SPRINGFIELD, Mass.- Sustaining the Living Landscape: The 21st Annual ELA Conference & Eco-Marketplace, is scheduled for Feb 25-26, 2015 at the MassMutual Center.

The 2015 conference program offers many well-known speakers who are experts in their fields. Topics include: plant response to climate and land use changes, designing with rating systems (SITES, LEED and Living Building Challenge), exploring new fertilizer regu­lations, innovative stormwater management and much more.

The keynote speaker, scheduled for Wednesday, Feb. 25, will be Rick Darke, titled “The Essential Layers of Living Landscapes”. The richness of life in any landscape is linked to the diversity in its layers, and this is true for both people and wildlife.

At the ELA Conference Keynote Dinner, Darke will look at layers from ground cover to canopy and will describe and illustrate how to conserve, create and manage them in landscapes that are beautiful, biologically diverse, and joyfully livable. Using examples from a wide range of public and private projects, he will present a practical, ecologically sound approach to layering that he calls spacemaking with organic architecture.
