Methods
BioTIME managers note: for v2, only control plots were retained.Vegetation biomass is estimated using a 0.25m2 point frame with 20 pin hits per frame. All encounters with the lowered pin are recorded until substrate is hit.
Point frame using ITEX protocol.
[VASC 2004]: Point frame 2 (50x50cm, 270 holes, 30 holes/row, 9 rows, needle diameter<0.5mm). Frame 2 calibrated with frame 1 so unitsin databasearethe same.2. The Abundance units:Point frame hits, [VASC]all hits, except Empetrum/Andromeda: one hit per branch; [Crypt]firsthit
