A major goal of FLOW’s Lower Olentangy Greenspace Plan project was to inventory and map existing green and open spaces within the Lower Olentangy Watershed. This not only includes the obvious suspects such as parks, but also more obscure parcels such as conservation easements. Conservation easements are voluntary legal agreements between landowners and a qualified organization in which the landowner places restriction on the use of the property to protect the natural value of the land. Donation of a conservation easement typically protects land permanently while keeping it in private ownership.
Locating conservation easements proved harder than one might imagine. It might seem that one could go down to the local court house and simply request a list? Or perhaps one could go on-line to the county recorder’s database and do a simple search for easements? As a FLOW researcher recently discovered, it’s not quite so simple.
Some easements are old and discovery requires examining the ownership history of the land parcel and plat. A plat is a map of a land area, usually on the scale of a neighborhood and a parcel is a piece of land used for a single purpose (such as a park or a home). Essentially a plat map shows the collection of parcels that make up a neighborhood. While old plat maps may be photographed and stored electronically, original public land survey plats were hand drawn and the artistry and penmanship of each plat is unique. Some were drawn with color, others in shades of gray, and others in black and white. The level of detail captured in each plat map was dependent on the diligence and accuracy of the individual surveyors. Some surveyors created maps of remarkable detail, while other surveyors were less meticulous

Another challenge is that multiple organizations currently hold conservation easements. And no single clearinghouse exists. The Lower Olentangy watershed spans two counties and multiple government jurisdictions. Each has its own record keeping, its own type of database, and its own policies and procedures. To complicate matters, the costs of surveying land is sometimes prohibitive and electronic files are not even available or accurate.
So what role will conservation easements play in the future preservation efforts? As central Ohio strives to accommodate population growth and ensure enough green space – both for healthy humans and healthy functioning ecosystems, the conservation easement may need to evolve as well. Climate change and other potential landscape changes raise questions about the effectiveness and adaptability of permanent instruments.

October 2018, FLOW planted more than 100 trees between a variety of schools, including Gables, Maize, and Salem Elementary as well as Hamilton Stem Academy. Against all odds (cold, rain, and mud) these tree plantings were a success thanks to the efforts of Nisource, the Columbus Young Professionals, and other volunteers.
The transition from summer to fall is beautiful to witness. During this time of year, the temperature is comfortable and the leaves take on a spectrum of warm hues. However, late August to the end of October is also the optimal time to plant trees. One reason why is that the air is cooler than the soil this time of year. This encourages root growth without top growth, thus young trees are able to develop a sturdy root system before growing upward. Additionally, the moderate temperature and fall rain help the tree to hold in moisture, reduce the risk of it undergoing heat stress, and give it the required support to grow during the spring season. While some trees are easiest to grow in the spring, for many deciduous trees fall is the best time to plant.
Once a person knows what season to start planting, they’re going to need some tools to prepare. Assuming they’ve got a hole and a tree already, they’ll need a shovel, wire cutters, stakes, a stake pounder, and tree tie. Also, they should make sure that they’ve got 2 or 3 other people helping out, as even the smallest trees can have heavy root balls. The first step FLOW volunteers take when planting trees is removing any plastic ties or sacks on the trunk. Next, volunteers carefully roll the tree into the hole. After that, it’s time to cut the burlap sack covering the root ball. Volunteers use a wire cutter to remove the wire from outside of the sack, then remove the nails holding the sack together. After this, it is safe to bury the burlap sack along with the tree. Once the soil is distributed so as to fill in the hole, it’s time to mulch the tree. It is important to make sure to pull back the soil and mulch from the base of the tree trunk so that the root ball is exposed, as this helps the roots to absorb water and exchange necessary gases with the environment. Now it’s time to stake. Staking is done by pulling a stake pounder over the head and then ramming it over a stake. This is best done using your body weight to propel the pounder unto the stake. It is helpful to use the two stakes to straighten out the tree, if necessary. Finally, the tree should be tied to the stakes. Knots should be tight and wrapped around the grooves in the stakes so as to reduce the risk of the tie slipping. It is recommended that the planter leave extra tie so that there is enough to retie the tree if the knots come undone. Lastly, safely dispose of all waste, including any plastic, extra burlap, wire, or nails. After this process, the first steps have been taken towards planting a tree that will benefit the environment, the neighborhood, and the lives of individuals for years to come.
Five Reasons to Plant a Tree:
- Trees Absorb and Release into the Environment
This not only helps people to breathe, but in the long run, helps to combat climate change.
- Trees Improve Air and Water Quality
Trees absorb pollutants in the air and reduce runoff. Trees also reduce evaporation on shady lawns and release moisture into the air.
This helps keep the city cool on hot summer days and decreases the amount of energy used on air conditioning.
- Trees Increase Property Values
Trees can increase the property value of a neighborhood and attract business traffic.
- Trees Improve Health
It has been proven that trees help sick or injured people to heal. Trees are also good for mental health and well-being and help to reduce violence.
Central Ohio is growing and showing no signs slowing down. Updated projections are for another 600,000 more residents by 2050, increasing our region’s population to 3 million strong. In fact, Delaware County has been the fastest growing county in the state since the turn of the century. Such a prolonged population boom can fuel economic opportunity and optimism, but it also comes with challenges. They makes FLOW’s work on the Lower Olentangy Greenspace Plan all the more pressing.
A recent milestone in the project was the completion of a GIS (Geographic Information Systems) database of the Lower Olentangy watershed. GIS technology allows us to organize layers of information into a unique visualization of the watershed. This can reveal deeper insights, patterns, and relationships that help us make more informed decisions. In a recent presentation to our partners, Ryan Pilewski, Watershed Resource Specialist with the Franklin Soil and Water Conservation District, revealed some first insights from the recently compiled baseline data.
The initial analysis reveals about 20% of the Lower Olentangy watershed is covered by tree canopy, with substantially lower canopy cover in the highly urbanized areas. Research has shown at least 45% stream side forest cover is required for streams to have a healthy rating of “good”, so it’s something to examine if we want to adequately buffer our streams and rivers to ameliorate the impacts of future development.
Meanwhile the entire watershed is 17% covered by impervious surfaces. This represents the sum of roads, parking lots, sidewalks and rooftops that prevent water from infiltrating the surface and thereby increasing storm water runoff. Resulting problems include increased flooding, higher temperatures, sanitary sewer overflows and decreased stream health. With global climate change increasing the frequency of heavy rainfall events in Columbus and an intensifying urban heat island, it could be time to accelerate greener infrastructure options or even consider removing pavement from sensitive areas.
Only about 9% of the lands in the Lower Olentangy watershed have protected status. These lands include parks, trails, open and green spaces, and conservation easements. Ensuring we have adequate green space is of increasing concern amid the backdrop of strong population growth and development pressures. A growing body of scientific evidence confirms measurable human health benefits from green space. And it goes well beyond the need for healthy rivers and clean water. Natural spaces such as parks, urban forests, streams, and trails improve health, reduce stress, and can move the needle on disease prevention. So investing in green space makes us – and our communities – more resilient.
What can we take from these first data insights? The Lower Olentangy Greenspace Plan project was designed as a proactive planning effort to ensure that we have high quality natural space to protect the Olentangy watershed, as well as enough recreational space for healthy human needs. The metrics can illuminate the value of accurately inventorying our existing natural resources, provide a framework to educate our citizens, and be used as a tool for prioritizing future preservation efforts.
