In recent years, many spruce (Picea abies (L.) H. Karst., Pinaceae) forests have been severely affected by bark beetle (Ips typographus L., Coleoptera: Curculionidae) outbreaks in the Southern Alps, but their ecological impacts remain poorly studied.

Evaluation of drone system for thinning operations–a case study in Sweden
Abstract Thinning operations in forestry typically involve a two‐machine system (TMS) with a harvester and a forwarder. Its productivity in different forest conditions is well documented. To date, drones have been used for data collection and surveillance but not as an alternative to a TMS.

Natural disturbances in the forests and bark beetle outbreaks over the period 2015-2024 in the Rhodope Mountains, Bulgaria [PDF]
Damage caused by abiotic factors (snowfalls, snowbreaks, windfalls and windbreaks) and by bark beetle outbreaks was studied over the period 2015-2024 on the territory of four State Forest Enterprises (SFEs) and two State Hunting Enterprises (SHEs) at the

ABSTRACT Biological control in high tunnel systems can be optimised by matching predator species to seasonal environmental conditions. We evaluated the predatory efficacy of syrphid flies (Toxomerus marginatus (Say), Eupeodes americanus (Fabricius)) and lacewings (Chrysoperla carnea (Stephens), Chrysoperla rufilabris (Burmeister)) across laboratory ...

The eight toothed spruce bark beetle (Ips typographus) plays an important role in spruce forests of Croatia, in the same way as it does in the rest of Europe wherever spruce grows. The size and intensity of its outbreaks is considerably lower though, and

Europe is one of the most forest-rich regions in the world, with forestry mainly based on the management of coniferous trees. However, the spruce forest ecosystem is vulnerable to several disturbance agents. In particular, bark beetle outbreaks have been

ABSTRACT Norway spruce will likely remain an important tree species in Europe over the next few decades despite efforts to transform forests and reduce its distribution range more to its natural range. Consequently, Ips typographus will remain one of the most relevant forest pests the management of which will become increasingly challenging due to ...

ABSTRACT Invasive species pose a serious threat to biodiversity and result in significant economic costs. Although much effort is devoted to understanding invasive processes, some aspects are poorly understood, such as the early stages of invasions and the reasons for invasion failure.
