Muddus (Swedish: [ˈmɵ̌dːɵs]; Lule Sami: Muttos) is a national park in northern Sweden.

Furthermore, it belongs to the largely untouched UNESCO World Heritage classified Laponian area.

Forest fires in Muddus National Park have left traces on sample plots.

[5] It is known for its waterfalls, deep ravines, low mountain and forest where the trees have seen many generations of people pass by.

Birds control the effects of patch size, forest age and tree species compositions.

Other animals that reside in the park are whooper swans, bean geese and black-throated loons appear on the lakes.

This is due to the abundance of spruce, pine forest, and shallow lakes in the northern taiga zone.
