Worthington Arbor Advisory Committee

Arbor Committee

The Worthington Arbor Advisory Committee (WAAC) was established by Worthington City Council in 1988 to address problems associated with the redevelopment of the Village Green. Today this committee of volunteer members works closely with, and serves as, advisors to our Parks and Recreation and Service Departments.

The current eleven members serving include a Metro Park manager, several horticultural professors, a city forester, an ODNR urban forester, a landscape horticulture graduate, a park naturalist and environmental educator, a professional arborist and interested homeowners.

WAAC's mission is to enhance the quality and longevity of Worthington's public landscape with trees being the priority.

WAAC believes the urban forest is a unique asset that provides our community with a beautiful, healthy and comfortable environmental base. When we consider Worthington- its downtown, parks, street trees and public, commercial and private landscapes, we take great pride in being residents of a progressive and attractive community.

Oak Chlorosis 

Chlorosis in pin oaks is usually due to a deficiency of iron in the leaves. Iron is important for chlorophyll synthesis in plants, so when it is deficient, leaves cannot make chlorophyll, resulting in a yellow appearance. Chlorosis of pin oaks is typically associated with alkaline soil.
