Plant wild bird seed or cover mixture
A replicated, controlled, before-and-after study from 1998-2003 (three years habitat manipulation and three years monitoring) in four cereal farms (12-20 km2) in the Beauce, Grande Beauce and Champagne Berrichonne regions, France (Bro et al. 2004) found that grey partridge populations were unaffected by cover strips. Neither breeding density nor the reproductive success of breeding pairs increased in managed compared to control areas. The survival rate was significantly lower in managed areas for all winters except for one winter in one site. Observations suggested that cover strips attracted predators, such as foxes Vulpes vulpes and hen harriers Circus cyaneus, causing the managed land to become ‘ecological traps’. Cover strips (500-1,000 ha/farm) were either set-asides or, typically, a maize-sorghum mixture.

Neither breeding density nor the reproductive success of breeding pairs increased in managed compared to control areas. The survival rate was significantly lower in managed areas for all winters except for one winter in one site. Observations suggested that cover strips attracted predators, such as foxes Vulpes vulpes and hen harriers Circus cyaneus, causing the managed land to become ‘ecological traps’. Cover strips (500-1,000 ha/farm) were either set-asides or, typically, a maize-sorghum mixture. Partridges were surveyed in March and mid-December to early-January to assess overwinter mortality, and in August to assess reproductive success.
