The dominant lifeform in each stratum. The lifeform codes are taken from the lifeform table as above. Therefore life-form 1 is trees> 8 metres moving down to a life-form of 15 for vines. Upper stratum life-form. Middle stratum life-form Ground stratum life-form This is the total vegetative cover in the sample site that occurs in each stratum. For the upper and mid stratum it is generally a %crown cover while for the ground layer it is generally a straight %cover. This box (with heights) is a 'summary' of the structure of the vegetation at any site. (Variables 21-50 are an expansion on this table. ) Upper stratum %cover Middle stratum %cover Ground stratum %cover The average height of each stratum in metres. Upper stratum height. Middle stratum height. Ground stratum height. Wedge factor used when measuring basal area. Variables used when analysing data Decimal degrees longitude Decimal degrees latitude The community number resulting from data analysis Number of species at the site 2.2 SPECIES ABUNDANCE MEASURES There are three abundance measures for each species based on structure: 1 BA/CO UPPER The basal area for each species in the upper stratum determined using a basal wedge. Generally this is the dominant stratum. In the case of grasslands the abundance measures were determined as percentage cover of the plot and placed in the lower stratum. Were the plot Is a grassland and/or the dominant stratum is the lower stratum 2 COV MID The percentage cover of the plot by mid stratum species. This is a percentage crown cover. 3 COV LOW The percentage cover of the plot by ground stratum species. 4
