The fields of tree breeding and genetic engineering can be perceived as being antagonistic towards each other—genetic engineers suggesting that tree breeding is too slow and expensive and tree breeders suggesting that genetic engineering is not practical and too expensive. We argue here that both fields have much to offer forestry and the success o...

Emerald ash borer ( Agrilus planipennis ; EAB) has devastated populations of ash ( Fraxinus spp.) trees in dozens of U.S. states and Canada over the past few decades. The continued survival of scattered ash trees known as “lingering ash” in heavily infested natural stands, however, offers evidence of genetic resistance or tolerance to EAB. These su...

Conventions and policies for biodiversity conservation and climate change mitigation state the need for increased protection, restoration and climate change adaptation of forests. Much degraded land may be targeted for large-scale forest restoration, yet challenges include costs, a shortage of regeneration material and the need for restored forests...

The number of global initiatives for forest restoration, and the scope of these initiatives, continues to increase. An important tool for meeting objectives of these global initiatives is reforestation, achieved by natural processes or by tree planting. Worldwide, organizations are challenged to most efficiently and effectively direct resources to ...

The rooting of Allanblackia stem cuttings is typically slow and with the formation of very few roots. Irradiance has positive effects on the relative growth of plants and rooting ability, but there is no information relating to Allanblackia species. Stumps of Allanblackia floribunda Oliv. were grown under three levels of irradiance (2008 µmol m−2s−...

For millennia, natural disturbance regimes, including anthropogenic fire and hunting practices, have led to forest regeneration patterns that created a diversity of forest lands across the USA. But dramatic changes in climates, invasive species, and human population, and land use have created novel disturbance regimes that are causing challenges to...

Desertification and land use pressures reduced forest cover in Inner Mongolia by 3% between 1992 and 2001. These forests primarily form symbioses with ectomycorrhizal fungi, and inventory and conservation of this resource is desirable as one tool to promote forest recovery in the future. We reviewed work on 311 ectomycorrhizal fungal species from p...

Vast areas of hardwood and mixedwood forests of eastern North America have been high-graded in the past and need silvicultural treatments to increase their value and productivity. To rehabilitate a high-graded temperate mixedwood stand, in Quebec, Canada, we used a split–split-split plot design with three replicates to assess different seed-tree an...

Some forest plantations with native species are established in semiarid central Chile to compensate for industrial activities such as those of mining. Two of those operational forest plantations were monitored from age 1 to 3 years-old (2014–2016). Some plant attributes and soil volumetric water content (VWC) were monitored for eight native tree sp...
