Historic filbert orchards at Dorris Ranch soon may be treated for pests and disease with organic practices instead of commercial-grade pesticides on the recommendation of a committee formed to help the park's operator make visitors and nearby residents safer.

Willamalane Parks and Recreation District, which runs the historic park, established the committee after some community members this summer raised concerns with the Willamalane board about the pesticides used to sustain the commercial filbert orchards there.
