Sun Creek – 08 Shrubs and Herbs

Final Report, Forest Restoration of Sun Creek, Crater Lake National Park

 Research Summary

Shrubs and Herbs

Logged areas had more shrub cover before the prescribed fire than unlogged areas. Most of the shrub cover in ponderosa pine areas was snowbrush with some chinquapin. The sugar pine area had more chinquapin and some pinemat manzanita. Fire reduced shrub cover on all plots; a sample shrub/fuel map before and after fire is shown in Figure 6. The ponderosa unlogged plot, which had the slowest moving fire, resulted in the least sprouting the year following the fire. A new shrub genera, Ribes (gooseberry), appeared on the plot after the fire. Seeds dormant in the soil were stimulated to germinate after the fire.
