Put together by the Federal Agency for Nature Conservation (BfN), this compilation on nature conservation law provides external links to important EU regulations and directives. The European Union is both founded in law (primary law) and generates law (secondary law). Primary law consists of the constituting treaties of the European Union. Secondary law is the legislation created by EU institutions, notably regulations and directives. Regulations are binding in all of their constituent parts and thus apply directly in each of the member states. Conversely, directives are merely binding as to the result to be achieved, which is why they have to be transposed into national law by the member states. At EU level, it is largely directives that drive the development of nature conservation law.
