Located in southeastern Europe, Moldova is bordered on the west by Romania and on the north, south, and east by Ukraine. Most of its territory lies between the area’s two main rivers, the Dniester and the Prut. The Dniester forms a small part of Moldova’s border with Ukraine in the northeast and southeast, but it mainly flows through the eastern part of the country, separating Bessarabia and Transnistria. The Prut River forms Moldova’s entire western boundary with Romania. The Danube touches the Moldovan border at its southernmost tip, and forms the border for 200 m (656 ft).
Phytogeographically, Moldova is shared between the Central European and Eastern European provinces of the Circumboreal Region within the Boreal Kingdom. According to the WWF, the territory of Moldova can be subdivided into three ecoregions: the Central European mixed forests, the East European forest steppe (the most territory of the country), and Pontic steppe (in the south and southeast).
