The tundra vole is a good swimmer, winter inundation is therefore no problem. But there is a chance of drowning when their holes flood. Inundation outside the winter season can result in death of their young, as they cannot yet swim properly #5. |

Referentie: #4, #9 Please note that the vegetation information of the Volkerak-Zoommeer projects is derived from the water plant module (riverbank vegetation, HSI>0.5) and the ecotope map, as was used previously in the project 'Seizoensgebonden Peilen IJsselmeer' (only in Dutch). In addition, a vital population of 50 males and 100 females need a habitat of 75000m2 with suitable vegetation. Smaller areas can function as a temporary habitat #10. |
