Occurrence of certain microfungi on reindeer pastures in northern Finland during winter 1996-97
Thick snow covering on warm and unfrozen soil in late autumn is believed to promote mould growth on the winter pastures of reindeer. Natural feed containing potential mycotoxins is suggested to affect the condition and health of the reindeer. During this kind of winter and spring 1996-97 we collecte...

Thick snow covering on warm and unfrozen soil in late autumn is believed to promote mould growth on the winter pastures of reindeer. Natural feed containing potential mycotoxins is suggested to affect the condition and health of the reindeer. During this kind of winter and spring 1996-97 we collected 30 samples from winter forage plants on three winter ranges in nothern Finland. We identified altogethet 12 different species or species groups of fungi in plant samples.
