Key messages

One replicated controlled trial showed that hedges managed under the Scottish Rural Stewardship scheme do not attract more nest-searching or foraging queen bumblebees in spring than conventionally managed hedgerows.

 

About key messages

Key messages provide a descriptive index to studies we have found that test this intervention.

Studies are not directly comparable or of equal value. When making decisions based on this evidence, you should consider factors such as study size, study design, reported metrics and relevance of the study to your situation, rather than simply counting the number of studies that support a particular interpretation.

Supporting evidence from individual studies

  1. A replicated, controlled trial of the Rural Stewardship agri-environment scheme on five farms in Scotland found that hedgerows dominated by hawthorn Crataegus monogyna or blackthorn Prunus spinosa were less attractive than field margins or grasslands to nest-searching queen bumblebees Bombus spp. in April and May (Lye et al. 2009). There was no significant difference in numbers of foraging or nesting queens between hedgerows managed under the agri-environment scheme (winter cut every three years, gaps filled, vegetation below unmown and unsprayed) and conventionally managed hedgerows. The study took place before the woody species comprising the hedgerow came into flower.

What Works in Conservation

What Works in Conservation assesses the research looking at whether interventions are beneficial or not. It is based on summarised evidence in synopses, on topics such as amphibians, bats, biodiversity in European farmland, and control of freshwater invasive species. More are available and in progress.
