Understanding DEFRA’s Role
DEFRA is a UK government department responsible for safeguarding our natural environment, supporting our world-leading food and farming industry, and sustaining a thriving rural economy. One of DEFRA’s primary roles is to prevent the spread of pests and diseases, which can have devastating effects on local ecosystems and economies.
Why Regulation Matters
Plants are not merely decorative; they are integral components of our ecosystem. When plants are moved from one location to another—whether across counties or countries—they can unintentionally carry pests or diseases that local plants have no resistance to. An outbreak of an alien pest or disease can lead to significant agricultural damage, threaten wildlife, and require costly eradication measures.
Example: The Oak Processionary Moth
A pertinent example is the case of the Oak Processionary Moth (OPM), which was accidentally introduced to the UK in 2006 through imported trees. This invasive species has not only caused harm to oak trees across several regions but also poses health risks to humans and animals due to its irritating hairs. The fight against OPM has involved extensive and expensive management efforts coordinated by DEFRA to mitigate its spread and impact.
