the State Forests in Poland
Opis:
A growing need to lead a healthy lifestyle and to spend more time in nature causes an increased pressure on forests, which renders their social functions more and more important. In order to meet people’s expectations, the State Forests undertake several actions to make forests more available to the public including the organization of running events in forests and the development of a network of recreational and running paths. In order to describe these actions, an online survey was conducted among the workers of forest districts. Additional data such as information published on the State Forests’ website, Facebook and runners’ blogs, was included in the analysis as well. 283 forest districts participated in the electronic survey. The results indicate that the State Forests actively participated in promoting running events in forests totaling 488 running events in 2014 and 779 between January and October 2017, which constitutes an increase by approximately 60%. The average number of running events in the forest districts during the analyzed period was 9.5. Most of them took place in forest districts within city agglomerations and in the mountains. The State Forests supported over 20% of running events organized in the areas they administer. They had also started numerous initiatives (such as "Wolność w naturze", "Zielony punkt kontrolny" and "BiegamBoLubię Lasy") that were evaluated positively by their participants (according to Facebook). In conclusion, it is clear that the State Forests do promote recreation in forests and forest education by supporting public events.

Opis:
The aim of the study was to evaluate the area and volume of the windthrows caused by a downburst, which occurred early morning on July 8th , 2015 in the Międzylesie Forest District (south−western Poland). The wind velocity reached 270 km/h and the phenomenon caused damages similar to those observed after the hurricane. The most affected forest ranges included: Różanka, Nowa Wieś, Lesica, Goworów, Jodłów and Smreczyna. To evaluate the area of the windthrow in particular forest stands, the remote sensing data were used, whereas to estimate the total wood volume we applied the growth model and the average volume of the particular forest stands, gathered in the State Forests Information System (SILP) database. The volume of the windthrow evaluated by the forest rangers during some local investigation equaled 103 thousands m³, while one calculated using the SILP database – 161 thousands m³ and with the growth model – 168 thousands m³. The forest service estimations were underestimated. According to the model of the wind damage risk, most of the forest stands in the Międzylesie Forest District were highly or very highly endangered by the strong winds. The presence of the windtrhow is very dangerous either for people or the surrounding forest (due to the risk of pests outbreak). Therefore it demands immediate decisions and actions from the forest service, which need reliable and quickly accessible data. The information provided with the satellite imagery, the risk model and the growth model may accelerate the decision−making process and optimize the damage disposal. Satellite imagery also enables to estimate the amount of damage on the areas, which are hardly available for the foresters and their vehicles. Due to their high usefulness, growing availability and declining prices, these tools should be introduced to local forestry as quickly as possible.
