'Wholesale slaughter' of Auckland's trees

It blames the ease at which non-notified consents are granted and government removal of tree protection rules.

One third of Auckland's trees have been cut down in the past five years, the Tree Council reveals.

"Since the government removed general tree protection rules in 2012, there's been wholesale slaughter across the city," secretary Mels Barton says.

"Because it's very difficult for local councils to protect trees now unless they're individually scheduled in a plan or they're in some kind of special area."

Barton says it's horrifying that the city's lost approximately one third of its trees in the past five years.

"Based on the reports we've been getting from arborists, from our members and from the general public across the city ... and from local government information act requests that we've made about the number of consents that have been issued for protected trees, we can see that there's absolutely massive amounts of tree removal going on," she says.

"And we estimate that that means we've lost approximately one third of Auckland's tree cover."

Barton showed NZH Focus a stack of approved consents by Auckland Council in 2013 and 2014. Many of those did not relate to just one tree, but several.

She says the rate of loss is accelerating.

"And we're not even seeing the impact of the Unitary Plan yet."

Barton expects more trees to be lost as intensification of the city continues.

"One of the main problems is the non-notified consent applications.

"So basically even if the trees could be accommodated in the development like around the outside or maybe they're going to be part of the reserve, as with the Snells beach tree, those trees still aren't being kept by the council."

She says Auckland Council is currently analysing remote sensing data on the city's tree loss.

"What we're anticipating is that when they get those results, they will back up what we've been seeing on the ground."

The Auckland Council says because of the 2012 changes to the Resource Management Act, it doesn't have a record of the number of now-unprotected trees chopped down.

And it did not answer NZH Focus' questions on exactly how many consents have been issued to cut down trees that are still protected under the Act.
