Protection of natural ecosystems

Neptune Grass or Mediterranean tapeweed (Posidonia oceanica) is endemic to the Mediterranean Sea. This priority seagrass species forms large underwater meadows that are an important part of the marine ecosystem. However, there have been declines in its population due to mechanical damage, coastal development and eutrophication.
The main objective of the intervention was to safeguard and to restore 2 Natura 2000 network sites for the conservation of P.oceanica habitat in the Lazio region(1), being the NBS intervention the restoration/protection of the underwater meadows and the improvement of the awareness/importance of this marine habitat type, a priority for conservation(EU Habitats Directive).

Bog Meadows is the last surviving remnants of the river Blackstaff's floodplain, which originally extended over 1,000 acres (Ref 3). This is an urban oasis composed of a mosaic of wetland, meadows, ponds, woodland, shrubs, and stream (Ref 1). It situated at the heart of Belfast City and is the last large area of the Blackstaff floodplain that has not been developed. The area is an important site for both breeding and overwintering birds(Ref 3). The Bog Meadows Enhancement Project aimed to improve the access, grazing infrastructure, and overall appearance of the site. It was hoped that cattle grazing will encourage wildflowers to attract insects, birds etc. (Ref 2).

The Forest of Belfast is an imaginative label for urban tree initiative launched in the 1990s with the aim of conserving and managing existing trees, increasing the planting of suitable trees, particularly in places of public access like parks, and in promoting an interest in and an appreciation of trees and forestry(Ref 3). The project was officially launched in June 1992 (Ref 1). It is active throughout the urban area of Greater Belfast, including Belfast City. It brings together partners from the statutory sector, voluntary groups, businesses, and individual residents who become volunteer Tree Wardens. It shows how urban forestry can forge partnerships between central and local government, environmental organizations and city dwellers. (Ref 1). Forest of Belfast initiative was wound up towards the end of 2010 (Ref 6).

Győr and its surroundings boast many rivers, streams and lakes, and experiences intense flooding almost every year. The main goal of Nagy-Pándzsa project was to reduce the risk of flood and to regenerate the Nature 2000 area (Reference 7). Due to the reconstruction of the water transporting feature and the reconstruction of the flood-gate, the flood protection could improve and the pollution of waters could decrease. Therefore, the conditions of flora and fauna of waters improved and the size of the utilizable area increased (Reference 8).

The Sowe Valley Project was a community-based project focusing on rivers restoration. It aimed to link the local community with the Sowe River Valley and to improve the valley’s biodiversity and habitats for the benefits of people and wildlife. (Ref. 2, 6, 11-13)

The South Pennine Moors is a conservation area in the Natura 2000 network. This site is crucial for active blanket bog and is part of two Special Protection Areas in the Birds Directive, including golden plover, dunlin, short-eared owl and merlin, dependent on the blanket bog for breeding and feeding. The conservation status of the site is threatened due to sulphate and nitrate pollution, causing severe depletion of crucial sphagnum moss cover. Fire damage has led to more extreme erosion than if the moorlands had remained sphagnum-rich. The restoration of favourable conditions thereby depends on re-establishing a sphagnum-rich bog. (3)
The project included three Natura 2000 sites, the Peak District Moors (South Pennine Moors Phase 1), South Pennine Moors Phase 2 and South Pennine Moors (3).

The center of the project is the lake Patria, which is the subject of a regeneration process with the creation of an archaeological and environmental park, providing several ecosystem services with the creation of green and blue corridors. There are a few challenges to this project, such as lack of financial support, urban and social fragmentation, and possible privatization of public spaces (Ref.3).
The project is still in its planning phase, 11 years after the feasibility study was published. In the local media, it is mentioned that in 2019 the authorities awaited the green light by the Region which will have to issue the impact assessment certificate. Once the certificate has been obtained, they will proceed with the approval of the executive project in order to then be able to call the tender (Ref. 4).

Ben Rhydding Gravel Pits Nature Reserve has a variety of habitats. The site is largely artificial, originating from former gravel pits. The river gravels were of good quality and represented an important local source for the construction industry. The pits ceased to be worked in 1970’s and flooded. Infill materials - a variety of materials have been used: building rubble, soil and treated sewage residues from the treatment plants. Plant materials and soil from parks, gardens and building sites have added to the bio-diversity. The reserve is owned by Bradford Council and managed by Wharfedale Naturalists Society volunteers. (reference 1) With the support of Natural England, the site was declared a Local Nature Reserve in October 2013. (ref 7).

The Schwanheimer dune is one of the few inland dunes in Europe. Sand, silver grass and gnarled pines shape the landscape, but also orchards and ponds are part of it (8). The area was designated as a nature reserve by the State of Hesse in 1984. Since its expansion in 2002, it now covers 58.5 hectares. Since 2003 it has also been protected as a Flora-Fauna Habitat area under European law contributing to the Natura2000 landscape (8). An approximately 400-meter-long boardwalk made of chestnut wood leads through the center of the dune on which visitors can enjoy nature on site - without harming it (8, 10). It was built in 1999 and completely rebuilt in 2017 with a lot of effort on the old route (8).

BIO.FOR.POLIS is a project for the cities of Caserta and Napoli, aiming at improving the biodiversity of the two forests under study. Their projects deal with the construction of streams within the Castelvolturno forest to connect the different parts of it. The two forest areas localized within an urban environment aim to improve the conditions of the ecosystems in a condition of human pressure. This is explicitly considered as a climate mitigation strategy. (Ref.1.)
