Abstract
Örups almskog has been described several times over the past 300 years. The forest has been a protected area since 1928, and when the aggressive strain of Dutch elm disease struck the region in 1979, it affected the forest in Örup for decades to come. Elms was the dominant tree species in the forest, and Dutch elm disease resulted in a high mortality for the elms. In Sweden Dutch elm disease was fought during the 1980s, but in Örup the authorities decided to let nature have its own course. This study took place in 1996 and focuses on the changes in tree and bush layers in the forest area as well as the changes that appear in the vascular plant society (species and amounts) as a result of the changing conditions.

Örups almskog has been described several times over the past 300 years.

Elms was the dominant tree species in the forest, and Dutch elm disease resulted in a high mortality for the elms. In Sweden Dutch elm disease was fought during the 1980s, but in Örup the authorities decided to let nature have its own course. This study took place in 1996 and focuses on the changes in tree and bush layers in the forest area as well as the changes that appear in the vascular plant society (species and amounts) as a result of the changing conditions. I replicated studies that were conducted by Claes Bergendorff 1980-1986 on vascular plant and plantsocietes (Hult-Sernander –Du Rietz) and most of his study of trees and bushes in a permanent 0,36 acer plot. I also conducted a study in the area with nearest tree method to get an overview of the composition of species and dead wood. I concluded that the elms keep on reproducing, and elm is still the dominant tree species in Örup, but the age structure is quite different with many young trees. The field layer changed when the older trees died and resulted in new circumstances with more light and richer soil, but after seventeen years there was a new canopy and much of the field layer returned to its original state.
