How does woody succession affect population densities of passerine birds in New Zealand drylands?

  title={How does woody succession affect population densities of passerine birds in New Zealand drylands?},
  author={Deborah J. Wilson and Grant L. Norbury and Susan Walker},
The density of shrubs is increasing in many dry grassland ecosystems worldwide. In the dry interior of the South Island, New Zealand, secondary succession generates novel woody communities, as shrubs colonise anthropogenic grasslands where fire frequency has decreased. The avifauna of this dry region is also novel, with many indigenous birds extinct, extirpated or uncommon, and exotic species predominant. We studied how succession from grassland to shrubland habitats affects the abundance of… CONTINUE READING
