Ash Lichen Alert

Rhybuddion Cennau Ynn

These data identify 10x10m, 100x100m and 1000x1000m areas where a Threatened Lichen has been recorded on Ash. The dataset is designed to allow land managers to rapidly identify whether they need to consider rare lichens when working with Ash trees, especially if they are considering felling a tree because of Ash Dieback.

Mae'r data hyn yn nodi ardaloedd 10x10m, 100x100m a 1000x1000m lle cofnodwyd Cen dan Fygythiad ar Ynn. Dyluniwyd y set ddata i ganiatáu i reolwyr tir nodi'n gyflym a oes angen iddynt ystyried cen prin wrth weithio gyda choed Ynn, yn enwedig os ydynt yn ystyried cwympo coeden oherwydd lladdwr yr ynn (Hymenoscyphus pseudoalbidus).

Lineage: Most data are from BLS Rare and Threatened Lichen Records: Wales (British Lichen Society; CC-BY); a minority are from NRW Regional Data: North Wales (Cofnod - North Wales Environmental Information Service; OGL), Natural Resources Wales Regional Data: Mid-Wales (BIS for Powys and Brecon Beacons National Park; OGL), NRW Regional Data: all taxa (sensitive species only), West Wales (West Wales Biodiversity Information Centre; OGL) and NRW Regional Data: South East Wales Non-sensitive species (South East Wales Biodiversity Records Centre; OGL).

Key

- Red shows where a rare lichen is growing on an ash tree: these are the most important localities for action to prevent damage to a rare lichen.

- Pink shows where a rare lichen that often grows on ash has been recorded, but where the record does not specify the host tree. Consultation with Natural Resources Wales is advisable in these cases, especially in SSSI, because the rare lichens may be growing on ash.

- Yellow shows where a rare lichen that often grows on ash has been recorded on other host trees.
