🟠 ORANGE - Serious Danger

Validated Framework (v8.6)

TAI Parameters

Toxicity (T)

Animal (A)

Invasive (I)

Hazard Score

14.7

TAI Code: 453

Core Indices

FXTCHDECOVET

Additional Information

Documented Deaths

Status

Alien

Conservation Status (IUCN)

Scientific Justification

T=4: Cyanogenic glycosides (prunasin, amygdalin) → HCN release; severe poisonings documented; deaths rare/not robust → below T=5 threshold.

A=5: Multiple veterinary lethal cases (dogs, cats, equids, small ruminants); all parts toxic; withered leaves remain dangerous → VET flag mandatory.

I=3: Dense understory formation, suppression of native regeneration in forests/edges; not on EU 1143/2014 → ECO flag mandatory.

Core Indices: FXT (rapid onset), CHD (attractive berries), CLN not assigned (criteria A–E not met).
