In order to learn more about the ecosystem at Pillar Point we examined the data from Global Biotic Interactions. GloBI provides species interaction data such as predator-prey, parasite-host. We retrieved all the species that have 10 or more observations from Intertidal Biodiversity Survey at Pillar Point in iNaturalist, and screened the list of interacting taxa for overlap with GBIF species and eDNA species.
