Supplementary materials: Monitoring recovery of overgrazed lichen communities on Hagemeister Island, southwestern Alaska

We estimate time to recovery with three competing growth curves which estimate grazeable biomass may be reached in 34-41 years. However, estimates of full recovery to climax biomass varied among the models, ranging from 71 to 400 years. In 2015, lichen communities were composed of various mixtures of at least 78 lichen taxa, and were dominated by Cladina stygia and other important reindeer forage species.

While reindeer overgrazing diminished forage quantity, it did not extirpate preferred forage taxa.
