The mountain falls within the Balkan mixed forests and Dinaric Mountains mixed forests terrestrial ecoregions of the Palearctic Temperate broadleaf and mixed forest. The slopes of the mountain is entirely covered with coniferous forests. It has thick vegetation of pines and beeches on high altitude, but sparse vegetation on the foot of the mountain due to the now closed plant that emitted harmful gases for the vegetation close to it. Gjallica appears to be very tall because the Black Drin valley to its west is only above sea level.
