Utilization of old meadow by reindeer in spring in northern Norway
Utilization of abandoned coastal meadows in northern Norway by reindeer (Rangifer tarandus tarandus) were investigated for 25 days in spring 1996 (« = 12, 40-57 kg body mass (BM)) and 24 days in 1997 (» = 12, 39-61 kg BM). Grass production on grazed and ungrazed meadow was measured both years. Faeca...
