Our Students Work in Five Environmental Preserves

Ashland University also manages five environmental preserves that support undergraduate and faculty research and habitat conservation. They are also used regularly by our classes. The Preserve Manager Is Dr. Richard Stoffer. Students may become involved in studies of the biological and physical attributes and processes that characterize these preserves. Each preserve contains unique habitat and wildlife and thus offers a variety of study opportunities.

  • Black Fork Wetlands (diverse wetlands and upland habitats)
  • Canfield (stream)
  • Dayspring (stream and forested ravine)
  • Rupp (restored prairie)
  • Stoffer (old field and mature forest)

Our Facilities and Instrumentation

The Kettering Science Center houses the Department of Biology/Toxicology and the Department of Chemistry/Geology/Physics, which together offer the interdisciplinary Environmental Science Program.

A major addition and renovation of the Kettering Science Center was completed in 2006. A new 2,500-sq.ft. state-of-the-art greenhouse and an additional research lab was completed in 2008. Altogether these facilities include new and renovated lab and teaching space and office suites that house faculty where students can find them, as well as several specialty rooms for specific research tools and facilities (e.g. vivarium, research microscopy, tissue culture).

Kettering teaching and faculty/student research laboratories provide students with access to modern equipment and instrumentation that are used for the analysis of environmental samples:

  • GC/mass spectrometer

Preserves

Our Students Work in Five Environmental Preserves

Ashland University also manages five environmental preserves that support undergraduate and faculty research and habitat conservation. The Preserve Manager Is Dr. Richard Stoffer. Students may become involved in studies of the biological and physical attributes and processes that characterize these preserves. Each preserve contains unique habitat and wildlife and thus offers a variety of study opportunities. The five preserves are located in the Unglaciated Allegheny Plateau (Dayspring Preserve) and the Glaciated Allegheny Plateau (Black Fork Wetlands, Canfield, Rupp, Stoffer).

Black Fork Wetlands (diverse wetlands and upland habitats)

In 1998, with the help of an anonymous donor, Ashland University purchased 38 acres of wetland six miles south of campus on U.S. 42. In 2004, an additional 260 acres was purchased with a grant from the Clean Ohio Conservation fund and additional support from a matching grant.  In 2018, seven acres were added with support from generous members of the community. This preserve has a mix of several habitats, including buttonbush swamp, swamp forest, marsh, riparian corridor, and upland areas. Species observed at the preserve include beaver, trumpeter swans, bald eagles, soras, and sandhill cranes. Wetlands are habitats with high ecological value. Floodplain areas help slow, absorb, and filter water moving downstream during periods of high water and thus provide valuable ecosystem services. They have the highest biological productivity of terrestrial habitats outside of rainforest areas. The inclusion of 305 acres in the Black Fork Wetland Preserve lessens its susceptibility to outside activities that might affect it and also provides many species with the larger habitat areas needed for maintenance of their populations.

Canfield (stream)

In 2002, a one-acre preserve with deciduous forest and a running stream was donated by Mike and Judy Canfield. This preserve, a short drive from campus on U.S. 250 north, provides a cobble-bottom stream habitat not present in the other preserves close to Ashland.

Dayspring (stream and forested ravine)

In 2004, Dr. Lewis Smith (Ashland University'50) and his wife Ardeth (Kline, Ashland University'52) donated 50 acres of land in Coshocton County for use as an Ashland University environmental preserve. This property is located in an unglaciated area of Ohio, and thus contains different habitats and geological formations than are found in the other Ashland University preserves. Features include mature deciduous forest and a deep ravine with a healthy stream that flows across much of the property.  In 2012, a grant from the Schooler Foundation allowed for a major renovation of the field station and upgrades to the access bridge.

Rupp-Stahley (restored prairie)

In 1996, a grant from The Fran and Warren Rupp Foundation of Mansfield, Ohio, enabled Ashland University to purchase a 8-acre preserve three miles north of town on Ohio 511.  The preserve was expanded to 9+ acres in 2017. Three habitats are being managed here: second-growth forest, old field, and two acres of restored prairie.  Controlled burns have been done with the help of volunteer students and faculty. In 2017, the Rupp Preserve was made a study site for a state-wide research project investigating Ohio bumblebees and their habitats. This project is led by the "Ohio Bee Team," aka a group of researchers from the University of Akron and Ohio State University.

Stoffer (old field and mature forest)

In 1999, Ashland University established the Thomas and Donna Stoffer Environmental Preserve north of Ashland on U.S. 42. Donated by Thomas (Ashland University'44) and Donna Stoffer (Ashland University'43), this preserve contains 10 acres of old fields and 20 acres of deciduous forest with streams.

Outreach

Working with the community

The Environmental Science Program supports and co-sponsors a variety of outreach programs targeted K-12 students and teachers and the regional community. Many of these efforts use the Black Fork Wetlands Environmental Studies Center or another of the five Ashland University Environmental Preserves to support hands-on experience in natural ecosystems.

Community Programming Includes:

Black Fork Wetlands Environmental Studies Center

The BFWESC was established in 2005 after a major grant from the Clean Ohio Fund allowed for substantial expansion of conserved habitats included in the Black Fork Wetlands Preserve. Funds also supported boardwalk and parking lot construction that allows for public access to this 300-acre preserve. Since 2005, the BFWESC has sponsored or co-sponsored numerous school groups from Ashland, Richland, and surrounding counties, as well as teacher development workshops promoted by the Environmental Education Council of Ohio.

Environmental Lecture Series

Established in 1991, the Lecture Series is designed to provide students, faculty and residents of North Central Ohio with the opportunity to interact with prominent environmental scientists from around the country. This series is free and open to the public, and has been supported by grants from GTE Foundation, the Fran and Warren Rupp Foundation, the Lubrizol Foundation, and support from Ashland University. The lecture series is publicized in local newspapers, and current lectures are archived for viewing on our website.

High School Lecture & Luncheon (9th-12th)

Each year, 100 high school students from area high schools are invited for a talk by a prominent environmental scientist, followed by a luncheon and question period to provide them with the opportunity to interact with the speaker. The only cost to the high schools has been to provide transportation to the Ashland University campus. This program was initiated in 1999 with a grant from the Fran and Warren Rupp Foundation, and has continued each year since thanks to a variety of sponsors.

Kettering Scholars (8th)

This program was established in 1999 for honors eighth grade students from Ashland Middle School. Fifteen to eighteen participants experience a lab with a different faculty member each month during the academic year. Field-oriented labs have included analysis of pigments involved color changes in leaves in Fall, spring wildflowers at Fowler Woods, and aquatic ecology of the Black Fork Wetland Preserve followed by microscopic examination of the samples in lab. Kettering Scholar alumni (12th grade) return during high school for advanced lab activities.

Naturalist on Duty

Starting in 2016, the Naturalist on Duty program has been offering short programs and informal learning options in an open-house format. These events are offered monthly on a Saturday during summer and fall. AU environmental science faculty collaborate with Ohio Certified Volunteer Naturalists to host visitors.

Nature Walks With Community Groups

EVS faculty members have hosted nature walks with members of regional community groups for many years. A recent example was the day trip planned with the Mohican Native Plant Society to explore plant diversity at the Dayspring Preserve in Coshocton Co.

Mohican District Science Day

Mohican District Science Day is the district science fair for students in grades 5-12 in schools of Ashland, Richland, Wayne, Holmes, Medina, Lorain, Huron, and Erie counties. Students who enter District Science Day must receive superior ratings at science fairs held locally at their own school, county, or school district. Projects that have followed Ohio Academy of Science (OAS) standards from students who come from schools where local science fairs are not held are also welcome providing you contact the Director for special permission. Students receiving superior ratings at the district level may then be selected to compete in the Ohio Academy of Science's State Science Fair at The Ohio State University on May 11, 2020.

Toxicology student presents research on Pesticide Analysis

Cillian Donahue, a senior Toxicology and Biology major (with a concentration in Forensic Biology) from Strongsville, had the opportunity to present her research on “Using Passive Sampling as a Method for Pesticide Analysis” at the recent National Collegiate Honors Council Conference in New Orleans. Cillian has been investigating a new method using silicone tubing to absorb pesticides from sediment for her Honors Capstone project. She is supervised by Dr. Jeff Weidenhamer (Chemistry) and Dr. Andrew Trimble (Toxicology).
Cillian writes that the feedback she received will be useful for other presentations of her research in the coming year, and that she was able to see projects that that Honors Students around the country are working on. While in New Orleans, Cillian had the opportunity to check out a couple of museums related to her scientific interests – the New Orleans Pharmacy Museum and the New Orleans Museum of Death, which has memorabilia related to famous crimes among other forensic-related topics. 
The New Orleans Pharmacy Museum (photos below) was located in a pharmacy that was founded in the 1800s. The building housed old pharmaceutical equipment and various questionable medications. Tinctures ranged from mixtures of cocaine and red wine, to heroin and sodas. In addition, there was no shortage of heavy metals, including lead coated pills for the rich, and lead baby bottles to sooth young ones. Overall, Cillian found the museum was very educational and interesting, particularly for Toxicology majors.

Ashland Toxicology and Forensic Biology major receives Ohio EPA scholarship

Senior Maria Kern is the latest AU Science student to receive a $2500 scholarship from the Ohio EPA’s Environmental Education Fund. Maria has conducted environmental science research as part of our University’s water monitoring program at our Black Fork wetlands preserve. More recently she has started a new research project with chemistry professor Dr. Jeff Weidenhamer. In the summer of 2018 Maria was part of the field research internship program at Central Michigan University. Maria is also a member of the University’s honors program and a Choose Ohio First scholar.

Maria writes about her new scholarship:
Winning the 2019 OEEF Scholarship was a great start to my senior year. This award provides valuable scholarship opportunities which allow natural science students with experience in environmental research to continue their education. This award will allow me to focus more fully on my classes and research without having to worry about covering the cost of books or any tuition not covered by other scholarships. Additional focus on my research will increase the quality of my capstone which I will be defending in the spring, and may create new job opportunities for me after graduation.
Maria is the 24th Ashland University science student to be chosen for the Ohio EPA scholarship since 2006, including four just last year....Read more

A Summer of Mammoths


Over the summer, Dr. Nigel Brush, Professor of Geology, has been kept busy identifying various rocks, fossils, and human artifacts exposed by recent heavy rains and flash floods here in NE Ohio. While this summer’s heavy rains were not good for farmers, as well as some home owners living near streams, it was a windfall for geologists and archaeologists as nature accidentally revealed some of the ancient treasures buried beneath the earth’s surface.

Mammoth tooth found at the Inn at Honey RunThe fossil that has generated the greatest interest was a mammoth tooth found by a twelve-year-old boy in a stream bed near the Inn at Honey Run, located a few miles outside the town of Millersburg in Holmes County. Nigel confirmed that this large tooth was indeed a mammoth tooth. He and Jeff Dilyard (a member of the Ashland/Wooster/Columbus Archaeological and Geologic Consortium) subsequently visited the Inn to examine the tooth and the find location. With permission from the Inn owner, Jason Niles, they surveyed the stream bed and banks upstream from the find site, but found no additional mammoth teeth or bones.
Two types of mammoth lived in Ohio during the Ice Age: Woolly Mammoth and Jefferson Mammoth. These mammoths had four large teeth (two upper and two lower). As the ridges on each tooth wore down by grinding grasses and small seeds, the tooth was shoved forward in the jaw by a new tooth until the old tooth fell out. Over their lifetime of 60-80 years, a mammoth would have six complete sets of teeth. Therefore, a single mammoth might lose some 20 teeth before developing its final set of teeth.
Another member of the elephant family that lived in Ohio during the Ice Age was the American Mastodon. Mastodons were slightly smaller than...Read more

Features include mature deciduous forest and a deep ravine with a healthy stream that flows across much of the property.  In 2012, a grant from the Schooler Foundation allowed for a major renovation of the field station and upgrades to the access bridge.

Rupp-Stahley (restored prairie)

In 1996, a grant from The Fran and Warren Rupp Foundation of Mansfield, Ohio, enabled Ashland University to purchase a 8-acre preserve three miles north of town on Ohio 511.  The preserve was expanded to 9+ acres in 2017. Three habitats are being managed here: second-growth forest, old field, and two acres of restored prairie.  Controlled burns have been done with the help of volunteer students and faculty. In 2017, the Rupp Preserve was made a study site for a state-wide research project investigating Ohio bumblebees and their habitats. This project is led by the "Ohio Bee Team," aka a group of researchers from the University of Akron and Ohio State University.

Stoffer (old field and mature forest)

In 1999, Ashland University established the Thomas and Donna Stoffer Environmental Preserve north of Ashland on U.S. 42. Donated by Thomas (Ashland University'44) and Donna Stoffer (Ashland University'43), this preserve contains 10 acres of old fields and 20 acres of deciduous forest with streams.

Outreach

Outreach

Working with the community

The Environmental Science Program supports and co-sponsors a variety of outreach programs targeted K-12 students and teachers and the regional community. Many of these efforts use the Black Fork Wetlands Environmental Studies Center or another of the five Ashland University Environmental Preserves to support hands-on experience in natural ecosystems.

Community Programming Includes:

Black Fork Wetlands Environmental Studies Center

The BFWESC was established in 2005 after a major grant from the Clean Ohio Fund allowed for substantial expansion of conserved habitats included in the Black Fork Wetlands Preserve. Funds also supported boardwalk and parking lot construction that allows for public access to this 300-acre preserve. Since 2005, the BFWESC has sponsored or co-sponsored numerous school groups from Ashland, Richland, and surrounding counties, as well as teacher development workshops promoted by the Environmental Education Council of Ohio.

Environmental Lecture Series

Established in 1991, the Lecture Series is designed to provide students, faculty and residents of North Central Ohio with the opportunity to interact with prominent environmental scientists from around the country. This series is free and open to the public, and has been supported by grants from GTE Foundation, the Fran and Warren Rupp Foundation, the Lubrizol Foundation, and support from Ashland University. The lecture series is publicized in local newspapers, and current lectures are archived for viewing on our website.

High School Lecture & Luncheon (9th-12th)

Each year, 100 high school students from area high schools are invited for a talk by a prominent environmental scientist, followed by a luncheon and question period to provide them with the opportunity to interact with the speaker. The only cost to the high schools has been to provide transportation to the Ashland University campus. This program was initiated in 1999 with a grant from the Fran and Warren Rupp Foundation, and has continued each year since thanks to a variety of sponsors.

Kettering Scholars (8th)

This program was established in 1999 for honors eighth grade students from Ashland Middle School. Fifteen to eighteen participants experience a lab with a different faculty member each month during the academic year. Field-oriented labs have included analysis of pigments involved color changes in leaves in Fall, spring wildflowers at Fowler Woods, and aquatic ecology of the Black Fork Wetland Preserve followed by microscopic examination of the samples in lab. Kettering Scholar alumni (12th grade) return during high school for advanced lab activities.

Naturalist on Duty

Starting in 2016, the Naturalist on Duty program has been offering short programs and informal learning options in an open-house format. These events are offered monthly on a Saturday during summer and fall. AU environmental science faculty collaborate with Ohio Certified Volunteer Naturalists to host visitors.

Nature Walks With Community Groups

EVS faculty members have hosted nature walks with members of regional community groups for many years. A recent example was the day trip planned with the Mohican Native Plant Society to explore plant diversity at the Dayspring Preserve in Coshocton Co.

Mohican District Science Day

Mohican District Science Day is the district science fair for students in grades 5-12 in schools of Ashland, Richland, Wayne, Holmes, Medina, Lorain, Huron, and Erie counties. Students who enter District Science Day must receive superior ratings at science fairs held locally at their own school, county, or school district. Projects that have followed Ohio Academy of Science (OAS) standards from students who come from schools where local science fairs are not held are also welcome providing you contact the Director for special permission. Students receiving superior ratings at the district level may then be selected to compete in the Ohio Academy of Science's State Science Fair at The Ohio State University on May 11, 2020.

Preserves & Natural Areas

We manage five environmental preserves that support undergraduate and faculty research and habitat conservation. The Preserve Manager Is Dr. Richard Stoffer. Students may become involved in studies of the biological and physical attributes and processes that characterize these preserves. Each preserve contains unique habitat and wildlife and thus offers a variety of study opportunities.

Other Parks and Preserves in the Area

Rock and Ohio Flora Garden

The AU Rock and Ohio Flora Garden is located next to the SW entrance to the Kettering Science Center Building.  It includes examples of many rock types, as well as examples of native Ohio plants that work well as garden and landscaping plants.  The garden was made possible in 2007 by a donation from Dr. Elizabeth Richmond in memory of Samuel I. Richmond, whose efforts helped secure funding for the original Kettering Science Center building.

Toxicology student presents research on Pesticide Analysis

Cillian Donahue, a senior Toxicology and Biology major (with a concentration in Forensic Biology) from Strongsville, had the opportunity to present her research on “Using Passive Sampling as a Method for Pesticide Analysis” at the recent National Collegiate Honors Council Conference in New Orleans. Cillian has been investigating a new method using silicone tubing to absorb pesticides from sediment for her Honors Capstone project. She is supervised by Dr. Jeff Weidenhamer (Chemistry) and Dr. Andrew Trimble (Toxicology).
Cillian writes that the feedback she received will be useful for other presentations of her research in the coming year, and that she was able to see projects that that Honors Students around the country are working on. While in New Orleans, Cillian had the opportunity to check out a couple of museums related to her scientific interests – the New Orleans Pharmacy Museum and the New Orleans Museum of Death, which has memorabilia related to famous crimes among other forensic-related topics. 
The New Orleans Pharmacy Museum (photos below) was located in a pharmacy that was founded in the 1800s. The building housed old pharmaceutical equipment and various questionable medications. Tinctures ranged from mixtures of cocaine and red wine, to heroin and sodas. In addition, there was no shortage of heavy metals, including lead coated pills for the rich, and lead baby bottles to sooth young ones. Overall, Cillian found the museum was very educational and interesting, particularly for Toxicology majors.

A Summer of Mammoths


Over the summer, Dr. Nigel Brush, Professor of Geology, has been kept busy identifying various rocks, fossils, and human artifacts exposed by recent heavy rains and flash floods here in NE Ohio. While this summer’s heavy rains were not good for farmers, as well as some home owners living near streams, it was a windfall for geologists and archaeologists as nature accidentally revealed some of the ancient treasures buried beneath the earth’s surface.

Mammoth tooth found at the Inn at Honey RunThe fossil that has generated the greatest interest was a mammoth tooth found by a twelve-year-old boy in a stream bed near the Inn at Honey Run, located a few miles outside the town of Millersburg in Holmes County. Nigel confirmed that this large tooth was indeed a mammoth tooth. He and Jeff Dilyard (a member of the Ashland/Wooster/Columbus Archaeological and Geologic Consortium) subsequently visited the Inn to examine the tooth and the find location. With permission from the Inn owner, Jason Niles, they surveyed the stream bed and banks upstream from the find site, but found no additional mammoth teeth or bones.
Two types of mammoth lived in Ohio during the Ice Age: Woolly Mammoth and Jefferson Mammoth. These mammoths had four large teeth (two upper and two lower). As the ridges on each tooth wore down by grinding grasses and small seeds, the tooth was shoved forward in the jaw by a new tooth until the old tooth fell out. Over their lifetime of 60-80 years, a mammoth would have six complete sets of teeth. Therefore, a single mammoth might lose some 20 teeth before developing its final set of teeth.
Another member of the elephant family that lived in Ohio during the Ice Age was the American Mastodon. Mastodons were slightly smaller than...Read more
