Pasture Restoration with Native Warm Season Grasses

Pasture Restoration at Greenacres

You may have noticed some of the pastures at Greenacres looking a bit different than usual. This is because we used an herbicide treatment to eliminate the fescue found in these fields. We don’t typically use herbicides, but our research has found that in certain, limited circumstances, they are the least destructive and more effective method for restoring native grasses.

In 2019 we began converting some of the pastures at Greenacres Lewis Township into permanent stands of Native Warm Season Grasses through a joint research project with University of Tennessee’s Center for Native Grasslands Management. These native grasses, such as Big Bluestem and Indiangrass, were once widespread across the prairies of Ohio and the Great Plains, but almost all have been lost to land development and conventional tillage agriculture.

During this project we discovered that planting and establishing Native Warm Season Grasses can be very challenging. In the first year, the native grasses prioritize growing deep roots, and grow very few shoots above soil, leaving them vulnerable to being smothered and killed by weeds and other grasses if not managed correctly. Our research showed that targeted herbicide use to specifically reduce weed competition before planting is crucial to successful establishment of native grass species.

This spring we sprayed herbicide on fescue stands in certain fields on our Indian Hill farm in preparation for direct-drill planting of native grass seed before mid-June. No fertilizer or tillage is required. This summer we will monitor the seedlings and mow to reduce weed pressure if necessary to ensure good establishment of the Native Warm Season Grasses. Grazing animals will not return to these fields until we have had soil and forage laboratory tests that show no remaining herbicide residue.

We have set a goal to convert approximately 15% of our fescue pastures at our Indian Hill and Michaela Farm locations into Native Warm Season Grasses.

Native Warm Season Grasses are important to our generative agriculture practices for a number of reasons:

  • They offer excellent habitat for a wide range of grassland nesting birds.
  • They provide high quality forage to our cattle herds during the hot summer months.
  • They are native to our area and adapted to grow in shallow, low fertility soils.
  • They sequester large amounts of carbon through an extensive root system that can grow up to 8 feet deep.
  • Once established, the native warm season grasses will thrive for decades and reduce our need to plant short-term annual summer grazing crops each year such as sorghum sudan, buckwheat etc.

Prescribed Fire at Greenacres

Prescribed Fire at Greenacres

Fire as a Land Management Tool

As stewards to the land gifted to us by the Nippert family, Greenacres strives to utilize the best land management practices available. Fire has always been a part of the natural world, and returning prescribed fire to our landscape is an integral part of conserving nature, for the benefit of both wildlife and humans alike. Various plant communities found on our properties are dependent on fire to create a healthy, resilient, and biodiverse ecosystem. From the wildflowers of spring and summer, to the oak trees feeding its acorns to the animals of the forest, to grasslands hosting quail – all are dependent of periodic fire to keep the ecosystem in balance.

Conducting a Prescribed Burn

As a land management tool, prescribed fire requires careful planning and thorough training to ensure the safety of persons and property. Greenacres staff members who plan and lead prescribed fires are certified through the Ohio Division of Forestry and have years of experience. Staff trainings are held to ensure all those who are working these fires are knowledgeable and competent in their roles. Permits are issued through the Ohio Division of Forestry, the Ohio EPA, and local fire departments, holding Greenacres to the utmost standards while conducting prescribed fires.

Greenacres conducted two prescribed burns in Indian Hill in 2022 – for more information on those fires, please click here

Improving Garden Production with Caterpillar Tunnels

Our garden team is excited to have nine operational caterpillar tunnels. These plastic tunnels are designed to extend our growth and harvest season by protecting crops from wind and weather. Our Manager of Garden Operations, Ian Zeglin tells us that, “these tunnels allow us to get our crops outside earlier in the spring and to keep our crops longer in the ground throughout fall.”

In the winter, the tunnels provide protection from the wind and cold-weather elements. Although we have several varieties of cold-hardy crops that are able to survive Ohio winters, the tunnels allow these plants to thrive in a harvestable manner. In the summer, the tunnels are then used for warm weather crops such as tomatoes and peppers. These crops love heat and the tunnels help provide a warm environment in which they can thrive. The tunnels also help keep leaves dry so that we don’t get diseases like late blight. Ian Zeglin also mentions that “with their light-weight and compact design, these tunnels can easily be moved and utilized all over the farm!”.

What's New at Michaela Farm?

Indian Hill isn’t the only campus with new high tunnels. Our garden crew at Michaela Farm is also adding them to the St. Mary’s Road gardens. In addition to vegetable production improvements, we are gradually reintroducing more livestock back to the farm. Last month, we added a mobile coop to the property, along with a flock of 150 laying hens and two roosters which means eggs have returned to the store! Mobile coops benefit the pasture as the manure fertilizes the ground and the chickens eat insects and break up the soil with their scratching. You can click here to see a video tour of the coops we use and learn more about our egg production practices. 

We are looking forward to more vegetables year round at Greenacres Michaela Farm!

Turning Geography into Data

Geographic information systems (GIS) is a way to combine data and maps to reveal new insights. The research department recently begun using GIS to broaden its capabilities through experiment site planning, mobile data collection, and data modeling. “Maps and GIS allow us to quickly get a snapshot of the land, using a combination of field-collected and remotely-sensed data. With a better understanding of our properties, our researchers and land managers can more effectively achieve their goals,” says Research Assistant, Luke Weyer.

One use of GIS is the detection of Amur honeysuckle via satellite. Amur honeysuckle and other invasive shrubs were removed at Greenacres starting in 2017. Amur honeysuckle maintains a competitive advantage over native plants by keeping green leaves and photosynthesizing after most native trees/shrubs have lost their leaves. Because of this, satellite imagery from November can “see through” the bare canopy and distinguish green honeysuckle leaves from the surrounding dormant vegetation.

As with all models, the data presented by GIS should not be immediately accepted as fact; there will be sources of error. These maps can, however, be used as a starting point to notice broad patterns (like the overall success of the removal), indicate areas on property where honeysuckle presence needs to be confirmed/rejected, and identify where honeysuckle is most likely to re-enter the property.

Above is the output map of that analysis, modeling where honeysuckle (yellow) may be present. Notice the lack of honeysuckle present on Greenacres’ property in comparison to surrounding areas, especially along the right edge of the property.

Electric Lawn Mowers

After a year long trial of electric automatic lawn mowers, Greenacres has purchased an additional six. These electric mowers are quieter, safer, and require less maintenance than traditional lawn mowers, making them a great fit for our “green” initiatives. Our goal is that they outlive our older-model lawn equipment to prove their sustainability. Our Buildings and Grounds Director, Alex Saurber informs us, “after several months of research, we are very excited to move forward with the additional automatic mowers. With these new mowers at work, it frees up a lot of time for our estate crew to start new projects, including ‘green’ ones. We are proud to be taking steps towards a greener future and look forward to reduced emissions when maintaining our lawns.”

Maple Syrup Production at Greenacres

Did you know North America is the only place in the world where maple syrup is produced?  In fact, the majority of maple syrup comes from Canada. However, there are twelve maple-producing states in the US, and Ohio is ranked in the Top Five. In southern Ohio, sap begins to flow in late January or early February. The best production happens when the temperatures reach over 40F during the day and below 32F during the nights.

We tap sugar maple trees as this species has the highest sugar content of all maple species. It requires over 40 gallons of sap to produce 1 gallon of pure maple syrup!  Each maple season, students visit Greenacres to experience the entire maple syrup process through our field trip programming.  This year we shared the joy of maple syrup production in our new Sugar Shack at our Old Church site. This is where we begin the process of evaporating and producing maple syrup from the sap we collected in our “sugar bush.”

Preserving Herbs Through Dehydration

Dried herbs are a great way to add flavor to your cooking, especially when fresh options are not available. Drying preserves the flavor of the herbs, reducing waste and maximizing the yield of our plants during the growing season. We were able to introduce these to our customers thanks to the efforts of our Garden Apprentice, Abby McGuire. Garden apprentices are required to select a project for personal development and Abby selected dried herb production. We’re very proud of what she accomplished!  

We grow a vareity of herbs, like sage, thyme, lavender and chamomile. The plants are packed with oils and flavors and are harvested by the garden team early in the day alongside our vegetables. Post-harvest care varies based on the characteristics of each herb. Some herbs like sage and rosemary benefit from the leaves being removed from the stem before drying, while thyme is small and tender, better suited to dry with the leaves on the stem, and then stripped after drying.

We worked with the Health Department to develop kitchen protocols to ensure food safe practices are followed during the dehydration and packaging process. It can take anywhere from 8-12 hours to create a finished product depending on the variety of the herb being dehydrated. Herbs that are woody, like rosemary, take longer to dry fully than delicate herbs like basil and dill. Once dry, the herbs are carefully weighed and packaged into individual packets, heat sealed, and labeled. We are excited to bring these little glimpses of summertime freshness into the Farm Store!

Winter Equine Program

The 2023 Spring Session is full. We still have an active waitlist, so if you are interested in enrolling your children in the lesson program we invite you to join our waitlist. We enroll riders between the ages of 8-18. 

School Horse Spotlight

Sol is a 24 year old warmblood and has been a Greenacres school horse since 2012. Sol is a jack of all trades in our lesson program. He is quiet enough to teach the beginners how to walk and trot, but he can also teach riders how to jump. During show season, Sol enjoys traveling to horse shows with our Pony Club members. When Sol is not teaching lessons or traveling to horse shows, you will find him hanging out with his best friend Quest during turnout.

In 2016, Interlochen’s Board of Trustees adopted a sustainability resolution, pledging to “create an environmentally friendly and sustainable campus” at Interlochen Center for the Arts. In the six years since, the organization has constructed a botanical lab and community garden; initiated campus-wide recycling and composting programs; installed water-saving appliances and restroom fixtures; established sustainability education programs for Interlochen students and members of the local community; and donated thousands of pounds of organic fruits and vegetables to the local food pantry at Redeemer Lutheran Church. In 2019, the United States Department of Education designated Interlochen Center for the Arts a Green Ribbon School in recognition of the organization’s efforts to reduce its environmental impact, improve the health and wellness of its students and staff, and provide effective environmental and sustainability education. Later this year, Interlochen will also release its first-ever formalized climate action plan, which will outline further steps toward mitigating climate change and reducing the institution’s carbon footprint.

The film is set to begin production this fall, with a goal of premiering at national film festivals. It will then be made available to the public through a streaming platform and community screenings.
