Thanks to their support everyone in the Netherlands can enjoy the alternating nature we have in this country. The Veluweloop goes right through one of the prettiest nature reserves of the Netherlands: National Park Veluwezoom and the IJsselvallei. Beautifull nature that gives you the opportunity to cycle and challenge yourself. Nature lets you live. That's why Natuurmonumenten protects and reinforces nature in the Netherlands. Like wild flowers. Flowers give color to our land scape. But where did they go? On meadows, floodplains or arable fields, you rarely find wild flowers. With the dissapearance of flowers, also insects dissapeared. Flowers are an important piece of the cycle of nature. If flowers dissapear, it results in a disaster. For all nature (not only for insects) ánd for humans, because land without flowers is ache and colorless. That's why we make space for wild flowers in verges, gardens, dikes, along arable land and in the meadow. That's how we make the land scape flourish and how we make the Netherlands beautifull. Also in National Park Veluwezoom and the IJsselvallei.Join too, give the Netherlands color and donate your deposit!"
