Conservation Evidence: Evidence Data

Collected Evidence: Collected Evidence: Reduce adverse habitat alterations by excluding problematic terrestrial species Three studies from the USA and the UK found higher numbers of certain songbird species and a higher species richness in these groups when deer were excluded from forests. Intermediate canopy-nesting species in the USA and common nightingales Luscinia macrorhynchos in the UK were the species to benefit. A study from Hawaii found mixed effects of grazer exclusion, with some species showing population increases, some declines and other different long- and short-term trends.

Two studies from Australia and the Madeira archipelago, Portugal, found that seabird populations’ productivities increased following rabbit and house mouse Mus musculus eradications, with several other interventions used in the Australian study.

A study from Australia found lower mortality of Gould’s petrels Pterodroma leucoptera leucoptera following the removal of most of an island’s (native) bird-lime tree Pisonia umbellifera population, whilst a study from New Zealand found that Chatham Island oystercatchers Haematopus chathamensis could nest in preferable areas following invasive marram grass Ammophila arenaria control. A site comparison from the USA found lower densities of several birds in areas with (native) velvet mesquite Prosopis juliflora control.
