vegetation and soil carbon-and nitrogen cycles in a grazing area through food selection, consumption, fertilization, and trampling. There have been discussions on how reindeer grazing, plant communities, and different ecosystems relate to each other and how the management of protected areas should proceed based on various laws, recommendations, and perspectives. The purpose of this study is to examine the impact of reindeer grazing on biodiversity in northern Scandinavia and thus be able to support these discussions. Inventory data was collected in 1995 on both sides of the fence that demarcates Norway from Malla National Park in Finland. At the time of the inventory, reindeer husbandry had been prohibited on the Finnish side of the fence for several decades, creating a difference in grazing pressure between the inventory areas. A statistical comparison was made between the number of plant species for six different functional plant groups divided into four different soil moisture types between the two countries, as well as a comparison of the number of reindeer droppings per study area in each country to quantify the difference in grazing pressure. The results show that there were more grass species in meadow areas and more reindeer droppings on the Norwegian side. I found no significant difference for the other functional plant groups or for the grasses in the other soil moisture types. Based on these results, I conclude that reindeer may increase the number of grass species in meadow areas.
