Keep your eyes peeled for tree pests and diseases

It’s a prime time of year to start spotting pests and diseases that can affect the health of trees with the help of the OPAL tree health survey.

The survey, which is taking place across the UK for a second year, asks the public to report their findings – good or bad – and keep their eyes peeled for the ‘Most Unwanted’, six pests and diseases which could pose a serious threat to our trees.


Discover what lies beneath your lawn

It is one of the world’s most precious natural resources and is vital for growing the food that we depend on for survival.

As milder temperatures begin to arrive, it’s the perfect time to discover the world beneath your lawn by taking part in the OPAL soil and earthworm survey.
