Opis:: In some parts of the country, the moose density is so high that it is causing serious damage to forestry and agriculture. In addition, collisions between motor vehicles and moose crossing roads or railroad tracks are becoming more frequent. The number of moose in Poland is expected to increase. So far, there have been considerations to allow hunting of these animals again, which would theoretically reduce economic losses, support forest management and increase the safety of travelers. However, recent research on moose populations suggests that ongoing climate change is affecting their habitats and physiological condition to such an extent that there could soon be a slowdown in population growth and a risk of collapse. The increasing population of large predators in forest ecosystems may also lead to increased mortality, so the current growth rate of the moose population could be directly disrupted in the near future. Other ecological aspects of the moose population may facilitate the management of this species. There are increasingly advanced and effective methods based on population trends or biological indicators that can be used to monitor the status of the population more easily and effectively. In order to ensure sustainable management of the native moose population in Poland, it is crucial to update knowledge about the ecological aspects affecting the population and its dynamics, which have been ignored or not sufficiently taken into account so far.

Opis:: Estimation of the CO2 storage potential of gas-bearing shales in the Lower Paleozoic Baltic Basin is at an early stage of reservoir exploration and production, based on data from one vertical exploration borehole, supplemented with some information from adjacent boreholes. The borehole section examined is 120 m long and comprises three intervals enriched with organic matter separated by organic-poor intervals. In our approach, the storage capacity is represented by: (1) sorption potential of organic matter, (2) open pore space and (3) potential fracture space. The potential for adsorbed CO2 was determined from Langmuir isotherm parameters taken from laboratory measurements and recalculated from CH4 adsorption curves. The pore space capacity was estimated in two ways: by utilizing results of laboratory measurements of dynamic capacity for pores >100 nm and using results of helium porosimetry, the first of these being considered as the most relevant. Due to the low permeability of the shale matrix we have adopted the standard assumption that the CO2 is able to reach effectively only 10% of the theoretical total sorption and pore volume. For hydraulic fracture space, the theoretical maximum opening of vertical fractures in the direction of minimum horizontal stress was considered, decreased by the expected portion of fracturing fluid flowback and by partial fracture closure by burial compaction. The effectiveness of three CO2 storage categories for the individual organic-rich and organic-poor shale units shows an obvious positive correlation of TOC content with the storage efficiency by sorption and within pore space, and a negative correlation with the storage efficiency in hydraulic fractures. It was estimated that sorption, over the maximum storage interval (120 m thick), is responsible for ~76% of total storage capacity, pore space accounts for 13% (for the most relevant porosity model) while the contribution of fractures is about 11%. In the minimum storage interval (35 m thick, including the best quality shales) the estimated proportions of sorption, pore space and fractures in the total storage capacity are 84, 10 and 6% respectively. Finally, the result for the best quality storage interval (35 m thick) was compared with the Marcellus Shale of similar thickness (average ~38 m) and with other options of CO2 storage in Poland. The most organic-rich units in the area studied have a CO2 storage capacity efficiency (i.e. storage capacity per volume unit of shale) only slightly less than average for the Marcellus Shale, because sorption capacity – the dominant component – is comparable in both cases. However, the open pore space capacity in the Marcellus Shale appears to be far higher, even if the potential fracture space calculated for the borehole studied is taken into consideration, probably because the free gas content in the Marcellus Shale is far higher than in the Baltic Basin. CO2 storage in depleted shale gas wells is not a competitive solution compared to storage in saline aquifer structures or in larger hydrocarbon fields.

Opis:: On June 30, 2021 the Polish Minister of Climate and Environment announced the boundaries of five areas dedicated for the next, 6th tender round for hydrocarbon concessions in Poland, planned for the second half of 2022. These are: Block 413-414, Block 208, Cybinka-Torzym, Zielona Góra West, and Koto tender areas. The main exploration target of these areas is related to conventional and unconventional accumulations of gas and oil in the Carpathian basement, Carpathian Foredeep and Outer Carpathians (Block 413-414), as well as in the Carboniferous, Permian Rotliegend, Zechstein Limestone, and Main Dolomite (Block 208, Cybinka-Torzym, Zielona Góra West) and in the Mesozoic of the Polish Lowlands (Koto). The other way of granting hydrocarbon concessions in Poland is the open door procedure, in which an entity may apply for concessions for any other area.
