You will also need to register with Polk County Conservation: https://polkcountyiowa.volunteermatters.org/project-catalog/93 Join staff on select evenings this fall as we gather native prairie seed ready to harvest in restored tallgrass prairie habitat. Seed harvesting is both a relaxing and rewarding volunteer experience that directly benefits Iowa’s critically endangered tallgrass prairie ecosystem. Alongside staff and fellow volunteers, you’ll collect seed from plants ready for harvest. These seeds will be planted across the county and grow into deep-rooted native plants that naturally filter water, trap excess nutrients (like nitrates) before they reach rivers, and protect against flooding and soil loss. Your efforts directly help Polk County Conservation expand prairie across our parks and conservation areas, reducing contaminants at their source and improving water quality for everyone. You’ll also gain plant identification skills, learn about the historical and ecological importance of this habitat, and be part of a team directly tackling Iowa’s biggest environmental challenges.
