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

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.
