Restoration ◆

Ice storm ‘98 — one of the greatest Canadian natural disasters Impact on some plantations was devastating Particularly 15 cm and greater in red pine ◆ Most plantations had some damage 10­100% ◆

6­4

Looking at conifers — focus on red pine, white pine, and jack pine with a brief look at white spruce, and larch

Restoration ◆

Before doing a lot of physical work, need to review: ◆ ◆ ◆

7­5

extent of damage other problems why is the plantation there

Assessment Records ◆

Need to know ◆ ◆ ◆ ◆ ◆

7­6

Why a plantation? What is growing? What is wrong and how much? What work done? The dynamics

Caring for Your Land Series of Workshops


Conifer Plantation Management

Assessment Records ◆

Have to decide on:

Your Goals ◆ Potential products ◆ An Action plan to address concerns ◆

7­7

Conifer Plantation Management

Points to Remember ◆ ◆ ◆ ◆

7­8

Originally planted 2,000+ trees/hectare Final crop will be 200­300 trees/hectare Identify potential crop trees — enough? Will pruning improve potential for sawlogs?

Points to Remember — 2 ◆

What other factors need to be considered? convert now ◆ Replant with conifers ◆

7­9

What were the silvicultural objectives for the plantation? What do you want?

Species and their Roles ◆

Red pine “nurse crop” to provide a suitable micro site for the development of a hardwood understory ◆ provide an excellent range of forest products ◆ good return on investment ◆ usually not part of natural forest on site after the final harvest ◆

White pine ◆

7­10

“nurse crop” as above but will be part of future natural forest on site

Caring for Your Land Series of Workshops


Conifer Plantation Management

Species and their Roles ◆

Jack pine ◆ ◆ ◆ ◆ ◆

7­11

“nurse crop” for those difficult sites able to capture shallow dry sites provide site protection may provide suitable environment for invasion of hardwoods little opportunity for forest products

Red Pine — Older Plantations ◆

Damage can be total — domino effect Partial loss needs to be designed into thinning

Start conversion process sooner

Red Pine — Younger Plantations ◆ ◆

7­13

Caring for Your Land Series of Workshops

Prune for leader to make 2 sawlogs Clip all branches except one in top whorl Design thinning to remove trees with broken tops


Conifer Plantation Management

White Pine ◆

◆ ◆ ◆ ◆

7­14

Caring for Your Land Series of Workshops

Variable damage in plantations up to 15 metres Compounded by heavy weevil damage Enough crop trees? Is pruning an option? Patience


Conifer Plantation Management

Jack Pine ◆ ◆

7­15

Nurse crop for hardwood invasion On older sites hardwoods usually present Damage on jack pine will actually release hardwoods Clean trails and reduce fire hazard without injuring hardwoods

Tamarack/Larch clip ◆

◆ ◆

7­16

In many cases top 1­2 metres broken off tress 10­15 metres high Original planting survival sometimes low May need clipping Broken stub could be trimmed to allow tree to “heal” sooner

White Spruce ◆ ◆ ◆

7­17

Little to no damage Where leaders broken, clip all but one lateral to ensure only one leader Consider early thinning

Conifer Plantation Management

Why Prune Broken Tops? ◆ ◆ ◆

7­18

Caring for Your Land Series of Workshops

Tree has one leader Clean stub — healing Increase log length


Conifer Plantation Management

How to Prune ◆

7­20

Caring for Your Land Series of Workshops

Pruning cuts should be made just outside the branch collar Large branches should be removed by 3 step method Cuts in leader should be at 45 degrees or along a branch bark ridge


Conifer Plantation Management

When to Prune ◆

Prune live branches in dormant season Late winter or early spring before leaf formation ◆ Maximizes growth and wound closure ◆

7­21

Remove diseased or dead branches any time

Caring for Your Land Series of Workshops

Pruning Equipment ◆ ◆ ◆

7­22

Use proper tools Clean and sharpen Comes with extension poles for pruning to 17 feet

Assess the whole health of trees and plantation Review goals Develop action plan Review annually

◆ ◆ ◆ ◆

7­23

Caring for Your Land Series of Workshops

Do any corrective work in dormant season Concentrate Work on crop trees Cut slash close to ground Use proper tools
