TL;DR: A combination of a simple environmental matching approach to locate extant populations in the state of Sao Paulo and then a more complex ecological niche modeling approach to predict distribution of the species over a broader area is used.

TL;DR: In this paper, a set of management objectives for the wetland natural reserve is proposed, which include protecting the ecosystem and the waterfowl resources in the new wetland, renewing biodiversity and maintaining the function of the ecosystem.

TL;DR: It is proposed that a SPAD-502 chlorophyll meter would provide valuable information when monitoring life cycle changes and intraspecific variation in endangered plant populations, whereby, destruction of plants to obtain this information is impractical.

TL;DR: In this article, the authors investigated the attitudes of 108 Swiss people to improved field margins (IFMs) directly in the field and found that the more species-rich an IFM was perceived to be, the more it appealed to them.

TL;DR: It is concluded that it is not possible to fix valid thresholds for all groups owing to their scarcity and fragmentation as this would risk overestimating the danger faced by the less-vagile species at the expense of the more widely dispersed ones.

TL;DR: In this paper, the authors explored in a GIS how the water-landscape may change for water-dependent grazers under different surface-water management policies and climatic conditions in the Kruger National Park, South Africa.

TL;DR: The lack of comprehensive methodologies for providing economic valuation for biodiversity and ecosystem services, the results of which can be easily communicated to policy and decision-makers, has hampered efforts to protect, maintain and enhance habitats and species.

TL;DR: In this paper, the authors propose two models for habitat banking in the UK, which could also be adapted for use elsewhere in Europe, and argue that the most effective way to address doubts surrounding the habitat banking concept would be through one or a number of pilot projects.

TL;DR: In this article, the scope for efficiency gains in geopolitical coordination between the European Union member states was examined, using data on the distribution of 2676 plant species and 181 mammal species and the cost of reducing agricultural production as an illustrative measure of conservation cost.

TL;DR: In this paper, the authors explore the process of non-analogous communities (NACs) formation, with reference to the key processes of immigration and extinction and the potential influence of landscape pattern in the context of a metacommunity framework.

TL;DR: It is concluded that adequate agri-environmental policy should not focus only on lowland meadows, even if the highest meadow bird diversity is often found there, because whinchat Saxicola rubetra populations now rarely breed at altitudes below 1,000 m except in flooded alluvial plains.

TL;DR: Overall, seed sowing can facilitate restoration of impoverished semi-natural grasslands where the species richness has decreased due to insufficient management and when local seed sources are no longer present.

TL;DR: In this article, the authors used the community of passerines and woodpeckers as a target group for the conservation management of Pindos National Park (NW Greece) and conducted bird point counts twice during springtime in 72 plots that represented the main vegetation types (16 sites).

TL;DR: In this paper, the authors examined the impact of a tidal barrage across the Severn Estuary in the UK and found that significant detrimental effects on nature conservation are likely and some of the functional changes also have important implications for flood defence structures around the estuary and its tributaries.

TL;DR: In this article, the authors used the Travel Cost (TCM) and Contingent Valuation Methods (CVM) to estimate the value of an endangered species and determined the break-even point in the allocation of funds targeted at protection at the regional level and performed a cost benefit analysis of conservation efforts on a national level.

TL;DR: In this article, the authors analyze the obstacles preventing the implementation of the EA in two case study countries, Canada and Germany, and reveal that the EA is faced with a wide range of barriers and its implementation seems to be stuck in the political arena, not reaching the practical level.

TL;DR: In this article, the authors investigated the composition and diversity of the floodplain meadows of the alluvial plain of a 40 km river reach in the Netherlands and concluded that the need for dynamic flooding processes in the creation of habitat and in the dispersal and recruitment of dry river grasslands in newly generated habitat after two consecutive flood peak periods of the mid nineties and the beginning of this century.

TL;DR: In this paper, the effects of the cessation of agro-sylvo-pastoral activities on Centaurea horrida Badaro, a very rare sea-cliff plant, endemic to North-Western Sardinia (Italy) and listed by the IUCN as vulnerable, were investigated.

TL;DR: The results show that P. nigra is more abundant in Switzerland than hitherto thought and a low frequency of gene introgression is detected.

TL;DR: In this paper, the authors present an alternative way of unveiling the anthropogenic processes that are responsible for shaping tree resource distribution at the micro-level, thus providing information about the microlevel dynamics of tree resources distribution and use patterns which policy makers and resource planners could consider when making decisions about community-based forest and woodland resource conservation.

TL;DR: The processes for making decisions on objectives and management actions were identified in nine easily available management planning guides, all aimed at UK protected sites, and compared, and it is found that no two guides recommend identical processes.

TL;DR: Nine easily available management planning guides, all aimed at UK protected sites (SSSI, Natura 2000, Ramsar, etc.), were compared and concerns are raised about the consistency of plan preparation for protected sites across the UK.
