Karst areas are generally dry land with thin soil and limited surface water availability, yet they are widely used by communities for goat farming. The availability of forage is a determining factor for the success of such enterprises. This study aimed to examine the potential of karst land as a source of goat forage through the identification of the diversity, productivity, and quality of indigenous forage, as well as the estimation of livestock carrying capacity. The study was conducted using a survey method in the Southern Gombong Karst Mountains using vegetation analysis on sample plots, along with sampling for forage production and quality analysis. Observed variables were the types and groups of forage, fresh and dry matter production, crude protein and crude fiber contents, and livestock carrying capacity. Data were analyzed descriptively. The results showed that karst land has a diversity of indigenous forage consisting of grasses, legumes, and fodder trees, with dry matter production of about 3,500 kg/ha/year. The crude protein content of the legume and tree groups was relatively high (18–22%). The estimated carrying capacity of karst land reached about 5 goats/ha/year. It is concluded that karst land has potential as a source of goat forage, with opportunities to increase productivity through the introduction of tree legumes adaptive to dry land conditions.
