The document provides science based information and guidelines related to natural systems and biodiversity. Four natural systems are explored in detail: wetlands, riparian areas, forests, and grasslands. Guidelines and parameters are provided for each natural system, such as:
·         targets (e.g. 75% of stream length should be naturally vegetated)
·         percent retention or cover (e.g. 40% of historic watershed wetland coverage should be protected and restored)
·         setbacks, buffers and protection zones
·         shape and diversity
·         restoration goals
·         proximity to other natural systems
·         where to protect and restore
·         fragmentation and corridors
·         location and patch size
·         habitat quality
The guidelines are intended to assist decision makers in setting restoration targets and restoration project locations, as well as a science based reference for natural heritage practitioners.
