Two Revegetation Strategies for Wetland Restoration

Native Seeding

Last fall, a seed mix was spread across our 44 acre restoration site at Bel Marin Keys, in Novato, CA. 700 lbs of native seed were spread using a hydroseeding machine.The plants in the seed mix have qualities that specifically compete with the non-native weeds that come up on the site, making it easier for our perennial wetland plants to successfully establish at the restoration site.

Half a year later, spring flowers have sprung! The native seed mix successfully rooted and grew into healthy plants in the seasonal wetland. As the plants dry out through summer, the seeds they produced will reseed the site and grow new plants next year.

Another method of establishing plants at our restoration sites, more common for Save The Bay, is outplanting. Native plants are propagated and grown in our nursery, then transplanted out on the shoreline. Outplanting allows the plants to grow in easier and more controlled environments in our nursery and establish strong roots systems. Partner organizations and volunteers help our Habitat Restoration Team outplant at our restoration sites.

Overgrown nursery beds

The plants growing in the nursery beds will be outplanted to the seasonal wetland this coming fall and winter.
