24 Years of Tree Growth in Westminster, Colorado

The Colorado State Forest Service, along with City of Westminster Forestry Staff, recently remeasured trees as part of a 24-year diameter growth rate study and updated the report initially published in 2000. The report characterized the long-term growth of 19 common urban tree species grown on publicly maintained land in Westminster for 1992-2016. The average trunk-diameter growth rates of the nearly 1,500 studied trees can be used by homeowners, landscape architects, designers/installers and tree care professionals to select trees for planting that will most quickly provide shade, aesthetics and other benefits after planting.

 

Keith Wood graduated with a degree in Forest Biology from Colorado State University in 1986 and went on to study aspen ecology on the West Slope of Colorado, receiving his Master's degree in 1988.

Lecture - Mid-century Garden Design for the Modern Home

In her recently published book, “Mid-century Modern Landscape,” author Ethne Clarke offers a fresh guide for those seeking bold approaches to redefine their outdoor space or wishing to learn more about the history of mid-century modern aesthetics. During this lecture, she explores the origins of residential mid-century modern garden design for the home, revealing how designers blurred the divisions between indoors and outdoors, thus creating gardens that were for living, a style that went on to inspire contemporary gardens around the world.

 

Ethne Clarke is an award-winning journalist, former garden editor of Traditional Home and contributing editor for House & Garden. Well-known as the author of a number of best-selling books on practical gardening, design and landscape history, she holds a Master of Philosophy from the faculty of Fine Art, De Montfort University, England. Her research has involved a close study of architectural history between the Arts and Crafts period and early Modernism, and this has been a guiding influence on the renovation of her house and garden in Colorado Springs—a small mid-century modern ranch built in 1958.
