“…This is partly in contradiction with some previous studies (see Purtauf et al, 2005 for carabids). On the other hand, Caro et al (2016) suggested that meadows may be poor habitats for carabids. Other studies also reported a negative effect of the percentage of meadow in the landscape on the structure of spider assemblages, as summarized in the review of Prieto-Benítez and Méndez (2011).…”

Despite the role generalist predators may play in biological regulation, the influence of landscape composition in shaping their assemblages remains little studied, especially when landscape interacts with local factors. In this study, we investigated the effects of farming systems along gradients in landscape elements on the structure and composition of carabid and spider assemblages. Twenty pairs of organic vs. conventional spatially-matched fields were sampled in 2013 along increasing percentage covers of organic farming and semi-natural habitats in the landscape. A total of 24241 spiders and 27767 carabids belonging to 120 and 75 species respectively were collected by pitfall traps. Farming systems locally had a strong influence on the community structure (activity-density and species richness) and composition for both spiders and carabids. Structure of spider assemblages was mostly affected by local and landscape factors, whereas that of carabids was more driven by landscape variables and the interaction of the two levels. Spider and carabid community compositions were mostly determined by field farming systems and wood percentage around the field. Our study underlines the importance of landscape context in shaping assemblages of predatory arthropods, and suggests that mechanisms behind the distribution of individual species strongly differ between spiders and carabids.

“…If no significances are given, the results were classified based on a 20% deviation of the individual pairs of the organic from the conventional variant. Abundance is higher (Org +), lower (Org -) in organic farming, or comparable to conventional farming (Org =) a Including three pairwise comparisons according to statistical remarks in Caro et al (2016) for the classification fact that herbicide application usually affects the centers more than the edges (Metcalfe et al 2019;Batáry et al 2012;van Elsen 1989). Field edges can be safer sites for weeds.…”

To what extent does organic farming promote species richness and abundance in temperate climates? A review

The loss of biodiversity in agricultural landscapes has been dramatic over the past few decades with negative trends persisting. Organic farming has received widespread recognition in the scientific and politic fields for its environmental benefits, although the proportion of land cultivated organically is still small and the extent to which organic farming contributes to the promotion of biodiversity is viewed controversially. We present a critical, quantitative review of 98 mainly peer-reviewed papers selected from 801 studies in temperate climate zones published over the period 1990-2017. We quantified differences in the species richness and abundance of selected flora and fauna groups. In total, 474 pairwise comparisons that compared organic and conventional farming systems were considered. Overall, organic farming showed higher species richness or abundance in 58% of the pairs. No differences were found for 38%, 4% indicated negative effects from organic farming. The average (median) species numbers of flora on arable land were 95% higher under organic management as well as 61% higher for seedbank and 21% higher for field margin vegetation. For field birds, the species richness was 35%, and the abundance was 24% higher in organic farming; for insects, the corresponding values are 22% and 36% and for spiders 15% and 55%. Our study underlines that organic farming can play an effective role in acting against the loss of biodiversity. Future research should focus on the combined effects of landscape structures and organic farming, the effect of largescale organic farming, as well as on the correlation of species diversity and production parameters. To meet the systems' representativeness, even more strict selection criteria need to be applied in further analysis.

“…However, the prescriptive nature of this type of scheme is often seen as a barrier to scheme uptake (Wilson and Hart, 2000) and long-term behaviour change (de Snoo et al, 2013). The cost-effectiveness (Ansell et al, 2016), and ecological impact of this type of 'action based' AES, on birds (McHugh et al, 2016;Princé et al, 2012;Sabatier et al, 2012: McHugh et al, 2016, insects (Wood et al, 2015;Caro et al, 2016) and biodiversity (Kleijn and Sutherland, 2003;Kleijn et al, 2006;Fuentes-Montemayor et al, 2011;Wilkinson et al, 2012;Ekroos et al, 2014) is also widely debated in the literature. Many suggest schemes which link payments to the provision of desired environmental outcomes, rather than to prescribed management activities, could represent a more effective way of rewarding farmers for the delivery of "Public Goods" (Matzdorf and Lorenz, 2010;Sabatier et al, 2012;Moxey and White, 2014;Russi et al, 2016).…”

What can management option uptake tell us about ecosystem services delivery through agri-environment schemes?

Agri-environment schemes (AES), currently embedded in EU and UK policies, actively promote 'greening', 'sustainability' and 'ecosystem services' approaches to land management. The funding structures of these policies, however, run counter to this sustainable approach, and create barriers to AES success, primarily through a continued focus on productivity support. In this study, we aim to determine the effectiveness of action-based AES, as a delivery mechanism for ecosystem services, using secondary data analysis techniques to unravel the complexities of AES funding distribution and scheme structure and geographic information systems (GIS) to explore the spatial extent and uptake of AES management options, using Wales, UK as a study area. Our results show 84% of recipients of AES payments receiving <£10k annually, comprising only 35% of the total available funding. 15, out of a total of ~165, management options, accounted for >75% of all advanced level management contracts awarded in both 2015 and 2017. This bias in option uptake, in many cases, positively prevents further deterioration of existing habitat condition through a 'business as usual' approach. However, we argue that the voluntary, over prescriptive nature of the schemes limits management option uptake, negatively impacts on the schemes ability to deliver ecosystem services, and lessens the government's ability to promote long-term behavioural change. If AES are to deliver the '"Public Goods"' that future policy demands, then targeted and adequate levels of funding and a willingness to participate must be combined with greater farmer autonomy and clear outcomes to deliver management options at a landscape scale.
