HomeMy WebLinkAbout20081317 Ver 1_Table 6 2014 5th Annual Stream Buffer Total Survival_20160314Table 6. Survival of trees and shrubs by species planted in 19 0.017 -acre plots in 0 -50 -foot riparian buffer at Hell Swamp from baseline (summer
2010) to fall 2014. Species with no values in any columns were among the planted stems but not represented in any buffer plots.
'The number tagged at baseline has been adjusted to reflect the proper identification of species and more planted stems found in later fall
sampling events.
2Survival was considered unsure if the stem appeared dead (brittle, no green, broken, etc.) at the current sampling event and dead if at both the
current and last sampling events the stem was not unquestionably alive.
3Total includes alive + unsure.
4Percent survival was calculated as: (Fall/Baseline tagged) X 100.
