DESCRIPTION
You Can't Always Get What You Want: Seeking, and Achieving, Urban Forest Species Diversity Nancy Buley, J. Frank Schmidt & Sons | Matthew Stephens, New York City Parks and Recreation | Elizabeth Elbel, Friends of Trees About: Identifying and procuring a healthy and diverse mix of urban adapted trees is a challenge for cities of all sizes. Discover how Oregon's Friends of Trees forecasts planting needs and partners with local growers to achieve species diversity. Learn how New York City has raised tree diversity standards by developing collaborative, multi-year procurement relationships with nurseries. Goals include providing long term species diversity modeling while challenging the status quo of 10-20-30 species diversity goals.TRANSCRIPT
You Can’t Always Get What You Want:Seeking and Achieving Urban Forest Species Diversity
It takes a decade or more for a tree to make its way from propagation,growing to landscape-ready size, to planting in your local neighborhoods.Here – five years from tissue culture plantlet to three-year bare root tree.
Two more years in an upstate New York nursery before planting in the Old City neighborhood of Philadelphia.
Time, time, time – not on our side.
Nancy’s points• It takes a decade or more to nurture a tree from propagation to landscape-ready size
• Tree supply is changing quickly from yesterday’s glut to tomorrow’s severe shortages.
• In the recession’s wake, growers can no longer produce trees on speculation. Growing unusual varieties is more risky than ever.
• How can propagators know what you will buy, 10 years down the road? How do YOU know what you will need?
• In the future, getting what you want will require planning, open communication and creative growing agreements with trusted nursery partners.
• Visit nurseries, understand tree production timelines, communicate!
