The Butalcura reserve is a 1.081-hectare field, in the center of the large island of Chiloé in an area with a predominance of native forest, rivers, springs, and wetlands with pompon-type moss.


The field borders 10.7 kilometers with the Butalcura river to the west and to the east with a public road parallel to Route 5 south.
Its topography is mostly flat, about 40% of the field is covered by adult native forest and 22.8% are areas covered with pompom and scrub. The rest of the field is mostly saplings of medium age.
It is located 18 kilometers from the main airport of Chiloé, 35 kilometers from Castro, 66 from Chacao, crossing to the mainland, and 138 from El Tepual airport (Puerto Montt).
The field has a master plan for the development of a subdivision-conservation project with 79 lots with registered pre-roles.
