"To have 400 survivors in your Wildlife Habitat project, you need to plant 67% more trees."

The Challenge

Every restoration project faces unique pressures. In the context of Wildlife Habitat, the primary failure point is often Predation of seedlings.

Structural diversity in planting arrangements attracts a wider range of animal species. To achieve Biodiversity support, 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 400 mature stems/acre.

2

The Risk

At 40% mortality, you will lose 267 trees/acre.

3

The Solution

Order 667 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."
