Invasive alien species threaten biodiversity and related ecosystem services by, for example, displacing native species, changing habitat conditions, and disrupting food networks. As a result of climate change, the number of invasive alien species and the harm caused by them are expected to increase further. At the local level, the impacts on local nature can be significant.
According to preliminary analyses, 70 per cent of the City of Tampere's meadows and landscape fields are home to invasive alien species. According to the law, the city is obliged to take reasonable measures to prevent invasive alien species or their spread. In addition, the city plays a significant role in providing advice and information related to invasive alien species. The prevention of invasive alien species and their spread in the Tampere region is long-term, systematic work.
Other benefits
By controlling invasive alien species, many adverse effects on health, the economy, and ecosystem services can be avoided, such as:
- the spread of bacterial diseases
- allergic reactions and burnlike skin lesions
- decrease in the value of the property
- agricultural crop losses
- growth problems in seedling stands that hinder forestry
- reproductive problems of pollinators
- soil modification and ecosystem dysfunctions, and
- disadvantages that reduce recreational values.
