Seeding Green Roofs With Native Grasses, Richard K. Sutton

Landscape Architecture Program: Faculty Scholarly and Creative Activity

During six years of native grass establishment and growth on four green roofs, we sought to understand appropriate seeding seasons and spacing, the amount of time to reach the industry 80% coverage threshold (FLL 2008), the seed yield projections for volunteer plant infill. We also produced and tested methods for successfully and inexpensively seeding and determined “as needed” irrigation protocols. The suite of techniques examined improves and enhances the use, establishment, and management of native grasses on green roofs and reduces green roof costs.

Rethinking Extensive Green Roofs To Lessen Emphasis On Above-Ground Biomass, Richard K. Sutton

Landscape Architecture Program: Faculty Scholarly and Creative Activity

In the future, most green roof applications will not be highly visible, yet these roofs will still provide the benefits of heat island reduction, stormwater control and biodiversity for hard-surfaced cities. However, human bias in wanting more biomass and visible blooms leads green roof horticulturalists and their approach of maximizing those aspects down a slippery slope that, in turn, leads to increased hours of labor, over-watering and fertilizing and specifying too many cultivars

Ecology Of Scale In Visual Landscape Assessments, Richard K. Sutton

Landscape Architecture Program: Faculty Scholarly and Creative Activity

Background readings on scale plus twenty-three visual landscape assessment studies from 1968 to 2006 were examined to understand the nature and use of scale and its relationship to the visual environment. The objectives of this study were to: 1) describe the concept of scale as applied to visual assessments, 2) review scale use in selected visual assessments, and 3) identify issues that need further research to better integrate scale into visual landscape assessments and landscape ecological theory.

Basic concepts and features relating observers with landscape and scale required defining scale, bounding visibility, perceiving scale, seeing hierarchically, and visualizing grain and …
