Biological control of forest pests

In the Chilean Central Zone exists a considerable surface with plantations of exotic species. Much of these are being permanently attacked by forest pests, many of them introduced from abroad, and from time to time intensifying.

This is mainly due to two reasons:

The low rainfall and its semi-arid nature, make the ecosystems more fragile, especially those constituted by introduced or exotic plant species, therefore, they do not count with the natural controlling agents that have developed in their place of origin.

In the Central Zone of Chile, due to the ports, enters a greater flow of merchandise in the country, therefore being very difficult to control a possible entry of new pests.

Bosques del Norte has signed a Mutual Cooperation Agreement with the Agricultural and Livestock Service (SAG), belonging to the Ministry of Agriculture, whose purpose is to be an active part in all initiatives of Prevention and Control of Forest Pests in the Central Zone. As a result of this Agreement, Bosques del Norte actively participates in the coordination groups organized by SAG to manage these matters.

Our service in this area is to diagnose, evaluate the damage of the pest, present a technical and economic proposal of biological control, application of biological control and finally an evaluation of the impact of the application.

Reforestation with native and exotic species

According to the framework of the Law on Forest Development and Native Forest, Bosques del Norte carries out forest plantations in the Central Zone, either with native or exotic species.

These plantations normally originate by the following reasons:
- Commercial or environmental interest of an owner.
- Obligation in the form of compensation associated with another industrial project, real estate, energy, mining, etc.

Bosques del Norte develops plantation activities in either of these scenarios, and may also suggest and recommend the species to be planted and the silvicultural techniques to be applied in this plantation to ensure its successful development.

Management of native sclerophyll forests

Our work seeks to make interventions to improve the phytosanitary and developmental status of native sclerophyll forest, typical of the Central Zone of Chile, which has been subjected to heavy extraction or destruction of its biomass. The forest has also been a permanent victim of forest fires, which together with human extraction, are the cause of the deteriorated state of these forests that have survived thanks to their high ability to resprout.
