Resin yield of Pinus nigra and Pinus sylvestris in the Slovenian Karst
Acta Silvae et Ligni, 2018 The aim of our research was to study the impact of various environmental factors on the resin production of pines in the Slovenian Karst. Five plots were established % three in Pinus nigra (Arnold) stands and two in Pinus sylvestris (L.) stands.

Monitoring GPS‐collared moose by ground versus drone approaches: efficiency and disturbance effects
Wildlife Biology, EarlyView.Efficient wildlife management requires precise monitoring methods, for example to estimate population density, reproductive success, and survival. Here, we compared the efficiency of drone (equipped with a RGB camera) and ground approaches to detect and observe GPS‐collared female moose Alces alces and their calves. We also quantified how drone (n = 42)

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 ...

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.

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 ...
