The city longhorn beetle (Aeolesthes sarta) (CLB) (Coleoptera - Cerambycidae) is a polyphagous invasive pest of both healthy and suppressed broadleaved trees in central Asia. CLB causes a great degree of damage in the countries of its origin. To understand this pest in a better way, a detailed review study has been conducted to gather all the valuable information related to the CLB. This review study covers the main aspects of the CLB, its morphology, ecology, distribution, damage, and control measures. The life span of the CLB is two years. It is mainly distributed in the central Asian countries and preferably damages broadleaved tree species,...

Black locust is one of the most commonly planted exotic tree species in the world. It has a crucial role in mitigating the negative effects of climate change. Its increment analyses have a key role in forest planning. Increment is added to the wood stock of the forest over and over again, and only this continuous replenishment makes the sustainable forest management possible. This study presents the results of the analysis of periodic annual increment (PAI) by diameter (dbh) and volume (v) of two differently aged black locust (Robinia pseudoacacia L.) stands, growing under similar ecological conditions. The main...

This study was embarked upon to assess forest guards' Knowledge, Attitude and Practice (KAP) behavioural change sequences in Nigeria lowland forest reserves using a structural equation modelling approach. Two research questions were raised and corresponding hypotheses were tested. From the data analysed, it was revealed that both knowledge and attitude variables significantly predicted the behaviour of the forest guards' towards the management of the forest and its resources. Although the attitude variable on its own did not significantly predict the forest guards' behaviours (t = 1.401, P > 0.05), it can be stated that the knowledge...

Information on the structural organization of forest stands obtained on sample plots is the basis for long-term monitoring of post-fire pine forest structure and dynamics in the European North-East. These data can be used as a marker of native pine stands of the European taiga. Here, we studied vertical and horizontal structure in the post-pyrogenic pine forests of Vacciniosum, Vaccinioso-cladinosum and Myrtillosum site types in the boreal forest of the Komi Republic. The type of horizontal structure of uneven-aged forest stands changed with age from grouped to random one. Large trees were randomly distributed on the plot. We observed...
