More than any other continent, Europe is a mosaic of countries with relatively humanised landscapes.
The ecosystems and processes affecting biological diversity are by large not limited by national borders.
Thus measures taken in a local, regional or national context are often insufficient or even fail. Only an international
framework, supporting coordinating initiatives, facilitates the approach of developing a common safeguard for biodiversity
and landscape. The Council of Europe has pioneered such cooperation since the early 1970's.
