Biodiversity As An Ecological Safety Condition. The European Dimension

The main purpose of the paper is to indicate the theoretical bases of biodiversity protection from the perspective of the natural and economic sciences, and to describe the diversity of biodiversity protection levels in the EU states. A specific aim is to indicate the forms and instruments of nature conservation involved in biodiversity protection, and to carry out an overview of established nature conservation programmes in selected EU countries. In order to accomplish such a complex aim, this article presents an overview of literature found in the natural, economic and legal sciences and popular magazines presenting scientific research within the field of biodiversity. Then a comparative analysis is presented based on the statistical data coming from various international statistics resources (OECD, EUROSTAT, EEA)

Congruence between breeding and wintering biodiversity hotspots: A case study in farmlands of Western Poland

Farmland landscapes are recognized as important ecosystems, not only for their rich biodiversity but equally so for the human beings who live and work in these places. However, biodiversity varies among sites (spatial change) and among seasons (temporal change). In this work, we tested the hypothesis that bird diversity hotspots distribution for breeding is congruent with bird diversity hotspots for wintering season, focusing also the representation of protected areas for the conservation of local hotspots. We proposed a framework based on the  use of species richness, functional diversity, and evolutionary distinctiveness to characterize avian communities. Although our findings show that the spatial distribution of local bird hotspots differed slightly between seasons, the protected areas’ representation was similar in both seasons. Protected areas covered 65% of the most important zones for breeding and 71% for the wintering season in the farmland studied. Functional diversity showed similar patterns as did bird species richness, but this measure can be most effective for highlighting differences on bird community composition. Evolutionary distinctiveness was less congruent with species richness and functional diversity, among seasons. Our findings suggest that inter-seasonal spatial congruence of local hotspots can be considered as suitable areas upon which to concentrate greater conservation efforts. However, even considering the relative congruence of avian diversity metrics at a local spatial scale, simultaneous analysis of protected areas while inter-seasonally considering hotspots, can provide a more complete representation of ecosystems for assessing the conservation status and designating priority areas

The chosen socio-economic problems of protecting valuable agricultural land in Natura 2000 areas in Poland

Purpose: Intensive development of agriculture has led to the loss of many valuable ecosystems and thus to a significant impoverishment of biodiversity in rural areas. In the context of the analysed research problem, i.e. the functioning of agriculture in N2000 areas, Poland is a special country where there are semi-natural unique habitats disappearing in the European landscape. The aim of the study was to assess the effectiveness of conservation measures financed under the EU CAP on agricultural land located on N2000 areas. Design/Methodology/Approach: The analytical material consisted of the results of surveys using a standardized questionnaire which carried out among 292 farmers (152 organic farmers and 140 conventional farmers) from the the area of N2000 "Biebrza Valley" PLH200008. The assumptions were verified based on the Kruskal-Wallis ANOVA analysis and gamma rank correlation. The analytical material also consisted of EUROSTAT data on the area of the N2000 network and the area of agricultural land covered by this form of protection in EU countries. These data were subject to horizontal and vertical (years 2009-2017) comparative analysis. Findings: Polish experience regarding the implementation of conservation measures on naturally valuable agricultural land (N2000) allows to state that environmental policy should be based on the idea of socially sustainable agriculture, including ecological sustainability (proper delimitation of areas predestined for protection, their environmental valorisation, development of conservation measures and their implementation, a bonus system for the sustainability of agri-environmental commitments), economic sustainability (the system of agricultural subsidies and/or other solutions to meet the basic living needs of farmers and their families), social sustainability (effective inclusion of local communities in information, education and decision-making processes at the stages of development, deployment and implementation of protection programs). Practical Implications: The recommendations resulting from the conducted research and analyses may be adopted by the institutions responsible for the creation of an environmental protection policy which can improve the effectiveness of active forms of protection in valuable natural habitats that are used for agriculture. Originality/Value: The article indicates the recommendations based on building a lasting relationship between farmers and the protection of the environment.peer-reviewe

Seasonal changes in avian communities living in an extensively used farmland of Western Poland

To study the seasonal changes in avian communities, we collected data in an extensively used farmland in Western Poland during 2006-2013. Generalized additive mixed models were used in order to study the effects of seasonality and protected areas on the overall bird species richness. A similarity percentage analysis was also conducted in order to identify the species that contribute most strongly to dissimilarity among each bird according to the phenological season. Furthermore, the differences in bird communities were investigated applying the decomposition of the species richness in season, trend, and remainder components. Each season showed significant differences in bird species richness (seasonality effect). The effect of the protected areas was slightly positive on the overall species richness for all seasons. However, an overall negative trend was detected for the entire period of eight years. The bird community composition was different among seasons, showing differences in terms of dominant species. Greater differences were found between breeding and wintering seasons, in particular, the spatial pattern of sites with higher bird richness (hotspots) were different between breeding and wintering seasons. Our findings showed a negative trend in bird species richness verified in the Polish farmlands from 2006. This result mirrors the same negative trend already highlighted for Western Europe. The role of protected areas, even if slightly positive, was not enough to mitigate this decline process. Therefore, to effectively protect farmland birds, it is necessary to also consider inter-seasons variation, and for this, we suggest the use of medium-term temporal studies on bird communities’ trends

Umbrella species as a conservation planning tool

In northern Europe, a long history of anthropogenic land use has led to profound changes within forest ecosystems. One of the proposed approaches for conservation and restoration of forest biodiversity is the use of umbrella species, whose conservation would confer protection to large numbers of naturally co-occurring species. This thesis aims to evaluate some of the prerequisites to the umbrella species concept, focusing on resident birds in hemiboreal and boreal forests. The study was performed in four areas belonging to the southern Baltic Sea region: central and southern Sweden, south-central Lithuania and northeastern Poland. A review of empirical evaluations of the umbrella species concept performed in various systems suggested that multispecies approaches addressing the requirements of both the umbrellas and the beneficiary species have better potential than approaches based coarsely on the area needs of single species. An analysis of co-occurrence patterns among resident forest birds in landscape units of 100 ha showed that some species reliably indicated high species richness through their presence. For birds of deciduous forests, there was high cross-regional consistency in the identity of the best indicators. Specialised woodpeckers (Picidae) were prominent among the species that performed well as indicators. Their presence in the landscape units was generally linked positively to the degree of naturalness of the forest and to the amounts of resources that have become scarce in intensively managed forests, such as dead wood and large trees. In Sweden, occurrence of the white-backed woodpecker (Dendrocopos leucotos) in bird atlas squares was positively related to species richness among forest birds of conservation concern, as well as to the area of deciduous and mixed forests of high value for conservation. Moreover, the number of red-listed cryptogam species linked to deciduous trees and dead wood was higher where the woodpecker bred. Those results for birds of northern forests suggest that the umbrella species concept may constitute a useful component of conservation planning, especially in the work towards the derivation of quantitative targets. However, umbrella species are not a panacea and should therefore be seen as part of a complementary suite of approaches

An economist looks at ecosystem services

This chapter lists ecosystem services and discusses what techniques can be applied in order to assess their economic value. The last five decades witnessed enormous progress in developing valuation techniques applied to non-market goods (i.e. the goods that do not have market prices). These can be broadly divided into direct and indirect techniques. The former aim at capturing them directly e.g. by asking people “how much they are willing to pay”. The latter derive values from observing prices not for the good of interest, but rather for a complementary good whose characteristics shed some light on peopleʼs relevant preferences. These techniques were successfully tested in many regions of the world, including Poland. The best known exercise of this sort is the one published by Nature in 1997, where an attempt was made to estimate the global economic value of annual ecosystem services. Numerous subsequent studies have allowed for much more accurate assessments. Consequently, researchers addressing valuation problems have an extensive accumulated research experience to rely on.Wydanie współfinansowane ze środków Miasta Łodzi w ramach zadania “Współpraca z wyższymi uczelniami” – umowa 100/03/201

Changing Land Use in Recent Decades and its Impact on Plant Cover in Agricultural and Forest Landscapes in Poland

The objective of this paper is to present the effects of general changes in land use in recent decades on plant cover structure in Poland. The paper is focused on spontaneous processes that occur in agricultural and forest areas being no longer under human pressure. Studies carried out in different geobotanical regions of Poland demonstrated that the directions and range of dynamic changes in plant cover are similar across the country. The formation of secondary forest phytocenoses, on the lands delivered from human activity is a common ecological process observed today in the agricultural landscape. In the dynamics of forest vegetation the basic process is regeneration after ceased use, and the introduction of legal protection
