HLPF Finds Mixed Progress on SDG 15 IISD - News - 17 hours ago
Delegates noted that the Aichi Biodiversity Targets will not be achieved by their deadline of 2020, casting doubt as to whether sufficient progress is being made toward SDG 15, which shares similar targets. Speakers highlighted, among others, land management as an important issue for SDG 15, the benefits of sustainable forestry and land restoration for mitigating climate change, and the role of biodiversity protection in conflict prevention.
Should Rhinos Be Introduced To Australia? Alert Conservation - News - 2 weeks ago
This is one of those ideas that might seem insane initially, but on reflection is not quite as crazy as it sounds. There are five species of rhinoceros in the world — two in Africa and three in Asia.  All five are desperately imperiled. For rhinos, the world is being rapidly shattered — their savanna and forest habitats destroyed and sliced apart by clearings, fences , roads, and other obstructions. Even worse, they are being slaughtered by poachers for their valuable rhino horn — which is falsely...
In order to invade new ecosystems, invasive alien plants need to cope with different microbial communities. Whilst the ability to avoid antagonists is well recognized, the opportunity to establish mutualistic associations is less known, even in widespread invasive species such as Ailanthus altissima (Mill.) Swingle. We sought to evaluate whether the beneficial effects of arbuscular mycorrhizal fungi (AMF) on Ailanthus seedlings are maintained over time, under prolonged pot limitation. We compared...
Scientific network checking forest health timberbiz - News - 2 weeks ago
The world’s forests are a leading indicator of the planet’s health. They absorb some of the carbon that we emit and protect us from the growing damage of climate change. And they create microclimates around them—cooling their nearby regions and making the local climate more stable. Source: The Daily Beast Scientists who want to understand how healthy the world at large is look to regional forests and, increasingly, they’re looking at the health of these ecosystems globally. One of the ways they...
International trade and travel are the driving forces behind the spread of invasive plant pathogens around the world, and human-mediated movement of plants and plant products is now generally accepted as the primary mode of their introduction, resulting in huge disturbance to ecosystems and severe socio-economic impact. These problems are exacerbated under the present conditions of rapid climatic change. We report an overview of the Canadian research activities on Phytophthora ramorum . Since the...
Forest fragmentation can promote non-native plant invasions by increasing invasive plant seed dispersal and resource availability along edges. These effects can vary based on forest age and may be influenced by differences in traits of native and invasive plant species. To determine how native versus invasive plant species respond to forest edges and forest successional age, we experimentally evaluated germination, survival, and growth of three native and three invasive woody plant species in eastern...
The NorthWoods Stewardship Center is a non-profit conservation organization serving the communities of northern Vermont and New Hampshire since 1989. Our Education, Conservation Corps, and Forest Stewardship programs provide the knowledge and skills needed to understand the northern landscape, make use of its resources wisely, and help sustain vibrant communities and a healthier natural environment. Our Charleston, Vermont campus and 1,450 acre demonstration forest are a destination for outdoor...

Renaturalization treatment in black pine afforestation is an important topic that should be considered. There is a need to favor the evolution of artificial pine forests toward natural forest systems. Overall, this study focused on pine forests, and suggests one typology of clear-cutting (dismantling cutting) on strips, which is associated with different extraction management techniques. Some ecological and environmental aspects associated with renaturalization treatments that have been applied...
The arrival and spread of emerald ash borer (EAB) across the western Great Lakes region has shifted considerable focus towards developing silvicultural strategies that minimize the impacts of this invasive insect on the structure and functioning of black ash (Fraxinus nigra) wetlands. Early experience with clearcutting in these forests highlighted the risks of losing ash to EAB from these ecosystems, with stands often retrogressing to marsh-like conditions with limited tree cover. Given these experiences...
The emerald ash borer, Agrilus planipennis Fairmaire, is invading North America and Europe but has not yet reached its ultimate distribution. Geographic differences in host availability and winter temperatures might affect where this species will occur. In central North America, black ash (Fraxinus nigra) is more abundant than green ash (F. pennsylvanica) at northern latitudes, but much of our current understanding of A. planipennis cold tolerance is based on observations of overwintering larvae...
