Značajni krajobraz Risovac - Grabovača kraj Perušića u Lici geomorfološki i speleološki je interesantno područje s brojnim estetskim, znanstvenim i obrazovnim vrijednostima. U sklopu projekta temeljnih geomorfoloških i speleoloških istraživanja, bez kojih nije moguće kvalitetno vrednovati georaznolikost i geobaštinu, korištene su morfometrijske i morfogenetske metode te metode speleoloških istraživanja. Cilj istraživanja bio je inventarizirati i analizirati geomorfološke pojave i procese u postupku ocjene stanja te kao polazište za vrednovanje radi kvalitetnog upravljanja i zaštite geobaštine. Temeljem hipsometrijskih odnosa izdvojene su morfografske reljefne cjeline. Definirane su i glavne morfostrukturne cjeline. Na istraživanom području prevladavaju krški i fluviokrški reljef s brojnim površinskim i podzemnim reljefnim oblicima. Brojni su i elementi antropogenog reljefa. Od reljefnih oblika detaljnije su analizirane ponikve i speleološki objekti kao najbrojnije i najinteresantnije pojave velikog geoturističkog potencijala.The Significant landscape Risovac - Grabovača near Perušić in Lika is a geomorphologically and speleologically interesting area with numerous aesthetic, scientific and educational values. As part of the project of basic geomorphological and speleological research, without which it is not possible to qualitatively evaluate geodiversity and geoheritage, morphometric and morphogenetic methods and methods of speleological research were used. The aim of the research was to inventory and analyze geomorphological phenomena and processes within the condition assessment and as a starting point for evaluation for quality management and protection of geoheritage. Based on hypsometric relationships, morphographic relief units were singled out. The main morphostructural units are also defined. Karst and fluviokarst relief with numerous surface and underground relief forms prevails in the investigated area. There are also numerous elements of anthropogenic relief. The dolines and caves as the most numerous and most interesting phenomena of great geotourism potential have been analyzed in more detail
