Regional Impacts

Ecological ImpactCompetition
Styela clava is abundant in Southern California harbors, often forming dense patches with 100% cover (Lambert and Lambert 1998; Lambert and Lambert 2003). It and other introduced ascidians have replaced the native species Pyura haustor and Ascidia ceratodes in southern California harbors (Lambert and Lambert 1998).
