When autumn arrives, beech and oak trees do not completely form the layer that permits a leaf to separate and fall from the branch. If the leaf doesn’t fall, new leaves in the spring will push them off
The scoring system for national and state champion trees was based on measurements of the tree’s circumference, height and average crown spread. Circumference is taken 4 and one half feet above the ground.
Black walnut trees are among the last trees to leaf out in the spring and among the first to lose leaves in the fall.

Christmas tree growers tout their trees as a renewable resource that is entirely biodegradable. Firs are very popular for cut trees. Despite its name, Douglas fir is not technically a fir but rather is classified botanically in a separate genus from true firs. The fragrant tree bears soft short needles. A relative newcomer is a true fir called Canaan fir. It is attractive to consumers who are drawn to its soft needles, fresh fragrance and bright color.
Mistletoe is a parasitic plant and grows on hardwood trees. It puts down roots right into the tree bark, drawing water and nutrients from its host. While host trees gain nothing from the partnership, they are rarely harmed by the mistletoe’s existence. Eastern wild mistletoe is common along the Ohio River from Marietta to Cincinnati. In fact, southern Ohio is on the northernmost edge of the mistletoe range.
It takes cold nights and warm days to make the sap rise in sugar maple trees. An average of 40 gallons of sap will produce one gallon of syrup. Two modern advances in the sugar bush include plastic collecting tubes with a vacuum and reverse osmosis to remove water before boiling.
In the latest survey of Ohio’s forests it was determined that Ohio has 7.8 million acres of forestland. This equals approximately 30% of the state. Since the 1991 survey, there has been an increase of 100,000 of forestland.
The National Woodland Owners survey determined that Ohio has approximately 336,000 family forest owners and that 93% of those owners hold fewer than 50 acres.
The Ohio Department of Agriculture is surveying Crawford County for the infestation by the emerald ash borer. Our county is in the High Risk survey area. The sampling traps are made of corrugated plastic and have three sides. The key identifier will be its purple color. The traps pose no risk to humans, domestic pets or wildlife.
