Full-text available
The importance of forests in nature and artificial environments has been widely recognized, in the context of global changes. Forest structures and functions strongly depend on but concurrently influence environmental conditions. Such processes involve interactions between forest and environment, which are highly complex at the different spatial an...

Water sustenance in streams and rivers depends on the integrity of the catchment (watershed), as vegetation helps in retarding the velocity of water by allowing impoundment and recharging of groundwater through infiltration. Forests with native vegetation act as a sponge by retaining and regulating water transfer between land and the atmosphere. He...
Article
Full-text available
The lowland ponds, depressional submerged areas that are fed by runoff from surrounding uplands and then send overflows to downstream water bodies, are recognized as biogeochemical hotspots of nitrogen (N) removal. Despite their important role in mitigating N pollution, very little is currently known about their potential for N removal, particularl...

Forest expansion can make an important contribution to the 2015 Paris Agreement, through offsetting Greenhouse gas (GHG) emissions. EU, UK and Scottish forest policy encourages substantial forest expansion. Unfortunately, policy is still inadequately informed by high resolution data, and often assumes a fairly homogenous landscape, uniformly suitab...

Research that illuminates causes of urban forest storm damage is valuable for planning and management. However, logistical and safety concerns often delay post-storm surveys in urban areas; thus, surveys may include observations with unverified sources of damage. While this uncertainty is often ignored, it can make up a high proportion of the numbe...
