Biološka zbirka (JU Muzej istočne Bosne Tuzla)

Biološka zbirka, the Biological Collection of the Museum of East Bosnia in Tuzla, is a quiet gem for anyone interested in the region’s natural heritage. Rather than presenting nature as an abstract concept, the collection focuses on the living world of northeastern Bosnia—its forests, wetlands, mountains, and the species that define them. It’s a compact but carefully curated space that reveals how diverse Tuzla’s environment truly is. Inside, visitors can explore taxidermied specimens of native mammals and birds, including owls, foxes, and river‑dwelling species that once thrived around Tuzla’s salt springs. The insect collection is particularly engaging: colourful butterflies, beetles, and rare endemic species illustrate how micro‑habitats shape biodiversity. Detailed botanical samples show the plants typical of the region’s karst and forest landscapes, offering a close look at species that are often overlooked outdoors. One of the most interesting features is the educational focus. Many displays explain how industrialization, mining, and salt extraction influenced local ecosystems, making the collection not just a showcase of species but a story of environmental change.
