Green Roof Styles
Extensive
Intensive
Semi-Intensive
Green Roof Styles Extensive Green Roofs
Media less than 15 cm
Primarily a groundcover of hardy xeric plants
Require no watering after plants establish
Green Roof Styles Intensive Green Roofs
Media exceeding 15 cm
Herbaceous and large scale trees and shrubs
Maintenance may include irrigation during extreme dry periods.
Green Roof Styles Semi-Intensive Green Roofs
A blend of both systems
Varying media depths and plants
Benefits of Green Roofs
Storm Water Retention and Mitigation
Cooling Effect on The Urban Heat Island
Habitats for Animal Species
Carbon Sequestration
Increased Green Space and Aesthetics
The Green Roof Environment
Extreme Irradiation and Heat
Prolonged Wind Exposure
Infrequent/Volatile Rainfall Events
Limited Soil with Frequent Freeze/Thaw Cycles
Pollution
Research Project
Establishment and Survivability of Seaside Goldenrod in LiveRoof® Modular Systems
Two Main Goals
Research Project
Which Autumn Planting Time is Optimum for Establishment
Can Seaside Golden Rod Survive In the Liveroof® Liveroof Modules Over Winter
Methods
Three Planting Times-54 plants 9 Modules
September, October, November
50% Sampled in December
Weight Comparison
Liveroof® Liveroof Modules and Media
Modules are 30.5 cm x 61 cm x 7.6 cm
100% Recycled Polypropylene
100 mm Thick
Liveroof® Liveroof Modules and Media
LiveRoof® Media Trade Marked Blend
Expanded Clay
Fine/Coarse Sand Mix
Organic Matter
Methods
Modules will Experience Winter Conditions
Modules will be Greenhouse Forced in Late February
Survivability Evaluation
Seaside Goldenrod Solidago sempervirens L. Plant Description and Habitat
Indigenous to the Atlantic Region Leaves are Lanceolate and Fleshy Golden Inflorescences in Terminal Panicles Herbaceous with a Vigorous Rhizome Frequents Coastlines, Roadsides and Dunes Classified as a Halophyte with Xeric Qualities
Summary Relevance of Seaside Goldenrod in this Experiment
No Current Evaluation of Seaside Goldenrod in Liveroof ® Modules Exists
Successful in Marine, Dry and Nutrient Deficient Habitats
Late Season Pollen Source for Indigenous Fauna
