WEATHER CONDITIONS

Season phenology: early

Weather conditions:

Weather conditions were favourable for breeding with an early spring and warm summer, although some nests disappeared after heavy rains.

Season humidity: rainy

Date of final loss of snow:

BIOTIC CONDITIONS

Rodents abundance evaluation:

low

Breeding conditions:

Predators, both mammals and birds, then fed on bird eggs and chicks. As a result, breeding success of waders was close to zero. Little Stints had already started to concentrate in post-breeding flocks at the beginning of July. Such a low breeding success in the region had only been recorded previously in 1974.
 

Rodent dynamics:

Lemmings were numerous during spring, but then decreased sharply.

Rodent species recorded:
