Assessing the development of newly created habitat for wintering estuarine birds

摘要: Abstract The term coastal squeeze has been used to describe the process whereby hard flood defences in areas subjected relative sea level rise constrain ability of an estuarine system respond naturally, thus leading a loss intertidal habitat, with associated potential reduction carrying capacity for fish and bird populations. squeeze, coupled long-term effects climate change, generated need create or restore habitats estuaries. In Humber Estuary (UK) it is estimated that over 700 hectares habitat will be lost due rising levels next 50 years. order address this net loss, known as ‘managed realignment’ employed management tool, sections are moved inland offset losses capacity. On Humber, Paull Holme Strays site, east Hull, first managed realignment site on estuary become operational. at was breached September 2003 creating approximately 80 habitat. assess development waterbird assemblage ultimately success creation technique, monthly ornithological surveys were undertaken newly created mudflat fronting site. analysis avifaunal usage data demonstrated within 3 years creation, new capable supporting low water, functional similar composition adjacent existing areas. At Strays, achieved little ongoing habitats.
