Růst a prosperita výsadeb douglasky tisolisté na Opočensku

The aim of this diploma thesis is to assess the growth potential of Douglas fir (Pseudotsuga menziesii / Mirbel / Franco) compared to other agricultural tree species of the Czech Republic. Data collection took place on the plots located in the forests of Kristina Colloredo-Mansfeld's property in Opočensko. There were 2 areas where douglas were grown in various mixtures with pine, spruce, oak and beech. By evaluating the results for 5 years of observation, it was found that Douglas already has a demonstrably faster growth rate in the early stage of growth, and in some cases has 2.5 times higher production potential than most of our agricultural tree species. The benefit of this work is to demonstrate the potential production capacities of douglas and their positive benefits to our forestry, including resilience and ability to adapt to current climate change
