|Trails of Arcata Marsh and Wildlife Sanctuary|
Prior to the integration of salt marshes and treated wastewater, the oxidation pond at the Arcata Wastewater Treatment Plant was a popular spot for birding enthusiasts. The public's interest in the recreational benefits of the of the marshes and ponds of the Arcata Wastewater Treatment Plant was one of the factors that ultimately lead to the creation and expansion of the Arcata Marsh and Wildlife Sanctuary's public trails.
The trails are maintained by the City of Arcata, the California Conservation Corp, and volunteers. Much of the current restoration activities at the Arcata Marsh and Wildlife Sanctuary focus on the removal of non-native invasive plant species such as pampas grass, teasel, thistle, and scotch broom. There is also ongoing restoration work, in various stages of development, being done on the 75-acre marsh expansion project located northwest of I Street.
