Carrière Des Nerviens Regional Nature Reserve
The Carrière des Nerviens Regional Nature Reserve (in French ''Réserve naturelle régionale de la carrière des Nerviens'') is a protected area in the Nord-Pas-de-Calais region of northern France. It was established on 25 May 2009 to protect a site containing rare plants and covers just over . It is located in the municipalities of Bavay and Saint-Waast in the Nord department. The reserve was created to protect fifteen plants of regional interest and three plant communities listed in the Habitats Directive. Its flora are linked to calcium present in marl. It is located in a transition zone between the oceanic and semi-continental climates and that gives increased biodiversity, with typical species of the atlantic areas and others more continental. The reserve also plays a role in a wildlife corridor. The site consists of an old quarry of sandstone dated to the Famennian stage in the Late Devonian epoch. It was backfilled in the 1970s with marl. The new soil was re-colo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bavay
Bavay () is a commune in the Nord department in the Hauts-de-France region of northern France. The town was the seat of the former canton of Bavay.

Pioneer Species
Pioneer species are hardy species that are the first to colonize barren environments or previously biodiverse steady-state ecosystems that have been disrupted, such as by wildfire. Pioneer flora Some lichens grow on rocks without soil, so may be among the first of life forms, and break down the rocks into soil for plants.LICHEN BIOLOGY AND THE ENVIRONMENT, LICHENS OF NORTH AMERICA, Sylvia and Stephen Sharnoff/ref> Since some uninhabited land may have thin, poor quality soils with few nutrients, pioneer species are often hardy plants with adaptations such as long roots, root nodes containing Diazotroph, nitrogen-fixing bacteria, and leaves that employ transpiration. Note that they are often photosynthetic plants, as no other source of energy (such as other species) except light energy is often available in the early stages of succession, thus making it less likely for a pioneer species to be non-photosynthetic. The plants that are often pioneer species also tend to be wind ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Maubeuge
Maubeuge (; historical nl, Mabuse or nl, Malbode; pcd, Maubeuche) is a commune in the Nord department in northern France. It is situated on both banks of the Sambre (here canalized), east of Valenciennes and about from the Belgian border. History Maubeuge (ancient ''Malbodium'', from Latin, derived from the Old Frankish name ''Malboden'', meaning "assizes of Boden") owes its origin to Maubeuge Abbey, a double monastery, for men and women, founded in the 7th century by Saint Aldego, the relics of whom are preserved in the church. It subsequently belonged to the territory of Hainaut. The town was part of the Spanish Netherlands and changed hands a number of times before it was finally ceded to France in the 1678 Treaty of Nijmegen. As part of Vauban's ''pré carré'' plan that protected France's northern borders with a double line of fortresses, it was extensively fortified as directed by Louis XIV of France. Besieged in 1793 by Prince Josias of Saxe-Coburg-Saalfeld, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Environmental Monitoring
Environmental monitoring describes the processes and activities that need to take place to characterize and monitor the quality of the environment. Environmental monitoring is used in the preparation of environmental impact assessments, as well as in many circumstances in which human activities carry a risk of harmful effects on the natural environment. All monitoring strategies and programs have reasons and justifications which are often designed to establish the current status of an environment or to establish trends in environmental parameters. In all cases, the results of monitoring will be reviewed, analyzed statistically, and published. The design of a monitoring program must therefore have regard to the final use of the data before monitoring starts. Environmental monitoring includes monitoring of air quality, soils and water quality. Air quality monitoring Air pollutants are atmospheric substances—both naturally occurring and anthropogenic—which may potentially ...

Heritage Interpretation
Heritage interpretation refers to all the ways in which information is communicated to visitors to an educational, natural or recreational site, such as a museum, park or science centre. More specifically it is the communication of information about, or the explanation of, the nature, origin, and purpose of historical, natural, or cultural resources, objects, sites and phenomena using personal or non-personal methods. Some international authorities in museology prefer the term mediation for the same concept, following usage in other European languages. Heritage interpretation may be performed at dedicated interpretation centres or at museums, historic sites, parks, art galleries, nature centres, zoos, aquaria, botanical gardens, nature reserves and a host of other heritage sites. Its modalities can be extremely varied and may include guided walks, talks, drama, staffed stations, displays, signs, labels, artwork, brochures, interactives, audio-guides and audio-visual med ...

Environmental Education
Environmental education (EE) refers to organized efforts to teach how natural environments function, and particularly, how human beings can manage behavior and ecosystems to live sustainably. It is a multi-disciplinary field integrating disciplines such as biology, chemistry, physics, ecology, earth science, atmospheric science, mathematics, and geography. The United Nations Educational, Scientific and Cultural Organization (UNESCO) states that EE is vital in imparting an inherent respect for nature among society and in enhancing public environmental awareness. UNESCO emphasises the role of EE in safeguarding future global developments of societal quality of life (QOL), through the protection of the environment, eradication of poverty, minimization of inequalities and insurance of sustainable development (UNESCO, 2014a). The term often implies education within the school system, from primary to post-secondary. However, it sometimes includes all efforts to educate the public a ...

Japanese Knot Weed
''Reynoutria japonica'', synonyms ''Fallopia japonica'' and ''Polygonum cuspidatum'', is a species of herbaceous perennial plant in the knotweed and buckwheat family Polygonaceae. Common names include Japanese knotweed and Asian knotweed. It is native to East Asia in Japan, China and Korea. In North America and Europe, the species has successfully established itself in numerous habitats, and is classified as a pest and invasive species in several countries. Japanese knotweed has hollow stems with distinct raised nodes that give it the appearance of bamboo, though it is not related. While stems may reach a maximum height of each growing season, it is typical to see much smaller plants in places where they sprout through cracks in the pavement or are repeatedly cut down. The leaves are broad oval with a truncated base, long and broad, with an entire margin. The flowers are small, cream or white, produced in erect racemes long in late summer and early autumn. Related species in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Invasive Species
An invasive species otherwise known as an alien is an introduced organism that becomes overpopulated and harms its new environment. Although most introduced species are neutral or beneficial with respect to other species, invasive species adversely affect habitats and bioregions, causing ecological, environmental, and/or economic damage. The term can also be used for native species that become harmful to their native environment after human alterations to its food webfor example the purple sea urchin (''Strongylocentrotus purpuratus'') which has decimated kelp forests along the northern California coast due to overharvesting of its natural predator, the California sea otter (''Enhydra lutris''). Since the 20th century, invasive species have become a serious economic, social, and environmental threat. Invasion of long-established ecosystems by organisms is a natural phenomenon, but human-facilitated introductions have greatly increased the rate, scale, and geographic range of ...

Non-governmental Organization
A non-governmental organization (NGO) or non-governmental organisation (see spelling differences) is an organization that generally is formed independent from government. They are typically nonprofit entities, and many of them are active in humanitarianism or the social sciences; they can also include clubs and associations that provide services to their members and others. Surveys indicate that NGOs have a high degree of public trust, which can make them a useful proxy for the concerns of society and stakeholders. However, NGOs can also be lobby groups for corporations, such as the World Economic Forum. NGOs are distinguished from international and intergovernmental organizations (''IOs'') in that the latter are more directly involved with sovereign states and their governments. The term as it is used today was first introduced in Article 71 of the newly-formed United Nations' Charter in 1945. While there is no fixed or formal definition for what NGOs are, they are genera ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
