Random forests have emerged as a versatile and highly accurate classification and regression methodology, requiring little tuning and providing interpretable outputs. Here, we briefly outline the genesis of, and motivation for, the random forest paradigm as an outgrowth from earlier tree-structured techniques. We elaborate on aspects of prediction error and attendant tuning parameter issues. Ho...

Research gaps in understanding flood changes at the catchment scale caused by changes in forest management, agricultural practices, artificial drainage, and terracing are identified. Potential strategies in addressing these gaps are proposed, such as complex systems approaches to link processes across time scales, long-term experiments on physical-chemical-biological process interactions, and a...
UK forests and woodlands are often of considerable value to biodiversity. There is now a growing need to evaluate the impacts of forest management on biodiversity, in order to maintain and enhance the wildlife value at the landscape scale. The development of biodiversity evaluation tools will enable forest and land managers to make informed choices at this scale in order to provide sustainable ...

The delivery of reactive forms of nitrogen to the environment through the sum of agricultural and industrial activities now exceeds that from natural processes. Potential negative effects on forests were first proposed in 1985, and in the ensuing two decades, the process of N saturation has become a well-established and generally understood phenomenon, with a few remaining, significant unknowns...
