This paper analysis the occurrences of staging and wintering herbivores (i.e. Mute Swan <em>Cygnus olor</em> and Coot <em>Fulica atra</em>) in relation to available food resources. It was concluded that the proportion of <em>Zostera</em> and <em>Ruppia</em> consumed by the birds during September–March was about 10% of the available standing crop in the autumn or less. During ice-periods large parts of the available feeding areas are covered by ice, and during an extended ice-period in 1995/1996 the calculated food consumption for the ice-free areas was of the same magnitude as the calculated standing crop of food plants.</p>}, number={1}, journal={Ornis Svecica}, author={Nilsson, Leif}, year={2005}, month={Jan.}, pages={13–21} }
