A Disaster Made Worse by Local weather Change
As local weather change drives extra excessive climate occasions and better temperatures, the environmental circumstances that foster botulism outbreaks have gotten extra frequent. Extended warmth waves, drought, and poor water high quality all contribute to the issue. These outbreaks are not remoted incidents—they’re changing into annual occasions in some areas.
How You Can Assist:
- Report It: In case you see birds which might be unable to fly, holding their heads low, or displaying indicators of paralysis, contact WIRES instantly on 1300 094 737 or report-a-rescue right here
- Keep away from Feeding Wildlife: Leftover meals can rot in heat water, contributing to the circumstances that trigger botulism, please discuss with our feeding wildlife factsheet right here
- Volunteer: We’d love your help, please have a look at the methods you’ll be able to become involved with WIRES.
A Shared Duty
Botulism is a pure phenomenon, however its rising severity is a symptom of wider environmental points that demand our consideration. By appearing early and dealing collectively, we are able to defend our valuable wildlife from this merciless and silent killer.
