Tier 1 tree tag. Permanent monitoring of a 20x20 site. You get to site, set up tapes to mark the 20x20 based on the orientation of the red permolat being centre of plot, then split 20x20 into 1m2 subplots. Then measure dbh of all trees with a tag, multileaders are over a certain dbh hence they get tagged as well. Also inventory species and seedling counts over the whole plot.
These plots are on a 5 yr rotation, and most were set up in the early 2000s when DoC were looking at measuring stored carbon of the conservation estate. In theory those plots should be every 7km.
