↵zNeed index: average of responses where 1 = increasing need, 0 = no change, and —1 = decreasing need over the next five years.
↵yWeighted index: (Need Index/2) * (Total Respondents)2 was used to order the results. The weighted index gives greater weight to those trees where more respondents answered.
