Abstract Seagrasses and their habitat are declining
worldwide. Zostera noltii in the Canary Islands has been
drastically reduced, mainly by anthropogenic disturbance,
to three small surviving patches in a single harbor in
Lanzarote. A previous genetic study, using neutral micro-
satellite markers, revealed that these patches consist of a
single clonal individual. Here, an assignment test, using
microsatellite data, was used to locate the most likely
population of origin from a set of possible donor popula-
tions. Our results show that the Moulay Bousselham pop-
ulation in northern Morocco is assigned as the most likely
population of origin (88%), although the probability of
being at one generation time distance is low (2.7%).
