Millions of years ago, Ohio’s landscape looked much different than it does today. A warm shallow ocean covered the land and strange creatures inhabited these waters. These creatures, including filter feeders, a few scavengers, and even predators, all roamed the ocean during the Ordovician time period, which was over 450 million years ago. Over time these warm shallow oceans were replaced by mountains and forests as Ohio’s land moved north of the equator. The Cincinnati area is known for having the most Ordovician fossils. This was due to an uplift that happened in the Earth’s crust, which caused a special feature called the Cincinnati Arch. This lift allowed many of the fossils normally found deep within the layers of the earth to push upward to the surface so that we can find them. Now, you can find clues to the ancient past by looking at the limestone and shale rocks in the Cincinnati area.

These ancient fossils are the remains of past life. In Ohio, fossils are everywhere. They are found in all 88 counties of the state. The fossils found in Ohio are special because amazingingly enough, they are OLDER than the dinosaurs! Fossils are useful to us in many ways. They are evidence of animals of the long-distant past, they show the appearance of different life forms and they are the documents from which development of life in the past can be traced. Scientists from all over the world travel to the Cincinnati area to view these special fossils.

One example of a fossil you can find in Ohio is the trilobite. Trilobites are one of the earliest forms of the group arthropods. The name trilobite means “three-lobed”, based on their body plan. Trilobites were predators on the ocean floor and they came in many different sizes and shapes. Some can be so small you need a microscope to see them and some can be up to two feet across. In Ohio, our state fossil, Isotelus Maximus, is a trilobite and is one of the largest species we find. Many times when we find them, they are rolled up in a ball, meaning they had used their hard exoskeleton for protection. There were many species of trilobite, but all are now extinct. However, a close relative of the trilobite is a horseshoe crab. If you are looking to find a trilobite, look in the layers of shale rock where you are more likely to find an unbroken, whole fossil.

Take some time to explore and see if you can find a fossil treasure. Take time to think about what the animal may have looked like or how it may have moved and hunted for food. Challenge yourself to find the smallest individual fossil or try to find a rock with the most fossils embedded in it. Use our fossil guide to look for all the different types of fossils we have here in Ohio or try the Greenacres ‘Ordovician Sea Floor’ Coloring Page. Take time to learn what is under your feet as you explore the fossils of Ohio. Happy fossil hunting!

When most people visit forests, they tend to look mostly upwards, into the trees looking for birds and squirrels, or off in the distance hoping to glimpse a deer or coyote. But if you want to have the best chance of seeing a lot of animals, you should look down. The forest floor habitat teems with small interesting animals that are easy to find and observe.

When you visit a natural place, you are in a habitat. A habitat is a place where an animal or plant lives and gets all the things it needs to survive and reproduce (food, water, shelter, and space). Habitats can be very big or very small. A bald eagle’s habitat would be thousands of acres in size and might contain several lakes and rivers, and many patches of forest and field. A spider’s habitat might be a single plant where it builds its web and spends its entire life. Larger habitats contain many ever-smaller habitats, nested within the larger ones like Russian dolls.

Very small habitats are called microhabitats. Two very different microhabitats can be within a very short distance of each other, and they are distinct because they have different characteristics such as moisture, temperature, or soil type.

The food of the forest floor habitat is provided largely from above. Trees make food all summer and then drop it in the fall. Outside of the annual leaf-fall, trees drop branches, leaves, fruits, and even whole trunks during other parts of the year. This tree “debris” (as we might think of it) is the energy that keeps the forest floor ecosystem going. Leaves are the main food of the forest floor, and branches, logs and soil also provide a lot of shelter.

One way to uncover the secrets of the forest floor is to roll logs, or move rocks or pieces of bark and see what is underneath. Always remember that as a visitor to the forest, you have a responsibility to be non-destructive. Most parks require that visitors stay on trails because if everyone rolled logs constantly, the habitat would soon be damaged. So if you do this, make sure you are allowed, and do it in moderation. When you overturn a log or rock, always carefully place it back just as you find it to preserve the qualities that made it a good place for something to live. And if you do find something living under there, be careful not to drop the log back onto it. Finally, don’t turn logs in cold weather, as you will cause animals that are seeking warmth to freeze to death. One way to expand your searching opportunities is to add habitats to your own backyard natural area by putting down plywood or sheet metal pieces (or logs, of course). These can later be searched, and you will see that animals will move in quite quickly.

When you move a log, notice that the microhabitat characteristics under the log make it a unique place. When it is very dry near the log, it will be moist under the log. If it is hot out, you’ll notice that it is much cooler under the log. Often, there are no leaves, which makes the soil accessible to the animals. If the log is decayed, there are hundreds of little hiding places. You will often see the white thread-like hyphae of a fungus. Fungi are decomposers, so they break down things like logs, releasing the nutrients back to the soil. As they break down the log, the log becomes food, and so do the fungi. Another great benefit to living under a log is protection from predators. If a small snake is living under a log, it is safe from bird predators (a bird can’t roll a log like you can).

So what are some common animals that you might find under a log? Or, put another way, what members of the forest floor community might use a log as their microhabitat?

Greenacres is the place to be – be green that is! Being green is one of our 4 values that help guide our mission. We strive to recycle the best we can, and that means taking extra steps to ensure we are reducing as much waste as possible. Here are our top five tips for being green.

Tip #1: Educate yourself! You cannot recycle correctly if you don’t know what can and cannot be recycled. Learn what your local municipality (Rumpke-Cincinnati, OH) accepts for curbside recycling. There are 5 categories of curbside recycling: paper & cardboard, glass, metals, cartons, and plastics. You can always check out Rumpke’s website for more information. They even offer free tours of the Material Recovery Facility (MRF), which can help you gain a better understanding of why they collect what they do and where these things ultimately end up. Ask questions! Find some good resources that you can ask questions to get specific answers. Feel free to email us at lnichols@green-acres.org to get some answers.

Tip #2: Start composting! According to a Hamilton County Solid Waste Composition Study (2018), 14.9% of landfill waste is food waste. Some of the food waste are food scraps that could be composted and turned into usable soil, instead of sent to the landfill. In addition to food waste, the study also showed there was another 16.9% of landfill waste that was yard waste, which also could have been composted! Looks like it’s time to start your own compost bin in your backyard. If you don’t want to start a backyard bin you can look into a compost service. There are several composting services in the Cincinnati area, including Go Zero, which lets you drop off compost to a station!

Tip #3: Reduce your overall consumption! How would you like to help the earth and save money? Try doing a spending freeze for a month. Limit yourself to only buying necessities such as food, transportation, and bills. You’ll quickly notice that you buy many things that you did not really need and can survive without. For example, maybe try buying a reusable water bottle (which is a one-time purchase) instead of a case of water each month. You might even become creative and start reusing things that you wouldn’t normally reuse. An old cardboard box is now a kid’s fort! Those old takeout containers are now what you can pack a lunch in. You’ll be surprised how much waste you reduce. You’ll not only have a fatter wallet at the end of the month, but a better appreciation for what you already have. And when you do buy, try to buy local. Hint, hint: the Greenacres Farm Store is a great place to get fresh produce!

Tip #4: Remember that this takes time! You will not be able to make all these changes overnight. Being green can be challenging to start. If you use a plastic straw one day, don’t kick yourself over it. Just try again next time. We can’t always plan for everything that life throws at us, and sometimes convenience of single use plastics gets in the way-and THAT’S OKAY! Just remember that you are trying, and will get better with practice and effort.

Tip #5: Look for other recycling avenues! There are several organizations out there who love to recycle as much as you. If your general curbside recycling (see Tip #1) won’t take it, you might still be able to reduce your landfill footprint with a little extra effort. See below for a handy list of common items.

I know some of this information can be a little overwhelming. Don’t you just wish you could drop off all of your non-curbside recycling without multiple stops and with minimal effort? You can! Each year in Washington Park, Keep Cincinnati Beautiful hosts a One Stop Drop event where all of these items and more (that are not normally processed in your curbside bin) can be dropped off! Be sure to check their calendar to see when the next one is.
