Ynghylch

Introduced from the Mediterranean in the 16th century, the Holm oak is a tall, evergreen tree that has been widely planted. Like our native oaks, it produces acorns (on short stalks) which are dispersed by wildlife. It often survives by the coast, tolerating salt-spray from the sea, but is prone to die or lose its leaves during severe frosts. For this reason, it's more common in the south.

The acorns of oak trees are a favourite food of the brightly coloured Jay; they will often cache their finds for the coming winter, but may forget where they have buried them, allowing the acorns a chance to grow into saplings.

The Wildlife Trusts record and monitor our local wildlife to understand the effects of various factors on their populations, such as the introduction of new species. You can help with this vital monitoring work by becoming a volunteer - you'll not only help local wildlife but learn new skills and make new friends along the way.
