Garden bird survey: 29 June – 7 July 2019

The 2019 Garden Bird Survey needs you! It’s on from 29 June to 7 July 2019, and takes only 1 hour of your time.

What to do:

  1. Choose just ONE day that suits you
  2. Find a comfy seat (either inside or outside).
  3. Look and listen for birds for ONE hour.
  4. For each species record the HIGHEST number seen at one time.
  5. Print a tally sheet (optional but recommended): recording made easier!
  6. Use the online form to enter your data

OpenTopography map shows erosion and accretion

A community member drew my attention to the OpenTopography project and the map that can be created showing erosion and accretion over part of Waikawa Beach between 2013 and 2015.

Topography measures the height of natural features, such as the ground. If you compare how high the ground is between two different years you can detect how much that height has changed.

To generate the map for yourself you will need to watch the very clear and helpful 10-minute explanatory video.

The maps below are what I produced after watching the tutorial.

Report from the Public Meeting on erosion

On Saturday 08 June 2019 Ramon Strong from Horizons Regional Council informed around 70 people about the findings of the Tonkin and Taylor Report on our river mouth and erosion.

Horowhenua District Council Mayor Michael Feyen, John Foxall and Hinewai Pouwhare-Anderson of Horizons, Councillor Lindsay Burnell of Horizons also attended and there were some 30 apologies.

Groyne changes at the river mouth, June 2019

The diggers did great work over the last two days and it’s good to see the rock groyne now lines up with the river and has been bolstered. The rocks have been laid fairly broad and low rather than narrower and higher.

With any luck this change will reduce the erosion caused by the river in times of flood, storm and high-tide by helping it move towards the sea rather than doubling back to the dunes.

The digger driver also shaped the vehicle entrance before leaving. It should at the moment keep any driver happy for ease of use.

The groyne now follows the upstream course of the river and bank.

Diggers relocate the high-angle groyne

As promised, two diggers and a dump truck turned up first thing on Tuesday 11 June 2019 to dig out the high-angle rock groyne and use the rocks to build up the 1991 groyne.

The photos below show the diggers at work and fluorescent paint marking a strip where presumably the rocks will end up.

Horizons State of Environment Report 2019

Horizons Regional Council have recently released their State of Environment Report 2019 and it’s an interesting read. It’s clearly written and well-designed which makes it easy to find the information you’re interested in. Waikawa Beach is specifically mentioned a couple of times.
