Adama Mickiewicza This report presents selected species of moths recorded during research conducted in the Wolin National Park in 2024, which are either rare in Poland or were reported for the first time in West Pomeranian (Zachodniopomorskie) voivodship. The species listed were caught in light traps and are housed in the auditors’ collections. The names, taxonomy and distribution were adopted from the Distributional Checklist of the Lepidoptera of Poland (Buszko and Nowacki, 2017). Species new to the West Pomeranian Voivodeship are marked with an asterisk next to the species name (*), while those confirmed from this area for the first time after an extensive interval are distinguished with two asterisks (**). https://www.forestry.actapol.net/volume24/issue1/1_1_2025.pdf Wolin National Park rare species Lepidoptera moths eng Poznan University of Life Sciences, Poland Acta Scientiarum Polonorum Silvarum Colendarum Ratio et Industria Lignaria 16440722 2025-03-30 24 1 article Włodzimierz Stempski 1 Michał Korzański 2 Katedra Ekonomiki i Techniki Leśnej, Uniwersytet Przyrodniczy w Poznaniu Nadleśnictwo Wolsztyn, Regionalna Dyrekcja Lasów Państwowych w Poznaniu The aim of the study was to analyse timber deliveries to two small recipients – one processed mainly medium-sized timber (plant), the other mainly large-sized timber (sawmill). The scope of the study included daily, weekly and monthly deliveries from two years, and hourly deliveries from one year. Data for the analysis was sourced from export receipts made available successively after each month by these recipients. Despite the greater number of assortments purchased by the plant (12, sawmill – 8), the share of deliveries of uniform assortments to this recipient was twice as large as to the sawmill. The structure of daily deliveries to the analysed recipients was practically the same, with the peak on Wednesdays and the smallest number on Mondays. Greater differences were found in monthly deliveries – the largest amount of timber was delivered to the plant in May and November, while to the sawmill in March and April and then in October and November. Minor differences were also found in the structure of the hourly deliveries, with two peaks characteristic for both recipients – one in the morning (9:00–9:59) and one at noon and in the early afternoon (12:00–12:59, 13:00–13:59). In the remaining hours, there were minor differences between the plant and the sawmill. https://www.forestry.actapol.net/volume24/issue1/2_1_2025.pdf wood recipient wood supply structure wood transport large-sized wood medium-sized wood eng Poznan University of Life Sciences, Poland Acta Scientiarum Polonorum Silvarum Colendarum Ratio et Industria Lignaria 16440722 2025-03-30 24 1 article Emilia Wysocka-Fijorek 1 Anna Głowacka 1 Instytut Badawczy Leśnictwa, Sękocin Stary The aim of the study was to draw attention to the fact that management of forest resources is subject to many constraints due to their social, natural and economic importance. All forest property owners have to be aware of the obligations incumbent upon them. Tasks that forest owners need to fulfil when managing a forest enterprise are listed in the Forest Act. As part of their responsibilities the district (Polish: powiat, i.e. county) official being the head of the district administration (Polish: starosta) has a number of powers in the supervision of forests that are not owned by the State Treasury. This primarily includes supervision over forest management in non-state forests. The most difficult task facing these district administration heads in connection with the supervision of forests is to assess whether owners are carrying out their activities in the forests in compliance with all their obligations. https://www.forestry.actapol.net/volume24/issue1/3_1_2025.pdf private forests wood forest protection small forest ownership legal basis eng Poznan University of Life Sciences, Poland Acta Scientiarum Polonorum Silvarum Colendarum Ratio et Industria Lignaria 16440722 2025-03-30 24 1 article Wojciech Szewczyk 1 Uniwersytet Przyrodniczy w Poznaniu, Wydział Leśny i Technologii Drewna, Katedra Entomologii i Fitopatologii Leśnej This study assessed the threat posed by the fungus Porodaedalea pini in selected residual Scots pine (Pinus sylvestris) stands in the Oborniki Forest District. Sixteen research plots were surveyed, with a total of 535 trees inventoried. A total of 22 fruiting bodies and 11 cavities were observed, while disease symptoms were found in only 14 trees (2.6%). The low number of infected trees indicates good phytosanitary condition of the surveyed stands; however, the affected trees exhibited high levels of defoliation.   https://www.forestry.actapol.net/volume24/issue1/4_1_2025.pdf Phellinus pini Scots pine residual trees white pocket rot defoliation red ring rot eng Poznan University of Life Sciences, Poland Acta Scientiarum Polonorum Silvarum Colendarum Ratio et Industria Lignaria 16440722 2025-03-30 24 1 article Artur Chrzanowski¹ 1 Miłosz Kardacz 1 Robert Kuźmiński¹ 1 Ryszard Chrzanowski 1 ¹Katedra Entomologii i Fitopatologii Leśnej, Uniwersytet Przyrodniczy w Poznaniu This study presents the first comprehensive inventory of saproxylic beetles in the Wolin National Park after World War II. Field research was conducted in 2024 using barrier, cross, and Moericke traps, as well as direct observations and laboratory cultures. The inventory identified a total of 45 species belonging to 16 families. These included taxa of high conservation value, including Stenagostus rufus (NT), Stenagostus rhombeus (CR), Dromaeolus barnabita, and Osmoderma eremita s. l. – a species protected by the EU Habitats Directive. The results indicate the importance of the Wolin National Park as a key refuge for saproxylic beetle diversity in northwestern Poland. https://www.forestry.actapol.net/volume24/issue1/5_1_2025.pdf Wolin National Park saproxylic beetles biodiversity dead wood protected species
