Northwestern Costa Rica - Lomas Barbudal Biological Reserve Reserva Biológica Lomas Barbudal

The Lomas Barbudal Biological Reserve covers 2,279ha/5,629ac of land, about 70% of which is deciduous forest. Within the forest are several species of endangered trees such as mahogany rosewood, and the local yellow cortez. There is also tropical dry forest (trees shed their leaves in the dry season) found in Lomas Barbudal as well as riparian forests along the Cabuyo River that flows within park boundaries.

This reserve is also locally famous for its abundance of insect species, of which there are at least 250 species of bees alone. Other insects found in the reserve are wasps, butterflies, and moths.

At least 202 species of endangered birds have been recorded in the reserve, such as the king vulture, jaibiru stork, and scarlet macaw. Mammals include coatis, white-tailed deer, howler and white-faced monkeys. A small museum is found at the reserve entrance.
