Our urban forests are under siege from disease, aging canopy, budget constraints and more. Leading experts on creating a vibrant urban canopy from across America will launch this first event of its kind in Colorado.

The Speakers:


“Tough Trees for Urban Landscapes”


Guy Sternberg owns Starhill Forest Arboretum in Petersburg, Illinois. Guy retired after a long career with the Illinois Dept. of Natural Resources and is a life member of the International Society of Arboriculture as well as a landscape architect. He was also a founding member of the International Oak Society. He has written two books on native American trees (Timber Press), and has introduced many new tree cultivars.

 Steve Bieberich

 “Trees For Hot Dry Places”


Steve Bieberich owns Sunshine Nursery in Clinton, Oklahoma. He’s developed numerous trees that thrive in the dry climate and alkaline soils of western Oklahoma. He has collected in Asia and across America,  grown and evaluated in his nursery-arboretum. He was the first to introduce the thornless male Osage orange cultivar ‘Whiteshield.’ He’s a world authority on cultivated Ulmaceae.


 Tree Selection & Propagation”

Scott Skogerboe is the head propagator at Ft. Collins Wholesale Nursery, growing over 300,000 plants a year. Scott, a Ft. Collins native and CSU graduate in landscape horticulture, has spent decades in exploring, selecting and propagating trees and shrubs that are adaptable to climate and soil conditions in communities stretching from Casper, WY to Albuquerque, NM.


 “Citizen Activism to Revitalize anUrban Tree Canopy”

Mike Hayman lives in Seneca Gardens, Kentucky. He was a professional newspaper photographer who undertook a major tree planting and diversification program near Louisville after a freak windstorm devastated a mature but non-diverse tree canopy twenty years ago. His efforts, now codified in city policy, were among the first to mobilize major citizen support of species diversity and Seneca Gardens is now viewed as a mini-arboretum.
