Beijing is using a big data model to identify and track an invasive species that resembles giant dandelions, known as "ecological killers."
During the spring flower-viewing season, the Songzhuang Xiaoyang Park became a popular destination for city residents and tourists, who flocked to photograph fields of "dreamlike plants" growing in large clusters. Along a 400-meter stretch of road, both sides of the green spaces were filled with enormous, peculiar dandelion-like flower heads, whose fuzzy seed balls shimmered softly in the breeze, creating an ocean of crystal-like orbs.
The first to detect the issue was a big data legal supervision model. According to Beijing Daily, authorities have launched a special cleanup operation targeting these unwelcome invaders, known as "long-beaked salsify" (Tragopogon dubius), which gradually encroach on native vegetation. To date, more than 57,000 plants of this species have been removed, covering a concentrated cleanup area of over 68,000 square meters.
