The study presents the assessment of forest curricula in terms of their content related to recreational use of forests based on the opinions expressed by the graduates of secondary schools and universities that are employed in the State Forests National Forest Holding. The e−mail survey was conducted in a group of 386 randomly selected employees of the State Forests representing regional directorates in Białystok, Katowice, Krosno, Radom, Warszawa and Zielona Góra. Analyses took into account exclusively the responses provided by graduates of secondary and higher schools of forestry (n=362). In order to examine whether there were statistically significant differences between the responses provided by those who completed secondary schools (SS) versus higher education (HE), the findings were subjected to Χ² test. This method was also used to find out if there were age−related differences in the responses. The results show that, regardless of the type of the completed school of forestry (SS – 14%, HE – 86%) vast majority of the graduates thought that the knowledge related to recreational use of forests which they had acquired in course of education was insufficient (61% for SS, 64% for HE) or indeed non−existent (6 and 8% respectively). The results show no statistically significant differences between the responses relative to the type of completed school (Χ²=0.9813, df=2, p=0.05) or the respondent age (Χ²=12.7462, df=8, p=0.05). The findings of the study support opinions related to the need of reforming curricula in schools of forestry at all the stages of education. The level of knowledge related to the recreational use of forests contained in the curricula of schools of forestry was assessed similarly, regardless of the graduates' age. Despite the more and more extensive research into forest−based recreation, and the growing interest of the public in this type of leisure, for four decades the curricula have not been visibly amended to include the relevant contents. Given the above, forest science curricula, both at the secondary and university level, should be supplemented as soon as possible with issues related to recreational use of forests.
W artykule przedstawiono wyniki przeprowadzonych badań porównawczych - w zakresie osiąganej wydajności - technologii zrywki drewna długiego i krótkiego w przedrębnych lasach górskich. Badaniom poddano technologie najczęściej stosowane w górskim gospodarstwie leśnym w Polsce.
W artykule przedstawiono wyniki przeprowadzonych badań porównawczych - w zakresie osiąganej efektywności - technologii zrywki drewna krótkiego w lasach górskich. Badania przeprowadzono w oparciu o środki zrywkowe stosowane powszechnie w lasach górskich Polski (specjalistyczny leśny ciągnik przegubowy typu skider, zaprzęg konny, ciągnik rolniczy).

The study was designed to determine current recreational value of the state forests in Poland from the viewpoint of their administrator (i.e. the State Forests National Forest Holding) and to compare this findings with the value estimated by other researchers. The research was conducted in 31% of all the forest districts administered by the State Forests. The survey was sent to these units by e−mail. It contained two questions about: (1) what part of the total annual expenditures of the forest district is connected with recreational development and use of forests, and (2) what part of the total annual revenues of the forest district is generated by recreational use of forests. Afterwards, the current recreational value of the State Forests was calculated. Budget related data come from the annual financial and operational statement of the State Forests. The findings show that operations linked with recreational use of forests in majority of the forest districts generate losses and only in some of them measurable financial gains are recorded. Costs linked to recreational use of forests are incurred by nearly all districts (97%), yet in the most cases they account for up to 3% of the total disbursements. Only 25% of the forest districts recorded revenues from this type of operations. The current recreational value of the State Forests in Poland is estimated to circa 8 USD/ha. Notably, this is a mean value for all national forests in Poland, yet not all of them are equally attractive to visitors. The relevant value for only urban and suburban forests equals 94 USD/ha, which is approximately 10% of the estimated value reported by other researchers. It can be assumed that the remaining part of the revenues generated by recreational function of forests represent earnings of local businesses (accommodation, catering, grocery shops, souvenirs, transport and other services). The present findings provide important information for the State Forest administrators and for the public. Forest administrators should seek the possibility to change above mentioned disadvantageous ratio to at least one of 3:7. Given this, a change in the national forest policy would be worth considering; a proposal for such transformation is presented.

The article presents the recreational potential of the forests within the Magurski National Park (MNP) and compares it with the actual number of visitors. The study examined 218 forest units comprising in total of 8653 ha, which accounts for 47% of the Park forest area. Forestation rate in the area amounts to 95%. Mean recreational capacity of the forests within the examined part of the MNP was 1.93 man− hour/ha/day, yielding 29 persons/ha/year, while the actual number of tourists of 2.35 persons/ha/year. The findings show the recreational potential of the Magurski National Park is used at the low level.
W pracy dokonano porównania technologii zrywki drewna stosowanych powszechnie w rębnych lasach górskich Polski pod kątem ich oddziaływania na poszczególne komponenty krajobrazu leśnego. Określono ich oddziaływanie na glebę, nalot i podrost oraz drzewa pozostające w drzewostanie po cięciach. Badania wykazały, że odpowiedni dobór technologii zrywki może przyczynić się do zmniejszenia negatywnego oddziaływania procesu pozyskiwania drewna na krajobraz leśny.
