“…Moreover, they are of high relevance to landscape connectivity (Forman and Baudry, 1984;Baudry et al, 2003;Molnarova, 2008) and also increase landscape heterogeneity (Hoobs, 1992;Quin and Burel, 2002), which not only provides ecological benefits but also has a positive influence on the visual quality of the landscape (Hunziker, 1995;de la Fuente de Val et al, 2006). While some authors connect the definition of hedgerows with their management, which prevents them expanding into adjacent fields (Pollard et al, 1974;Barr and Gillespie, 2000;Baudry et al, 2000), other authors admit more or less spontaneous growth (Forman and Godron, 1986;IDF, 1995).…”

“…25% of linear woody elements were lost in England and Scotland from 1946to 1974, and 14% in Ireland between 1937and 1982(Pointereau and Bazile, 1995Countryside Council for Wales, 1997). Between 1984 and1990, hedgerow length was reduced by 21% in England, by 27% in Scotland and by 25% in Wales (Barr and Gillespie, 2000). After hedgerow removal, many ecological problems arose: soil erosion; wind damage to crops and buildings; an increase in flooding; an increase in crop disease, microclimatic changes, etc.…”

“…The loss of hedgerows has been a key concern since the end of the Second World War, and CS data have proved useful in determining the extent and nature of changes since 1984 (Barr et al, 1991;Barr and Gillespie, 2000;Petit et al, 2003;Norton et al, 2012b) and applying these to policy changes (Barr and Parr, 1994). CS data have contributed to determining policy, for example the Hedgerow Regulations (The Hedgerows Regulations, 1997).…”

Abstract. The Countryside Survey (CS) of Great Britain (GB) provides a unique and statistically robust series of datasets, consisting of an extensive set of repeated ecological measurements at a national scale, covering a time span of 29 years. CS was first undertaken in 1978 to provide a baseline for ecological and land use change monitoring in the rural environment of GB, following a stratified random design, based on 1 km squares. Originally, eight random 1 km squares were drawn from each of 32 environmental classes, thus comprising 256 sample squares in the 1978 survey. The number of these sites increased to 382 in 1984, 506 in 1990, 569 in 1998 and 591 in 2007. Detailed information regarding vegetation types and land use was mapped in all five surveys, allowing reporting by defined standard habitat classifications. Additionally, point and linear landscape features (such as trees and hedgerows) are available from all surveys after 1978. From these stratified, randomly located sample squares, information can be converted into national estimates, with associated error terms.Other data, relating to soils, freshwater and vegetation, were also sampled on analogous dates. However, the present paper describes only the surveys of landscape features and habitats. The resulting datasets provide a unique, comprehensive, quantitative ecological coverage of extent and change in these features in GB. Basic results are presented and their implications discussed. However, much opportunity for further analyses remains.Data from each of the survey years are available via the following DOIs: Landscape area data 1978: https://doi.org/10.5285/86c017ba-dc62-46f0-ad13-c862bf31740e, 1984: https://doi.org/10.5285/b656bb43-448d-4b2c-aade-7993aa243ea3, 1990: https://doi.org/10.5285/94f664e5-10f2-4655-bfe6-44d745f5dca7, 1998: https://doi.org/10.5285/1e050028-5c55-42f4-a0ea-c895d827b824, and 2007: https://doi.org/10.5285/bf189c57-61eb-4339-a7b3-d2e81fdde28d; Landscape linear feature data 1984: https://doi.org/10.5285/a3f5665c-94b2-4c46-909e-a98be97857e5, 1990: https://doi.org/10.5285/311daad4-bc8c-485a-bc8a-e0d054889219, 1998: https://doi.org/10.5285/8aaf6f8c-c245-46bb-8a2a-f0db012b2643 and 2007: https://doi.org/10.5285/e1d31245-4c0a-4dee-b36c-b23f1a697f88, Landscape point feature data 1984: https://doi.org/10.5285/124b872e-036e-4dd3-8316-476b5f42c16e, 1990: https://doi.org/10.5285/1481bc63-80d7-4d18-bcba-8804aa0a9e1b, 1998: https://doi.org/10.5285/ed10944f-40c8-4913-b3f5-13c8e844e153 and 2007: https://doi.org/10.5285/55dc5fd7-d3f7-4440-b8a7-7187f8b0550b.

“…South West Devon, also known as the South Hams, is a region where, due to its pastoral character, many hedgerows have persisted during the twentieth century (Barr and Gillespie 2000). South West Devon stretches from the fringes of Plymouth on the west to Torquay on the east.…”

“…We did not have any data or information on the current state of the hedgerows in the case study area but their location. Hedgerow density, or total length of hedgerows in a given area is more often used as an indicator for the current state of the hedgerows as their disappearance is one of the major threats (Barr and Gillespie 2000;Van der Zanden et al 2013). The assumed correlation between hedgerow quality and density was supported by the participants at the stakeholder workshop.…”

Context Hedgerows are typical landscape features of high environmental and cultural value that often have been sacrificed for agricultural intensification and scale enlargement. Objectives We studied the dynamics of hedgerow quality over time in a case study area renowned for its hedgerow landscapes: South West Devon (UK) answering the following research questions: (1) how does the imperative of scale enlargement affect hedgerow quality? and (2) to what extent can cultural landscape degradation be countered by targeted policies? Methods We applied an agent-based modeling approach, parameterized with a site specific survey, to explore and discuss outcomes of future landscape change with stakeholders and co-designed preferred scenarios of landscape change during a workshop. Results Outcomes suggested that in the case-study area, scale enlargement has a negative effect on hedgerow quality when agri-environment scheme subsidies (AES) are low. In contrast, if the level of AES enrollment is high, scale enlargement can have a positive effect on hedgerow quality, as large holders are more likely to enroll for AES. Stakeholders acknowledged the need for agricultural intensification, but at the same time valued biodiversity and environmental value of the landscape in South West Devon. Conclusion Current AES are able to retain a decent hedgerow quality. With lower AES, scale enlargement can have an invigorative effect on hedgerow quality as land managers of larger farms will be less likely to join AES As an addition to AES, harvesting wood fuel from coppiced hedgerows appears a promising way to incentivize rejuvenating hedgerow management without governmental subsidies.
