II. Ohio Wildlife

• native plant: a plant that grows in the wild without human intervention

• exotic plant: also called non-indigenous, invasive; a plant that was introduced by human intervention from another area or country (accidentally or purposefully)

Bee Balm - Native Phragmites - Exotic

Why Plant Natives?• better adapted to local

environmental conditions. • of value to local wildlife. • require less maintenance. • provide four-season interest. (nectar

in flowers, seeds, fruit production essential for migratory birds)

• preserve native species and biodiversity.

• add a local accent to the landscape instead of just “grass”

Ohio’s Prairie Past Native Communities

• "prairie" is from the French "pré" which translates into English as "meadow"--a meadow and a prairie are similar in the sense that they both lack woody vegetation.

• very little of the original prairie exists due to commercial agriculture, development of communities, towns, roads, etc.

Prairie Plant Characteristics

• Prairie plants have deep roots so they are resistant to drought.

• About two-thirds of a prairie is actually underground as a dense mat of roots.

Importance of Prairies • Functional prairie/grassland areas

adjacent to stream systems are essential for erosion control and sediment management, especially in regions with limited riparian vegetation.

• control of non-point source pollution, and both groundwater and surface water systems that drain through prairie/grassland regions and can help control floods,etc.
