There have been raised several questions about saving natural, historical and cultural values of the territory of national park “Dnister river canyon” in this article. Also, this work highlights historical and natural conditions of canyon’s formation. Landscape, aesthetic and recreational resources of Dnister river canyon are incomparable among the territory of Ukraine. That is why it is important to save it from massive anthropogenic pressure. On of the stresses is a planned construction of upper Dnister river cascade hydropower station on the protected territory of national park “Dnister river canyon”.

Abstract Gala Lake National Park that has an international importance is one of the most important wetland ecosystems for Turkey. As same as many aquatic habitats, Gala Lake is under a significant anthropogenic pressure originated from agricultural activities conducted around the lake and from industrial discharges by means of Ergene River. The aim of this study was to evaluate the sediment quality of Gala Lake and Irrigation Canal by investigating some toxic element accumulations (As, B, Ni, Cr, Pb, Cd, Zn and Cu) from a statistical perspective. Pearson Correlation Index (PCI) and Factor Analysis (FA) were applied to detected data in order to determine the associated contaminants and effective factors on the system. Potential Ecological Risk Index (RI) and Biological Risk Index based sediment quality guidelines (mERM-Q) applied to detected data in order to assess the ecological and biological risks of heavy metals in the ecosystem. Also Geographic Information System (GIS) technology was used to make visual explanations by presenting distribution maps of investigated elements. According to the results of PCI, significant positive correlations were recorded among the investigated toxic elements at 0.01 significance level. According to the results of FA, two factors, which were named as “Agricultural Factor” and “Industrial Factor”, explained 86.6% of the total variance. According to the results of Potential Ecological Risk Index, cadmium was found to be the highest risk factor and according to results of Biological Risk Index, nickel and chromium were found to be the highest risk factors for Gala Lake and Irrigation Canal. As a result of the present study, it was also determined that heavy metal contents in sediments of Gala Lake National Park reached to critical levels and the system is intensively under effect of agricultural and industrial originated pollution.

Cyclic fluctations in the popu]ation density of rnicrotine rodents have been known since antiquity. However, factors responsible for this phenomenon are not known. The objectives of this long term study are essentially threefold: 1. characterize those environmental variables that might affect Microtus montanus in different seasons of the year; 2. record the growth, maturation and reproductive activity of the voles under natural conditions; and 3. determine the maturational, as well as, the seasonal pelage changes of these rodents. The data resulting from the execution of the above objectives would be correlated in an attempt to determine the causes undedying the multiannual fluctuations in the population density of these microtine rodents in Grand Teton National Park.

The gardens of the two settlements in the Lamington National Park – Binna Burra and O'Reillys – are cultural landscapes in a much loved area of the Scenic Rim of Queensland's border with NSW. The concept of cultural landscapes in the World Heritage and national contexts was introduced at the 2002 Australian Garden History Society conference in Hobart. This paper examines the evolution of two gardens within a national park – one evolving from a farm and one designed to accompany a rainforest holiday centre – and the acceptance of cultural values in natural areas.

O Parque Nacional dos Campos Gerais (PNCG) detém áreas de campos de altitude sob forte pressão antrópica, com a expansão das atividades agrícolas, pecuária, silvicultura e visitação turística desordenada. Devido ao impacto gerado, existe uma tendência à diminuição da riqueza específica, através da seletividade de espécies. Este trabalho analisa a resposta das comunidades campestres em termos de composição de espécies aos impactos de pastejo, roçada e pisoteio humano. Em quatro estações de coleta, foram determinados 107 táxons distribuídos em 23 famílias botânicas. As famílias com maior riqueza específica foram Asteraceae e Poaceae, ambas com 24 táxons, e Fabaceae, com 14 táxons. A riqueza específica variou de 27 a 75 espécies, com maior riqueza na estação não pastejada nem roçada, apenas visitada por turistas. O levantamento mostrou que, apesar da pressão antrópica, as áreas estudadas exibem considerável riqueza específica quando comparadas a outros trabalhos na região, mantendo ainda seu potencial biótico dinâmico. Floristicamente, os impactos gerados por gado ou por manejo com roçadeira se equivalem. Seis gêneros têm potencial para serem utilizados como bioindicadores de áreas conservadas: Croton, Galactia, Periandra, Cuphea, Pavonia e Commelina, mas há necessidade de ampliação das áreas estudadas para estabelecer mais claramente seu valor de bioindicação.Palavras-chave: Campo nativo; Campos Gerais; área impactada; pastejo; visitação turística. AbstractThe species diversity in native grassland areas that are under impact of tourism and grazing at Campos Gerais National Park, Parana, Brazil. Campos Gerais National Park (PNCG) has areas of grassland under high anthropogenic pressure, as expansion of agricultural activities, livestock, forestry and disorderly tourism. Due to these impacts, there is a tendency to decrease local biodiversity by selection of more resistant species. This paper focuses the grassland community answers to mowing, grazing and tourism. In four sampling sites it was determined 107 taxa belonging to 23 botanic families. The main families are Asteraceae (24 taxa), Poaceae (24 taxa) and Fabaceae (14 taxa). Species diversity varied from 27 to 75 species. In relation to species number, non-grazed areas presented greater diversity than other ones; it points to that touristic visitation may cause lower impact than grazing or mowing. In spite of the anthropogenic factors, the focused sites presented high specific diversity in relation to related areas. In relation to species diversity, grazing or mowing are equal. Six genera presented potentiality as bioindicators of preserved environments: Croton, Galactia, Periandra, Cuphea, Pavonia, and Commelina, although more sample areas are necessary to reliable results.Keywords: Grasslands; Campos Gerais; impacted area; grazing; touristic activities.

Gasoducto Nor Andino is a 1,100 km long natural gas pipeline which runs through one of the most critical environmental and social areas of Argentina and Chile. The area is inhabited by aboriginal communities that face a progressive deterioration of their cultural values and traditional customs. The beginning of the construction of Gasoducto Nor Andino triggered a strong reaction in the local communities and environmental organizations such as Greenpeace. Such reaction soon extended throughout the country, generating a strong debate as to the value of Economic & Technological Progress vs Environmental Conservation. All the problems were successfully solved by actions conducted in accordance with the Company’s ethical values. The different stakeholders involved were called together and agreements were implemented with nongovernmental organizations (NGOs), such as Greenpeace, representatives of the aboriginal communities, local and environmental authorities (National Park Administration, Environmental Secretariat of Salta Province, etc.). This paper describes the non-traditional and innovative actions taken to solve the problems and the remarkable results achieved.

Abstract During geobotanical studies in the north-eastern border of hemi-boreal zone, in Valday (NW Russia), rare eutrophic deciduous forests dominated by oak Quercus robur were observed. A comparison of these forests with the model of European deciduous forest in Białowieża National Park (NE-Poland) indicates a great similarity. Therefore, eutrophic deciduous forests in Valday can be classified to the Querco-Fagetea class, the Fagetalia sylvaticae order and to the Capinion betuli alliance, despite the absence of hornbeam Carpinus betulus in the region. Rarity of eutrophic deciduous forests in Valday region results probably from strong anthropogenic pressure in the past.

1 RÉSUMÉ La présente étude a pour but d’étude la dynamique des peuplements ligneux dans le Parc National de Manda. Elle vise à déterminer les caractéristiques structurales, la composition spécifique et la régénération des peuplements ligneux. Quatre sites ont été implantés depuis 2012. Nous avons procédé à la caractérisation des peuplements ligneux par des relevés dendrométriques. La flore ligneuse dans l’ensemble des sites est riche de 87 espèces reparties en 56 genres et 22 familles. Les sites 1 et 2 ont des effectifs plus élevés en 2019 comparativement en 2014 et en 2012. Une forte régénération s’est effectuée durant l’année 2019. Contrairement aux sites, 1 et 2, les sites 3 et 4 présentent pour l’année 2019 une forte baisse des effectifs de jeunes plants. Ces jeunes plants sont très sensibles non seulement à la disponibilité des ressources en eau pour franchir la saison sèche mais aussi à l’intensité et à la fréquence de passage des feux. Les résultats ont permis de noter que la densité moyenne entre 2012 et 2014 s’est accrue et à partir de 2014 elle s’est stabilisée. La surface terrière par hectare est, en moyenne de 10,12 m2/ha pour 2012 ; 11,16 m2/ha pour l’année 2014 et de 11, 65 m2/ha pour l’année 2019. Pour l’ensemble des sites expérimentaux, on évalue le volume moyen de bois sur pieds à 12,31 m3/ha en 2012, à 12,46 m3/ha en 2014 et 12,08 m3/ha en 2019. Ces valeurs indiquent que les variations de volume moyen de bois sur pieds sont très faibles pour les sites pris dans leur ensemble. Les résultats obtenus, montrent aussi que 8 espèces se situent dans un processus d’évolution régressive et 4 autres dans un processus d’évolution progressive. La structure des peuplements ligneux n’a pas beaucoup évolué en 8 ans mais, elle apparaît fortement tributaire de la topographie et de la pression anthropique. ABSTRACT Dynamic of the woody populations in the National Park of Manda, to the south of Chad The purpose of this study is to study the dynamics of woody stands in the Manda National Park. It aims to determine the structure, specific composition and regeneration of woody stands. Four sites have been established since 2012. We have characterized the woody stands by dendrometric surveys. The woody flora in all sites is rich in 87 species divided into 56 genera and 22 families. Sites 1 and 2 have higher numbers in 2019 compared to 2014 and 2012. Strong regeneration took place in 2019. Unlike sites 1 and 2, sites 3 and 4 present for the year 2019 a sharp decline in the number of young plants; these seedlings are very sensitive not only to the availability of water resources to cross the dry season but also to the intensity and frequency of fire. The results showed that the average density between 2012 and 2014 increased and from 2014 it stabilized. The basal area per hectare is, on average, 10.12 m2 / ha for 2012; 11.16 m2 / ha for the year 2014 and 11, 65 m2 / ha for the year 2019. For all the experimental sites, the average volume of standing timber is estimated at 12.31 m3/ ha in 2012, 12.46 m3 / ha in 2014 and 12.08 m3 / ha in 2019. These values indicate that variations in average volume of standing timber are very low for sites taken as a whole. The results obtained also show that 8 species are in a process of regressive evolution and 10 in a process of gradual evolution. The structure of woody stands has not changed much in 8 years, but it appears highly dependent on topography and anthropogenic pressure.
