Methodology to rodent bark damage assessment on forest regeneration
Homolka, Miloslav ; Zejda, Jan ; Heroldová, Marta ; Kamler, Jiří
This methodology provides us with instructions, how to estimate extent of bark damage by gnawing caused by rodents on forest plantings based on a simple criterions. Data obtained may be used for objective assessment of rodent origin tree damage extent and its total value calculation. Exact data on tree damage can be used as a back coupling for damage prevention effectiveness. Relation between the rodent damage prevention costs and damaged area replanting costs may be retrospectively considered.

Methodology to rodent species density monitoring in forest environment
Homolka, Miloslav ; Zejda, Jan ; Heroldová, Marta ; Kamler, Jiří
This methodology provides us with instruction how to monitor rodent densities in forest environment and is concentrated on the species causing damage to broad-leaved forest plantings. Principle presumption for effective plantings protection control is to know rodent’s population density. Basic ecological informations about the target species are also included. This methodology book contribute to better understanding of young tree damage origin in broader connections and contribute to more effective input on damage prevention. Methodology is addressed above all to forest practices workers.
