Summary
[edit]DescriptionRestoration measures, Barton Broad - geograph.org.uk - 690476.jpg |
English: Restoration measures, Barton Broad Barton Broad used to suffer from severe eutrophication and silting. The nutrient-rich mud was pumped out, and an ecological intervention put in place - excluding fish from certain areas, in order to increase the population of Daphnia (water flea) and thereby control the algae. Lower algae levels mean clearer water, and greater plant growth, which in turn provides shelter for Daphnia from predation by fish. This photo shows one of the fish "exclosures" - below the floats, mesh curtains hang to the bottom of the broad.
