Indicator Species
  1. Any biological species that defines a trait or characteristic of the environment.

Infill Development
  1. Infill development is the re-use of land or existing developed sites within an urban/suburban area. Infill development promotes better use of sites through reuse and repositioning of obsolete or underutilized buildings. Infill uses vital land left vacant during early development and contributes to community revitalization. Infill is representative of smart growth. Infill development is valuable not only for the environmental benefits of using land more efficiently and directing growth into existing urbanized areas, but also the benefit that quality projects bring to neighborhoods and communities. Good infill conserves open space, helps to energize communities and contributes to jobs, housing and area sustainability. [source: Municipal Services Agency, Infill Development Program:]

Integrated Pest Management
  1. An effective and environmentally sensitive approach to pest management that relies on a combination of commonsense practices. IPM programs use current, comprehensive information on the life cycles of pests and their interaction with the environment. This information, in combination with available pest control methods, is used to manage pest damage by the most economical means, and with the least possible hazard to people, property, and the environment. The IPM approach can be applied to both agricultural and non-agricultural settings, such as the home, garden, and workplace. IPM takes advantage of all appropriate pest management options including, but not limited to, the judicious use of pesticides. In contrast, organic food production applies many of the same concepts as IPM but limits the use of pesticides to those that are produced from natural sources, as opposed to synthetic chemicals.
