Figure C-1. Shrub survival by inoculation treatment. <br />100 <br />80 <br />m <br />.~ <br />60 <br />w 40 <br />20 <br />Overall Serviceberry <br />^ Control <br /> Field Inoculation <br /> Nursery Inoculation <br />I <br />Height was not affected by treatment (p<0.05). Height data was confounded by browse which <br />occurred on the site. Browse rates were calculated and compazed to determine whether any <br />treatment was preferentially browsed. Browse damage occurred on 51% to 71% of plants but <br />was not statistically different between treatments. Browse damage at these rates is expected to <br />affect survival in the future. <br />Vigor was also evaluated as a factor. The percentage of plants rated as vigorous during field <br />' monitoring were compazed across treatments. No statistically significant differences occurred in <br />the vigor of the plants. All surviving plants were similaz in height, crown, and general <br />_ appearance of health. <br />A total of six plants per replicate (72 plants total) were destructively sampled. Roots were <br />measured and mycorrhizal colonization was checked to determine the effectiveness of <br />inoculation methods afrer approximately one yeaz under field conditions. Ironically, all plants <br />were colonized with mycorrhizal fungi regardless of treatment. The control, field inoculation, <br />and nursery inoculation methods yielded 59%, 63%, and 54% colonization respectively. It is <br />known that nursery inoculated plants were colonized prior to outplanting while control and field <br />inoculated plants were colonized during the growth period in the field. Prior colonization may <br />account for the higher survival rates of the nursery inoculated treatment. <br />20 <br />
