Ash Sapling Mortality Calculator for Wetland Restoration
Targeting Hydrological function recovery? Calculate the exact Ash order volume needed to overcome Water level fluctuation.
Project Goals
Trees to Order
Buy 216 extra to account for loss.
"To have 400 survivors in your Wetland Restoration project, you need to plant 54% more trees."
The Challenge
Every restoration project faces unique pressures. In the context of Wetland Restoration, the primary failure point is often Water level fluctuation.
Species selected must be capable of tolerating both periodic inundation and anaerobic soil conditions. To achieve Hydrological function recovery, project managers cannot rely on "best-case" survival rates. Budgeting for a 35% mortality rate is a realistic baseline.
Planning Breakdown
The Goal
Establish 400 mature stems/acre.
The Risk
At 35% mortality, you will lose 216 trees/acre.
The Solution
Order 616 seedlings. This "gross-up" ensures you hit targets despite natural loss.
Silvics of Ash
Fraxinus spp.Growth Profile
Classified as a Deciduous hardwood. While valuable for Tool handle timber, it is notably susceptible to Emerald Ash Borer during establishment.
Planter's Tip
"preventative treatment is required in areas with known borer activity."
