To accomplish this, I used the standard methods found in Guide for Plant <br /> Appraisal. 9th edition (published in 2000 by the International Society of Arboriculture, <br /> Champaign IL). In addition, I referred to Species Classification and Group Assignment <br /> (1993), a publication of the Westem Chapter of the International Society of Arboriculture. <br /> These two documents outline the methods employed in tree appraisal. <br /> The value of landscape trees is based upon four factors: size, species, condition and location. <br /> Size is measured as trunk diameter, normally 54" above grade. The species factor considers <br /> the adaptability and appropriateness of the plant in the East Bay area. The Species <br /> Classification and Group Assignment lists recommended species ratings and evaluations. <br /> Condition reflects the health and structural integrity of the individual. as noted in the Tree <br /> Survey Form. Location considers the site, placement and contribution of the tree in its <br /> surrounding landscape. <br /> The appraised value of the trees recommended for preservation is $26.050 (Table 4). The <br /> appraised value of the Heritage trees recommended for removal is $24,350 (Table 4) <br />
