“…Forests have not been disturbed as much as open localities and therefore there has been less of a decline in the number of suitable localities for E. helleborine. According to Rewicz et al (2015), there are big differences between natural and anthropogenic populations of E. hellebrine in the amount of seed …”

Decline in wet grasslands, which in the past resulted particularly from the intensification of agriculture, was accompanied by the loss of a lot of populations of organisms, including protected and endangered species of plants and animals associated with these habitats e.g. terrestrial orchids. The survival of populations of many species of European orchids is strongly dependent on appropriate site management, especially regular mowing or grazing. In addition, humans can negatively affect the persistence of orchid populations in various ways, such as conversion of orchid meadows into building areas, dams, roads etc. or the intensive use of fertilizers and contamination of areas by fertilisers from nearby fields. Comparison of historical data with the present distribution of orchids can reveal a lot about the main reasons for the decline in this endangered group of plants. Here we present an extensive study of the persistence of 192 historical orchid sites in South Bohemia, with particular reference to the 5 commonest species of orchids, Anacamptis morio, Dactylorhiza majalis, Epipactis helleborine, Epipactis palustris and Platanthera bifolia. We show that the most abundant species at the sites studied was Dactylorhiza majalis. E. palustris, A. morio and P. bifolia are currently not present at any of the historical localities for these species. Considering more recent history, the situation regarding orchid localities in South Bohemia is not critical, but the fate of these species should be closely monitored. The majority of this loss is due to the cessation of mowing of the sites. Thus more attention should be paid to the management of the existing sites. During this study, some new sites were discovered.Keywords: extinction, meadows, terrestrial orchids, South Bohemia (Kull 2002), but present methods of mowing does not necessarily result in the persistence of orchid populations (Tamm 1991). Effect of management on orchid populations is best assessed by long-term monitoring (Inghe and

Background. Epipactis helleborine is an Eurasian orchid species which prefers woodland environments but it may also spontaneously and successfully colonise human-made artificial and disturbed habitats such as roadsides, town parks and gardens. It is suggested that orchids colonising anthropogenic habitats are characterised by a specific set of features (e.g.: large plant size, fast flower production). However, as it is not well known how pollinator diversity and reproductive success of E. helleborine differs in populations in anthropogenic habitats compared to populations from natural habitats, we wanted to compare pollinator diversity and reproductive success of this orchid species between natural and anthropogenic habitat types. Methods. Pollination biology, reproductive success and autogamy in populations of E. helleborine from anthropogenic (roadside) and natural (forest) habitats were compared. Eight populations (four natural and four human-disturbed ones) in two seasons were studied according to height of plants, length of inflorescences, as well as numbers of juvenile shoots, flowering shoots, flowers, and fruits. The number and diversity of insect pollinators were studied in one natural and two human-disturbed populations. Results. Reproductive success (the ratio of the number of flowers to the number of fruits) in the populations from anthropogenic habitats was significantly higher than in the natural habitats. Moreover, plants from anthropogenic habitats were larger than those from natural ones. In both types of populations, the main insect pollinators were Syrphidae, Culicidae, Vespidae, Apidae and Formicidae. With respect to the type of pollinators' mouth-parts, chewing (39%), sponging (34%) and chewingsucking (20%) pollinators prevailed in anthropogenic habitats. In natural habitats, pollinators with sponging (55%) and chewing mouth-parts (32%) dominated, while chewing-sucking and piercing-sucking insects accounted for 9% and 4% respectively. Discussion. We suggest that higher reproductive success of E. helleborine in the populations from anthropogenic habitats than in the populations from natural habitats may result from a higher number of visits by pollinators and their greater species diversity, but also from the larger size of plants growing in such habitats. Moreover, our data clearly show that E. helleborine is an opportunistic species with respect to pollinators, with a wide spectrum of pollinating insects. Summarising, E. helleborine is a rare example of orchid species whose current range is not declining. Its ability to make use of anthropogenically altered habitats has allowed its significant spatial range expansion, and even successful colonisation of North America.

“…chemical and biological properties of soils found on anthropogenic landscapes are generally less favorable than those in soil found on natural landscapes [46]. For instance, urban soils are characterized by modified soil organism activity and modified soil temperature regimes, elevated soil reaction (pH), greater nutrient amounts and availability to plants, higher calcium levels, more rocks, greater decomposition rates, less accumulated organic matter, and compacted mixtures of anthropogenic materials compared with local remnants of the natural ecosystems [47].…”

We are in the Anthropocene and recent studies have revealed that conventional land management strategies diminished natural landscapes and created anthropogenic ones. The classification and characterization of landscapes, therefore, provide a mechanism for quantifying anthropogenic changes to the landscape systems in the Anthropocene. This study was aimed at classifying and characterizing landscapes in the territory of Adilabad District, Telangana, Deccan region, India, which was selected as the area of case study. It was a multi-method approach, where ecogeographic and environmental data were gathered using user/visual-based approach, while socio-economic data were gathered through direct observations, interviews, focus group discussions, questionnaires and literature surveys. The data were analyzed using descriptive and inferential statistics. The study was undertaken by National Bureau of Plant Genetic Resources, Regional Station, Rajendranagar in collaboration with Vegetable Research Station, Rajendranagar during 2010-2012. In the District, a very wide range of land use types was observed. In the last 60 years, the District's landscape has undergone a remarkable transformation and fragmentation as a consequence of anthropogenic activities like deforestation, agriculture expansion, intensive agriculture, transport infrastructure, urbanization, trade, tourism and recreation. The results revealed that there is a growing body of evidence supporting the hypothesis that the geographical space, which is a mosaic of natural and anthropogenic landscapes (semi-natural and artificial landscapes), is limited in the District. Hills, valleys, forests, rivers, streams, waterfalls and lakes were certain natural landscapes with little or no human impact found in the District. Traditional land management strategies including burning and clearing practiced by indigenous tribal communities, the na- 2/38OALib Journal tive inhabitants of the area, have diminished natural landscapes and created semi-natural and artificial landscapes. Complex interactions between humans and nature resulted in a rich amalgam of anthropogenic landscapes and new ecosystems and habitats were created in urban, rural and tribal areas. The artificial landscapes are classified into three main categories: urban, rural and tribal landscapes based on the dominant human societies inhabiting them in the District. Our study identifies the same importance to all types of landscapes: thus natural, semi-natural, tribal, rural, urban landscapes are the key factors in cultural identity of the District. Our work on landscape analysis as a tool for the strategic assessment of the case study area enabled us to use user/visual-based approach based on the assessment of the visual fields of the District.
