I´m on my third year as a PhD student and my topic is natural regeneration and management of birch in central and northern Sweden.


The share of deciduous species in the Swedish forest will probably increase in the future, due to higher requirements from certification schemes. The Forest stewardship council (FSC) requests that from october 1th 2020, the aim for all forest owners should be that all forests should hold at least 10% deciduous species, and that at least 5% of the mesic and moist land area is dominated by deciduous species (Forest Stewardship Council, 2020).

Since the birch (Betula pendula and Betula pubescens) are the only deciduous species in Sweden that are to some larger extent regenerating naturally, and since most other deciduous species are suffering from browsing, we are assuming that it is going to be the birch that are mixed into the conifer stands and stands dominated by birch that are saved to fulfill the certification requirements.

These birches are usually allocated to humid areas and areas with high incidence of rock in the surface which obstruct soil preparation. The idea is to allocate the birches to areas where it is difficult or expensive to  plant conifer seedlings, but at the same time there is a high probability of abundant spreads of naturally regenerated birch.

In order to adapt today's forestry to the new certification requirements, increased knowledge about the establishment and maintenance of naturally regenerated birch is required, this is what I am focusing on during my time as a PhD student.
