“…Herbaceous weed control with herbicides has become closely associated with FVM. It is the top of the pyramid; it may be very costly, but it is also every effective (Vasic et al, 2012). The general public has also come to associate FVM with chemical control and this has resulted in public perceptions of FVM sometimes not enhancing sustainable forestry practices.…”

Forest vegetation management has evolved as a recognized component of intensive forest management practice. It involves the management of competing vegetation necessary to obtain the high yields expected in modern forest plantations via control of interfering plants that influence regeneration outcome, impact timber stand development, and limit native plant and wildlife diversity. It includes cultural control, fire control, mechanical control, biological control, and chemical control. The public perception of forest vegetation management, especially chemical control, is sometimes negative due to health and environmental concerns. It is an important tool in the forest management alternatives available to consulting foresters managing family forest lands (the vast majority of private forest land in the United States). We report on a study that addresses the motivations of family forest owners that implement forest vegetation management practices and the motivation of those who chose not to implement after forester recommendations to do so. For those who do implement forest vegetation management, improvement of wildlife habitat and increased timber growth was the main motivation. For those who did not, cost was the main concern. Size of forest holding plays a major role in determining who will practice intensive forestry.

“…In forests, most herbicides were used in the 1960s and 1970s. At the time, herbicides were used, among others in beech stands (Fagus sylvatica L.), when in the years of seed sowing, it was necessary to prepare the soil (Gorzelak 2000;Vasic et al 2012). Herbicides were also used in poplar plantations, as well as in coniferous and deciduous conifers, mainly for the elimination of sprouts or young natural regeneration of birch (Betula pendula Roth.)…”

The use of herbicides to regulate weeds in forest nurseries and crops in Poland

Weeds competing with seedlings of trees for nutrients, moisture, light and space, drown out their growth in nurseries and forest crops. Currently, in forestry, weed control is mainly carried out in forest nurseries, less often during the preparation of the area intended for afforestation, but sporadically in forest crops. The most important species of weeds threatening seedlings of forest trees include Senecio vulgaris, S. silvaticus, Deschampsia caespitosa, Pteridium aquilinum, Agropyron repens, Calamagrostis epigeios and Equisetum arvense. In Poland, herbicides have the largest share (about 50%) in the sale of plant protection products, but the scale of their use in forests is small, compared to agriculture. In 2012, 915 herbicides were registered in the country, out of which only 14 products (0.5%) were for use in forestry. In the years 1999–2019, 31 herbicides were registered for the protection of forest nurseries and crops, which included 13 active substances belonging to 11 chemical groups, of which 9 active substances have been used up to now. Most herbicides (15–16) were used in the years 2004–2006, the lowest in 1999–2000 and in 2014 (4 products). The most popular active substance has been glyphosate contained in 18 products.

“…Research by Rutkowski (2004) has shown that the disturbed and ruderal habitats are most suitable for E. annuus. Studies of species dynamics in Lithuania suggest that in the initial phases of invasion, which started a few decades ago (Tunaitien_ e et al, 2014), the species prefers sites such as urban areas and old cemeteries (Patamsyt_ e et al, 2013), while in later invasion stages it appears to be successful and a frequent invader in weedy sites and damp woodlands (Kova cevi c et al, 2011;Vasi c et al, 2012). In habitats where E. annuus was detected, it most commonly grows together with nitrophilous plant species such as Urtica dioica L., Artemisia vulgaris L., Rubus caesius L., Daucus carota L. and C. canadensis (L.) Cronquist.…”

“…The invasion of E. annuus can affect biodiversity, and, consequently, invaded ecosystems may suffer from significant loss of economic and cultural value (Anastasiu & Negrean, 2005;Kube sov a et al, 2010). Erigeron annuus is a threat to biodiversity in wet habitats, natural and extensively managed habitats, forest and floodplain woods and swamps, as the plant is able to successfully compete directly with native species for space, light and nutrients (Vasi c et al, 2012;Zelnik, 2012). Erigeron annuus and the tree species Robinia pseudacacia are the most frequent invasive alien plant species in grasslands in Austria (Essl & Rabitsch, 2002) and the most frequent invasive alien plant species in riparian zones around standing waters in Slovenia (Zelnik, 2012).…”

Current situation with invasiveErigeron annuus(l.) Pers. (daisy fleabane) in the Republic of Macedonia

Detailed surveys of populations of Erigeron annuus (L.) Pers., an invasive plant species native to Eastern North America, were made in three locations in north‐western, northern and eastern parts of the Republic of Macedonia. The population densities were not quantified, but several stands of different sizes were found. A rapid ecological risk assessment, mainly based on knowledge of invasion histories in South‐Eastern and Central European countries, showed that this species is a serious threat to Macedonian biodiversity, particularly in the north‐western part, where monospecific stands of E. annuus were recorded. Biological invasions of E. annuus affect biodiversity worldwide through its rapid growth and high seed production, phenotypic plasticity in the native range with regard to the availability of soil nutrients and release of compounds to the soil over the period of plant growth. Consequently, invaded ecosystems suffer from significant loss in economic and cultural value.
