This territory was established to protect the rare tree specie in Latvia - common hornbeam, which covers approximately 4% of the territory, but the most visually interesting part of the area is the Tīrspurvs swamp, also known as the Dunika heath. This is where the visitor will find Latvia’s longest and most impressive swamp footpaths, which crosses the area from the North to the South. Visitors will be fascinated by the unique landscape of the central part of the swamp, where in some places there are not even small swamp pine trees. Various habitats will be found – small swamp lakes, mineral islands, marsh pools, etc., and that is to say nothing of all the birds in the area.
