Balkan chamois (Rupicapra rupicapra balcanica), a goat–antelope species (native to Europe and the Carpathian Mountains) management has been done with species available from the park. During 1963–1987, 256 chamois were successfully introduced in 13 other areas in Bosnia and Herzegovina, Croatia . Some of the bird species reported from the Perućica forests are: golden eagle, grouse, peregrine falcon, blackbird and rock partridge. Conservation and protection Sutjeska National Park is an affiliated member of the EUROPARC Federation. Considering the overexploitation of natural resources (including illegal extraction of firewood), the World Bank has supported a major multipurpose management plan for biodiversity conservation, forestry management, cultural heritage conservation, tourism, and socioeconomic development. The projects cover physical improvement of existing Protected Areas, and the establishment of critical new priority areas with funding of US$2.76 million (including US$1.4 million from the Global Environment Facility). The project started in 2006, includes the existing Sutjeska National Park and also the Kozara National Park with a focus on plans of ecosystem development, participatory land-use planning, creation of new infrastructure, and limited small-scale rehabilitation of buildings, considered essential for improving the operation of the existing park. Infrastructural development includes trail improvements and new trail creation, signage repair, resting places, and demarcation of park boundaries. An exclusive training program is also part of the project scope. Since the 1960s, infrastructural development has posed a major difficulty so as to minimize impact upon the environment. Future transboundary protection Trnovačko Lake, just outside the park and the borders of Bosnia and Herzegovina, is a glacial lake at an elevation of , is long and wide set amidst a "huge amphitheater of rocky peaks". The lake is drained from the Maglic, the Volujak, and the Bioc hill ranges. The north side of the lake, which is open, has the wooded Vratnice. The lake water is green-blue. The plan is to form another national park within the borders of Montenegro, which should protect rest of the mountain range of Magilć-Volujak-Bioč and Trnovačko Lake. These two parks in neighboring countries should form one large transboundary protection zone.
