Forest Call this week looks at how the industry is dealing with the issue of forest debris flows from the massive storms at Tolaga Bay and Takaka earlier this year.

For a comprehensive growers levy-funded report on tree species for steep slopes see Trees for steep slopes.

There may be opportunities to diversify into specialty timbers planted on red zone slopes, especially where managed as a permanent canopy.

  1. I don't agree with Andy Karulus that the effects of windthrow on economic value make it imperative to harvest early on separation point granite. No operation should have any issues with extracting windthrown areas given the clear need for continued harvesting and replanting over time, with some stands growing for up to 35 years, i.e. manage the area that is clearfelled at any one time over the whole catchment. Early harvesting is way more risky in terms of debris flows and erosion (window of vulnerability increases), is he talking about economic risk without considering environmental consequence?
  2. I don't agree with John Webster that residue "has no value" and therefore all residue is "unmerchantable'. It's time to get over that notion and supply biomass into alternative markets such as activated charcoal, animal bedding and biofuel. This is a no-brainer and there should be an industry standard that specifies maximum residue levels left on or adjacent to landings, even if the land were relatively "stable".
  3. I think that David Rhodes should have explained why the "core of the forest" should be radiata pine beyond "cos you still need to have that rotation and keeping guys employed etc". The rationale needs to be clearer given that alternative species potentially produce greater returns and better environmental outcomes.
