Increasing variation in key ecological processes can signal impending state shifts in ecosystems. In a rocky intertidal meta-ecosystem consisting of three distinct regions spread across 260 km of the Oregon coast, we measured % cover of sessile spaceholders over time (2011-2024) in undisturbed and annually cleared plots. We show that annually cleared plots are characterized by communities that exhibit signs of increasing destabilization (loss of resilience) over the past decade despite persistent community states. In all cases, recovery rates slowed and became more variable over time. The conditions underlying these shifts appear to be external to the system, with thermal disruptions (e.g., marine heat waves, El Niño–Southern Oscillation) and shifts in ocean currents (e.g., upwelling) being the likely proximate drivers. Although this iconic ecosystem has long appeared resistant to stress, the evidence suggests that subtle destabilization has occurred over at least the last decade.\n\ncdm_data_type = Other\nVARIABLES:\nPhotoID (unitless)\nPlotID (unitless)\nProject (unitless)\nState (unitless)\nRegion (unitless)\nCape (unitless)\nSiteCode_STARS (unitless)\nSite (unitless)\nlatitude (degrees_north)\nlongitude (degrees_east)\nZone (unitless)\n...

At each of four wave-exposed sites with fairly uniform large rock benches, we placed and digitally photographed 50 x 50 centimeter (cm) quadrats at defined tide heights across the vertical extent of the shoreline during spring low tides using a laser level. At each tide height, we placed 10 quadrats spaced in an approximately uniform pattern to sample the entire benches, while avoiding irregular topographic features such as tide pools and large cracks, thereby establishing 10 sampling paths down the shore. Sampling heights were defined at 0.2-meter (m) intervals, occasionally at 0.1 m intervals and referenced to markers at the sites of known tidal height. Surveys were made annually from 2014-2017 in July-August following the same general methods. Quadrat locations were not identical from year to year, but followed the same general paths from one year to the next, allowing some degree of control over topographical and hydrodynamic differences across the bench from one year to the next. Photographs of the upper and lower halves of each quadrat were analyzed separately by computer in the lab for the percentage of area covered of each visible organism to the lowest taxonomic level identifiable in non-destructive photographs. The resulting data provide a picture of variability in sessile species composition across time and space along a strong gradient of environmental change, including documenting temporal variability of populations, changes in sea level, effects of changes in the abundance of key species via disease and climate variation, and determinants of zonation.\n\ncdm_data_type = Other\nVARIABLES:\nSite (unitless)\nSample_Date (unitless)\nTransit (meters)\nMarker (meters)\nTide_Height (meters)\nQuadrat_number (unitless)\nUpper_Lower_Half (unitless)\nBare_Rock (number of occupied subsquares)\n...
