"To have 600 survivors in your Timber Plantation project, you need to plant 67% more trees."

The Challenge

Every restoration project faces unique pressures. In the context of Timber Plantation, the primary failure point is often Monoculture pest vulnerability.

Thinning regimes are crucial to maintain stand health and maximize growth rates. To achieve Commercial wood yield, project managers cannot rely on "best-case" survival rates. Budgeting for a 40% mortality rate is a realistic baseline.

Planning Breakdown

1

The Goal

Establish 600 mature stems/acre.

2

The Risk

At 40% mortality, you will lose 400 trees/acre.

3

The Solution

Order 1000 seedlings. This "gross-up" ensures you hit targets despite natural loss.

Silvics of Hemlock

Tsuga spp.

Growth Profile

Classified as a Shade tolerant conifer. While valuable for Winter wildlife cover, it is notably susceptible to Woolly adelgid during establishment.

Planter's Tip

"Treat aggressively if white woolly masses appear on needle undersides."
