The practice of mulching forested sites for industrial activities during winter operations is a useful construction practice as it minimizes soil disturbance by protecting the forest floor. However, wood mulch can be counterproductive during the revegetation phase as this mulch exhibits alternating periods of excess moisture or extreme dryness, both situations hindering seed-based plant re-establishment. Applying site preparation techniques that act to displace the mulch and expose the soil surface can enhance substrate conditions for establishment and growth of desirable plant species.
