Invasive Pflanzen

Observations of invasive plant species (solid dots) in and around Karlsruhe, crowdsourced from iNaturalist, a global citizen-science database. Invasive plants, also known as neophytes, are species that have been introduced to a new area and spread aggressively, often outcompeting native vegetation and disrupting local ecosystems. The specific species were identified during the workshop ‘On displacement and adaptation’. A noticeable pattern emerges from the data: many of these invasive plants are concentrated along Karlsruhe's rivers, the Alb and Pfinz. This is because waterways often act as natural corridors that facilitate the spread of seeds and plant fragments.
