Invasive species are plant and animal species that are not native to Latvia, threaten native species and their habitats, cause economic loss or are harmful to human health and the environment. What makes invasive species undesirable and dangerous is that they most often have no natural competitors or enemies to control their spread, resulting in invasive species becoming dominant in the environment, suppressing native species and spreading unhindered over ever wider areas.

To ensure coordinated control of invasive species across the European Union (EU), in 2014 the European Parliament and the Council adopted Regulation 1143/2014 on the prevention and management of the introduction and spread of invasive non-native species, binding for all Member States.

Invasive plant species from the European Union, as well as from Latvia, are listed in several implementing regulations of the European Commission. In Latvia, the most common invasive plant species listed in the Regulations are Sosnowsky's hogweed (Heracleum sosnovskyi Manden) and Himalayan balsam (Impatiens glandulifera Royle).

The Ministry of Environmental Protection and Regional Development is responsible for the implementation of these Regulations in Latvian legislation and their integration into Latvian environmental policy.

The State Plant Protection Service is the responsible authority for the detection, control and eradication of Sosnowsky's hogweed in Latvia. The State Plant Protection Service's National Information System for Crop Monitoring contains information on 10 782,96 ha (09.11.2020 data) of areas infested with Sosnowsky's hogweed, which is the most comprehensive, complete and up-to-date information available on the distribution of the Sosnowsky's hogweed.

Reporting about other invasive plant and animal species:

The public is encouraged to report sightings of plant or animal species in the wild or in their home gardens by photographing the species and uploading the photograph to the database, where the specialists of the Nature Conservation Agency under the Ministry of the Environment and Regional Development will help identify the species, and inform the nearest Nature Conservation Agency regional administration.
