The importance of relative dependency of plants on root-                symbiotic (mycorrhizal) fungi may be critical to plant succession               on new soils, but this area of ecology has received little                      attention.  Glaciers of the North Cascade Mountains of Washington               suit this purpose.  In receding, they deposit rubble initially                  devoid of symbiotic fungi, which increase in time of exposure                   with distance from the glacier terminus.  Plants that colonize                  these glacier forefronts over time will be compared with the same               species in adjacent, undisturbed communities for mycorrhiza                     formation.  The three major groups are plants that (1) survive                  without the symbiotic fungi, (2) depend on mycorrhizal fungi                    dispersed by air, and (3) depend on mycorrhizal fungi dispersed                 with moving soil.  Plants in group 1 are predicted to be first                  colonizers, followed in turn by groups 2 and 3.  Field sampling                 and greenhouse and growth chamber inoculation experiments will                  test the hypothesis.  If true, it will explain why only a few of                the many seed-producing plants adjacent to glaciers are initial                 colonizers.  This contribution to ecological theory has many                    applications in interpreting successional phenomena and in                      rehabilitating disturbed or degraded ecosystems.
