Research interests

My research focuses on the relationship between grazing, forest regeneration and forest damage. My area of ​​expertise is the management of ungulates and their forage resources in relation to land use. Ungulate species such as moose and roe deer affect the regeneration of trees and thus the composition of trees in the forest. A hard grazing pressure can lead to forest damages and thus long-term impacts on forest productivity. With their browsing selection on tree species like rowan, aspen and oak, ungulate species shape the habitat of other species that dependent on older trees. Ungulates like deer species are important game, and also become an increasing tourist value. With my research, I study the effects of ungulate browsing for the regrowth and re-establishment of trees, animals' forage preferences, and the relationship between browsing, forestry, forage quality and quantity.

1. Research program Forest and Wildlife: Opportunities for forest management to create forage to control grazing pressure and minimize forest damage
How do we manage the forest to minimize forest damage by ungulates? With careful management, we can maintain a high level of forestry, creating forage for ungulates while minimizing browsing on pine and other tree species. The program is a collaboration between the forest industry, the government, and SLU.

2. Monitoring of wildlife
We monitor continuously the development of wildlife populations (moose, roe deer, red and fallow deer, and wild boar) and their impact on the landscape using surveys of pellet counts, browsing pressure, and forest damage. The focus is on the south of Sweden where we have the most species of deer. The surveys provide basic data for improving the management of these different ungulate species.
