The bounty hunters who fought for the eradication of a species
With only 3000 to 7000 kea remaining, and numbers declining every year, reporter Charlie O’Mannin looks back to the days when a government bounty of up to $75 a beak led to the destruction of 150,000 of the birds over a hundred years of slaughter.
Old man’s beard still hasn’t gone | Te Papa’s Blog
Wellington recently competed in the iNaturalist City Nature Challenge. During the four days of the Challenge people recorded as many observations and species as possible.

Chicago releases 1,000 feral cats to end reputation as rat capital of America
Chicago has released more than 1,000 feral cats onto the streets — hoping to end its long-running ranking as the rat capital of the US.

Zealandia reservoir to be drained to remove a tonne of pesky perch –STUFF March 2021
The lower reservoir at Zealandia is being drained this month to remove around a tonne of unwanted fish, which are eating native species and throwing the ecosystem off balance. Perch were introduced to Roto Kawau, the lower part of an existing man-made reservoir, more 140 years ago, by people wanting to create fishing opportunities.

New Zealand's wallaby problem tough to tackle, fears hunters spreading them
New Zealand's wallaby problem could become a full-blown plague unless efforts to control them are ramped up and 'shortsighted' hunters start playing by the rules. Forest and Bird says the pests could spread to cover a third of the country unless the Government steps in to fund a beefed-up control programme. Central North Island regional manager Rebecca Stirnemann said wallabies were like giant rabbits, eating their way through native bush,
Biocontrol – slow and steady wins the race
Paul Peterson and colleagues from Manaaki Whenua, Massey University and the Open Polytechnic recently published the findings from a long-term, carefully controlled study, partly funded by SSIF, comparing herbicide use with biocontrol methods for the control of invasive heather in and near Tongariro National Park. Their work was named ‘Paper of the Month’ for June 2020 by the Journal of Applied Ecology.
