They belong to the sunken boulder Highlands of palaeogeological origin, rich in mineral resources (granite, and oil and gas).

The Moslavačka mountains are covered with dense forests of beech, sessile oak, hornbeam, chestnut, black alder and birch, and in the lower regions there are cultivated orchards and vineyards.

Rare and endangered plants that grow here include: star sedge (Carex echinata) and Lesser Butterfly-orchid (Platanthera bifolia).

In the watercourses live endangered fish such as the white chub (Leuciscus cavedanus), and amphibians include the fire Salamander, Agile Frog and Yellow-bellied toad.

In the Moslavačka Gora area, there are remains of ancient fortifications, of which the best known is Garić-grad, built by Ban Stjepan Šubić in 1256 AD.
