The Park District partnered with the West Suburban Openlands Treekeepers and the Morton Arboretum to save hundreds of 200- to 300- year old oak trees as part of the Heritage Oak Propagation Program. Grown from acorns back in 2008, a total of 51 of these living treasures were planted in 2015 in Scoville, Mills, Taylor and Field Parks. The nurturing and planting of these trees enhances biodiversity and is part of the District’s broader strategy to use natives whenever possible to best support our environment.
