Opis:
The current knowledge on the occurrence of Lobaria amplissima, a very rare old-growth forest lichen in Poland, is discussed. Both previous and new localities are presented. The Białowieża Forest, from which L. amplissima is reported, is a refuge site of L. amplissima in the lowland forests of Central Europe. The most important data on the ecology and the general distribution of the species are given. Diagnostic characters related to the morphology, anatomy and chemistry of L. amplissima differentiating it from similar species are described.
Lobaria amplissima jest porostem znanym głównie z Europy, ale posiada również stanowiska w Makaronezji, Azji, Nowej Zelandii, a także w Ameryce Płn. i północnej części Afryki. Typ jej rozmieszczenia w Europie można określić jako oceaniczno-suboceaniczny, od Norwegii po Portugalię. Dalej w kierunku wschodnim występuje głównie w górach, np. w regionie śródziemnomorskim i w Europie Centralnej. Lobaria amplissima rośnie na pniach lub grubych konarach starych drzew liściastych, bezpośrednio na korze lub na epifitycznych mszakach. Rzadziej notowana jest na omszonych kwaśnych skałach. Porost ten jest bardzo wrażliwy na zanieczyszczenia powietrza i przekształcenia zbiorowisk leśnych, spowodowane zabiegami gospodarczymi. Jest on składnikiem ugrupowań epifitycznych ze związku Lobarion i jego występowanie ograniczone jest do najlepiej zachowanych ekosystemów leśnych. Pierwsze stanowisko L. amplissima w Polsce podali Kukwa i in. (2008) w wyniku rewizji okazu zdeponowanego w BSG, zebranego w Puszczy Białowieskiej i znanego wcześniej jako L. virens (Cieśliński i Tobolewski 1988; Cieśliński 2003, 2010). Kolejne stanowiska L. amplissima zostały ostatnio znalezione przez A. Bohdana, w wilgotnych lasach olszowych w obrębie kilku części rezerwatu „Lasy Naturalne Puszczy Białowieskiej” i Białowieskiego Parku Narodowego. Wszystkie notowania pochodzą z kory przewróconych starych jesionów. Plechy zlokalizowane były w podkoronowej części pni i w koronie. W Polsce L. amplissima zarejestrowana została łącznie na 9 stanowiskach w Puszczy Białowieskiej, która jest prawdopodobnie ostatnim refugium tego gatunku na Niżu Środkowo-Europejskim. Omawiany gatunek, podobnie jak inni przedstawiciele rodzaju Lobaria, jest porostem ściśle chronionym w Polsce. W niedalekiej przyszłości powinien być objęty ochroną strefową, która dodatkowo zabezpieczy potencjalne nowe stanowiska, zwłaszcza jeżeli zostaną znalezione w lasach gospodarczych. L. amplissima powinna być także wprowadzona w miejsce L. virens na krajową czerwoną listę gatunków zagrożonych oraz do zestawienia indykatorów lasów puszczańskich. W pracy przedstawiono jedno dotychczas znane oraz nowe stanowiska L. amplissima, stwierdzone w latach 2010 i 2011. Uzyskane wyniki oraz przegląd danych dotyczących ekologii tego gatunku wskazują, że możliwe jest znalezienie w Polsce nielicznych nowych stanowisk tego rzadkiego porostu, ale tylko w najmniej zniekształconych lasach liściastych, o charakterze puszczańskim. Potencjalne miejsca występowania wydają się być ograniczone do dużych kompleksów leśnych w północno-wschodniej Polsce i w Bieszczadach. Najbardziej prawdopodobnymi forofitami mogą być jesiony w łęgach i olsach, jesiony i dęby w wilgotnych postaciach grądów, buki i jawory w zbiorowiskach leśnych w górach. Przeszukiwane powinny być górne części pni i grube, dolne konary przewróconych drzew. Obserwacje drzew stojących, za pomocą lornetki ornitologicznej, umożliwiają zauważenie tylko dużych (do 20-30 cm średnicy) plech, występujących dość rzadko (Ryc.2). Ze względu na podobieństwo, głównie do Lobaria virens i Flavoparmelia caperata, konieczne są badania laboratoryjne, w tym TLC. Najbardziej istotne cechy diagnostyczne omawianego gatunku to jasnoszara (w stanie suchym) górna powierzchnia plechy (wilgotna – szaro-zielona), z wyraźnymi marszczeniami w części środkowej i drobne, do 2 cm szerokości, karbowano-wcinane, częściowo podwinięte łatki. W materiałach z Polski nie stwierdzono bardzo charakterystycznych, brązowo-czarnych krzaczkowatych cefalodiów, występujących na górnej stronie plechy. Plechy zawierają skrobikulinę, rzadziej pseudocyfellarynę i atranorynę. Górna kora barwi się od KOH intensywnie jasno żółto, charakterystyczne są również reakcje miąższu: K+ ciemno żółty, PD–, C–, KC+ ciemno różowy lub czerwono-różowy.

Augustow Forest

Opis:
During the survey of the Mały Borek nature reserve (Augustów Forest, NE Poland) 236 species of vascular plants were recorded, including 10 plant species red-listed in Poland and 19 species protected under the Polish law. The most valuable species were sedges typical of the boreal coniferous forests: Carex vaginata, C. globularis and C. loliacea. The presence of neophytes was very limited (1,3% of the flora) in the area studied. The principal aim of the establishment of the reserve was the conservation of old-growth coniferous forests with long ecological continuity. Since the reserve studied consists mainly of old-growth coniferous forests, the number of species regarded as ancient forest indicators is lower (54 species) than in the well-preserved reserves with deciduous stands in north-east Poland, but still rather high. The most valuable, threatened species are bound to wetland forests that are presently disturbed due to drainage. Restoration of the former hydrological conditions is essential for the preservation of the vascular plants in the reserve.

Opis:
During the period from 2003 to 2011 observations of carabid community regression and selected habitat indicators were conducted on 15 plots in stands that had been disturbed by a hurricane and on 15 plots in control stands. Regression of carabid communities delayed 3−4 years was observed, consisting in increases in the number of species and the proportion of xerophilous species and reductions in the percentage of forest fauna and in mean individual biomass. Only after 7 years did these indicators begin to show a tendency in the reverse direction, albeit not very strong, indicating that carabid communities had begun to regenerate.

Opis:
The flowering and graft mortality of Norway spruce clones of Istebna origin was only slightly different from clones of other origin in the same seed orchard. The negative effect ofmoving Istebna clones from the south to the north of their origin was probably compensated by moving them from a higher altitude to lowland. There is a danger that the complete loss of several clones, observed in the seed orchard with time,may really decrease the expected level of genetic variation in the progeny. It is recommended that the mortality of grafts and the reduction in the number of clones in the seed orchard should be under permanent observation.

Opis:
Height-diameter models define the general relationship between the tree height and diameter at each growth stage of the forest stand. This paper presents generalized height-diameter models for mixed-species forest stands consisting of Norway spruce (Picea abies Karst.), Silver fir (Abies alba L.), and European beech (Fagus sylvatica L.) from Slovakia. The models were derived using two growth functions from the exponential family: the two-parameter Michailoff and three-parameter Korf functions. Generalized height-diameter functions must normally be constrained to pass through the mean stand diameter and height, and then the final growth model has only one or two parameters to be estimated. These “free” parameters are then expressed over the quadratic mean diameter, height and stand age and the final mathematical form of the model is obtained. The study material included 50 long-term experimental plots located in the Western Carpathians. The plots were established 40–50 years ago and have been repeatedly measured at 5 to 10-year intervals. The dataset includes 7,950 height measurements of spruce, 21,661 of fir and 5,794 of beech. As many as 9 regression models were derived for each species. Although the “goodness of fit” of all models showed that they were generally well suited for the data, the best results were obtained for silver fir. The coefficient of determination ranged from 0.946 to 0.948, RMSE (m) was in the interval 1.94–1.97 and the bias (m) was –0.031 to 0.063. Although slightly imprecise parameter estimation was established for spruce, the estimations of the regression parameters obtained for beech were quite less precise. The coefficient of determination for beech was 0.854–0.860, RMSE (m) 2.67–2.72, and the bias (m) ranged from –0.144 to –0.056. The majority of models using Korf’s formula produced slightly better estimations than Michailoff’s, and it proved immaterial which estimated parameter was fixed and which parameters were free.

Opis:
Black alder, an N-fixing tree is considered to accelerate the availability of phosphorus in soils due to the increased production of phosphatase enzymes, which are responsible for the P release from the litter. Acid phosphatase activity plays a pivotal role in organic P mineralization in forest soils and in making P available to plants. In order to check whether Alnus glutinosa stimulates acid phosphomonoesterase (PHACID) activity, we compared enzyme activities, total P concentration (PTOT), plant-available P (PAVAIL), organic P (PORG) and inorganic P (PINORG), and organic matter content in 27 ancient and 27 post-agricultural alder woods (the latter ones representing different age classes: 11-20, 21-40 and 41-60 years) of soil samples taken from the litter and the mineral layers. Phosphomonoesterase activity, organic matter, PTOT, PINORG and PORG concentrations were significantly higher in ancient alder woods than in the soils of post-agricultural forests. Significant differences in the acid phosphatase activity, organic matter and PAVAIL concentration were noted between the litter and mineral layers within the same forest type. In recent stands the amount of organic matter and phosphatase activity increased significantly with the age of alder stands, although only in the mineral layer of their soils. Phosphomonoesterase activity, organic matter and PAVAIL content were higher in a litter layer and decreased significantly at a mineral depth of the soil. The acid phosphatase activity was significantly correlated with organic matter content in both ancient and recent stands. There was no significant relationship between PHACID activity and any P forms.

Opis:
We studied the relationship between tree-species diversity and the above-ground biomass on an example of two natural Polish forest with different altitiudinal range, plant species pool, vegetation and climatic conditions. The study sought to determine whether: (1) above-ground biomass in natural forests correlates with tree-species diversity irrespective of the kind of forest (montane or lowland), and (2) the relationship in question is negative, (3) the above-ground biomass is greater in montane forests than in lowland ones. Natural forests present in 1º Polish Gorce Mountains (montane forest) alongside comparable data for the 2º world-renowned lowland forest that is present in the Białowieża National Park. Data were collected within 558 sample plots (á 200-square-metre). The diameter at breast height of all trees with girths of or exceeding 12 cm was measured. To compute above-ground biomass we calculated dry masses for each tree on the basis of values for dbh and height, next we summed these values for all species present within each plot. The number of tree species on a plot ranged from only one (mainly in spruce stands) to six (in mixed deciduous lowland forest stands). The above-ground accumulated biomass ranged from 6 to 1155 (average 251±13) t ha–1 within the lowland forest, and from 2 to 849 (average 242±8) t ha–1 within the montane forest. We concluded that there was a humped-back shaped relationship between tree-species diversity and above-ground biomass in both lowland and montane natural forests.

Opis:
The effects of drought stress, stress by increased nitrogen depositions and the combined effect of the two stress factors on the growth of Norway spruce Picea abies (L.) Karst. were studied in two stands. The drought stress was induced by reducing atmospheric precipitations by 60% and the increased nitrogen depositions were simulated by repeated applications of ammonium sulphate at a rate corresponding to 100 kg N ha–1 year–1. All stress factors under study affected the height increment of the above-ground part, the length and colour of needles, and the biomass, vertical distribution, functionality and mycorrhizal infection of fine roots. The root system responded to the simulated stresses right from the the very first year of their action, exhibiting a greater damage than the above-ground part of the plant. Drought acted as a stress factor stronger than the nitrogen depositions themselves. The strongest impact was recorded in the simultaneous influence of the stress factors.

Opis:
The study aimed to investigate effectiveness of forest management zoning in conserving biodiversity of Mabira forest reserve. The study sites buffer, production, and strict nature reserve management zones were purposively selected. This was undertaken through investigating woody species diversity, composition and structure. A total of 60 sampling plots with a size of 20 m x10 m were used to collect vegetation data. Variables such as woody plant species identification and counts as well as diameter at breast height (DBH) of trees were done. The result depicted a total of 65 woody species; 39 in buffer, 19 in productions and 37 in strict nature reserve. Of these, only 9 trees species were found common to all zones and their Sorensen similarity coefficient was 0.2213. The population structure of the buffer and strict nature reserve zones was found to be a J - shape pattern, whereas the production zone shown an inverted J-shape pattern. Higher woody species diversity was depicted in the buffer and strict nature zones with (H’=2. 73512) and (H’=2. 68412) respectively, and lower in a production zone (H’=1. 63628). The evenness index value of a buffer zone was (J =0. 746574), strict nature (J= 0.743335) and production (J=0. 555719). The production zone had shown higher IVI values followed by buffer and strict nature reserve zone. The most important woody species identified based on their IVI value were Broussonetia papyrifera (Production), Acalypha neptunica (Buffer), Funtumia Elastica (strict nature reserve). The existing forest management is effective in conserving the biodiversity of the forest reserve. Nevertheless, the production zone was still suffering from exploitation of the surrounding community, hence serve for protecting the remaining management zones from further human interference. Further investigation is also required on the adjacent community perceptions of the forest management zoning.

Opis:
Attempts to study biodiversity hotspots on a regional scale should combine compositional and functionalist criteria. The detection of hotspots in this study uses one ecologically similar group of high conservation value species as hotspot indicators, as well as focal habitat indicators, to detect the distribution of suitable environmental conditions. The method is assessed with reference to thermophilous forests in Poland – key habitats for many rare and relict species. Twenty-six high conservation priority species were used as hotspot indicators, and ten plant taxa characteristic of the Quercetalia pubescenti-petraeae phytosociological order were used as focal habitat indicators. Species distribution data was based on a 10 × 10 km grid. The number of species per grid square was interpolated by the ordinary kriging geostatistical method. Our analysis largely determined the distribution of areas with concentration of thermophilous forest flora, but also regional disjunctions and geographical barriers. Indicator species richness can be interpreted as a reflection of the actual state of habitat conditions. It can also be used to determine the location of potential species refugia and possible past and future migration routes.

This paper presents the results of the ornithological research performed in the oldest dry coniferous forests of Kampinos National Park (central Poland). The field study took place on three 25-ha-sites overgrown with Scots pine Pinus sylvestris over 150 years old. The species composition of the dominant group was found to differ from that of other forests. Hole-nesters constituted the most important part of the population of birds together with old and mature forest specialists and residents. Hole-nesters were numerously represented (50% of all noted pairs). Old and mature forest specialists constituted 40% of all pairs. Seven species connected to natural forest clearings were also found to be of significant importance. The presence of such ecological groups is proof of the biological balance and diversity of the researched forests.

Opis:
This paper presents the results of a study of bird populations connected with the oldest forest stands of pine coniferous forests in Kampinoska Forest, where the pine trees are minimum 160 years old. It presents the basic results concerning the distribution, selectiveness and habitat preferences of hole-nesters and the birds connected with old forests in connection with habitat characteristics. The studied areas were dominated by hole-nesters, and a significant share was of birds connected with gaps left after broken trees. A large group was made up by birds which collect invertebrates among trees and then the species which feed on trunks and branches. Large dimensions of pine trees and numerous cracks in bark, cracks in trunks and hollows under windfallen tress served as microhabitats for particular bird species. The index of species diversity and number of pairs were similar in every area, probably due to dozens of years of forest protection, thanks to which similar quantity and quality parameters developed in the areas.
