Abstract
In contrast to the jeopardy caused to commonproperty regimes by conditions of open access, factorssuch as boundary ambiguity, shifts, and maintenancefailures are the causes of a different set of problemsin the Los Haitises National Park, a controversialprotected area in the Dominican Republic. Survey data,historical sources, and digital mapping informationoverlaying past boundary changes show that this areahas undergone two decades of design modifications inits perimeters. Despite a long history of communalownership in that country, there appears to be littlelikelihood of transforming this tradition into amodern common property regime of use to community andenvironment in the park‘s buffer zone. This is due, atleast in part, to its highly porous, constantlychanging boundary, a source of on-going, open-accessproblems among local cultivators peripheral to thepark
