Abstract

Long-term observations in an enclosed estuarine branch in The Netherlands showed a remarkably strong correlation between water column levels of dissolved silicon (DSi) and standing stock of eelgrass Zostera marina. Si levels in the leaves of Z. marina varied between 0.02 and 0.66% of tissue dry weight; they were lower in the declining population than in other populations in neighbouring areas. We hypothesize that decreased concentrations of DSi, which may coincide with eutrophication of coastal waters, may be a factor in the worldwide decline of estuarine eelgrass populations whose significance has so far been ignored.
