geometric and natural convention of determining indicators of forest diversity
uneven−aged forest
diversity characteristics
Opis:
There are two conventions of determining indicators of forest diversity: geometric and natural. Indicators in the geometric convention are determined from the ratio of differences in the values of the real characteristic to the value of the characteristic adopted as a comparative norm. Indicators in the natural convention are determined from the ratio of differences in the values of a characteristic in the real world to the mean value of that characteristic by standard deviation. The indicator−based assessment of forests in Poland is based on the geometric convention of similarities and standards included in yield and stand volume increment tables. This convention of similarities (map and plan scales) taken directly from technology has no natural justification. Therefore, it is necessary to determine indicators of forest diversity based on natural convention with special reference to the uneven−aged forests based on natural forests.

Opis:
Structural diversity is one of the most interesting phenomena that have been studied by forest ecologists and practitioners. Amongst the different characteristics of forest structure, spatial diversity of trees and their attributes seem to be very important. The more spatially structured a population is, the higher its diversity in terms of size and species richness. Because most forests in Europe are managed and were artificially established, they are subjected to conversion processes turning them into more complex systems. The approach presented here aims at elucidating whether natural processes, such as self-thinning, can cause the self-differentiation of spatial structure in artificially planted stands. Our analyses focused on untended Scots pine and pedunculate oak stands in the juvenile phase of development and were based on spatially explicit structural indices for positioning and size differentiation (diameter, total height and crown length). The obtained results indicate that live trees were dispersed more or less regularly. Unlike the anglebased index, which mostly indicated randomness in tree location, a distance-based index showed clear regularity. We also found that the distribution of tree attributes auto-correlates to tree location as indicated by significantly lower index values compared to values resulting from random reassignment of the examined attributes. This low degree of spatial differentiation is further confirmed by the distribution of indices in differentiation classes. Our results allow us to conclude that, in the case of light demanding species (pine and oak), natural processes do not increase spatial diversity of the stand, although, both species showed a certain degree of deviation in this respect.

The paper presents socio-ecological and ecological characterisation of 72 bryophyte species found in the years 2008-2012 on midforest roads passing through nine nature reserves situated in the Łódź region. Nine species occurred excl usively in this habitat. Most of the species noted (63%) were forest bryophytes occurring also inside the forest phytocoenoses studied, they constituted 95.5% of all the records. The non-forest species show diff erent socio-ecological relations: some of them occur typically on meadows or in grassy forest ecotones, others – in fens or bogs but there are also some pioneer bryophytes colonizing initial sites, both of natural and anthropogenic character. They diff er from the forest species occurring on midforest roads in their ecological demands regarding the habitat reaction (presence of subneutral species) and light (higher participation of heliophytes). Nine of them (13%) are considered to be synanthropic bryophytes. Details of the species occurrence are provided.

The process of forest fragmentation has been observed in many countries, where plant species had adapt to different habitats, such as for example manor parks and rural plantings. A number of scientists have studied the parks as sites where waning environments and landscapes find their shelter. In 2011–2012, research was undertaken on diversity of vegetation in afforestations of parks, rural plantings and oak-hornbeam forests in Sandomierz Basin. In order to compare the means obtained univariate analysis of variance (one-way ANOVA) was used with juxtaposing divided by each of the two criteria: size (the small, and large parks) and conservation(cultivated parks and nonclutivated parks). Tukey’s test was used to examine the significance of differences between respective groups. Analyses were with STATISTICA 9.1. software. Plants classified as forest species, grassland species and those of synanthropic communities were observed in all the afforestations. The parks with high wooded and not mowed areas and oak-hornbeam forests were more forest-like than other types of afforestations studied.

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.

Ectomycorrhizal communities structure of Norway spruce (Picea abies L. (Karst.) was studied in four mature forest stands: Brenna, Salmopol, Zwierzyniec and Mirachowo. Morphological classification was used to distinguish the major mycorrhizal types associated with spruce in different forest types. Three of the foreststands were located within the natural geographical range of Norway spruce (Brenna, Salmopol, Zwierzyniec) and one (Mirachowo) was located in so-called “spruce-less zone”. The sites differed in terms of environmental pollution. The mountain sites (Brenna, Salmopol) were characterized by relatively high levels of air pollution. The upland forest stand (Zwierzyniec), located in the southeastern part of Poland, was affected by a moderate pollution. The lowland stand in northern Poland (Mirachowo) was free from direct impact of anthropogenic pollution. The level of mycorrhizal colonization was 100% at all the study sites. Thirty-seven mycorrhizal morphotypes were distinguished in total. The number of ectomycorrhizal morphotypes varied between sites from 12 in Salmopol to 28 in Zwierzyniec. From one to three dominant morphotypes were found at the study site. Site-specific morhotypes were also observed. The frequency of mycorrhizal morphotypes differed between the forest stands.

This study uses quantitative forest surveys, interviews, discussions, and descriptions of the historical context of public participation in forest management including a detailed assessment of field conditions. The findings of a forest resources inventory show that (1) from the three sampled areas, Doi Laung Wildlife Sanctuary has highest richness, followed by village #16 and #14, and (2) Huaikhon #16 implied the process of framework to maintain a healthy condition and response to community needs with collective management. The conceptual model assessment that links key group indicators and drivers is presented based on previously developed assessment models. The framework focuses on the best way to provide forest management, forest fire prevention, and firefighting as well as monitoring of Check-dam construction and other activities that support the recovery of the forest community. This paper demonstrates the general of an environmental assessment framework to applying organize environmental information to facilitate policy decision making for the sustainable development.

Opis:
Fragmentation of landscapes and habitats has been identified as the main driver of biodiversity loss. Ecological corridors may support the conservation of biota in fragmented landscapes due to enhanced habitat connectivity. We conducted a study in order to assess the potential of a linear woodland landscape element along a railway line as ecological corridor using carabid beetles as indicators. The results showed that for some forest species the studied woodland strip has potential as an ecological corridor. Trophy and soil acidity were most often significantly correlated with parameters and species, but width of the woodland strip and distance from the forest site were of highest importance for the formation of the whole carabid assemblages. The results of our study provide with information regarding rules for the construction of woodland strips as ecological corridors. Management strategies should integrate such areas in concepts of sustainable regional development.

Opis:
The oak forests growing on the Krotoszyn Plateau are the biggest and most valuable oak forest complexes in Poland. The purpose of this study was to analyze the structural diversity of oak (Q. robur L.) stands older than 140 years. Two natural stands located within the forest reserve as well as two managed stands were chosen for investigation. Species and tree size diversity were analyzed using different measures and spatially explicit and inexplicit indices. The results indicate that the structural diversity of the protected oak forests did not differ significantly from that of managed stands. On the contrary, undisturbed natural processes in protected forests can result in a low diversity of some structural attributes in such stands. Although most indices pointed towards a higher structural diversity in protected forests, the differences were not large, especially in the case of spatially explicit indices. The spatial arrangement of live trees was either random, aggregated or regular, with the latter clearly dominating managed, poorly mixed oak stands. Furthermore, a lack of natural disturbances strong hornbeam expansion, in which case strict protection is not favorable for oak sustainability as it creates unsuitable conditions for oak regeneration beneath the hornbeam canopy.

Opis:
The present study has attempted to highlight the avifaunal diversity in two contrasting seasons (pre and post monsoons) from a protected tropical mixed deciduous forest (Kuldiha Wildlife Sanctuary, KWS) in the state of Odisha, India. Through modified line transect method, a total of 107 species of birds belonging to 49 families under 15 orders have been reported. Among them, 12 are winter visitors, 3 are summer visitors, 1 is near threatened and 1 is vulnerable species. Insectivores and frugivores constitute major foraging guilds. Closed canopy forests, forest edges, woodland areas and wetlands provide suitable habitats to all those avifauna. Lower canopy level was found to act as the major microhabitat for several species for meeting major ecobiological attributes of avifauna. The pre-monsoon and monsoon periods have appeared to be the ideal nesting seasons for most of the avian members. Canopy foliage and tree holes were seen to offer the most suitable nesting sites. Significant differences in respect of species richness have been observed among different habitats in different seasons (F5.91 ,p ≤ 0 in premonsoon, F6.53, p ≤ 0 in post monsoon). The highest Shannon Weiner diversity index (H′) was recorded from the forest edge (3.8) during premonsoon and that of lowest in orchard or plantation areas (2.96) during post monsoon. Species Dominance value (D) was observed to be highest both for grassland and orchards and plantation areas (0.06). The field based study attempts to assess avian diversity (qualitative and quantitative) in the light of global conservation programme. Though this area is prone to varying levels of anthropogenic interventions particularly the tourism activities, an overall healthy bird diversity has been found to exist, the knowledge on which is expected to be utilized for the holistic eco-management of forest ecosystem in general and Kuldiha wildlife sanctuary in particular. A number of hypothesis have been proposed in respect of avifaunal habitat selection, diversity and acclimation with wildlife friendly human association for their successful coexistence.

This paper presents the results of floristic studies conducted in the years 2003 – 2005 within the area of the Polesie National Park. The aim of the research was to compare the flora of initial succession stages in drainage ditches with the flora of neighbouring forest areas undergoing transformation as a result of drainage. Floristic lists were made in four designated study areas as well as in forest phytocoenoses. The results of field investigations were subjected to analysis with regard to the systematic affinity of the flora and proportions of plant life-forms as well as of historical-geographical groups and range groups. In the species composition of the studied drainage ditches hemicryptophytes were the dominant group of plant higher life-forms, whereas in the neighbouring communities the flora was represented by both hemicryptophytes and megaphanerophytes. In historical and geographical terms, the flora of drainage ditches and neighbouring communities represents definitely the group of spontaneophytes. Anthropogenic habitats, which developed within the drainage ditches, were colonised by native flora species characteristic for the Polesie National Park area.
Praca przedstawia wyniki badań florystycznych prowadzonych w latach 2003–2005 na terenie Poleskiego Parku Narodowego. Celem niniejszej pracy było porównanie flory inicjalnych stadiów sukcesyjnych w rowach melioracyjnych, z florą przekształcających się wskutek odwodnienia, sąsiadujących terenów leśnymi. Na czterech wyznaczonych powierzchniach badań, a także w fitocenozach leśnych sporządzono spisy florystyczne. Wyniki badań terenowych poddano analizie kameralnej pod kątem przynależności systematycznej flory, udziału form życiowych roślin, a także grup historyczno-geograficznych i grup zasięgowych. W składzie gatunkowym, badanych rowów melioracyjnych dominującą grupą form życiowych roślin wyższych są hemikryptofity, podczas gdy w zbiorowiskach sąsiadujących z nimi florę reprezentują zarówno hemikryptofity jak i megafanerofity. Pod względem historyczno-geograficznym flora rowów melioracyjnych, jak i zbiorowisk sąsiadujących, reprezentuje zdecydowanie grupę spontaneofitów. Antropogeniczne siedliska, jakie wykształciły się w obrębie rowów melioracyjnych zasiedlone zostały przez gatunki flory rodzimej charakterystyczne dla terenu Poleskiego Parku Narodowego.

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.
