Living Landscape Function Calculator


           In order to support this effort, Sohnly started a 501(c)3 nonprofit entity, Environmental Metrics Unlimited (EMU), in October 2017, in association with The Urban Affairs Coalition in Philadelphia. Environmental Metrics Unlimited, known as EMU, is a collaboration between Professor Douglas Tallamy, Landscape Architect Rich Darke and a team of landscape designers led by Christopher Sohnly (LA2015) and Nicole Jackson (HORT2017).

After having spent several months developing industry partnerships and creating a basic website EMU is now launching a GoFundMe campaign to fund the expansion of the website and to bring the Living Landscape Function Calculator to the web as an interactive database.

Thank you for supporting our efforts!

The current work being done on the Living Landscape Function Calculator has the potential to allow people from horticulture, environmental, educational, and landscape architectural fields to have access to an operating system for the purpose of standardizing function in the landscape.


This tool can be the foundation of assisting in the inspiration of home owners to further their interests and actions related to sustainable landscapes. We at Cavano's Perennials have enjoyed working with folks involved with this project and supporting them in this endeavor.
