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.
