A king sized blanket covering the ground near Ladybird Lake is actually a “seed island” or a streambank restoration method.Austin is known for a few islands like Red Bud Isle, Treasure Island, and heat islands, but be on the lookout for more islands appearing in our parks.

What could be mistaken for a king sized blanket covering the ground near Ladybird Lake is actually a “seed island” or a streambank restoration method that volunteers can learn and implement.

Seed island is the Watershed Protection Department’s technical term for a patch of native grasses and flowers.  To help promote native plant growth in our grow zones, the site must be managed to improve soil, remove invasive plants and enrich the native plant community, especially in areas with very little growth of native seedlings.
