Now Playing at the Virtual Summit 2015: “Using a Climate and Ecological Template Approach for Plant Selection for Extensive Green Roofs” by Ed Snodgrass

May 21, 2015 at 2:17 pm

In celebration of honoring Earth Day 2015 and our planet’s ecology through healthy, regenerative design, we are highlighting each of the 23 awesome videos from our 30+ spectacular speakers from Greenroofs.com‘s Greenroofs & Walls of the World Virtual Summit 2015 ~ Connecting the Planet with Living Architecture: People, Projects & Design, running through May 31st.

VS2015-OnDemand-Website

Our hope is that by familiarizing you more with each presentation and its particular benefits, you will be enticed to join us during our wonderfully easy-to-navigate online Virtual Summit!  And, along with the speakers’ input, I will identify 5 Key Learning Objectives or “takeaway” bullet points that each video presentation provides to participants.

VS2015-EdSnodgrass

Today we are spotlighting the individual “Using a Climate and Ecological Template Approach for Plant Selection for Extensive Green Roofs” by the wonderful Ed Snodgrass, quintessential plantsman and co-owner of Emory Knoll Farms/Green Roof Plants, responsible for supplying 7,618,400 square feet of greenroof plants (and counting!).

Ed has collaborated on many excellent books, which you can all all find in our Bookstore by the way, and we’ve known him from way back – since 2002.  He was one of our keynote speakers from our inaugural Virtual Summit 2011, and you can see his video “Right Plant, Right Place” Opening Keynote Address by Ed Snodgrass on our YouTube channel here.

VS2015-EdSnodgrass1

Ed has also been a contributing editor on Greenroofs.com since 2004 as the Plant Editor where he answers reader questions, writes very occasional articles, and features seasonal greenroof plants in “Ask Ed.”  But with all of his traveling lately, we certainly can’t criticize him too much – plus we love him dearly anyways.

You can read my 2009 “From Llamas to Greenroofs: An Interview with Ed Snodgrass” to get a glance into his life.  He’s so amiable and knowledgeable it seems like most everyone in our industry knows him!

VS2015-EdSnodgrass2

Ed says “This talk will focus on plant selection using climate types for selection, understanding the difference between a continental and maritime climate, for example, and what that means for plant survival and maintenance.  This talk will also look at plant selection and the promise of the delivery of ecosystem services such as habitat creation or biodiversity.”

Snodgrass is president and founder of Emory Knoll Farms, Inc. and Green Roof Plants, North America’s first nursery specializing in green roof plants and horticultural consulting. Edmund has consulted on projects throughout the US and also in England, France, New Zealand, China, Australia and Morocco. Since its inception, Emory Knoll Farms has supplied plants for over 1000 green roof projects.

You will benefit from these 5 Key Learning Objectives as Ed Snodgrass shares on the subject:

1) Plant selection relative to the function of the plants and the geography of the roof location.  What do we want from them, what are we asking these plants to do, and what are we asking them not to do on the harsh locations of rooftops;

2) Use not only the USDA Plant Heat Zone and Hardiness Maps but also the World Maps of Köppen-Geiger Climate Classification as they give much more data regarding rainfall and the Grimes Triangle showing the 3 ecological strategies of plants by type: Ruderals, or pioneers, which are disturbance-tolerators; Competitors, which are long term winners; and the Stress-tolerators which can live where nothing else can; 

3) Habitat examples with these attributes to visit: the alvar plains in upstate New York, Huntington Botanical Gardens in CA, pioneer thermophyllic herbaceous communities on rock outcroppings in central Europe, Lava Beds National Park in CA;

4) Plants develop different strategies depending on where they live, e.g. removal of chlorophyll, live during the good times only, size; see what’s growing on naturally occurring roofs in urban areas – examples from Morocco and China; developing cultivars for greenroofs selected especially for a particular stress;

5) How do we want plants to perform?  For example as larval sources, urban beekeeping, stormwater management, highly evapotranspirative, amelioration of atmospheric deposition.  A look at two distinct greenroofs at the University of Melbourne.  Plant specification has gone from really thinking about it to being very casual, so it’s time to reenergize some of our scrutiny.

The 2013 Nanjing World Green Roof Congress was successfully held in the Purple Palace from September 15th to the 17th.

Nanjing2013Opening

The event was sponsored by the China Association of Building Energy Efficiency, Nanjing Municipal People’s Government, China Green Building Council of Chinese Society for Urban Studies, Department of Housing and Urban-Rural Development of Jiangsu Province, World Green Infrastructure Network and the International Rooftop Landscaping Association (IRLA).

The group pictures above are of the smog in Beijing this past June.  We can see clearly there are 18 days of haze in merely a month, which brought Beijing to the top 10 cities with the worst air quality in China.  In fact, it’s not only Beijing that is in this situation, but many other cities in China are suffering from this severe pollution as well.  As the air quality and environmental pollution are getting worse and worse, the Chinese government has also realized that it’s time we should do our best to restore fresh air, clear water and vigorous nature, which contributed to the theme of the Nanjing Congress: vertical greening dispelling haze, conservation culture beautifying cities and towns.

During the congress, we visited several outstanding greening projects in Nanjing, all of which expouse advanced ideas and technologies.  For example, all buildings in the Zidong International Creative Park, the cooperator of the congress, have attained the standard of national green building, and all of the buildings have green roofs.

PhoenixValleyChina

“Phoenix Valley” boasts mobile remote controlling for all of its rooftops offering precise irrigation solutions.

HexiNewEcocity

A little different from Phoenix Valley, here you can see “Hexi New Ecocity,” with the idea and realization of the new ecocity as green architecture and smart city, along with vertical greening.

Tree Cube

Among all the projects, the most creative one should be the “Tree Cube” in Changzhou, because the buildings have made micro circulation and zero garbage discharge come true.

TreeCube4

These projects are just typical representatives of green architecture in China.  Through this Congress, Chinese designers and people who are enthusiastic in greening can exchange ideas with experts all over the world, and also learn experience from them, thus enabling more people to construct more green projects like these.

With this goal, and to facilitate the communication among designers from different countries, the award ceremony of the Green Award International Landscape Planning Competition* was held simultaneously with the 2013 Nanjing World Green Roof Congress.  Academician Zhaozhen Meng, left below, attended the ceremony as award presenter.

Nanjing2013Audience

The Sino-Singapore Green Land Property Forum, Sino-Japan Hanging Garden Forum and forums about new materials and technologies pointed out bright ways for relevant Chinese workers in our industry.  After the three-day congress, many attendees told the council they felt fruitful and willing to learn more about how to practice the theories.  They also expressed their anticipation of the 2014 Qingdao World Green Roof Conference.

QingdaoWGRC2014

With all these magnificent achievements from the 2013 Nanjing Congress this time, we believe that in the future, more classic projects will spring up, and our greening industry will prosper in every corner of the world.

We invite you to participate in the 2014 Qingdao World Green Roof Conference!
