Abstract
Tree encroachment and abandonment of pastures is an important cause of biodiversity loss in Sweden. In thisstudy, we evaluate the impact of all-year-around grazing by an ancient horse breed, the Gotland russ (GR),on tree encroachment. Twelve GR stallions were kept in 3 enclosures (lat: 59, long: 17, 4 GR/enclosure, 7ha forest and 3 ha open fields/enclosure) from May 2014 (age 1 yrs) until February 2016. Prior to the study,3 exclosures (EX, 5×42.5 m) where GR grazing was excluded were centered with the long side at the borderbetween forest and field. The field part of EX were further divided into four 5×5 m sections starting from theforest (1 to 4). Tree type (deciduous, spruce or pine), number and height were registered in the sections and theequivalent, grazed area adjacent to the EX on the 25th of February 2016. Body condition (BC) was assessedweekly using a 9 leveled scoring system. Individuals 4. Analysis of tree heights and numbers were made by procGLM in SAS. There was no difference in the totalnumber of deciduous trees (21±8 vs 25±8), spruces (2±1 vs 3±1) and pines (0.2±0.2 vs 0.8±0.2) between EXand grazed areas (P>0.05). In the grazed areas, the deciduous trees were shorter compared to the trees in EX(330±57 vs 780±70 mm, P
