Alarming disappearance of a number of plant and animal species or even entire natural habitats of high conservation value has become a clear impulse to preventing measures and consequently, the initiatives to stop the unfavorable processes. Lenient grazing of farm animals is considered an effective tool for widely understood conservation of nature. However, the negative effect of too intensive grazing practices should be also borne in mind when disturbed ecological stability of land may occur as a result of the erosion process, caused by over-grazing and stock treading damage. Importantly, the appropriate animal species' match encourages appropriate grazing on land of conservation value. A detailed analysis of vegetation changes on the grazing land indicates that the use of farm animals of native breeds to limit the secondary plant succession on completely abandoned land contributes to protection of floristic biodiversity and maintains landscape richness. Besides, it improves the conservation of farm animal genetic resources as well as valuable habitats. It was noted that animals exhibit a very selective grazing behavior, e.g. sheep did not select the species typical of xerothermal psammophilic grasses such as Corynephorus canescens and Cladina mitis. Actually, sheep damaged these species with hooves while roaming the land searching for feed. In consequence of the active protection implementation (conservation grazing), the secondary succession of trees and shrubs was limited as these plant species were nibbled or damaged by grazing animals. The highest decrease was reported in the second and third research year in the plant group up to 30 cm high and within a range 30-80 cm. During the free-range grazing practices aiming at conserving valuable natural habitats, the animal welfare was ensured and permanent control of available nutritional resources performed. In many cases, the introduction of conservation grazing for active protection of natural habitats has conferred the first benefits, i.e. an increase of the numbers of bird breeding species. The research results of the studies mentioned in the present paper fully support the use of farm animals for active protection of nature and at the same time, highlight the necessity of economic tools’ introducing to promote the proposed solutions.

According to the Council Directive 92/43/EEC on the conservation of natural habitats and of wild fauna and flora (Habitats Directive), the Member States of the European Community are obliged to undertake the surveillance of the conservation status of the natural habitat types and species covered by the Annexes I, II, IV and V of this Directive and report on the results of this surveillance each 6 years. To meet these requirements the project entitled Monitoring of species and natural habitats, with particular reference to the special areas of conservation of the Natura 2000 network – phase I and II was carried out in Poland in the years 2006–2008. The project was supervised by the Chief Inspectorate of Environmental Protection, financed by the National Fund of Environmental Protection, and coordinated by the Institute of Nature Conservation PAS in Kraków. The main goals of the project were to develop and implement monitoring schemes for selected habitat types and species, especially those defined as “priority” ones, and assess their conservation status on the basis of monitoring results. Studies were carried out in localities situated mostly in the proposed sites of Community importance of the Natura 2000 network but also outside the network. The scope of data collected at a locality level was based on guidelines for reporting under Article 17 of the Habitats Directive. Conservation status of a habitat type at a monitoring locality was determined on the basis of three parameters: habitat area, structure and functions and future prospects, while conservation status of species, on such parameters as population, habitat of species and future prospects. Selected indices were used do assess the current status of “habitat structure and functions”, “population of species” and “habitat of species”. Future prospects were judged by experts on the basis of e.g. identified main pressures and threats, current conservation status, already applied conservation measures etc. Indices and parameters of conservation status were valuated in a three-level scale: FV – favorable, U1 – unfavorable/inadequate, U2 – unfavorable/bad. The 2006–2008 monitoring was the first monitoring of habitat types in Poland. It covered 20 habitat types, including grey dunes, raised bogs, various types of grasslands and forests. These were both rare habitat types occurring locally at isolated sites and widely spread habitat types. Generally, the conservation status has been assessed as favorable only at 30% of the investigated localities situated within the Natura 2000 area and at mere 20% of the localities situated outside the Natura 2000 sites. In addition, future prospects have been assessed as inadequate (U1) or bad (U2) at 60% of the localities within the Natura 2000 sites, which suggests that many negative pressures and threats have been identified. Unfavorable (U1 or U2) conservation status was often assessed for semi-natural habitats, whose maintenance requires extensive mowing or grazing. Unfavorable conservation status was also determined for habitat types vulnerable to changes in water conditions (drainage, lowering of groundwater level, lack of regular flooding). The 16 plant species, included in the 2006–2008 monitorning, represented various types of environments. Most of them are extremely rare. The monitoring results showed that almost 40% of the priority species, including some considered as threatened in the country, were in favorable conservation status (FV). Yet, it should be stressed that some of the investigated priority species are connected with relatively well preserved, mountain habitats. Generally, at most localities the status of plant species was assessed as inadequate (35%) or bad (18%). Most often, it was the status of habitat of species that decided about the overall unfavorable conservation status of the species. The data collected allow to indicate these localties, which require special attention and urgent conservation measures. The 2006–2008 monitoring studies contributed much to the knowledge about the occurrence of some species (i.e. Serratula lycopifolia, Galium sudeticum, Cochlearia tatrae, Campanula serrata, Erysimum pieninicum, Liparis loeselii). 180 Chrońmy Przyr. Ojcz. rocznik 65, zeszyt 3, 2009. The 2006–2008 monitoring programme was focused on 20 animal species, including the widely distributed species, still abundant and known from numerous localities (Ophiogomphus cecilia, Triturus cristatus), as well as rare species of very restricted distribution (Phryganophilus ruficollis, Pseudogaurotina excellens), and even species of uncertain occurrence in Poland (Xylomoia strix). The results of the monitoring revwealed the inadequate (U1) conservation status of most species at most localities, which was an effect of inadequate status of both population and habitat of species. For some invertebrates of elusive, cryptic lifestyle (Callimorpha quadripunctaria, Osmoderma eremita, Rosalia alpina) it was impossible to assess unambiguously their population status at certain localities. In the case of 13 animal species, the selection of monitoring localities allowed to draw conclusions on their conservation status at a biogeographical region level. Four of these species (Ophiogomphus cecilia, Phryganophilus ruficollis, Callimorpha quadripunctaria, Marmota marmota) were found to be in favourable conservation status (FV), eight species – in inadequate (U1) and one species (Spermophilus suslicus) in bad (U2). One of the significant results of the 2006–2008 monitoring programme was an improvement of the knowledge of the occurrence of some species (Pseudogurotina excellens, Rosalia alpina, Callimorpha quadripunctaria, Triturus cristatus). The results of the 2006–2008 monitoring will be used for elaboration of the report on the conservation status of habitat types and species of Community interest in 2013. Foremost, these results should be used for planning and implementing conservation measures aimed to improve the conservation status of habitats and species at these localities where it is unfavorable. In view of the limited financial resources for nature conservation, monitoring results could be a useful tool for the optimisation of conservation actions regarding both the subject and place of the planned activity.

Oceniono zmiany w siedlisku i składzie florystycznym zbiorowisk łąkowych występujących w dolinie Samicy. W wyróżnionych zbiorowiskach łąkowo-pastwiskowych w dolinie Samicy stwierdzono znaczny stopień degradacji składu florystycznego runi, na co wskazują: zanikanie części występujących wcześniej zbiorowisk i wykształcenie się nowych jednostek syntaksonomicznych, często zbiorowisk wtórnych z dużym udziałem gatunków ekspansywnych, jak Deschampsia caespitosa, Holcus lanatus, ze znacznym udziałem gatunków z grupy ziół i chwastów charakterystycznych dla zbiorowisk segetalnych i ruderalnych z klas Artemisietea vulgaris, Agropyretea intermedio- repentis czy Stellarietea mediae (10 do 30%) oraz wysokim udziałem gatunków synantropijnych (blisko 85%), szczególnie w zespołach klasy Phragmitetea. Przyczyn zmian degradacyjnych w składzie florystycznym zbiorowisk należy upatrywać w przesuszeniu gleb torfowych i obniżeniu zawartości azotu, a także w ograniczeniu użytkowania łąk i pastwisk w ostatnich latach oraz odłogowaniu sąsiednich pól.

The study evaluated of changes in the habitat and floristic composition of meadow communities occurring in the Samica river valley. A considerable degradation of the sward floristic composition was observed in identified meadow-pasture communities occurring in the Samica river valley. This phenomenon was confirmed partial the disappearance of former plant communities and the development of new syntaxonomic units, frequently secondary communities, with significant proportion of such expansive species as Deschampsia caespitosa, Holcus lanatus, at considerable share of species from the group of herbs and weeds characteristic for segetal and ruderal communities from the Artemisietea vulgaris, Agropyretea intermedio-repentis or Stellarietea mediae classes (10-30%) as well as high proportions of synanthropic species (almost 85%), especially in the associations of the Phragmitetea class. The reasons of observed degradation changes in floristic composition of these communities be suspected in drying of peat soils, in decline of nitrogen content in ought to restriction of meadow and pasture utilization withim recent years as well as the setting aside of adjacent arable land.

W sierpniu ub. roku na zlecenie Głównego Inspektoratu Ochrony Środowiska została rozpoczęta realizacja projektu pt. Monitoring gatunków i siedlisk przyrodniczych ze szczególnym uwzględnieniem specjalnych obszarów Natura 2000. Zakończy się ona we wrześniu 2008 roku. Obecnie realizowany monitoring ma charakter wstępny w stosunku do monitoringu o charakterze docelowym. Głównym jego celami są: poznanie stanu ochrony wybranych gatunków roślin i zwierząt oraz typów siedlisk przyrodniczych, w tym wszystkich oznaczonych w Dyrektywie, jako priorytetowe; przetestowanie, a następnie opracowanie możliwie uproszczonych metod badawczych dostosowanych do wymagań Dyrektywy Siedliskowej; wypracowanie wskazań dla rozwiązań organizacyjnych dla monitoringu o charakterze docelowym. Innym ważnym zadaniem projektu powiązanym z monitoringiem jest sporządzenie projektu raportu dla Komisji Europejskiej w części dotyczącej monitoringu. m.in. w oparciu o wyniki prac badawczych wykonywanych w ramach projektu w 2006 r. Metodyka i zakres badań wynikają z zapisów Dyrektywy Siedliskowej, a za nią z danych, jakie należy podać w raporcie. Dane te są określone w formacie raportu obowiązującym wszystkie kraje członkowskie UE. Wypracowana metodyka ma zapewnić otrzymanie informacji o stanie ochrony poprzez otrzymanie informacji o jej czynnikach/parametrach określonych w Dyrektywie Siedliskowej. O nich z kolei informować będą cechy/wskaźniki wybrane w oparciu o znajomość autoekologii gatunków oraz uwarunkowania ekologiczne siedlisk przyrodniczych. Mają one za zadanie najszybciej informować o zachodzących zmianach. Dodatkowym elementem, które wprowadza Dyrektywa, i co uwzględnić ma metodyka, jest dokonanie oceny stanu ochrony. Wymaga to określenia warunków referencyjnych w sposób dowolny przez dany kraj. Prace badawcze są przeprowadzane na terenie całego kraju na wybranych powierzchniach próbnych głównie na projektowanych specjalnych obszarach ochrony Natura 2000, w tym na terenie Lasów Państwowych, wybranych parków narodowych, krajobrazowych i rezerwatów przyrody.

According to the recommendation of the Chief Inspectorate for Environmental Protection the development of the project entitled Monitoring of species and habitats with the particular focus on the special areas of conservation “Nature 2000”. Was launched in August 2006 within the frame of the State Environmental Monitoring Programme. It will be completed in September 2008. The currently carried out monitoring is of initial and preparatory nature in view of the target one which is to follow. The main objectives of the current monitoring action are: to recognize the conservation status of the selected species of plants and animals as well as the habitat types, including those indicated as priority ones in the Directive; testing and then elaborating the most simplified possible research methods meeting the requirements of the Habitats Directive working out recommendations concerning the organization of the target monitoring. The other important task of the project connected with monitoring is to prepare a draft report for the European Commission in the part concerning monitoring based, among other things, on the results of the research work conducted in 2006. The choice of methodology as well as the range of the research result from the Habitats Directive and furthermore from the obligation to contribute certain data to the report. The data is specified in the reporting format, which is mandatory to all the EU members. The worked out methodology is to provide the necessary information on the conservation status through obtaining the information on its parameters (criterions) specified in the Habitats Directive. Those in turn will be defined by the features/indicators selected on the basis of the knowledge of the autoecology of species and the ecological conditions of the habitats. Their purpose is to inform in the quickest possible way on the undergoing changes. The additional factor introduced by the Directive and to be taken into consideration by the methodology is the requirement of the overall assessments of status conservation. This creates the necessity of defining the individual referrence conditions by each country. The research work is carried out in the territory of the whole country in selected probationary areas, mainly on the projected special areas of habitat preservation Nature 2000, including the State Forest territory, selected national parks, landscape parks and nature reserves.
