Now Playing at the Virtual Summit 2015: “Pollinators on the Parapets” by Angie Durhman

on May 7, 2015 at 2:43 pm under

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‘s Greenroofs & Walls of the World Virtual Summit 2015 ~ Connecting the Planet with Living Architecture: People, Projects & Design, running through May 31st.


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.


Today we are spotlighting the individual presentation “Pollinators on the Parapets” by the very personable Angie Durhman, GRP, a real go-getter from AD Greenroof and previously Tecta America.  We’ve actually known for many years, while she was still a master’s student in horticulture at Michigan State where she studied green roof plant performance and environmental sustainability.


Angie wrote a September 2004 Guest Feature article about her research on – you can see it in archives here: Encompassing the Whole Program: Michigan State University.


Angie has been at the forefront of greenroof implementation and design for years now, and has been an excellent model for female leadership in our field, especially from the “dark arts” side of roofing (funny, since her degree is in horticulture – that’s how well-rounded she is!).  She has numerous greenroof projects from across the U.S. under her belt, and she is a true team player.


Minneapolis, MN, USA. “Angie Durhman runs an exclusive green roof consulting firm based in Minneapolis, AD Greenroof. They focus on design assistance, contractor oversight, and promoting GREENFORMATION(R), a customized maintenance program for existing green roofs. In the course of her 13 years in the industry, Angie has been involved in over 400 projects of all sizes across the country. She received the GRP designation in 2009 and is often sought to present on sustainability topics to a variety of audiences. ~ Read her complete bio here from the VS2015.


You will benefit from these 5 Key Learning Objectives as Angie Durhman shares on the subject:

1) Definition of pollinators (honeybees, butterflies, native bees, among others) and problems they have been facing over the last few years (such as pathogens, pesticides including neonicotinoids, loss of habitat and more); discussions on a wide range of research; irrigation;

2) Pollinator needs are identified and just a few are nesting sites, clean water sources, and pollinator sources; native bee flight categories; expanding corridors;

3) Evaluation of desired plant species, native as opposed to cultivated, and cultivars’ morphology; a large selection of specific plants are cited; texture; source from neonicotinoid-free nurseries;

4) How to design greenroofs to encourage pollinators on the roof; asking for more structural dead load capacity early on to accommodate greater growing media depths; discussion on the importance of maintenance plans; ask for a greater design palette than just succulents; 

5) In-depth case study: Over 2 acres of semi-intensive greenroofs on 2 areas on a building outside of Omaha, Nebraska in an agricultural community; roof plan; build up of material layers; bermed areas; had 70 lbs of dead load to play with; tight construction schedule; seeded (coverage for long & short term) and hand strewn sedum cuttings, plugs, natives, forbs and grasses; irrigation system; bees are loving the blazing star, and Monarch larvae are eating the milkweed; weed issues and discussion; maintenance.
