Vegetation classification was tested for several abundance measures: stem density per ha, basal area per ha and presence/absence (P/A) of the tree species.
Measured stem dry weight increased from 21 kg·tree−1 in 6 yr.
A semi-automated software interface was developed to measure stem diameter due to the strict sampling strategy and the complexity of high-density crop canopy.
We measured height and stem density under two distinct conditions: outside without controlled vernalization and in growth chambers with staggered vernalization to synchronize flowering time.
mortality or a coppicing response (i.e. the production of new stems after the terminal part of the main stem has been removed [44]), changes in both the density of individual trees (which measures mortality, but also reflects recruitment) and stem density (which measures the coppicing response or mortality of vertical stems) were investigated.

We measured variation in tree size, stem density, basal area, and seedling recruitment among 90 sites that encompassed a wide range of climates and landscape settings across Australia.
Plant height and stem density were measured weekly in response to tidal treatment.
We sampled bird communities with point counts and measured visual obstruction, pine tree height, woody stem density, and vegetation structure and coverage by growth form (e.g., forb, fern, grass, legume, pine, sedge and rush, woody non-pine, vine).
Then, focusing on still visible and homogeneous segments of tiller barriers only (49 segments), the basal diameter, basal stem density and basal shoot branching of the tillers, as well as the sediment deposit heights were measured in spring 2010.
