"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.

Silvics of Spruce

Picea spp.

Growth Profile

Classified as a Coniferous evergreen. While valuable for Wind protection and timber, it is notably susceptible to Spruce budworm during establishment.

Planter's Tip

"Inspect new growth tips annually for signs of defoliation."
