Conservation and threats
The Azores were discovered and settled by Portuguese mariners in the 15th century. Prior to settlement the islands were mostly covered in forest. The settlers cleared most of the islands' forests for agriculture and pasture. Domesticated cattle, sheep, and goats were introduced to the islands, along with the brown rat

'', have spread into wild areas where they displace native plants and alter habitat for native animals.[ The Azores bullfinch relies on a few native plants for food – Azores blueberry and Azorean hawkbit (''Leontodon filii'') in August and September, and Azorean holly in March and April. Loss of these food plants contributed to the species' declining population. Between 2003 and 2008 an EU-funded project removed exotic species and replanted native food plants in the Pico da Vara/Ribeira do Guilherme Special Protection Area on São Miguel, and the local Azores bullfinch population subsequently rebounded.][BirdLife International (2010).

Protected areas
620 km2 (26%) of the ecoregion is in protected areas. Another 20% is forested and outside protected areas.[
