Join us for our regular Wednesday and Saturday volunteer events and become a steward of our beloved natural area Forest Park!! Volunteers will take a short hike to one of our various sites and work off-trail removing ivy, planting native plants and occasional trail work. This is a DIRTY job so come prepared in grubby, long-sleeved clothing and boots. We'll provide gloves and tools.

  • Groups of five or more persons need to call 503-823-9423 to register at least a few days in advance.
  • Groups of 10 or more should call 503-823-9423 at least one week ahead.
  • All ages are welcome to attend; young children must be supervised by an adult.
