I like what they call this Hawthorn (likely Crataegus monogyna, known locally as Espino Albar)bush: The "Bear's Pantry"
Essential Food Source: These berries (called majuelas) are a critical high-energy food source for the Cantabrian Brown Bear. As they prepare for hibernation, bears move through these mid-altitude slopes to feast on the fruit. While edible for humans, they are quite mealy and tart—best left for the local wildlife! THUS, not as good as huckleberries. If their bears only knew.
