National parks are the keystone institutions of environmental conserva
tion. Because national parks make certain lands part of the state itse
lf, international agencies and nongovernmental organizations that prom
ote national parks propose, in effect, to alter the state, as well as
the local economy and state relations with social groups. Has internat
ional political pressure caused states to create national parks? I con
sider whether countries highly involved in international politics have
the largest proportions of land in national parks. I conclude that ma
ny states create minimal park systems as symbolic gestures to the inte
rnational community. Field researchers may find if easier to explain t
he success or failure of parks if they identity why state officials de
cide that adopting international conservation norms will enhance state
authority over people and state sovereignty over land.
