The sand pits of Veselí nad Lužnicí

  • First day

  • Location : Veselí nad Lužnicí

  • Trail

  • Results

First day

  • The sand pits were created by sand exploitation in this area in the eighties of the 20th centrury.

  • Even though this explotation is a perfect example of harsh intervention of man to the landscape, a unique ecosystem was created by natural recultivation. On the 1st day we had an opportunity to get acquainted with this ecosystem.

Location: Veselí nad Lužnicí

  • You are now standing in front of the sand pits . This location is situated in the Třeboňsko protected lanscape area and biospere reserve, between the town of Veselí nad Lužnicí and the villages of Horusice and Vlkov.


  • About the hiking trail.

  • The circular trail that starts here has 14 halts and it is approximately 7 km long.

  • There are certain rules,

  • that every visitor must obey:

  • it is prohibited to damage

  • the information tables,

  • pick flowers, disturb animals,

  • leave garbage behind and

  • camp free or make fires.


  • The exploitation of ballastsand in this area represents the intervention of human activity to the landscape. The flooded sand-pit = water ecosystem was created by soaking of subterranian water to the newly created pits after the exploitation. This water ecosystem is inhabited by rare flora and fauna.

  • Now the main problem is outdoor recreation (trash,noise).

  • Management of the Protected Landscape Area Třeboňsko regulate outdoor recreation, therefore pedestrian path was created.

  • The pedestrian path is intended for ecological pedagogy.


  • 5 sandpits – Veselské pískovny

  • Human created ecosystem

Drosera rotundifolia

  • Habitat:

    • wetland
    • poor nutrient soil
    • sunny places


Teesdalia nudicaulis

  • Asia and Europe

Chiffchaff (Phylloscopus collybita)

  • significant song

  • common in Europe and Asia

other typical birds

  • bluethroat (Luscinia svecica)

kingfisher (Alcedo atthis)

  • kingfisher (Alcedo atthis)


On the second day ( 3rd June 2008 ) we had an excursion to Protected Landscape Area Trebonsko.

Landscape attributes:

  • Třeboňsko is one of few Czech PLAs designated in a flat landscape that has been influenced by man for hundreds of years. Despite this, exceptionally significant natural treasures have been preserved here. A large part of the area  is formed by a balanced landscape where human activity is in harmony with nature. Třeboňsko was therefore designated one of six Czech UNESCO MAB biospheric reserves in 1977.

  • Two wetlands (Třeboňské Rybníky and Třeboňská Rašeliniště) of international significance, protected by the Ramsar convention have been designated here.

  • The area is significant with regard to the conservation of a range of endangered vulnerable vertebrates, for example lutra lutra (otter) and Haliaeetus albicilla (white-tailed eagle).

Our programme

  • We visited the best valuable bird area in the CHKO Třeboňsko – Nadějská complex lakes, lake Kaňov, Svět.

  • We could see more kinds of water birds and colonies of Grey Heron and Cormorant. As was said by Dr. Ševčík (our guid from the management of CHKO) the number of fish-consuming bird species, in the other species the number decreases or it is stabilized.

Observed kinds of birds

Observing in the countryside…

Bird ringing

  • An ornitologist showed us catching and ringing

  • We caught 11 birds:

    • 1 x Bluethroat (Luscinia svecica)
    • 10 x Swallows (Hirundo rustica)
    • Three birds had already had rings. We sent „equipment status monitoring „ for the National Museum in Prague.

The marker points to the featherless belly of Hirundo rustica . It is a proof that the famale is sitting on eggs.

The breeding station The third day

  • Anas platyrhynchos (Mallard, Stockente, Kachna divoká),

  • Phasianus colchicus (Pheasant, Fasan, Bažant obojkový)

Phasianus colchicus

  • Its origin is in Caucasus, introduced to Bohemia in the 15th Century

  • Foods: seeds and some kind of insects – they are useful for reducing insect pests

  • They have 8-16 chicks.

  • Have strong sexual dimorphism

Anas platyrhynchos

  • It’s a worldwide expanded species

  • Have strong sexual dimorphism

  • They have 8-13 chicks

  • They live near water

The breeding station

  • In the area of the breeding station there is also a hunters´ cottage. We could see a prepared head of Elk, that was struck by car. The Elks are stricktly protected in Czech Republic!

  • In the area there is a very interesting hatchery. In the time of our visit two small Mallards got incubated. We could also see a group of grown Mallards and Pheasants.In aviary there were some adult birds too.

  • Mallards and Pheasants are breeded mainly for hunting and as food.
