- 12. EASTERN REDCEDAR IN THE NIOBRARA RIVER VALLEY •Diminished ecosystem services Management Required •Decrease cedar densities •Decease cost of removal Clear Objectives •A small cedar market exists •Can we utilize harvestable materials to decrease costs? Opportunity to Learn Monitoring Reduces Uncertainty •Large economic and ecological cost to doing nothing Sustained Commitment modified from Williams et al. 2009
