Mattley Meadow


Mattley Meadow is an un-restored meadow which includes both public and private lands in a remote area near the southwest boundary of the Mokelumne Wilderness on the Calaveras Ranger District (CRD), Stanislaus National Forest.  The meadow is at the headwaters of Mattley Creek, a tributary to the North Fork of the Mokelumne River.  Mattley Meadow was identified and prioritized as a restoration project by the CRD collaboratively with the Amador-Calaveras Consensus Group (ACCG) in the ACCG Cornerstone Project, a Collaborative Forest Landscape Restoration Project.  A final restoration design and necessary permits were acquired to implement the project in 2022. Primary goals are to reduce severe erosion of the meadow, re-invigorate a large aspen stand and increase Sierra Nevada yellow-legged frog (SNYLF) habitat and population numbers in Mattley Meadow.  Coupled groundwater wells and piezometers (6 each) were installed in two transects across the meadow by CRD staff in 2015 to begin pre-restoration monitoring efforts
