2020-2021 Executive Summary
Southern California environmental managers and scientists spend an estimated $50 million every year on monitoring aquatic environments, but have struggled to answer the big-picture questions being asked by the public: “Is it safe to swim in the ocean?” “Are locally caught fish safe to eat?” and “Are local ecosystems adequately protected?” Most of this money is allocated to keep tabs on the relatively compact areas that surround specific outfalls – monitoring that is required under state and federal laws. Consequently, when scientists compile this compliance-based monitoring data from dozens of agencies, the resulting regional picture is incomplete. Recognizing this challenge, SCCWRP has stepped in to coordinate and facilitate wide-scale regional monitoring programs across a variety of habitats, including streams, wetlands, estuaries, beaches and coastal waters. For each monitoring program, SCCWRP works with dozens of local and regional agencies to standardize data collection and coordinate analysis efforts, leveraging the limited resources of many to obtain comprehensive data on some of the region’s most pressing environmental challenges. These programs are among the top regional monitoring programs in the nation and have served as models for developing similar programs internationally.
SCCWRP’s best-known monitoring program is the Southern California Bight Regional Monitoring Program, conducted every five years since the mid-1990s. The ongoing program mobilizes participating agencies to collect data from across a much greater expanse than just their outfall zones, allowing environmental managers to paint a comprehensive picture of the health of coastal waters that stretch from Point Conception in Santa Barbara County to just south of the U.S.-Mexico border.
The Bight program’s freshwater counterpart, the Southern California Stormwater Monitoring Coalition Regional Watershed Monitoring Program, was launched in 2009 to monitor an area that stretches from the Ventura River in Ventura County to the Tijuana River straddling the U.S.-Mexico border. The key to success in developing integrated monitoring designs is SCCWRP’s ability to bring all parties to the table – from local and regional agencies to state and national entities – to work toward agreement on goals, study design and data interpretation. Not only do the comprehensive data sets help environmental managers establish appropriate priorities and goals for addressing big-picture challenges, but regional monitoring also fosters productive interactions among dischargers and regulators as they develop and collaboratively interpret monitoring information and implement findings. Regional monitoring also provides an important launching platform for SCCWRP’s member agencies and research collaborators to test new technologies and assessment tools.
This year, SCCWRP will continue to facilitate the 2018 cycle of the Southern California Bight Regional Monitoring Program, known as Bight ’18, and the SMC Regional Watershed Monitoring Program as it kicks off its 2019-2023 cycle. SCCWRP’s focus for 2020-21 will be on:
- Regional marine monitoring (Bight ’18): SCCWRP is continuing to work with more than 80 partner agencies to advance the sixth cycle of the Southern California Bight Regional Monitoring Program (Bight ’18). This integrated, ongoing regional monitoring collaboration includes five major study elements: Sediment Quality, Ocean Acidification, Harmful Algal Blooms, Trash and Microbiology. SCCWRP is facilitating the development of study designs, data management plans, data analysis, and co-authoring of final assessment reports. The Bight program, which dates back to 1994, provides holistic answers to questions regarding the extent and magnitude of anthropogenic impacts and the range of natural variability upon which scientists evaluate these impacts. The Bight program covers approximately 1,500 square miles of near-coastal ocean and has sampled at more than 2,000 sites. Bight ’18 includes monitoring of new habitats not previously monitored, new sampling techniques, new pollutants, and testing of new ecosystem response assessment tools.
- Regional watershed monitoring: SCCWRP is facilitating the third cycle of the Southern California Stormwater Monitoring Coalition (SMC) Regional Watershed Monitoring Program, which runs from 2019 to 2023. This year, SCCWRP will continue finalizing study designs and coordinating field sampling activities for the regional survey, which samples at more than 500 sites across all 17 major watersheds between the Ventura and Tijuana Rivers. Among the largest watershed programs in the nation, the program encompasses data on water quality, physical habitat and riparian condition, and biological communities, including benthic invertebrates and algae. The monitoring questions for the third five-year cycle are: (1) What are the extent and magnitude of impact in Southern California’s streams? (2) Are the extent and magnitude getting better or worse? (3) What are the stressors responsible for the impacts observed?
- Statewide estuary monitoring: SCCWRP is working with a statewide team of partners to develop a monitoring and assessment framework for estuaries across the state. The framework will address which aspects of the ecosystem should be assessed, and how to evaluate the condition of the these highly heterogenous systems. SCCWRP is focusing initially on the 24 estuarine Marine Protected Areas (MPAs) across the state. SCCWRP will develop recommendations on suites of indicators (and associated sampling protocols) across multiple trophic levels that can be used to assess key estuarine functions. SCCWRP also will develop approaches to contextualize the resulting information using comparisons to reference, paired estuaries and regional ranges of condition. Field testing of the recommended indicators will follow.
