The study attempts to assess the strategic position of the forest service sector companies based on the SWOT method. Positioning of the company development was done on the example of 49 companies, which are providing services for the forest management in Poznań, Piła and Szczecin Regional State Forest Directorates (western Poland). Data that enabled the analysis was obtained by the usage of the questionnaire method. The structure analysis of the respondents from the point of view of points assigned to the investigated factors and assessments of these factors was performed. The results showed that the vast majority of companies that were participating in the research was on the average and aggressor developmental position. The internal factors such as ‘work experience of human resources', ‘machines technical quality' and external factor such as ‘forest services contract principle' were the most important for the forest companies owners. ‘Leasing of forest machines' and ‘opportunity for action as consortiums' are said to bring about strengths, while ‘purchase of machinery by the State Forest', ‘business ethics', ‘increase of fuel prices' and ‘new competing companies' are considered as the main threats.
Na podstawie badań własnych przeprowadzonych w latach 2000-2007 na terenie Lasów Pilskich (RDLP Piła) i danych literaturowych przedyskutowano problemy identyfikacji siedlisk Natura 2000 – zbiorników ramienicowych (3140) i dystroficznych (3160). Zwrócono uwagę na szeroki aspekt występowania ramienic oraz kryterium florystyczne, będące podstawą identyfikacji siedlisk 3140. W przypadku zbiorników dystroficznych (3160) stwierdzono, że podstawą identyfikacji winno być kryterium hydrochemiczne i stwierdzenie zachodzenia procesu dystrofizacji, jako warunku ich funkcjonowania. Kryterium florystyczne w dla identyfikacji zbiorników dystroficznych powinno mieć charakter jedynie wstępnej diagnozy. Na przykładach z Lasów Pilskich zaprezentowano klasyczne postaci omawianych siedlisk oraz trudniejsze do identyfikacji, podlegające alloiotrofizacji, jeziora ramienicowe otoczone torfowiskami mszarnymi. Zwrócono uwagę na rzadki przykład jeziora źródliskowego z przylegającymi mszarami. Podkreślono, że omawiane siedliska są ostojami cennych roślin Natura 2000 (jak Aldrovanda vesiculosa, Elisma natans, Liparis loeselii i Najas flexilis) oraz innych rzadkich w Polsce i regionie Lasów Pilskich.
The Sustainable Use Directive (2009/128/EC) establishes a framework for European Community action to achieve the sustainable use of pesticides imposed restrictions in agro−aviation pesticides application. As a result of the creation of buffer zones, part of the endangered area must be excluded from spraying and the area will be fragmented. This article evaluated the impact of the size, shape and distance between the sprayed area and the aerodrome, on the efficiency and cost of agro−aviation spraying in Regional Directorate of the State Forests in Piła (western Poland) in 2013. The efficiency of agro−aviation spraying is highly positively correlated with the shape and size of sprayed area. Weak negative correlation was found with the distance between the sprayed area and the aerodrome. The obtained efficiency ranged from 23.37 to 198.98 ha/h, while the costs covered the span from 61.96 to 423.34 zł/ha. The structure of unit costs varied depending on the spraying parameters. The costs of aircraft charter and purchase of pesticides are dominating part of the whole process. Variability of the spraying costs causes that their averaging distorts the results and makes it difficult to plan the future costs.
