The data used came from a regional forest inventory of the University Forest Enterprise "Kostelec nad Černými lesy", Czech Republic. The inventory was performed from 2009 to 2011 on 1,188 sample plots that represented 86 strata defined by the combination of three variables: site (5 categories), age (12 categories) and canopy cover (5 categories). On each sample plot, we quantified 171 partial biodiversity indicators that represented species or structural diversity. The quality of timber production was specified by four indicators quantified using local assortment tables. In total, we analysed 58,824 univariate linear regressions describing the relationships between diversity indicators and timber quality in individual strata. The results revealed that their relationship changes with stand age. The proportion of the best-quality assortments increases with the increasing species richness in all age categories.

A comparative study was done between in vitro rooting method and ex vitro rooting method. Using the ex vitro rooting method a plantlet could be produced in 135 days, which was in a shorter time compared to the in vitro rooting method - 180 days. The best axillary shoot bud induction was observed on Murashige and Skoog (MS) medium supplemented with 4.6 μM thidiazuron (TDZ) with 5 shoot buds per explant. In the shoot cluster, which was subcultured on MS medium supplemented with 2.3 μM TDZ, the rate of shoot multiplication increased in the 3rd subculture. The maximum mean number of shoots per explant (20) was obtained at the 3rd subculture on the same medium. Shoots were harvested at the 1st, 3rd and 5th subculture and pulse treated for root induction. The highest rooting (95%) was achieved from the 3rd subculture onwards with pulse treated shoots for fifteen days. The rooted plants could be established in a greenhouse with 99% survival. Ex vitro rooting is a promising method to reduce the time for plant generation. The resultant plantlets well established in pots and fruiting was observed within a year.

The evaluation stems from the results of economic analyses of enterprises that are further monitored in the context of forestry and development of economic financial ratios of evaluated companies. Furthermore, the evaluation is based on real possibilities of companies stemming from resources which they have at their disposal and on the facts that occurred in the selected companies in the monitored period. The development of important factors influencing the whole branch of forestry and their real state are introduced in the first part of the paper. After that, methods used in financial analysis of enterprises are described. The fact that forest land in the Czech Republic covered 2.66 million hectares in 2014 and its proportion in the total area of the country is 34% adds importance to the topic (Czech Statistical Yearbook 2015).

However, slow growth during early establishment, coupled with poor soil fertility, poses challenges for promoting tree planting programs. Field trials were undertaken on agroforestry land in Thailand to examine the efficacy of reforestation treatments. The first trial examined the effect of applying microorganisms and fertiliser on directly seeded Acacia mangium Willdenow, Dalbergia cochinchinensis Pierre and Xylia xylocarpa (Roxburgh) Theobald. After 20 months, a mixed inoculum of arbuscular mycorrhizal and ectomycorrhizal fungi improved survival and basal diameter of D. cochinchinensis by 15 and 43%, respectively. The co-inoculation of arbuscular mycorrhizal fungi and N2-fixing bacteria improved survival by 17%. The second trial investigated the effects of fertiliser and a water retention polymer on directly seeded A. mangium, Afzelia xylocarpa (Kurz) Craib, D. cochinchinensis, Eucalyptus camaldulensis Dehnhardt, Sindora cochinchinensis Baillon and X. xylocarpa. Height was improved by 40% at 20 months. Our findings suggest that reforestation is viable, provided that suitable treatments are used. These principles can be applied for reforestation of nutrient-impoverished soils of continental Southeast Asia.

A great potential of ALS lies in providing quick high precision data acquisition for purposes such as measurements of stand attributes over large forested areas. Models were developed using an area-based approach to predict forest variables such as wood volume and basal area. The solution was performed through developing an object-oriented script using Python programming language, Python Data Analysis Library (Pandas), which represents a very flexible and powerful data analysis tool in conjunction with interactive computational environment the IPython Notebook. Several regression models for estimation of forest inventory attributes were developed at a plot level.
