In 1993, a modification of the Master Gardener volunteer program was created to focus on ecological principles for environmentally sound gardening. The new program is called the Master Gardener-Environmental and Community Stewardship (MGECS) program and addresses important environmental concerns in Middlesex County, N.J. Program participants receive more than 100 hours of training in horticultural and ecological principles and are required to share their knowledge with others through volunteer activities monitored by cooperative extension staff. Volunteers encourage home comporting, recycling of grass clippings, proper fertilization techniques, and least-toxic pest control in the home landscape and garden. Trained volunteers have helped more than 16,000 people during the past 2 years through lectures, demonstrations, telephone contacts, and newspaper articles. Since the MGECS program began in 1993, the number of volunteer hours per person during the first year has increased by 30% compared to the traditional Master Gardener program offered from 1989 to 1992. This new program is an effective model to encourage practical environmental stewardship through community volunteer action.

As forests, agricultural fields, and suburban and urban lands are replaced with impervious surfaces resulting from development, the necessity to recover green space is becoming increasingly critical to maintain environmental quality. Vegetated or green roofs are one potential remedy for this problem. Establishing plant material on rooftops provides numerous ecological and economic benefits, including stormwater management, energy conservation, mitigation of the urban heat island effect, and increased longevity of roofing membranes, as well as providing a more aesthetically pleasing environment in which to work and live. Furthermore, the construction and maintenance of green roofs provide business opportunities for nurseries, landscape contractors, irrigation specialists, and other green industry members while addressing the issues of environmental stewardship. This paper is a review of current knowledge regarding the benefits of green roofs, plant selection and culture, and barriers to their acceptance in the United States. Because of building weight restrictions and costs, shallow-substrate extensive roofs are much more common than deeper intensive roofs. Therefore, the focus of this review is primarily on extensive green roofs.
