Opis:: The study investigates the intra-population variability of the growth and quality traits of Norway spruce populations from Bliżyn and Zwierzyniec Lubelski. The two populations are included in the IUFRO 1972 experiment and exhibit a high growth dynamics and a narrow crown form. The research was carried out on the experimental plot established in 1996 in Chrosno (Kutno Forest District) using 8228 two-year-old seedlings planted in a single-tree plot design at a spacing of 1.5 × 1.5 m. The seedlings represent 191 open-pollinated families, among them 93 families of Norway spruce from the Bliżyn region and 98 families from the Zwierzyniec Lubelski region. The height, height increment and DBH of trees were measured periodically, and some quality traits were assessed. The last results come from the measurements done on the trees aged 10 years. It was found that the differences between the two populations of Norway spruce are statistically nonsignificant but both of them show wide within-population variability. This suggests that they have the potential to flexibly respond to future changes in the growth conditions or to seed transfer to other seed zones. Survival in the environmental conditions of the experiment was independent of family.

Opis:: The natural stands of Norway spruce in Poland are split between the southern and the northeastern parts of the country. Two so-called "spruceless" zones separate the northern spruce locations from those in the south, one "spruceless" zone is situated in Central Poland, and the other one in the Beskid Mts. Mitochondrial (STS) and nuclear (SSR) markers were used to perform the genetic identification of Norway spruce. Four different variants of haplotypes, "a", "b", "c" and "d", were found to occur in the nad1 locus of STS markers. Populations from the northern range of Picea abies distribution in Poland harboured exclusively haplotypes "c" and "d", except for the Białowieża population which had haplotypes "a" and "c". Populations from the "spruceless" zones contained four types of haplotypes whilst those from southern Poland were mostly composed of haplotype "a". High mean gene diversity was observed for both STS and SSR markers (HT = 0.529, and HT = 0.851, respectively). The total genetic differentiation of Norway spruce populations was very low (FST= 0.088). Two main groups of populations were distinguished in the dendrogram defined by Nei's genetic distances based on microsatellite markers. The distribution of the genotypes was scattered and did not show any connection with the spatial distribution of P. abies in Poland. Only the mtDNA markers were able to differentiate the northern populations of Norway spruce from the southern ones, proving the historical separation between the Baltico-Nordic and the Hercyno-Carpathian ranges of P. abies in Poland. By contrast, the microsatellite data suggested an overlap between the genotypes due to the human manipulation of Norway spruce stands in the past.

Opis:: Carex secalina, a species recognized as extinct in Poland for 40 years, was re-discovered in 2000 and it’s natural populations covered by monitoring. From among nine historic localities, only for two - Jacewo and Turzany, in the vicinity of Inowrocław - the occurrence of the species was confirmed. In the course of the field studies, six new localities, not previously recorded in literature, were discovered. The sedge occupies sub-halophytic habitats in which it occurs along with halophytic species (particularly, such as Glaux maritima and Pucinellia distans) and a group of ruderal taxons. One of the newly discovered localities of C. secalina comprises an anthropogenic habitat. On the whole, the population sizes ranged from 20 to 350 individuals. The studies revealed a positive correlation between the size of a population and cattle pasturing, i.e. C. secalina forms the largest populations in the habitats remaining under the intense pressure of grazing and treading. Moreover, it was found that the high generative reproduction rate compensates the damage caused by animal grazing. The results suggest that an active protection of the sedge populations through the agricultural use of its habitats is the only effective way of securing it’s further occurrence in Poland, while including the sub-halophytic pastures with C. secalina in the agricultural and environmental program should be a priority task in the nearest future.

Opis:: Nadrzewna populacja sokoła wędrownego Falco peregrinus występowała w Europie od północno-wschodnich Niemiec aż po Ural. Wyginęła m.in. na skutek zatrucia środowiska. Ostatnie gniazda w Polsce stwierdzono w 1964 roku. W innych populacjach zdarzały się pojedyncze przypadki gniazdowania na drzewach, jednak nigdzie, poza Australią, nie powstała populacja nadrzewna. Sokolnicy zaczęli hodować sokoły wędrowne, opracowali metody intensywnej hodowli, a następnie reintrodukcji. Dzięki wycofaniu z użytku DDT w większości krajów sytuacja sokoła wędrownego zaczęła się poprawiać, populacje zaczęły się odbudowywać. Dzięki reintrodukcjom proces ten w wielu miejscach został znacznie przyśpieszony, powstały też populacje odbudowane od zera. Niestety populacja nadrzewna nie zaczęła się odradzać w sposób naturalny. W Polsce w latach 1990-2009 wypuszczono łącznie 345 sokołów, z czego 291 na terenach leśnych. Łącznie do 2009 roku stwierdzono 15 stanowisk lęgowych, z których łącznie wyleciało 110 młodych sokołów. Znane stanowiska znajdują się na terenach miejskich oraz w górach. Planowane są dalsze prace na rzecz przywrócenia populacji nadrzewnej w Polsce, a także na Białorusi i Litwie.
Tree-nesting population of the Peregrine Falcon Falco peregrinus occurred in Europe from the north-eastern Germany up to the Urals. It went extinct as a result of environmental contamination. The last nests in Poland were found in 1964. In other populations there were isolated cases of nesting in the trees, but nowhere, apart from Australia, the population was not tree-nesting. Falconers began to breed Peregrine Falcons, have developed methods for intensive breeding and reintroduction. With the ban on DDT in most countries, the situation of the Peregrine Falcon began to improve, populations that survived the crisis began to rebuild. Thanks to reintroduction, this process in many places has been significantly accelerated, it helped to emerge populations rebuilt from scratch. Unfortunately, the tree-nesting population did not begin to regenerate naturally, so the only hope is the reintroduction. In Poland in 1990-2009 total of 345 falcons of the subspecies Falco peregrinus peregrinus were released, of which 291 in forests. Up to 2009 there were found 15 breeding posts, which resulted in a total of 110 young falcons. Known positions are in urban areas and in the mountains. Further work is planned to restore tree-nesting populations in Poland, Belarus and Lithuania.
