River nutrient study update, July 2022

On 04 April 2022 I wrote River nutrient study. Recently I followed up about results. David Brown, with a Horizons Regional Council email address, replied: Sorry for the delay getting back to you, I had been trying to find out some more information. What I can report is that a large amount of data was collected for this project including:…

Dunnock and sparrow photos.

Sparrow and dunnock – which is which?

One of the emails I received from The NZ Garden Bird Survey team around the time of the 2022 Survey had handy info about Dunnocks and Sparrows: We’re not sure if this is happening with your whanāu, but we’ve noticed ours have definitely caught the birdwatching bug and they haven’t stopped looking for birds! Although there has been a bit…

Why are there two high tides per day?

An excellent 8 minute video by Dr Becky Smethurst, astrophysicist, explains how the Sun, Moon and Earth contribute to the tides: We all learn that the tides are caused by the Moon pulling on the Earth’s oceans. So how come there’s two high tides per day but we only have one Moon? Watch the video on YouTube: Why are there…

Stoat behind wire with bloodied body and mouth open revealing fangs.

Stoats are savage pests

Like everywhere else in the country we have our share of pests. One to watch out for is the stoat. Some folks have had success trapping them. When I’ve spotted stoats they’ve looked very handsome. Unfortunately they’re killers. I lost several quail to one and neighbours have lost chickens. Who knows what damage they’ve done to native birds! DoC say:…

June is gossamer month

Kezna Cameron let me know about something that happens in June — a Gossamer Event: where spiders coat our wet land in cobwebs This is when thousands of young spiderlings climb the stalks of plants to play out silk that is caught by the breeze.

NZ Garden Bird Survey 2022

25 June to 03 July 2022 is the week for the Garden Bird Survey. Why do we do the survey in winter? Aren’t birds less likely to be seen? And besides which, it’s freezing! Birds are active all year round, but in winter, when wild food is more scarce, they will tend to come into gardens to feed. This means…

Map showing streams.

The Strathnaver streams

An interesting thing about the Electra Outages site is their map of Waikawa Beach, which shows us the streams and drainage ditches in the area. There’s a stream that emerges from Lake Hurutini (bottom right corner of the map). It flows into the Strathnaver area, and then branches to go across Strathnaver Drive (by number 123) and into the Miratana…

Driftwood amongst the budding dunes.

Storms brought driftwood, large and small

The storms at the end of May 2022 ate away at the Manga Pirau Street beach entrance again, causing a 40 cm drop-off into driftwood. And they brought driftwood, large and small high onto the beach. It reached as far as the blue post at the beach end of the north track off Reay Mackay Grove, and into the area…

Kāpiti coastal hazard information

Kāpiti Coast District Council have just released (May 2022) a pile of Coastal science information. They say: We asked independent consultancy Jacobs New Zealand Limited to assess our district for coastal hazards, from Ōtaki in the north to Paekākāriki in the south. The assessment updates previous coastal hazard assessments of the Kāpiti Coast District shoreline. It identifies areas susceptible to…
