Development of Restoration Performance Curves for Streams in Southern California Using an Integrative Condition Index
Determining success of stream restoration projects is challenging, due to the disconnection between required monitoring periods and the actual time necessary to achieve ecological success. Performance curves c...

How accurate are probability-based estimates of wetland extent? Results of a California validation study
Estimates of wetland and stream extent and distribution form the basis for state and federal monitoring and management programs and guide policy development decisions. The current default approach, comprehensi...

Development and comparison of stream indices of biotic integrity using diatoms vs. non-diatom algae vs. a combination
Stream algal indices of biotic integrity (IBIs) are generally based entirely or largely on diatoms, because non-diatom (“soft”) algae can be difficult to quantify and taxonomically challenging, thus calling in...

Evaluation of Design-Based Sampling Options for Monitoring Stream and Wetland Extent and Distribution in California
Accurate estimates of the extent and distribution of wetlands and streams are the foundation of wetland monitoring, management, restoration, and regulatory programs. Traditionally, theses estimates have relied...

Validation of a wetland Rapid Assessment Method: Use of EPA’s level 1-2-3 framework for method testing and refinement
Wetland rapid assessment has become popular in a variety of applications. Because rapid assessments rely on observable field indicators as surrogates for direct measures of condition, they must be validated ag...

Influence of geologic setting on slope wetland hydrodynamics
Slope wetlands exist where topographic or stratigraphic conditions allow ground water to intersect the surface, creating a zone of perennial or near-perennial moisture. The condition and resiliency of slope we...
