We conducted a field experiment in three replicate sea urchin barrens in Sitka Sound, Alaska in February of 2023, where we deployed pre-weighed Macrocystis pyrifera blades at discrete distances on four metre radial cables from caged adult P. helianthoides and control cages and reweighed after 24 hours. Our results suggest the chemical cue of P. helianthoides elicits a localised, species-specific landscape of fear that suppresses grazing, and that the non-consumptive effects of P. helianthoides on sea urchin behaviour may be important for kelp restoration.\n\ncdm_data_type = Other\nVARIABLES:\nRayID (unitless)\nSite (unitless)\nlatitude (degrees_north)\nlongitude (Long, degrees_east)\nTreatment (unitless)\nRepID (unitless)\nTreatRep (unitless)\nDate (unitless)\nTimeElapsed_hr (hours)\nRay (unitless)\nTrack (unitless)\nColor (unitless)\nDist_m (meters (m))\nKelpStartWt_g (grams (g))\nAttachedKelpEndWt_g (grams (g))\nDriftKelpEndWt_g (grams (g))\nTotal_KelpEndWt_g (grams (g))\nKelpChgWt_g (grams (g))\nKelpGrazed_g (grams (g))\nPercentKelpGrazed (unitless)\nFlags (unitless)\n | https://erddap.bco-dmo.org/erddap/metadata/fgdc/xml/bcodmo_dataset_942729_v1_fgdc.xml | https://erddap.bco-dmo.org/erddap/metadata/iso19115/xml/bcodmo_dataset_942729_v1_iso19115.xml | https://erddap.bco-dmo.org/erddap/info/bcodmo_dataset_942729_v1/index.htmlTable | https://osprey.bco-dmo.org/dataset/942729
