Zostera japonica (=Nanozostera japonica, dwarf eelgrass) is an aquatic plant that forms dense stands in shallow, sheltered bays and estuaries. Populations of Z. japonica have been found in Humboldt County. Z. japonica often invades areas with little or no natural or human disturbance and also shows a positive relationship with disturbance. Z. japonica lives as an annual, overwintering as buried seeds, or a short-lived perennial. It reproduces vegetatively through rhizomatous cloning and sexually through seed production. The dispersal of the seeds, both within and between estuaries, may be aided by waterfowl species. Z. japonica has been shown to rapidly expand in the spring and summer.Rating: Moderate
