“…The result of these practices was that, after 15 to 20 years, many of these plantations were under physiological stress, which contributed to a massive outbreak of root rot (Heterobasidion spp.) [26] At the same time, there were increasing outbreaks of defoliating and wood boring insects [30,31], especially in stands growing on rich sites [32]. Altogether, these factors caused significant economic losses and ecosystem changes [5,33].…”

The current nature of forest management in Poland reflects its history and more than 100 years of economic activity affecting forests since independence in 1918. Before that time, different forest management models were used, related to the nature of the Prussian economy in the north of the country, the Russian economy in the central-eastern part, and the Austrian economy in south-eastern Poland. The consequence of these management models, as well as the differing climate zones in which they were used, resulted in varied forest health. Since the end of World War II, forest coverage within Poland‘s new borders has increased from 20.8% to currently 29.6%, mainly as a result of afforestation of wastelands and former agricultural lands. This paper describes changes in the health of forests and their biological diversity in Poland in the context of weather extremes, species composition, forest management, the forest industry, and damage from insects and pathogenic fungi over the last 30 years.

Gypsy moth, Lymantria dispar L., is one of the most important pests of deciduous trees in Europe. In regular cycles, it causes large-scale defoliation mostly of oak, Quercus spp., forests. Government authorities in the most infested countries in Europe conduct large-scale applications of pesticides against gypsy moth. In 1999, a new natural enemy, the entomopathogenic fungus Entomophaga maimaiga, was successfully introduced into a gypsy moth population in Bulgaria. Recent investigations suggest that now E. maimaiga is quickly spreading in Europe. Herein, past studies are reviewed regarding this fungus with special emphasis on its potential for becoming an important factor regulating gypsy moth populations in Europe, focusing on the host's population dynamics in relation to the fungus, the influence of environmental conditions on fungal activity, the influence of E. maimaiga on the native entomofauna, including other gypsy moth natural enemies, and spread of the fungus. Based on this analysis, the potential of E. maimaiga for providing control in European gypsy moth populations is estimated.

“…Germany, Poland (Bt only), the Czech Republic and Slovakia (Roy et al, 1995, Lipa andKolk, 1995) to counter outbreaks of gypsy moth in those countries. In this situation, the unusual nature of the outbreak site (in domestic gardens) posed a number of problems regarding the use of insecticides in this environment.…”

Gypsy moth,Lymantria dispar, outbreak in northeast London, 1995 – 2003

A small outbreak of the gypsy moth, Lymantria dispar (L.), was discovered in June 1995 in the South Woodford area of northeast London, near Epping Forest. The origin of this outbreak remains unknown, but the eggs may have been transported from continental Europe, where major outbreaks occurred in the early 1990s. A risk assessment concluded that severe defoliation by this forest pest was unlikely to occur in the UK under current climatic conditions, but if the gypsy moth did become established, then sporadic damage to amenity tree species could be expected. Therefore an eradication programme was undertaken, which involved determining the extent of the outbreak area via population monitoring, and chemical treatments of any larval infestations, to prevent further spread. A series of targeted publicity campaigns was carried out with the aim of raising public awareness of the pest in the wider outbreak area. Details of gypsy moth finds (egg masses and larvae) and pheromone trap catches (adult males) are given for the years 1995 -2003. Pheromone traps were maintained at a relatively high density (c. 188 per 1 km 2 ) in the immediate outbreak area-and similarly in an adjacent portion of the Epping Forest-and it remains a possibility that some mating disruption has occurred. Although Lymantria dispar persists at this site, the numbers of adult male moths trapped has declined markedly in comparison to the first 2 years (1995 -1996). The outbreak is, however, continuing to persist at a very low level and may be becoming more widely dispersed, albeit very sparsely. It is also possible that observed population trends in terms of pheromone trap catches reflect a natural population cycle, and for these reasons work is continuing in an attempt to eradicate this damaging broadleaf tree pest from the UK.
