The effect of hedgerow wild‐margins on topsoil hydraulic properties, and overland‐flow incidence, magnitude and water‐quality

Abstract: Overland and shallow-subsurface flows from agricultural catchments are believed to contribute towards flood-risk and water-quality degradation across the globe. Hedgerows are commonplace agricultural features that may disrupt these rapid hydrological pathways. Research into the hydrological functioning of hedgerows is very limited however, with no field-based quantitative comparison of overland-flows within hedgerows versus other land-uses. This research is the first globally to observe changes in overland-flo… Show more

“…Previous studies have also found woodland catchments to have more permeable soils, with topsoil (< 20 cm) permeability 1.8–8 times greater than that of grazed permanent pasture (Table 4). The median topsoil permeability we measured for pasture sites (1.47 × 10 −4 –2.78 × 10 −4 m·s −1 , 529–1000 mm·hr −1 ) overlap previously reported values for pasture and field margins in Northern England: Wallace and Chappell (2019) reported median topsoil permeability of 21–2794 mm·hr −1 whereas Wallace et al, (2021) reported 317–8780 mm·hr −1 . Hedgerows can also increase permeability, with topsoil permeability 20–30 times higher than pasture (Wallace & Chappel, 2021; Holden et al, 2019).…”

“…Aside from their historical role of crop protection and livestock enclosure, hedgerows have been shown to provide significant above-ground biodiversity benefits within farmed landscapes ( Heath et al, 2017 ; Kremen et al, 2018 ; Litza and Diekmann, 2019 ). More recently, their role in providing wider ecosystem service benefits, such as nutrient interception and protection of surface water quality, flood and drought mitigation, and climate change mitigation has been investigated ( Marshall and Moonen, 2002 ; Bianchi et al, 2006 ; Benhamou et al, 2013 ; Van Vooren et al, 2018 ; Graham et al, 2018 ; Holden et al, 2019 ; Wallace et al, 2021 ; Weninger et al, 2021 ). Therefore, hedgerow planting and management has been encouraged through public AES, such as the Countryside Stewardship, Environmental Stewardship, and Sustainable Farming Incentives in the UK ( DEFRA, 2020 , 2021 ; Natural England and Rural Payments Agency, 2021 ), as well as private sector initiatives ( Tipper and Elliott, 2018 ; CISL, 2018 ; Elliot, 2020 ), where it is increasingly acknowledged that degradation of agricultural ecosystems can lead to operational risks ( Seddon et al, 2020 ).…”

“…Recent studies have started to provide data of hillslope vegetation impacts on overland flow velocity and roughness (Bond et al, 2020; Holden et al, 2008; Wallace et al, 2021). Holden et al (2008) found the mean overland flow velocity for moss ( Sphagnum ) cover was more than 5 times slower than for a bare peat surface.…”
