Hodnocení základních prvků srážko-odtokového procesu vybraného lesního mikropovodí na území ŠLP ML Křtiny
Šteflová, Gabriela
The thesis is focused on the evaluation of rainfall-runoff process on three stabilized micro-watersheds with different tree species in forest stand, which cover spruce, beech and mixed forest stand, located in the uplands. River basin has been investigated under the same climatic conditions during the growing season 2015. Examined micro-watersheds is located in the FTE Křtiny. This thesis include evaluation of basic statistical parameters and assessment of extreme event for particular watersheds. The work also includes a literature review on the topic parameterization rainfall-runoff process and a description of the experimental watershed. The results indicate that the highest water management efficiency (best parameters of the runoff process)obtains a catchment area of beech stand, while the worst parametrs obtains the spruce watershed.
Možnosti eradikace nepůvodního a potenciálně invazivního druhu Calotropis procera na ostrově Sokotra
Šteflová, Gabriela
Calotropis procera, tree native in northern Africa and western and southern Asia, was introduced to Socotra for more than a century ago and is one of 87 non-native species of the local flora. Although in some places of the planet the species has invasive character, on Socotra it is not considered as dangerous. Especially in the north of the island near the capital Hadibo it is however abundantly represented in home gardens and could have an impact on local vegetation. During the field investigation, it has been found that as long as the vegetation of the island would be under intensive pressure of livestock, especially goats, Calotropis procera would not have invasive character outside fenced gardens. Mature individuals from the wild would be appropriate to reduce mechanically using common tools, mainly by cutting them because potential shoots would be rapidly eliminated by grazing.
