The sand martin (Riparia riparia) is an endangered swallow species that nests in colonies on steep and sandy slopes, such as sand pits and river banks. The nest is often a meter long cavity. The steepness of the slopes is an important factor so that small predators do not get near the nests.

The sand martin can be found in the whole country but it is most common in Lapland. The population has declined due to lack of nesting places.

In 2021, a former gravel pit wall has been cleared here to create a suitable nesting environment. We do not yet know, whether the demanding species will accept this area as its habitat. If we are lucky and it does, please do not disturb the species by going too close to the nests.
