Together we help protect the ground squirrel

For winemakers

Winemakers - do you have sousliks in your vineyard? Be proud of them - it‘s a real rarity! Sousliks are considered one of the most endangered mammals in Europe. Help us, we can protect them together. We created the trademark Sysli na Vinici for winemakers who maintain their vineyards with sousliks in mind.

The trademark is awarded by ALKA Wildlife, o.p.s. and Karlovy Vary Museum who are conducting research on sousliks in the Czech Republic.


A trademark can be obtained for a vineyard which:

  1. Can prove occurrence of sousliks living within the vineyard for the given grape year
  2. The vineyard is maintained in a way that is both souslik and environmentally friendly.

Specifically, the minimum requirements for this are:

- At least every second row of the vineyard is grassed and

- The viticulturist tolerates the sousliks and does not use pesticides such as rodenticides

Here you can find a list of vineyards where sousliks have been confirmed and the award has been given.

If you would like to obtain the Sysli na Vinci trademark and display the stickers on your bottles, at your cellar and provide information leaflets to display and distribute to members of the public, please get in contact. You can also discuss reporting sightings of sousliks as well.

Advice for winemakers in how to support souslik populations in their vineyards and suggestions for winemakers who want to adapt their vineyards into suitable environments for sousliks.
