After 1945, those responsible for conservation in Germany resumed their
work with a relatively high degree of continuity as far as laws and
personnel were concerned. Yet conservationists soon found they had
little choice but to modernize their views and practices in the
challenging postwar context. Forced to change by necessity, those
involved in state-sponsored conservation institutionalized and
professionalized their efforts, while several private groups became more
confrontational in their message and tactics. Through their steady and
often conservative presence within the mainstream of West German
society, conservationists ensured that by 1970 the map of the country
was dotted with hundreds of reserves, dozens of nature parks, and one
national park. In doing so, they assured themselves a strong position to
participate in, rather than be excluded from, the left-leaning
environmental movement of the 1970s.
