Thread: Any ex NZ forest service fellas here?

@Woody do you have knowledge on this topic?

It's a id tag on that tree.NZFS had permanent vegetation monitoring lines established in Native forests it managed.These lines are called transect lines and generally start in valley floors and run on a randomly generated compass bearing to the ridge/spur crest depending on the catchment topography.Each catchment had numerous transects in order to gain a statistically valid data base.Used for measuring many forest health perameters such as tree girth growth,mortality,animal density,Regen density,poison drops,etc etc .The (first)permalat marker in the valley floor has the transect id # and compass bearing for the bod to follow on,often with successive permalat markers @ 50 metre intervals on that bearing where each data point is taken.Measurements were taken every 5 years to gain long term trends for forest management.The ally id tag is tacked on @ brest height for the bod to measure & record what was called dbh _ diameter at brest height.These techniques still used in commercial exotic forests

In order to ensure data repeatability,some transects had the 50 mtr interval sites marked with permalat,and some didnt.Instead in the absence of intermediate markers the bod would strap on his waist a 'hipsometer' playing out a thin biodegradable cotton line with a distance recorder. So you would stop @ the 50 mtr interval once the counter got to 50,100,150 etc,etc . how many greying hunters remember encountering cotton lines during their stalks?They usually took a few months to break down.
