Biosphere polygons

Biosphere grounds or polygons have been around since 2004. Their network is being created as part of a national monitoring system concerned with the state of complex and special biological diversity, and as part of Europe‘s ecological network Natura 2000. Biosphere reserves will facilitate the monitoring, control and prediction of changes in natural systems and the condition of certain species. Almost all have been established for the protection of bird species of greatest Community interest in implementing the requirements of the European Union Birds Directive.
