The paper analyses knowledge of secondary school pupils from Ustrzyki Dolne and tourists visiting the Bieszczady National Park. Both groups were surveyed in 2011−2012. Tourists and pupils were well−informed about the presence of brown bear in the Bieszczady (96%), but far less about its distribution in other mountain ranges. Nearly 30% of the questioned tourists were not aware of the fact that leaving...
Presence of four owl species was confirmed in the area of Forest Experimental Station of WULS−SGGW in Rogów (central Poland) at the beginning of the 2000s. These were tawny owl, long−eared owl, little owl and barn owl. In the second half of the XX century migratory short−eared owls had also been recorded. Density of tawny owl territories per total area was 2.6/10 km2. For long−eared owl it was lower...
Paper presents results of measurement accuracy evaluation of two laser rangefinders (TruPulse and ForestPro integrated with MapStar compass) mounted on monopod and tripod under the forest conditions. The precise data on spatial coordinates of 34 trees in the Rogów Arboretum and 8 points from the geodetic control network in the Głuchów Forest were used. The results show that the measurement sets equipped...
The goals of this study are (1) to analyse the accuracy of the approximation of empirical distributions of diameter at breast height (dbh) using two−component mixtures of either the Weibull distribution or the gamma distribution in two−cohort stands, and (2) to discuss the procedure of choosing goodness−of−fit tests. The study plots were located in the Świętokrzyski National Park (central Poland)...
Increment of growing stock is one of the key indicators useful in forest management. In the State Forests in Poland, up to now it is estimated using growth and yield tables elaborated a century ago. Paper presents results of study concerning current annual increment of Scots pine stands. Basing on repeated measurements of stand volume increment was estimated to 14.5 m3/ha for stands in age from 37...
Particular entities of the State Forests differ in their activity in the field of nature−and forest−related education. The study provides an economic evaluation of the degree of involvement of forest districts, within the Regional Directorate of State Forests (RDSF) in Kraków, in educating the society on nature− and forest−related issues. Financial expenditures were analysed and the zero unitarization...
Study presents a classification model for predicting the occurrence of mass damage in young forest plantations caused by insect pests on roots belonging to Melolontha genus. Logistic regression model was built on the basis of 10 taxation features describing 177 young stands. Habitat fertility, occurrence of Scots pine and European beech, and weed infestation of the habitat are the most significant...
In homogeneous climate conditions Scots pine trees at different sites have similar short−term incremental rhythm. It was determined by the temperature of early spring and precipitation in June. Differences in the growth pattern are caused by various sensitivities of pines from different habitats to the temperature in May and precipitation in February and April of the current year.
The paper compares direct economic and financial instruments used for promoting the multifunctional forest management in the Czech Republic (CR) and in Poland. In both countries subsidies are the most significant instruments of support. They come from the state budgets, the EU resources, as well as from public ecological funds. The other common instruments used are: compensations (CR), tax concessions,...
