Since Twente's economy is to a great extent reliant on agriculture, this leaves its marks on the landscape, with many meadows and pastures, alternating with undergrowth, scrubs and copse. There are several fens, marshes and peat bogs, which long made Twente less accessible for the rest of the Netherlands, and which formed some natural defence. It also made the inhabitants of Twente incline towards the east (Westphalia and Münster, more precisely) in trade, politics and fashion, rather than to the more western parts of the Netherlands.
