Editing Mount Parnassus (section)

===National Park===
The National Park of Parnassus was founded in 1938. The idea behind the park was to preserve the natural habitat, for which it was necessary to govern the disposition of its natural resources. However, the park did not include all the terrain considered to be in the range. The highest peaks were omitted.

Within a few years the park aspect of the land became dormant as Greece turned its attention toward ending the German occupation, and then after World War II, settling the Greek Civil War. Parnassus was in a unique position to serve as a center for resistance, as it had for the Greek war of independence. Battles were fought in the valleys surrounding the range.

When the wars were over and the region went back to being an active park, the new science of ecology brought changes to the park administration. Species were inventoried, endemic and endangered ones were identified, and the concept of a protected area was established. Parnassus National Park became a protected area for birds under the "Birds Directive." Subsequently, it acquired other protections under other laws as required by the EU. After 2000, it became Oros Parnassos, "Mount Parnassus," Natura 2000 protected area ID GR2410002. The two are not exactly identical. The national park is about {{convert|150|km2|acre|abbr=on}}. The Natura 2000 area is about {{convert|344|km2|acre|abbr=on}}, bringing the terrain not covered by the park under protection..

Among the endemic flora species under protection are the [[Abies cephalonica|Cephalonian fir]] tree and the Parnassian [[peony]] (''Paeonia parnassica''). In the Park are to be found birds of prey, wolves, boars, badgers, and weasels.
