Forest management of alder stands on the ecological series L – riparian sites
Bačovský, Jan ; Šálek, Lubomír (advisor) ; Martinisko, Jakub (referee)
The diploma thesis was focused to forest management of alder stands on the groups of forest habitat types 3L and 1L aiming to enhancement of quality production. The stands are located in the forest ranges Býchory,Ledce and Nymburk.
On those localities alder is only marginal tree species even though according to the rule No. 84/96 Sb. about forest management planning alder belongs to the important soil improving and reinforcing tree species in several management sets of stands. While the stocking on the forest habita types 3L is insufficient in many cases the stocking on the forest habitat types 1L is optimal. . The stand 204 which is 41 years old, has stock volume 182,65 m3/ha, the stand 308 at the age of 39 years has stock volume 129,28 m3/ha. The stand 616 at the age of 72 years has stock volume 220,67 m3/ha and the stand 617 at the age of 72 years has stock volume 212,12 m3/ha.
The tending proposal presents the alder silviculture as the integral part of forest ecosystems in the given landscape for the future management. 511E7 vegetation at the age of 76 years old has a of 167,13 m3/ha. Vegetation 511J8 at age 90 has a vocabulary of 203,33 m3/ha. Vegetation 512D5 at the age of 58 years old has a vocabulary of 166,75 m3/ha. The tending proposal is aimed to improvement of the quality status of stands and to maintenance the alder in forest ranges as an integral part of the landscape.

Comparison of production and quality of one-story and two-story pine stands on acid soils on 3rd vegetation belt
Sýkora, Jan ; Šálek, Lubomír (advisor) ; Martinisko, Jakub (referee)
The diploma thesis deals with comparison of production of one-story and two-story pine stands on acid soils on 3rd vegetation belt. The thesis provides comparison between two different silvicultural methods for Scotch pine (Pinus sylvestris L.).
The study area was located in central Bohemia, in the Forest Natural Area Křivoklátsko. Investigated forest stands belong to the military forests run by Vojenské lesy a statky, s.p., division Hořovice, forestry office Nouzov.
Using circular sample plots the stock volume and mensuration characteristics were measured and calculated in individual stands. Evaluated characteristics of one-story and two-story stands were compared.
The most important result of the research is the fact that Scotch pine (Pinus sylvestris L.) reaches higher production and higher timber quality in the two-story stands.
