Secondary succession and summer herbivory in a subarctic grassland: community structure and diversity
A field experiment was established in a subarctic grassland in the Finnish Lapland to study the role of summer herbivory in plant community succession Perennial vegetation and moss cover were removed in an area of 324 m 2 The site was divided into four blocks, of which two were fenced to prevent her...
