The goals of this work item are to create a standard that 1) describes the criteria and procedures by which to develop an invasive plant list for a defined region and 2) will be useful as the foundation for creating lists of invasive plants to support building codes and related applications.
Model building codes and rating systems that aim to improve the environmental performance of buildings and their sites increasingly incorporate clauses to address the ecological damage related to invasive plants in landscaping. For example, the International green Construction Code (IgCC), ASHRAE 189.1 Standard for the Design of High-Performance Green Buildings (ASHRAE 189.1), Leadership in Energy & Environmental Design (LEED) rating systems, and the Sustainable Sites Initiative rating system all contain requirements or credits to reduce the use and presence of invasive plants on a building site. The implementation of these requirements, however, is dependent on the existence of a valid list of invasive plants for the region in which the building is located. For example, the definition of invasive plant species in IgCC is as follows: INVASIVE PLANT SPECIES. Species that are not native to the ecosystem under consideration and that cause, or are likely to cause, economic or environmental harm or harm to human, animal or plant health, defined by using the best scientific knowledge of that region. Consideration for inclusion as an invasive species shall include, but shall not be limited to, those species identified on: 1. Approved city, county or regional lists. 2. State noxious weeds laws, 3. Federal noxious weeds laws. Existing State and Federal noxious weed lists are generally insufficient: most have not kept pace with the latest science in the field, and many focus predominantly on agricultural, rather than ecological, impacts. Furthermore, few local governments have yet to develop their own lists. With definitions (such as that in IgCC) dependent on the existence of local, State, and Federal lists, the invasive plant requirements in green building codes will have little effect. A standard is needed to provide government agencies as well as environmental, academic, and horticultural organizations a common approach to determining what plants are invasive to a specified area.
