We are working on the ecology of these invertebrates, particularly the ragworm (Nereis diversicolor), a significant ecological engineer, and of fishes that use these habitat.\u00a0 Saltmarshes are important as feeding areas for juvenile fish of several species, including bass which is commercially important, and internationally important wading bird populations.<\/p>\n<p>\u00a0In light of that it is interesting to hear EA (Environment Agency) claiming<\/p>\n<p style=\"padding-left: 30px;\">&#8220;we know that salt marsh loss is caused by sea level rise&#8221;<\/p>\n<p>This appears to be a local phenomena as UK is apparently the only country in the world where sea level rise causes salt marsh loss.<\/p>\n<p>And the evidence is what ?<\/p>\n<p>It is also interesting to hear EA state their responsibility is to respond to man made activities!<\/p>\n<p>Next is a clip of EA talking excitedly about a plan to flood 100 acres of\u00a0 Hill House Farm by river Orwell near Shotley.\u00a0 This represents about 1\/5\u00a0 of the farm which seems quite a large amount to lose, in a time of rising food shortages.<\/p>\n<p>In the video you hear Karen Thomas from EA stating with absolute certainty<\/p>\n<p style=\"padding-left: 30px;\">&#8220;salt marsh loss is caused by sea level rise&#8221;<\/p>\n<p><iframe loading=\"lazy\" width=\"640\" height=\"360\" src=\"http:\/\/www.youtube.com\/embed\/rNXe1M48IN0?feature=oembed\" frameborder=\"0\" allowfullscreen><\/iframe><\/p>\n<p>The farmer will be compensated for not farming part of his farm.<\/p>\n<p>It is important for people in UK to understand that such schemes are being promoted all around UK.\u00a0 The total cost, compensation and engineering, has been estimated to be \u00a32.6 billion.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Here is a YouTube video featuring Dr Rob Hughes\u00a0 &#8211; salt marsh ecologist from\u00a0 Queen Mary, University of London Richard Steward Robert Simper showing how salt marsh is being eroded by crabs and\/or ragworm.
