RAINFOR methodologies

Dear All,

Measuring tree heights. About a week ago a CTFS paper came out about measuring tree heights by Markku Larjavaara and Helene Muller-Landau (see,%20a%20quantitative%20comparison%20of%20two.pdf ).

Apologies if other people have seen this before me, but I think it is important to stress that in RAINFOR we measure STEMLENGTH for our tree heights (see section 1.5 of the GEM manual) but in CTFS they measure vertical height to crown top. For leaning trees these are not the same so please don't use the methods proposed in that paper in RAINFOR-GEM plots (neither their tangent method nor their sine method).
