The role of predation in the decline and extirpation of woodland caribou [PDF]
, 2020 To select appropriate recovery strategies for endangered populations, we must understand the dynamics of small populations and distinguish between the possible causes that drive such populations to low numbers. It has been suggested that the pattern of population decline may be inversely density-dependent with population growth rates decreasing as ...

The Journal of Wildlife Management, EarlyView.Caribou forage lichens were present in post‐burn lodgepole pine stands multiple decades before stem‐density was likely open enough to attract wintering caribou. We posit that the prolonged self‐thinning of lodgepole pine after fire may be a greater limiting factor than lichen abundance for habitat recovery in lodgepole pine forests.

Defining subspecies, invalid taxonomic tools, and the fate of the woodland caribou
Rangifer, 2007 If my argument is valid, then true woodland caribou are only the very few, dark, smallmanned caribou scattered across the south of caribou distribution. They need the most urgent of attention.

A survey of the coverage, use and application of ancient woodland indicator lists in the UK [PDF]
, 2009 This report presents the results of a survey into the current use of ancient woodland indicator species lists in the UK. The idea of using species particularly vascular plants as indicators of ancient woodlands can be dated back to the 1970s and the work

Reindeer grazing induces spatial and functional shifts in root systems of boreal pine forests
Oikos, EarlyView.The spatial distribution of roots, laterally and vertically, is critical for nutrient and water uptake and for driving root‐associated carbon inputs and turnover. Large herbivores, such as reindeer, influence ecosystems belowground by altering aboveground vegetation composition and soil microclimate.

Sustainable Development, EarlyView.ABSTRACT Risk management has evolved to analyze risks in a systemic way, integrating local knowledge with the abstract concept of resilience, which is now an imperative for vulnerable and exposed communities. However, existing decision‐support tools are mainly focused on technical‐functional aspects and, although based on rigorous and scientific ...

The identification of ancient woodland: demonstrating antiquity and continuity - issues and approaches [PDF]
, 2009 This report presents an overview of the various types of evidence which can be used to determine whether a woodland site is likely to be designated as ‘ancient’ and discusses how these can be used as part of the decision making process.
