerial photograph of the site is
seen in figure 3. This shows
Crooked Creek flowing from the
north to south, then curving
towards the east and Cold Spring
Road. The prairie is just south of the
site followed by the main pond
separating it from the escarpment.
Much of this area was turned into agriculture during the 19th century from its
natural deciduous forest like most of central Indiana at that time.
History of the Site:
The EcoLab got its topography from the latest glacier period about 12,000 years
ago. The glacier deposited till multiple times within its impervious layer which
created the Tipton Till Plain that makes up Central Indiana. The post-glacier
flooding carved out the steep escarpment that exposed the impervious layer
where the springs flow through. A vast area of deciduous forest covered the
land with dominant species such as Sugar Maple, American Beech, Ash,
Hickory, and Oak up until the 19th century when it was converted to an
agricultural field for farming. It remained this way until James Allison bought the
area in 1910 and hired Jens Jensen to restore the land. Jensen was innovative in
restoring the land with native natural groupings of species, man-made lakes,
wetland areas, and large meadows. Jensen used native plants such as Hard

Maple, Witch Hazel, Sagittaria, Hibiscus Moscheutos, Hawthorn, Elderberry, and
Dogwood to bring alive this beautiful landscape. Allison maintained this
landscape until his death in 1928 which then was acquired by the Sisters of St.
Francis of Oldenburg in 1937. As Marian College expanded, the desire for using
the EcoLab for educational purposes also grew. By the spring of 2000, restoration
efforts were conducted by Marian College led by Dr. David Benson to revive
Jensen’s vision of the area. Invasive species such as honeysuckle, bittersweet,
and buckthorn occupied much of the EcoLab which required to be removed.
These exhausting efforts along with several large planting projects have made
the Nina Mason Pulliam EcoLab the wonderful natural area it is today, where
children and students can learn to explore and care for the environment.

Major Features:
The major areas surrounding the project site consist of the bluff, the wetlands,
the lowland forest, and the
prairie. The bluff is located in
the south part of the EcoLab
and consist of Hennepin fine
loam soil seen in figure 5 and
6. This soil is deep and well
drained and is low in organic
matter. It has a rapid runoff
due to a high moisture
capacity and moderate permeability which
makes it susceptible to erosion. It ranges from
light to deep shade along the bluff. Black
Walnut, Sugar Maple, Basswood, White Ash,
and Hackberry make up the canopy for the
shaded bluff. The shrub layer consists natives
such as Wild Hydrangea, Elderberry,
Greenbrier, Riverbank Grape, and Forest Grape along with non-native species
such as Privet, Common Buckthorn, and Oriental Bittersweet. Restoration efforts
continue to reduce these non-native species from invading. The Lowland Forest

that borders the site to the west and the north consist of Sloan silt loam also
depicted in figures 4 and 5. This soil is deep and well drained with low organic
matter with a slow runoff. It is vulnerable to flooding and has a pH range from 6.8
to 8.6. Dominant trees such as Green Ash, Boxelder, White Mulberry, Sycamore,
and Cottonwood frame the lowland forest. Honeysuckle and garlic mustard are
invasive to this area which contribute to the continual restoration and
maintenance of the area. The project site is constructed of Udorthents, cut and
filled soil. This soil is assembled by different types of soil that was dug up and
deposited in this area. The pH ranges deom 8.4 to 8.8. This area has abundant
sunlight and is exposed to flooding from Crooked Creek to the north. The turf
grass was implemented in the 60’s and 70’s for practice fields for the sports
teams. The prairie around the site consists of grasses such as Fall Panicum, Old
Witch Grass, Yellow Foxtail, Giant Foxtail, Barnyard Grass, and Small Love Grass.
Other plants in these area are Reed Canary grass, False Sunflower, Autumn
Sneezeweed, and Canada Goldenrod. Japanese Honeysuckle, White Sweet
Clover, English Plantain, Yellow Sweet Clover, and Wintercreeper are invasive to
the area and disturb the natural habitat. Figure 6 shows the topography of the
project site as flat while showing the surrounding features having elevation
change.

Environmental Restoration
The EcoLab is home to a wide variety of healthy landscapes and habitats. By restoring
the turf grass area to a medium-stature prairie, it will contribute to the diversification of
the area. Insects, monarch, and birds will be attracted to the improved environment.
The prairie will enhance the amount rain water retained and allow for visitors to observe
the diverse landscapes surrounding this area. There are three steps that need to be
completed to ensure a healthy and thriving prairie. The first step would be to remove
the turf grass so that seed can be planted. This can be done by spraying 2% roundup
and allowing the grass to die off during the fall season. The second step would be to
use a seed drill to plant the seeds throughout the landscape. The third step would be to
manage the prairie. This can be done by spraying and removing invasive species and
performing a controlled burn on the area every couple years. This will kill off any of the
woody species from inhabiting the prairie while aiding to the natural process of the
prairie landscape. There are invasive and disruptive species found in the EcoLab and
specifically in the prairie landscape south of the project site that take top priority when
managing the landscape. In order to have a flourishing prairie, an extensive seed mix
must be dispersed after the turf grass has been killed and removed. The 4.36-acre
project site receive abundant sunlight and includes a cut and fill soil type containing
loamy sand, sandy clay, sandy loam, clay, and sandy loam clay soils. The hydrology
throughout the site varies some dry to wet. These characteristics are vital in determining
a seed mix that will blossom into a vibrant prairie. Wild Ryes will be used for early cover
during the prairie’s youth. Sedges will be used as a long-term cool season component
and Prairie dropseed and Little bluestem will be the dominant graminoids.

Amenities
Along with the restored prairie environment, amenities will be added to the site to aid in
the appearance and education aspect of the site. A nature trail will be added around
the perimeter of the site for a more personalized experience of the prairie. This trail can
be seen in purple in the figure below. Stone benches and tables will be dispersed along
the trail for an option to sit and admire the new environment. Bird baths will also be
added along the trail to enhance the ability to observe the added wildlife brought in
by the prairie. Observation binoculars will be stationed around the site to enrich the
view of the EcoLab.
