Tajba, National nature reserve in Trebišov district, Slovakia

Tajba is a nature reserve in the Trebišov district that protects a bend in the Bodrog River with wetland vegetation covering about 27 hectares. The reserve contains shallow waters, reed beds, and floodplain forests that provide habitat for water-dependent animals.

The reserve was established in 1966 to protect a specific turtle species from extinction. This action represented an important step in conservation efforts within the country.

The European pond turtle is the reserve's flagship species, with a social value set at 3,000 euros in Slovakia. Since 2019 warning road signs reading "korytnačka močiarna" alert drivers to turtles crossing between Tajba and the Somotor canal. Volunteers and CHKO Latorica staff clear invasive acacia, dogwood, blackthorn and goldenrod from the egg-laying sites.

Access to certain sections requires prior permission from the reserve management to protect sensitive habitats. Visitors should check in advance which areas are open and wear sturdy shoes since the terrain can be muddy and wet.

In 1986 Jozef Voskár counted five adults of 20–25 cm about 20 m apart along a 150 m stretch, plus smaller turtles, in sections untouched by the oil spill. Nationwide reports to the European Commission for 2013–2018 put the Slovak population at 300–500 individuals, declining. Warning road signs for migrating turtles were installed in 2019.
