Description
How does nature recover after a forest fire? Which species find their way back to the fire-ravaged forest first? At what rate do tree species establish themselves? Researchers will hopefully find the answers to these questions in this nature reserve.
Oskarshamnsbrännan
Hammarsebo firefield is part of the so-called Oskarshamnsbrännan - a hard-to-extinguish fire that raged in the late summer of 1983. The fire provided a unique opportunity to study how nature recovers after a forest fire. As a result, a 65-hectare area was set aside as a nature reserve. But this was not the first time the forest had burned.
Wood burning and grazing
Researchers have studied charcoal residues in a bog in the area and found that fires were frequent and very long-standing. Many of the fires are probably the result of recurrent burning. Burning involved burning areas where, for example, sword rye could be grown. The forests were also burned to create better pasture for cattle.
First in place
In the first few years after the 1983 fire, many pioneer species appeared. For example, the rare plants sword fist and fire fist sprouted. Their seeds can lie dormant in the ground for up to a hundred years. So the seeds were already in place as a seed bank and were activated by the fire. Insects such as the fire borer and the lesser fire borer and birds such as the skylark and the tree pipit were also present early on.
Nature's way
Nature has now entered a new phase. Almost all the burnt, remaining forest from 1983 has died. Other species are now moving into the forest, especially those that need dead wood to live or forage. In the reserve, for example, as many as 240 beetle species have been found living on dead wood. That's a third of all Sweden's beetles linked to dead wood!
