  1. This is solid information that will enable wise preventative measures against slipping to be taken. It must be noted and acted on in all areas of NZ as well as Marlborough.

    Following the severe flooding in Marlborough in July 2021 and August 2022, GNS Science mapped the distribution of landslides across the Marlborough Sounds and visited some properties to assess damage.
    Off the back of that research, a report prepared by Marlborough District Council soil scientist Matt Oliver said in both storms, the greatest number and density of landslides did not occur in the areas that received the highest rainfall.

    Nearly 4000 landslides were mapped after each of the storms.
    Data from 2021 showed 35.5 percent of landslides were triggered in harvested exotic forest, 28.7 percent in exotic plantation forest, 10.4 percent in broad-leaved indigenous hardwood, 6.1 percent in low-producing grassland and 6 percent in high producing exotic grassland.

    In 2022, 28.3 percent of landslides were triggered in high-producing exotic grassland, 18.6 percent in broad-leaved indigenous hardwood, and 13.1 percent in mānuka/kānuka. Exotic forest accounted for 8.9 percent and harvested forest for 5.9 percent of landslides.

    “The differences between impacts of the two storms illustrate how difficult it is to attribute slope failure to single causal factors,” the report said.
    “The storms occurred across different locations, at differing intensities, total rainfall, and timing.
    “The differing locations led to differences in local geology and land use. However, what seems clear from these data is that landslide density cannot be solely attributed to rainfall alone.”

    Speaking to councillors at an Environment and Planning committee meeting this month Oliver said the “problem” was forestry and human interaction with the land.
    “Let’s just get it out there,” he said.

    “Harvest forest and exotic forest makes up around about 18 percent of the land cover (in 2021), yet it contributed something in the order of 65 percent of the landslides.
    “The rain didn’t fall evenly. It fell everywhere, it fell most heavily on the indigenous forest, and it fell most heavily on the highest slopes, yet those are under-represented.”

  2. NATS – privatised away responsibility by privatising prisons with Serco.
    LABOUR – bureaucratised away responsibility by folding the Childrens Commission into the ERO, and folding the Elder Health Commission into the HDC.
    ME – I would have a referendum in October, putting the question whether to increase the top tax rate by 1%, in exchange for taking GST off fresh fruit and veg, and giving everyone a free dental appointment every 2 years.
