Phase 2: Regenerating native woodland Phase 2 – regenerating native woodland

Does the current management allow the regeneration of native trees that are appropriate for the objectives at the site?

Continue with current management

Consider all factors that are likely to limit the potential for regeneration and carry out relevant treatment

Excessive herbivore impacts

Competitive vegetation

• Too few parent trees • Too much seed predation • Young seedlings failing to establish • Inappropriate species

Manage herbivore populations, exclude animals from the site or protect trees

Use appropriate methods to manage vegetation

Plant trees to restock or enrich the site with desirable species that are failing to establish

Light

Too little

Too much

Wait for canopy cover to develop and carry out management to encourage regeneration

Is the stand sufficiently stable and accessible to allow regular thinning, and does the plantation comprise non-invasive species?

Are you prepared to wait for a long time beyond economic maturity?

Clearfell following Phase 1

Thin to marginal intensity well beyond normal rotation

Carry out heavy thinning and/or group felling around mature trees and remnant patches of desirable ground flora (removing ~40–50% of the basal area of plantation species). The remainder of the plantation should be removed after assessing the information gathered during monitoring.

Monitor the effectiveness of management

Note that any operations to regenerate a native woodland must not have an adverse effect on the ancient woodland remnants.
