Estimating red deer Cervus elaphus population density using drones in a steep and rugged terrain

Wildlife Biology, EarlyView.
Precise and accurate information about population density, crucial for wildlife management, is difficult to obtain for elusive species living in dense forests or steep and inaccessible terrain. Using unmanned aerial vehicles (UAVs), we developed a method for obtaining absolute population estimates of ungulates living in steep, rugged, and partly ...

In situ measurement of Scots pine needle PRI [PDF]

Plant Methods, 2017
The Photochemical Reflectance Index (PRI) calculated from narrow-band spectral reflectance data is a vegetation index which is increasingly used as an indicator of photosynthetic activity. The leaf-level link between the status of photosynthetic apparatus and PRI has been robustly established under controlled light conditions.

How to stay wild in a highly domesticated landscape? Spatiotemporal behaviour of wolves in Germany

Wildlife Biology, EarlyView.
Wild animals can adapt to the increasing presence of humans by either becoming accustomed to it or by avoiding humans by spatiotemporal separation. The return of the wolf to the German lowlands raised the opportunity to study wolf behaviour in one of the most densely populated and fragmented countries in Europe, in an area where topography offers no ...

Long-term development of experimental mixtures of Scots pine (Pinus sylvestris L.) and silver birch (Betula pendula Roth.) in northern Britain

Annals of Silvicultural Research, 2016
The Caledonian pinewoods of northern Scotland are a priority conservation habitat in Europe which are dominated by Scots pine (Pinus sylvestris), but varying proportions of a number of broadleaved species such as silver birch (Betula pendula) can occur ...

The effects of moose and pine density on browsing damage in Swedish pine forests

Wildlife Biology, EarlyView.
Moose Alces alces is a culturally and economically important game species in Sweden, but their browsing on regenerating Scots pine trees Pinus sylvestris often causes extensive damage to the production and quality of timber. Forest and wildlife managers are faced with the dilemma of how to reduce damage to timber trees while also supporting moose ...

Linking telemetry data with forage availability maps advances information for moose management

Wildlife Biology, EarlyView.
Evidence‐based forest and wildlife management requires precise estimates of forage availability for spatial planning and conflict mitigation. Recently, novel datasets and associated maps have been developed for use in Swedish forest and wildlife management.

CALEDONIAN SCOTS PINE: ORIGINS AND GENETIC STRUCTURE [PDF]

New Phytologist, 1986
SUMMARYMonoterpene and isozyme loci, used as markers to study the genetic structure of Scots pine (Pinus sylvestris L.) native to Scotland, showed that the endemic populations are not genetically impoverished, in spite of severe contraction in range and numbers as a result of both natural and anthropogenic causes.

Assessing the accuracy of field‐based versus laboratory methods for determining the age of roe deer

Wildlife Biology, EarlyView.
Accurate age determination in roe deer Capreolus capreolus is essential for selective harvesting and informed population management, yet field‐based methods widely used by hunters remain imprecise. This study compared field‐based and laboratory age determination methods in 204 harvested roe deer, categorized by sex and habitat type (forest versus open ...

Sensitivity of Picea abies to butt rot in pure stands and in mixed stands with Pinus sylvestris in southern Sweden

Silva Fennica, 2002
Repeatedly sampled data from permanent experimental plots in southern Sweden were used to model butt rot development in Norway spruce growing in pure stands and in mixed stands with Scots pine.

Habitat selection of moose in Sweden in managed boreal forests with Pinus contorta and P. sylvestris

Wildlife Biology, EarlyView.
Human land use can take advantage of using exotic species to increase financial benefits. However, the use of exotic tree species might affect ecosystem functioning, potentially including the habitat use and movement behaviour of animals, modifying their ecological impact, and interactions with human land use.
