In the late 1970s, trials were established in the northern interior of British Columbia to investigate alternative regeneration methods and the suitability of different forms of seedling stock on brush-prone sites. This report summarizes the 20 year results of four of the planting trials1 in the Prince George Forest Region, where the effects of stock type and size on tree survival and growth we...

Most afforestation hardwood plantations in the Central Hardwood Forest Region, USA, are established with bareroot seedlings planted in late winter or early spring. This brief planting season is preferred for several logistical and physiological reasons, yet interest in fall planting has increased as a means to extend the planting season. We evaluated effects of a wide range of planting dates on...

Regenerating longleaf pine by artificial means is an essential component of restoring the ecosystem across most of its range because there are limited acres of longleaf stands remaining. Establishing longleaf pine is an early step in the ecosystem restoration process. An overview discussion of artificial regeneration techniques and related issues are presented this paper. Other papers follow in...

While fungicides may be a major mechanism for control of avocado root rot, integrated management requires several other non-fungicidal approaches which are used together to maximize root rot control. Non-fungicidal methods of control include planting clean avocado nursery stock, selecting low hazard sites, planting on mounds in more hazardous sites, preventing the introduction of P. cinnamomi, ...

Site preparation plays a vital role in British Columbia’s regeneration program (Figure 1). Historically, prescribed fire has been the tool most commonly used to satisfy the needs of both hazard abatement and site preparation. Recently, the use of fire has decreased relative to other options (Figure 2), due to the increased cost of burning, the increased public concern in areas sensitive to smok...

The quality of planting material is one of the key factors that determine the success of tree farming and reforestation activities. In the Philippines, low quality seedlings are commonly used in smallholder plantings for reasons such as the limited supply of high quality seedlings and smallholders’ lack of awareness of the benefits of using high quality planting stock. The ACIAR-funded seedling...

The grass stage is an inherent and distinctive developmental trait of longleaf pine (Pinus palustris), in which height growth in the first few years after germination is suppressed. In operational forestry practice the grass stage extends for two to several years and often plays a role in planting failures and decisions to plant alternative species. Interspecies hybrids involving loblolly (P. t...

Open lichen woodlands (LWs) are degraded stands that lack the ability to regenerate naturally due to a succession of natural and/or anthropogenic disturbances. As they represent both interesting forest restoration and carbon sequestration opportunities, we tested disc scarification and planting of two sizes of containerized black spruce (Picea mariana Mill. (BSP)) seedlings for their afforestat...
