It is one of Kalmar County&#8217;s most valuable rivers and is a Natura 2000 site in its full length within the county.<\/p>\n<p>From its source, Lake Alstern, River Alster\u00e5n flows through varied terrain in two branches before reaching Lake Allgunnen, one of Sweden&#8217;s largest unregulated lakes. From Allgunnen, the water flows on through three outlets that join further downstream before the river enters into the Baltic Sea at Pataholm in Kalmarsund. The upper part of River Alster\u00e5n is dominated by coniferous forest and marshland, while the lower parts are characterized by farmland and deciduous forest. River Alster\u00e5n also passes wetlands and swamp forests on its way to the sea.<\/p>\n<p><strong>Biological values and threatened species<br \/>\n<\/strong>River Alster\u00e5n has high nature values thanks to its varied habitats. It is an important spawning ground for salmon and trout, but other species such as eel, sea lamprey, catfish, spined loach and bullhead are also present. In total, around 18 fish species have been reported in the river. However, salmon populations are in decline, making salmon a priority species in the management of the Natura 2000 sites.<\/p>\n<p>River Alster\u00e5n has a rich benthic fauna with rare and endangered species and significant flora and fauna. Birds associated with the aquatic environments include osprey, silver tern, white-tailed eagle and kingfisher. Another priority species under the EU Habitats Directive is the otter, which has declined drastically since the 1950s but is now recovering.<\/p>\n<p>The Alster\u00e5n estuary and the coastal areas of Kalmarsund are also part of the Natura 2000 site. These brackish water environments are rich in flora and support predatory fish species such as sea trout, pike and perch. The coastal ecosystems of Kalmarsund and the Alster\u00e5n estuary are affected by eutrophication and the populations of pike and perch are on a downward trend.<\/p>\n<blockquote><p>The river has a rich benthic fauna with rare and endangered species and significant flora and fauna.<\/p><\/blockquote>\n<p><strong>Environmental impacts and restoration needs<\/strong><br \/>\nFor a long time, River Alster\u00e5n was used for timber rafting, which led to the clearing of boulders and changes in the bottom substrate and hydrology. The river has also been dammed for mills and hydropower, and large wetlands have been drained, negatively affecting water flow.<\/p>\n<p>During the 1970s, water quality deteriorated due to acidification. However, the situation has improved through reduced acidification and extensive liming efforts. Nevertheless, according to the EU Water Framework Directive, River Alster\u00e5n has only a moderate ecological status due to a lack of connectivity, altered morphology and recurrent summer water shortages, which negatively affect ecosystems.<\/p>\n<p><strong>Restoration actions<\/strong><br \/>\nAccording to the Natura 2000 management plan, measures to ensure free migration, successful spawning and functioning hydrology are priorities. Within the Improve Aquatic LIFE project, a migration barrier will be removed, opening up 3 kilometers of the river. Habitatrestoration will be carried out on about 1 300 meters to restore habitats for plants and animals. About 23 hectares of wetland will be restored to improve the natural hydrology downstream. Measures will also be implemented in the coastal area to improve spawning and nursery conditions for predatory fish such as pike and perch.<\/p>\n<p>The measures will improve connectivity, hydrology, water quality, biodiversity and fish production, as well as benefit the Natura 2000 species salmon, byllhead and spined loach. They will also strengthen the stocks of the typical species lamprey, chub and minnow and help reduce the risk of drought.[\/vc_column_text][\/vc_column][\/vc_row][\/vc_section][vc_section disable_element=&#8221;yes&#8221; el_name=&#8221;Projektf\u00f6rfarande&#8221;][vc_row][vc_column width=&#8221;1\/2&#8243;]<style type=\"text\/css\">#ut_custom_heading69dfccd492242 { color:#008060; }#ut_custom_heading69dfccd492242 { font-size:20px !important;line-height:130% !important; }#ut_custom_heading69dfccd492242 { text-align:left; }@media (min-width: 768px) and (max-width: 1024px) { #ut_custom_heading69dfccd492242 { text-align:left; } }@media (max-width: 767px) { #ut_custom_heading69dfccd492242 { text-align:center; } }<\/style><h3 id=\"ut_custom_heading69dfccd492242\" data-responsive-font=\"h3\" data-responsive-font-settings=\"{&quot;base-font-size&quot;:&quot;global&quot;,&quot;font-size&quot;:{&quot;desktop_large&quot;:&quot;20&quot;},&quot;base-line-height&quot;:&quot;global&quot;,&quot;line-height&quot;:{&quot;desktop_large&quot;:&quot;130&quot;},&quot;base-letter-spacing&quot;:&quot;global&quot;}\" class=\"ut-custom-heading-module   vc_custom_1739286393713\" ><span class=\"\" >Restoration of xxx<\/span><\/h3><div class=\"wpb_content_element \"><style type=\"text\/css\">#ut_header_69dfccd49291e h2.section-title { font-size:50px !important;line-height:125% !important;letter-spacing:-0.03em; }<\/style><header id=\"ut_header_69dfccd49291e\" class=\"section-header  ut-no-title-linebreak-mobile ut-no-lead-linebreak-mobile pt-style-7 header-left header-tablet-left header-mobile-center element-with-custom-line-height\"><div class=\"element-with-custom-line-height\" ><h2 data-title=\"Here we are now\"  data-responsive-font=\"section_title\" data-responsive-font-settings=\"{&quot;base-font-size&quot;:&quot;global&quot;,&quot;font-size&quot;:{&quot;desktop_large&quot;:&quot;50&quot;},&quot;base-line-height&quot;:&quot;global&quot;,&quot;line-height&quot;:{&quot;desktop_large&quot;:&quot;125&quot;},&quot;base-letter-spacing&quot;:&quot;global&quot;,&quot;letter-spacing&quot;:{&quot;desktop_large&quot;:&quot;-0.03&quot;}}\" class=\"section-title  \"><span>Here we are now<\/span><\/h2><\/div><div data-delay=\"0\" class=\"lead \"><p>Fusce augue nibh, rhoncus quis mattis et, aliquam sit amet lorem.
