"To have 400 survivors in your Wildlife Habitat project, you need to plant 43% 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 30% mortality rate is a realistic baseline.

Planning Breakdown

1

The Goal

Establish 400 mature stems/acre.

2

The Risk

At 30% mortality, you will lose 172 trees/acre.

3

The Solution

Order 572 seedlings. This "gross-up" ensures you hit targets despite natural loss.

Growth Profile

Classified as a Large evergreen conifer. While valuable for Structural lumber, it is notably susceptible to Root rot in wet soils during establishment.

Planter's Tip

"Ensure planting sites have excellent drainage to prevent fungal pathogens."
