Artemisia verlotiorum

Chinese mugwort

Chinese mugwort (Artemisia verlotiorum) is a perennial plant that originally comes from the Asian regions around China. It is characterised by its upright growth habit and its height of about 50 to 150 centimetres. The leaves are grey-green and finely pinnate, which gives them a delicate and filigree appearance. The yellowish inflorescences appear in late summer to autumn and give off a scent of camphor. The Chinese mugwort is known for its adaptability to different soils and is considered a pioneer plant, colonising nutrient-rich, disturbed soils. Due to its high vegetative spreading potential, it often forms dense monospecific stands and thus displaces native plant species.

Types of damage

Ecological damage

Artemisia verlotiorum can influence natural ecosystems and displace native plant species as it spreads rapidly vegetatively. Chinese mugwort establishes itself especially in ruderal areas. As a pioneer plant with high light requirements, it is a strong competitor to other plant species.

Economical damage

In vineyards, Artemisia verlotiorum can cause crop losses as it prefers sunny sites and competes for resources such as water, nutrients and light.

Region of origin

China, North East Asia

Introduction vectors

Agriculture

Artemisia verlotiorum can be introduced as a by-product in seed or feed batches.

Horticulture

The plant can be introduced into new areas through the garden plant trade. Chinese mugwort does not have a very ornamental appearance, but has been cultivated for the medicinal sector in the past.

Miscellaneous

Family

The daisy family (Asteraceae), also known as Asteraceae or Compositae, is one of the largest plant families with more than 23,000 species in about 1,620 genera. A distinguishing feature is their complex inflorescence, which consists of many small individual flowers forming a "basket". This family is globally distributed and contains species ranging from annual plants to perennial shrubs and trees. Well-known representatives are the sunflower, daisy, dandelion and many species of chrysanthemum. Many asteraceae are important for honey production, and some, such as artichoke and endive, are important crops.

Climate change

Artemisia verlotiorum has not yet filled its potentially suitable habitat under current climate conditions. It benefits from climate change because in the future its potentially suitable habitat will increase. The environmental factors that most influence its spread are soil type, road infrastructure, temperature in summer, land use type, and precipitation in summer.

Habitat suitability under current climate conditions

These habitat suitability maps show for Artemisia verlotiorum where suitable habitat conditions exist.

The map on the left shows this for current climate conditions. Below this are maps for the time classes 2040-2060 and 2061-2080, in which three different emission scenarios can be selected.

The slider at the top left allows you to adjust the opacity of the map to make orientation easier.

By clicking on the respective quadrant, information on the environmental conditions present in it can be called up.

Habitat suitability 2040 - 2060

2040-2060: In the RCP2.6 scenario, GHG emissions are expected to peak by 2040 through comprehensive mitigation measures and to decline rapidly thereafter. By 2060, global warming would stabilise at about 1.5°C above pre-industrial levels. Subtle changes in precipitation patterns could vary regionally, with some areas facing increased drought and others increased precipitation.

2040-2060: Under RCP4.5, GHG emissions would continue to increase until 2040, but stabilise at a high level thereafter. By 2060, there could be a global temperature increase of about 2°C above pre-industrial levels. This scenario would likely cause moderate changes in precipitation patterns, with potential regional differences.

2040-2060: Under RCP8.5, which assumes continued intensive use of fossil fuels, greenhouse gas emissions would rise sharply by 2060. The global temperature increase could be around 2.5-3°C. In this scenario, significant changes in precipitation patterns could occur, with an increased likelihood of extreme weather events.

Habitat suitability 2061 - 2080

2060-2080: By 2080, global warming could be limited to below 2°C in the RCP2.6 scenario, provided emission reductions are consistently pursued. Impacts on precipitation patterns would likely stabilise, although regional variance would remain significant.

2060-2080: In the RCP4.5 scenario, global temperatures would continue to increase and could be around 2.5°C above pre-industrial levels by 2080. Changes in precipitation patterns would likely increase and regional differences could become more pronounced.

2060-2080: Under RCP8.5, global temperatures could rise by more than 4°C above pre-industrial levels by 2080. Precipitation patterns would be expected to change significantly, with further increases in the frequency and intensity of extreme weather events. This would have far-reaching impacts on ecological and socio-economic systems.
