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.
