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. 相似文献

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. 相似文献

Private land often encompasses biodiversity features of high conservation value, but its protection is not straightforward. Commonly, landowners’ perspectives are rightfully allowed to influence conservation actions. This unlikely comes without consequences on biodiversity or other aspects such as economic considerations, but these consequences are rarely quantitatively considered in decision-making. In the context of boreal mire protection in Finland, we report how acknowledging landowners’ resistance to protection changes the combination of mires selected to conservation compared to ignoring landowners’ opinions. Using spatial prioritization, we quantify trade-offs arising between the amount of landowners’ resistance, protected biodiversity, and financial costs in different conservation scenarios. Results show that the trade-offs cannot be fully avoided. Nevertheless, we show that the systematic examination of the trade-offs opens up options to alleviate them. This can promote the evaluation of different conservation policy outcomes, enabling better-informed conservation decisions and more effective and socially sustainable allocation of conservation resources.Supplementary InformationThe online version contains supplementary material available at 10.1007/s13280-021-01530-0. 相似文献

Toronto is among the fastest-growing urban regions in North America. Regional efforts to preserve rural landscapes and remnant
habitat have had variable success. In the 1990s, significant conflict emerged over proposals to build large housing developments
on portions of the Oak Ridges Moraine, a 160-km stretch of environmentally sensitive land along the city’s northern edge.
After years of planning conflict, Ontario’s provincial government created the Oak Ridges Moraine Conservation Plan, an Act
of the Ontario Legislature. The Plan represents a dramatic change in Ontario’s approach to conservation planning. We examine
the development and implementation of the Conservation Plan as an example of environmental planning policy in a complex urban
setting. Data from interviews with policy actors, planning agency documents, and geospatial sources are used to construct
an analysis and discussion of the Plan and its implementation. From a policy research perspective, the evolution and implementation
of the Plan require analysis and monitoring to better understand how such approaches can best be implemented. The Conservation
Plan marks a change in policy in Ontario, and the implementation process highlights challenges in putting conservation plans
into practice. 相似文献

Illegal wildlife trade enforcement is a cornerstone conservation strategy worldwide, yet we have a limited understanding on its social impacts. Using Chinese online wildlife seizure news (2003–2018), we evaluated the interactions among enforcement operations, news frequency, and social engagement (i.e., whistle-blowing) frequency. Our results showed that intensive enforcement operations, which commenced after 2012, have social impacts by increasing the frequency of all seizure news significantly by 28% [95% Confidence Interval (CI): 5%, 51%] and those via whistle-blowing by 24% [95% CI: 2%, 45%], when compared to counterfactual models where possible confounding factors were accounted for. Furthermore, we revealed the potential interaction between enforcement seizure news with and without social engagement, and the consequential social feedback process. Of the species identified from ‘whistle-blowing’ news, up to 28% are considered as high conservation priorities. Overall, we expanded our understanding of the enforcement impacts to social dimensions, which could contribute to improving the cost-effectiveness of such conservation efforts.Supplementary InformationThe online version contains supplementary material available at 10.1007/s13280-021-01686-9. 相似文献
