Sweden is split in two when it comes to ground preparation. In the north it is done mostly with mounding; in the south with trenching. Both methods have their advantages but the decisive factor is not latitude but rather the quality of the ground.
That is why Bracke Forest decided to demonstrate the advantages of mounding when forest owners in the south of the country attended this year’s big industry gathering, SkogsElmia.
It turned out that the method, which no less a personage than the 18th-century Swedish scientist Carl Linnaeus recommended back in his day, has its advocates even down in the south. The majority of those present knew what mounding is and how it works, even though one visitor guessed that the mounding head on show was a stump puller.
“Seventy-five percent of Sweden’s forest land is suitable for mounding,” Ekberg says.
The method involves turning pieces of turf upside down with the mounding head and then planting the new seedlings in the turf. On the right type of ground, the raised position in a mound gives the seedlings better growing conditions and also reduces the growth of deciduous trees in the replanted areas.
Bracke Forest says that mounding is not a general solution for forest owners. On some types of ground, trenching works better. What is important is to select the best method for each individual situation.
