- Control weeds, including invasive grasses, as necessary to reduce competition and create a more favorable environment for native seed germination and establishment.
- Remove woody debris and thatch to stimulate seed germination and reduce the risk of fire. Some standing woody material can be left behind depending on the site and management objectives.
- If soils are compacted, scarify or aerate them to improve water infiltration and root growth.
Step 2: Native Seed Selection and Collection
- Select native grass and forb species that are adapted to the local climate, soil conditions, and desired habitat type.
- Consider using a mix of species with different growth habits, flowering times, and root structures to enhance species diversity and resilience.
- Collect seeds from native plant populations in the same region or from a nearby ecoregion to preserve local genetics.
Step 3: Seeding
- To get good soil seed contact and reduce seed loss to rodents and birds, broadcast seeds and slightly rake or harrow them into the soil to about ¼ to ½ inch deep.
- It may be best to apply a thin layer of weed-free straw, mulch or compost over the entire seeding area if there are concerns about wind or water erosion or loss of moisture before seeds germinate.
Step 4: Irrigation & Weed Control
- Ensure adequate moisture with supplemental irrigation if rainfall is infrequent or insufficient, especially during the first growing season.
- Control weeds that compete with native seedlings by spot spraying or hand-pulling.
Step 5: Monitoring & Adaptive Management
- Monitor the restored area regularly to assess plant growth, species establishment, and any potential threats such as weeds, pests, or diseases.
- Regularly monitor the site and adjust management practices using an adaptive management approach to ensure long-term success. Make necessary adjustments based on results of regular monitoring.
Additional Tips:
- Incorporate cultural burning or prescribed fire, if appropriate, to stimulate native seed germination, control invasive plants, and promote diversity.
- Consider using native plant containers, tree shelters or other protective measures to safeguard seedlings from herbivores and harsh weather.
- Introduce pollinators, such as native bees and butterflies, to enhance native plant reproduction and ensure long-term success
- Engage with local communities, including indigenous peoples and landowners, to support native grassland restoration efforts and foster a sense of stewardship.
