Aptos Creek Large Woody Debris (LWD) Project
California State Parks, with support from the Resource Conservation District of Santa Cruz County (RCD), is launching a habitat restoration project in The Forest of Nisene Marks State Park to improve the health of Aptos Creek and the surrounding forest.
What’s Happening
Where: Forest of Nisene Marks State Park
When: September 23 – through October 2025
What: Crews will place fallen trees and logs in areas along approximately 1.5 miles of Aptos Creek
Why: To help restore the natural processes that shape healthy streams and provide habitat for fish and wildlife
Why Add Wood to Streams?
Streams need more than just water to stay healthy. A “messy” stream is often a healthy one. Large pieces of wood and branches are a natural part of creek ecosystems. They:
- Slow down water during storms
- Trap sediment and improve water clarity
- Create pools and riffles that fish need to rest, hide, and feed
- Reconnect the stream to its natural floodplain which can reduce flooding where it isn’t wanted.
- Provide shelter and food for countless plants and animals
Benefits for Fish and Wildlife
This project supports endangered salmonids like steelhead trout by:
- Creating hiding places from predators
- Building cool, deep pools where fish can rest
- Boosting the natural food web that young fish depend on
Benefits for People
- Healthier Forests: Stronger, more resilient streamside trees and vegetation
- Better Water Quality: Cleaner water and reduced sediment
- Flood Protection: Wood in the right place can slow flows and reactivate flood plains reducing downstream flooding and limiting bank erosion
- Better Park Experience: A more natural and thriving creek for visitors to enjoy
What Visitors Can Expect
- Temporary Trail Closures: Parts of Porter Trail and Aptos Creek Fire Road may close briefly while crews work.
- Work Near the Creek: You may see work crews and hear saws near the creek.
- Long-Term Rewards: Once work is done, visitors will enjoy a healthier, more vibrant stream and forest ecosystem.
