Native Frogs

Archey's frog

Archey's frogs are small (less than 50 millimetres long) native frogs that are at sparse or nationally critical levels. Archey’s frogs lack webbing between the toes whereas Hochstetter’s frogs have partial webbing between the toes.  The species has been found in the Whangapoua Forest on the Coromandel peninsula.

 

Hochstetter’s frog

Ernslaw One have funded a project which aims to assess the medium and long term impact of production forestry on Hochstetter’s frog populations in the Coromandel Peninsula Whangapoua Forest  in order to assist forest managers with how best to manage production forest to maintain Hochstetter’s frog habitat.

Analysis of the data is currently underway to assess the effects of production forestry on Hochstetter’s frog populations in Whangapoua Forest by comparing Hochstetter’s frog occupancy in streams within production forest recently harvested, production forest harvested 25-35 years previously, and native forest.  This will assist in classifying the importance of upper catchment head-water streams as breeding habitat for Hochstetter’s frog by comparing Hochstetter’s frog occupancy in streams within sub-catchment areas less than and greater than 20 hectares.

Ernslaw One is helping to protect both frog populations by:

  • where practical fencing off some areas to keep stock out
  • carrying out surveys prior to harvest to identify if frogs are present
  • changing harvesting plans so as to avoid areas with frogs
