Contribute to regional diversity of flora and provide habitat for native wildlife by conserving existing native plant communities and installing vegetation that contributes to plant communities native to the ecoregion.
- Conserve existing native plant communities and/or restore native plant communities that, according to the SITES Native Plant Communities Calculator, equal a native plant community score of at least:
- 20 percent total native plant community score 4 points
- 40 percent total native plant community score 5 points
- 60 percent total native plant community score 6 points
- Conserve a percentage of the site’s existing native plant communities in Vegetation and Soil Protection Zones (VSPZs) (see Pre-Design P2.3: Designate and communicate VSPZs).
- The requirements apply to existing native plant communities, as identified in the site assessment (see Pre-Design P2.2: Conduct a pre-design site assessment), in which evidence of human disturbance is minimal and exotic and invasiveplants make up less than 10 percent of the total area of existing native plant communities.
- Make conservation calculations by surface area. Each area conserved must be contiguous and a minimum of 2,000 square feet (185.81 square meters).
- Restore a percentage of the site’s final vegetated area with native plant communities.
- Make restoration calculations by surface area of vegetated area, using estimated vegetated cover within 10 years of installation. Each area restored must be contiguous and a minimum of 2,000 square feet (185.81 square meters).
- Ensure the section of the site assessment (see Pre-Design P2.2: Conduct a pre-design site assessment) is complete and indicates the original area and characteristics of existing native plant communities on site.
- Ensure the section of the site maintenance plan (see O+M P8.1: Plan for sustainable site maintenance) is complete and describes the ongoing management activities to protect the integrity of VSPZs.
- Native plants can express multiple styles of design.
- On sites with existing native plant communities, design the site to minimize damage to existing healthy native plant communities, especially those areas that provide opportunities for wildlife habitat connectivity.
