Hodnocení zdravotního stavu týku (Tectona grandis) na plantáži v podmínkách suchých tropů v Nikaragui
 Boltižiar, Martin
The goal of this project was to inventory control the health and the quality of Teak (Tectona grandis) stands on a tree farm in Nicaragua. There have been examined rows in lotes (stands) and measured following conditions: the health condition of a tree, microorganisms on the tree, cross-grain of wood, sapless tree, double stem and doddered top. The second part of the project has been done on experimental areas where all the trees were inventoried in every row. With collected data percentages were calculated for all observed attributes. From the results of the work we can tell the plantation still has a potential to grow stands of good quality.

Vliv různé intenzity probírky na přírůst v porostech týku (Tectona grandis) založeného ve sponu 1 x 1 m
 Hricko, Tomáš
The aim of this work was to find out the effect of three different cultivation interventions on teak forest (Tectona grandis) based on Nicaragua plantations in an unusual spacing 1x1m and to determine which of these interventions have the best influence in terms of the growth of wood mass and consequent mechanical stability of the overgrown stands. A height and thickness measurement of trees in the area of interest was carried out in 2014-2017. It was always a series of three types of thinning (schematic with 75% reduction, schematic combination with positive selection with 45% reduction and individual negative trench with about 55% reduction, one control area was left without intervention) in three replicates for stands based on years 2006, 2007 and 2008. According to our results, the best intervention is those with 75 % of reduction.

Hodnocení růstu mahagonu (Swietenia humilis Zucc.) na lesnické farmě HFC a.s., Nikaragua
 Mílová, Lucie
Bachelor thesis focuses on evaluation of growth of Sweettenia humilis Zucc. on the HFC a.s. forest farm, La Reserva, Nicaragua. Growth parameters were height and girth. During the planting, four restoration biotechnologies were used. It was plantinting on clear-cut area, planting under inclined secondary forest and plantings mixed with Tectona grandis, respectively with Gmelina arborea. The result is that the heights were the highest in mixed stand with teak (528 cm) and the biggest girth were on the open space (22.5 cm).
