They all responded and their comments are reflected in the draft of September 4, 1990. Finally, the draft was submitted to the County Counsel for review, The Task Force has had no response from the County Counsel for over three years.

This ordinance will help ensure the integrity of oak and indigenous tree communities Countywide. This ordinance is also in keeping with on-going cooperative biodiversity planning efforts of which the County and Park District are a party to. This Ordinance would indeed complement existing Park District Policy for protecting oak and other indigenous trees. As you may know, the District is responsible for several hundred thousand trees found in our parkland and natural open space areas. We take seriously, our mandate to be responsible stewards of these natural resources. In 1989 , the Park District Board adopted a functional equivalent of the proposed County Ordinance. Our " Tree Management Policy" guides the District in protecting its natural forests, as well as managing trees in designated developed public use areas. At the heart of the policy is the principle that native trees will be left in their natural condition and not managed on a tree-by-tree basis. The Policy also includes a tree removal review process to ensure that a recommendation to remove trees is 'justified and that the appropriate parties have been consulted. The District would like to express its support for this proposed ordinance to protect oak and indigenous trees and related habitat values on unincorporated private lands throughout the County. Should you have any questions or need further information, please contact Martin Vitz, Advanced Planning Manager or me at 635-0135, ext. 2600.
