Planning in the countryside

The author considers the present greater awareness of the needs of the countryside brought about through public debate of the issues involved. The nature of countryside policies is considered and recent developments described. The paper concludes that much more positive planning is being undertaken to conserve the countryside, whilst allowing rural development to take place.     

Modelling interactions between scavenger behaviour and farming practices: Impacts on scavenger population and ecosystem service efficiency

Long term conservation of ecosystem services requires a deep understanding of their basic processes and the development of tools to assess the effects of human practices on their efficiency. As an example of recycling service, we focus on the consumption of livestock carcasses by obligate scavengers, taking the case of vultures which face a dramatic decline worldwide. We investigate whether maintaining this recycling service through individual feeding stations called light feeding stations in contrast to aggregated resource on heavy feeding stations can meet the double objectives of vulture conservation and service efficiency. We built a spatially explicit multi-agent model to investigate the long term effects of livestock farmers practices on both the recycling service efficiency for farmers and vulture population carrying capacity including: (i) carcass disposal practices that drive the quantity and spatial distribution of resources for vultures and (ii) temporal distribution of livestock mortality due to economic choices that drive the dynamics of resources for vultures. In addition, we examine various scenarios related to vulture feeding behaviour - i.e. central place vs. random foraging and contest vs. scramble intraspecific competition - that may play a role in the vulture carrying capacity and recycling service efficiency. When accounting for vulture central place foraging, we found that favouring the use of light feeding stations instead of heavy feeding station does not affect vulture population carrying capacity and increases the number of farmer for which vulture service is optimal. The increase of light feeding station users poorly affects the number of farmers for which vulture service is optimal in contrast to results obtained with a vulture random foraging behaviour. Both of the recycling service efficiency and the vulture carrying capacity vary with the kind of intraspecific competition and with the seasonal distribution of livestock mortality. Livestock mortality distributions with a seasonal peak of mortality result in a mismatch between vulture food requirement and farmers needs for carcass removal. Finally we raise several points on the relevance of light feeding stations as a sustainable management for vulture conservation and for the recycling service and discuss the potential implications of seasonal scarcity of resources due to farming economic constraints.     

Ecological effects of cultivation on the machair sand dune systems of the Outer Hebrides, Scotland

The machair sand dune systems of the Outer Hebrides of Scotland are a unique habitat, which is rare within both a global and European context. Unusually, the machair habitat also represents an agricultural resource that is very important to the Hebridean people, having been subject to both grazing and cultivation throughout the historical period. Following designation as an Environmentally Sensitive Area (ESA) in 1988, the machairs of South Uist have been studied with the aim of understanding the links between agricultural practice and their plant community and ecosystem dynamics. This research focused primarily on the effects of cultivation practices and their role in maintaining plant species richness and community and ecosystem stability. Within two carefully selected areas, the successional plant communities of machair at different stages of recovery following ploughing and cultivation of cereals and potato patches or ‘lazy beds’ were identified at both a macro- and micro-level. Investigations of the vegetation recovery processes on turves taken from newly ploughed land indicated that the initial stages of recolonization are characterized primarily by rapid vegetative reproduction and growth, although re-vegetation by seeds is also an important factor. The implications of these findings for the long-term management of machair plant communities are discussed and in particular the need to maintain old cultivation practices such as shallow ploughing. The need for more detailed research into both seed banks and seed rain and into processes of vegetative reproduction is stressed.     

What determines the success and failure of environmental crowdfunding?

Online crowdfunding can help address the perennial financial shortfalls in environmental conservation and management. Although many online crowdfunding campaigns fail to collect any funds due to not achieving their targets, little is known about what drives success. To address this knowledge gap, we applied a mixed-methods approach to data from 473 successful and failed campaigns hosted on the online crowdfunding platform Readyfor. We found that fundraising performance varied by topic, with campaigns on pet animal management outperforming those focussed on landscape management and sustainable use. We also found that marketing strategies associated with online findability and increased reach through social networks, increased fundraising success. However, the existence of other environmental campaigns running simultaneously, reduced the chance of success, which implies that the selecting popular topics does not always increase the likelihood of success due to increased competition. Wider applications of marketing could enhance the ability of environmental crowdfunding campaigns to raise funds.Supplementary InformationThe online version contains supplementary material available at 10.1007/s13280-021-01522-0.     

The Effectiveness of Asulam for Bracken (<Emphasis Type="Italic">Pteridium aquilinum</Emphasis>) Control in the United Kingdom: A Meta-Analysis

Bracken (Pteridium aquilinum) is a major problem for livestock-based extensive agriculture, conservation, recreation, and game management globally. It is an invasive species often achieving dominance to the detriment of other species. Control is essential to maintain plant communities such as grassland and lowland heath or if extensive grazing by domestic stock, particularly sheep, is to be viable on upland margins. Bracken is managed primarily by herbicide application or cutting but other techniques including rolling, burning, and grazing are also utilized. Here we evaluate the evidence regarding the effectiveness of asulam for the control of bracken. Thirteen studies provided data for meta-analyses which demonstrate that application of the herbicide asulam reduces bracken abundance. Subgroup analyses indicate that the number of treatments had an important impact, with multiple follow-up treatments more effective than one or two treatments. Management practices should reflect the requirement for repeated follow-up. There is insufficient available experimental evidence for quantitative analysis of the effectiveness of other management interventions, although this results from lack of reporting in papers where cutting and comparisons of cutting and asulam application are concerned. Systematic searching and meta-analytical synthesis have effectively demonstrated the limits of current knowledge, based on recorded empirical evidence, and increasing the call for more rigorous monitoring of bracken control techniques. Lack of experimental evidence on the effectiveness of management such as rolling or grazing with hardy cattle breeds contrasts with the widespread acceptance of their use through dissemination of experience.     

Identifying areas of high herpetofauna diversity that are threatened by planned infrastructure projects in Spain

A major task related to conservation is to predict if planned infrastructure projects are likely to threaten biodiversity. In this study we investigated the potential impact of planned infrastructure in Spain on amphibian and reptile species, two highly vulnerable groups given their limited dispersal and current situation of population decline. We used distribution data of both groups to identify areas of high herpetofauna diversity, and compared the locations of these areas with the locations of the planned road, high-speed train railway and water reservoir network. Four criteria were used for this identification: species richness, rarity, vulnerability, and a combined index of the three criteria. From a total of 1441 cells of 20 x 20 km, areas of high diversity were defined as those cells whose ranked values for the different criteria included either all species or all threatened species. The combined index provided the smallest number of cells needed to retain all threatened species (1.7 and 2.6% of the cells for amphibian and reptile species, respectively). Coincidences between these high diversity areas and cells including planned infrastructures-denominated 'alert planning units'-were 35.4% for amphibians and 31.2% for reptiles. Mitigation of the potential impacts would include actions such as barriers to animal access to roads and railways and ecoducts under these constructions. Our approach provides conservation authorities information that can be used to make decisions on habitat protection. A technique that identifies threats to herpetofauna before they occur is also likely to improve the chance of herpetofauna being protected.     

Conservation tillage: best management practice for nonpoint runoff

Decisionmakers are in the process of selecting remedial measures for controlling nonpoint pollution runoff. Conservation tillage (CT) is being looked to as one of the major recommended practices. Many different systems exist and vary in the amount of crop residue left and soil roughness produced. Therefore, varying results occur in terms of yield and potential water quality impacts. Differences vary with type of tillage system, soils, geographic region, and the farmer's management. The purpose of this review is to provide material to decisionmakers that points out the assets and liabilities of the various CT systems. Tillage effects on soil characteristics and plant growth are presented and include a discussion of soil moisture and temperature, weed and insect control, nutrient availability, and yields. Water quality aspects are addressed through a discussion of the effects CT systems have on sediment, water, pesticide, and phosphorus loss.This work was supported by the Soil Science Department, College of Agriculture and Life Sciences, University of Wisconsin-Madison, and the U.S. Environmental Protection Agency, Region V, Chicago, Illinois.
