“…Well-established conifer advance regeneration may survive and grow well without weeding after partial cutting, but this approach has not been tested in Ontario BMW stands. Alternative methods such as partial cutting are needed for maintaining conifers on competitive sites because herbicides may reduce plant diversity (Newmaster et al, 1999) and the public opposes herbicide use in forestry (Lautenschlager et al, 1998).…”

“…Despite the proper regeneration and soil preparation, plantation still often needs a release treatment. Forest vegetation control with herbicides is a cost-effective option (Nilsson and Örlander 1999, Lautenschlager et al 1998, Jobidon 2000, Hytönen and Jylhä 2008, Boateng 2009). However, the use of herbicides in forestry has strong public opposition (Lautenschlager et al 1998), and for example in Finland, forest certification restricts the use of chemicals, especially in hardwood control (PEFC FI 1003:2009, why alternative methods are rather used.…”

Effective management of Norway spruce (Picea abies (L.) Karst.) plantations requires detailed information on stand development, which is costly to measure. However, estimating the need for early stand management from site attributes that persists stabile after ones measured, may provide an inexpensive alternative. This study compared hardwood competition in spruce plantations of varying ages and tested the usability of this information in estimating the need for early cleaning.The data included 197 spruce plantations (4-7 years old) inventoried in southern Finland in 2007. The level (Low, Substantial, High) of need for early cleaning was subjectively determined by contrasting location and size of competing hardwoods to a conifer crop tree. Then the stage of the need for early cleaning was modelled according to site and stand attributes.Nearly 60% of the conifer crop trees in the plantations were subjectively judged to require early cleaning (Substantial 37.2%, High 21.2%), but only 10 per cent of the evaluated area was cleaned. Need for cleaning was intense on peatlands or damp soils, whereas it was mild on unprepared soils or cleaned sites. Traditional site characteristics used in forest management planning can be useful for recognising the peripheral cases, where need for cleaning is probably high or low. However, on a typical mineral soil plantation (uncleaned, soil prepared) the model indicates the differences in the need for early cleaning weakly.The need for early cleaning was already high in 4-year-old plantations, why stand age did not have significant effect on development of the need. Thus, the timing of an operation can not be predicted with the model. Nonetheless, early cleaning very likely opens growth space of crop trees in a 4-7-year-old spruce plantation. Therefore, from an aspect of crop growth, an uncleaned Norway spruce plantation in this age group is quite consistently worth cleaning.

“…8b). Of papers classified as documenting environmental effects of forest vegetation management practices in Canada since 1990, almost all were studies investigating the environmental fate and effects of chemical herbicides [29,65,69,76,77,79] and several were generated by a major multidisciplinary study conducted in northwestern Ontario [45,66,79]. Very few studies were conducted on the potential environmental effects of other vegetation management techniques.…”

“…While some long-term study sites have been established (e.g. Carnation Creek, Cowichan Lake and MASS study sites in British Columbia [12], Fallingsnow Site in Ontario [45]), the commitment and funding support to these is often tenuous. Moreover, although long-term studies are recognized as having substantial potential for effects on forest management policy (BCMOF 2001), there has been no coordinated strategic planning at the national level to ensure that appropriate sites, representative of the major forest regions in Canada, are selected for comparative, long-term, vegetation management studies.…”

-Research and practice in Canadian forest vegetation management was reviewed for the period 1990 to present. Results indicate continued evolution toward a more integrated and ecologically sound program with appropriate focus on key competitors and crop species. Increasing collaboration between academia, government and industry has resulted in > 666 new scientific publications, substantially augmenting the existing knowledge base. The development of (Chondrostereum purpureum) as the first biocontrol agent in Canadian forest vegetation management and the use of nutrient-loaded seedlings to enhance establishment success are considered key research highlights. Recent trends in operational practice include a move toward more intensive management on higher quality sites and adoption of innovative approaches (e.g. nutrient loaded seedlings, larger planting stock) and advanced technologies (e.g. electronic guidance in aerial herbicide applications). The lack of long-term growth response data and economic analyses demonstrating positive cost/benefits remain as shortcomings, however continued development of the program will undoubtedly enhance sustainable wood supply and minimize impact on the forest environment.
