Control scrub on farmland

How is the evidence assessed?

Study locations

Key messages

A replicated study from the UK found a negative relationship between the number of young grey partridge Perdix perdix per adult and a combined intervention of scrub control, rough grazing and the restoration of various semi-natural habitats.

 

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 site comparison study on 1,031 agricultural sites across England in 2004-8 (Ewald et al. 2010) investigated the impact of scrub control on grey partridge Perdix perdix. However, the study does not distinguish between the impacts of scrub control, rough grazing and the restoration of various semi-natural habitats. There was a negative relationship between the combined intervention and the ratio of young to old partridges in 2008. This study investigated several other interventions, discussed in the relevant sections.
