30ConservationWhile <strong>the</strong> hunt for Fox and o<strong>the</strong>r predatorymammals hasn’t improved <strong>the</strong> reproductionrate of <strong>the</strong> bustards, <strong>the</strong> fox-proof fences in<strong>the</strong> conservation areas have demonstrated<strong>the</strong>ir worth. With <strong>the</strong>ir sense for safety <strong>the</strong>free ranging adult hens now seek out <strong>the</strong>sefenced-in areas for <strong>the</strong>ir broods. Above allin <strong>the</strong> Havelländisches Luch <strong>the</strong>y prefer <strong>the</strong>“pens” to <strong>the</strong> surro<strong>und</strong>ing landscape. Up to15 hens brood here at once on an area of 18hectares and bear up to 11 fledged youngper year – significantly more than outside <strong>the</strong>protection fences. One can hope that this aidmeasure will only be temporarily necessaryand that <strong>the</strong> bustards will one day be able tosuccessfully brood in <strong>the</strong> wild.20181614121086420Number of fledged youngper year1990199119921993199419951996199719981999200020012002200320042005200620072008200920102011500450400350300250200150100500gef<strong>und</strong>eneBrutplätzeOpen landProtection fencegeschlüpfteKükenflügge KükenProtecting <strong>the</strong> birds from gro<strong>und</strong> predators in <strong>the</strong> fenced-in areas has led toan increasing reproduction rate in <strong>the</strong> German Great Bustard project.Comparison of <strong>the</strong> reproduction rate in <strong>the</strong> wild and in <strong>the</strong>fenced-in areas in <strong>the</strong> Havelländisches Luch 1990-2011.
