Mastnice

Mastnice is a small nature monument in South Bohemia, Czech Republic, protecting a wetland section of the stream valley that shares its name, roughly 1.25 km south of the village of Žitná, part of the Hracholusky municipality in the Prachatice district. Sitting at an elevation of 509–520 metres, the protected area covers just 1.14 hectares, making it one of the smaller yet botanically significant sites in the region.

Why was this area protected?

The nature monument covers a narrow, waterlogged stretch of the Mastnice stream valley together with alder stands and wet sedge meadows. Protection status was granted on 4 March 1988 by the former Prachatice District National Committee, and the site is classified under IUCN Category IV, meaning it is managed primarily to conserve specific species or habitats.

What can visitors see here?

The main reason for the site's protection is the presence of spring snowflake, a strongly endangered bulbous plant that carpets the wet meadows in the middle part of the valley with white blossoms in early spring. Alongside it grow other species typical of riparian meadow and floodplain habitats, including bird cherry, European spindle tree, and mezereum — a toxic shrub prized for its early, fragrant flowering.

The mix of wet meadows and alder thickets creates a mosaic of habitats favourable to a variety of insects. Butterflies associated with forest-meadow environments have been recorded here, along with beetle species adapted to boggy conditions.

When is the best time to visit?

Early spring is by far the most rewarding season, when the spring snowflake blooms — typically around late March to early April, though the exact timing depends on the year's weather. In summer, the site takes on a quieter character, presenting itself as a calm, green stream valley bordered by meadows.

How to get there?

Mastnice lies a short distance from the village of Žitná, part of the Hracholusky municipality in the Prachatice district of South Bohemia. The area has no dedicated tourist infrastructure — there are no parking areas or marked trails built specifically for this nature monument, so it is best treated as a stop along a broader hike through the Prachaticko region rather than a standalone destination.
