The paper presents the results of a stand structure analysis of open Picea abies stand in the area called Židovský les (Jewish forest). This area was strongly influenced by human activities in the past. The virgin forest was cut clear in the middle of the 19th century, and after that the locality was used for cattle grazing and blueberry picking. In the second half of the 20th century, the most opened stands were partly underplanted. Besides the mentioned interventions, the area has remained relatively untouched since World War II. Some authors, consequently, compare the Jewish forest with the non-intervention management areas established after the bark beetle outbreak. The forest structure and natural regeneration were analysed on 10 research plots (50 m × 50 m). According to the results, three main structure types have originated after the disturbance. A dense multi-layered structure has been developed in waterlogged forests, multi-layered open stands have been found around the summit of the Medvědí hora Mt. and on the western slopes. Uniform stands occur on the northern and eastern slopes. Generally, compared with forests in non-intervention management areas, the stands of the Jewish forest differ in low density of trees, absence or lack of deadwood and low density of natural tree-species regeneration.
