The file describes woody vegetation in a portion of Fiby urskog, Sweden including both mire and terrestrial vegetation to facilitate interpretation of a pollen analysis. 
The girth of all trees were measured at breast height (170 cm) in a circle with a radius of 30 m (origo = sampling point). The circle was divided into 12 sectors (30 degrees) which were individually investigated. Species of each tree was determined as well as its belonging to mire (m) or terrestrial (t) habitat.

Column 1, rows 2 - 454 displays tree number
Column 2, rows 2 - 454 sector number (1 - 12)
Column 3, rows 2 - 454 species
Column 4, rows 2 - 454 number of stems/tree individual
Column 5, rows 2 - 454 girth in cm
Column 6, rows 2 - 454 basal area in cm2 
Rows 456 - 458 display sums of tree basal area per habitat and total basal area expressed as m2.
