Just Chill: How Cold Hardiness Works

birch trees use deep supercooling

By Brandon M. Gallagher Watson


In the upper regions of Siberia, nearly 450 miles above the Artic Circle, resides one of the world’s toughest tree species. Larix gmelinii, known as the Dahurian larch, holds the distinct title of “World’s Northernmost Tree Species.” Living in this area, just above the permafrost layer, is not for the faint of sap.  Read more>>>

Leave Wildlife in the Wild

Wildlife officials discourage handling young animals

COLUMBUS, OH – The spring season has arrived, and so too has the season for Ohioans to enjoy spotting young wildlife. Each year, Ohio Department of Natural Resources (ODNR) officials offer this simple advice, enjoy wildlife from a distance and leave young animals in the wild.Many adult wild animals will leave their young offspring alone while they forage for food, or to divert the attention of potential predators away from the more vulnerable young. When young animals are discovered with no adults in sight, the adult is often nearby waiting for people to leave the area before they retrieve their young.

Most wild animals are raised by only one adult or are not tended to during the daylight hours. In the case of white-tailed deer, a doe will hide her young from predators by leaving it alone in a secluded spot, such as a grassy meadow or a flower bed. A hidden fawn has virtually no scent and when left alone is difficult for predators to find. The doe will tend to the fawn or fawns several times each night.

It is important to leave animals in the wild. If people disturb a nest, they should replace the young animals and the nest material as close to the original location as possible. It is a myth that wildlife parents will not tend to young because of human scent.

State and federal laws protect and regulate wildlife and endangered species in Ohio. Only licensed wildlife rehabilitators, working under special permits issued by the ODNR Division of Wildlife, may possess and care for native wild animals. These laws are in place for the benefit of humans as well as wild animals.

To further protect young and vulnerable wild animals, keep pets under control so they do not raid nests and injure wild animals. Keep pets inoculated against parasites and diseases.

Check for nests before cutting down trees or clearing brush. It is best to cut trees and clear brush in the autumn when nesting season is over.

Educate children to respect wildlife and their habitat, observing wildlife from a distance.

Contact your local wildlife official before taking action. Call 1-800-WILDLIFE or visit to be connected with the proper individuals.

ODNR ensures a balance between wise use and protection of our natural resources for the benefit of all. Visit the ODNR website at

Why Hire an Arborist?

Arborists specialize in the care of individual trees. They are knowledgeable about the needs of trees and are trained and equipped to provide proper care. Hiring an arborist is a decision that should not be taken lightly. Proper tree care is an investment that can lead to substantial returns. Well cared-for
trees are attractive and can add considerable value to your property. Poorly maintained trees can be a significant liability. Pruning or removing trees, especially large trees, can be dangerous work. Tree work should be done only by those trained and equipped to work safely in trees.

Sustainable Gardening Humor

GOD: Francis, you know all about gardens and nature. What in the world is going on down there? What happened to the dandelions, violets, thistle and stuff I started eons ago? I had a perfect, no-maintenance garden plan. Those plants grow in any type of soil, withstand drought and multiply with abandon. The nectar from the long lasting blossoms attracts butterflies, honey bees and flocks of songbirds. I expected to see a vast garden of colors by now. But all I see are these green rectangles....

Annual Maple Leaf-Drop Commences


The annual leaf drop caused by MAPLE PETIOLE BORER (Caulocampus acericaulis) on sugar maples is beginning to occur in southwest Ohio.  Although sugar maples are generally preferred, this sawfly will also occasionally infest other maples.  Fortunately, while the number of fallen leaves beneath an infested tree may look dramatic, defoliation seldom exceeds levels that are considered detrimental to the overall health of the tree.  Read more>>>

Homeowner Association Tree and Resource Management

Davey Resource Group is pleased to present a website ( that contains the results and products of a project developed to educate and influence homeowners associations (HOAs) to become better stewards of trees and natural resources on their properties.

The project was funded by a National Urban and Community Forestry Advisory Council grant, developed by Davey and supported by national partners.  Leaders or managers of HOAs directly affect the quality and quantity of landscape trees, forest cover and natural resources on their property. Yet, these groups may not have the knowledge and tools needed to maintain and enhance these green assets for the benefit and safety of residents, visitors and the community at-large.

That’s why Davey and our partners created the HOA Owner’s Manual that contains educational resources that specifically address tree and natural resource management. The manual is an interactive computer program that contains practical information on managing trees and natural resources, links and tools for more information, examples of contracts and specifications, and other guides to help HOAs achieve the goal of creating livable and safe neighborhoods.

If you are an HOA leader or professional property manager, you can use this manual to:

· Spend landscape maintenance funds more efficiently

· Increase your understanding of tree benefits

· Improve tree care and planting practices on your properties

· Create new and useful partnerships between the HOA, residents, local tree experts and the community

If you are a municipal forester, extension agent, professional arborist, or natural resource expert/advocate, you can use the Manual’s companion

Leadership Guide to conduct a short workshop designed to encourage and engage HOAs in better managing their trees and natural resources.

The guide contains presentation and support materials for simple workshops intended to be led by local experts. All of these resources are free to use on the site and to copy. Please share this website and the materials found on it with others.
