*High Flood Tolerance: Generally lowland wet species surviving when flooded or exposed to

high water table more than 40% of the growing season.

*Moderate Flood Tolerance: Generally lowland wet species surviving when flooded or exposed to high water table more than 30% of the growing season but less than 40%.

*Intermediate Flood Tolerance: Generally lowland wet-mesic species surviving occasional

inundation or elevated water table between 20% and 30% of the growing season.

*Low Flood Tolerance: Generally upland mesic and mesic-dry species rarely inundated or

exposed to an elevated water table for periods of short duration, between 5% and 20% of the

growing season.

*No Flood Tolerance: Generally upland dry species exhibiting immediate and rapid decline

frequently culminating in death if inundated or exposed to elevated water table for more than 5% of the growing season.

**Shade Tolerance: Shade tolerance means able to grow in a state of health and vigor beneath

dense shade. In this ranking, shrubs and vines are ranked on a scale of 1 to 5, with 1 being very shade tolerant, and 5 being very shade intolerant.

Note:

1.   The majority of plants listed are available on the local commercial market and do not displacenative species.

2.    The cultivated varieties (“cultivars”) of the species listed above may also be used.

Best Native Ohio Trees

Standing Strong: Some tree species adapt better to environmental change and disturbance than others. These adaptable trees resist pests and diseases or tolerate changes in shade levels, drought and storm systems. Climate change models project the following species will thrive in Northeast Ohio over the next several decades:

 

	Height at maturity	Spread at maturity	Growth/year
Butternut Hickory	80’to100’	60’ to 80’	18” to 24”
Black Oak	70’ to 90”	70’ to 90’	14” to 18”
Black Walnut	70’ to 90’	70’ to 90’	18” to 24”
Bur Oak	70’ to 80’	70’ to 80’	14” to 18”
Eastern RedCedar	40’ to 55’	10’ to 25’	9” to 12”
Scarlet Oak	70’ to 90’	70’ to 90’	16” to 20”

 

Recently Adaptive Trees
American Sweetgum	60’ to 85’	40’ to 50’	18” to 24”
Blackjack Oak	35’ to 50’	35’ to 60’	7” to 10”
Chinkapin Oak	70’ to 90’	70’ to 90’	16” to 20”
