Häme is a region of great diversity. The degree of industrialization is high, and most of the major transport routes of Finland pass through the region. On the other hand, Häme is also a region of intensive agriculture and forestry.
Most of the Kanta-Häme subregion belongs to the drainage basins of the Kokemäenjoki and Vantaanjoki rivers, while the waters of the Päijät-Häme subregion mostly flow through the Kymijoki and Porvoonjoki rivers into the Gulf of Finland.
The three great terminal moraine formations of Finland, all of them known by the Finnish name Salpausselkä, extend through the region. There are also many esker chains. Because of these geological formations, Häme has unusually rich gravel, sand, and groundwater resources.
Häme's flora and fauna are also of great diversity and the spectrum of species and habitats is wide: from dry pine-dominated forests to lush deciduous forests, from large mires and lakes to small mosaics of rocky meadows.
The region is characterized by strong interaction between nature and culture, a rich archaeological heritage, and an extensive patchwork of various built environments and agricultural landscapes.
