Evaluating restoration

Long-term flexible monitoring is essential for the validity of a restoration activity.

Constant long-term vigilance is essential to make reforestation efforts successful.

Without ensuring the future of the initial and necessary additional protective measures of a restored ecosystem, the project could be considered as abandoned.

Ways of monitoring:


Natural regeneration: witnessing of recovery;

Comparative photos (with a difference of 10 years);

Use of drones (Shaded relief raster).

Conaf assessments of survival rates of reforestation planting:

Obligatory under the Law on Native Forest

Work of students (interns)

Trap cameras:

To monitor the return of wildlife

Chronicle of nature.


The ecosystem now:

Good natural tree regrowth on the valley floor (soil);

Main forest family – native Nothofagus trees;

Synergies between planted, remaining and regrown forest;

Active and constantly increasing bird life;

Wildlife: 3 families of foxes, pichis, occasional pumas and huemules (habitat repaired), bats (3 species), etc.

Increase of insects after restoration measures: important, as post-fire ecological memory in insects is very low, it’s a sign of some rebuilding of forest resilience;

Many native orchids - sign of rebound of the grassy part of the ecosystem;

Functioning wetlands and pit bogs.

Nature is taking its course, wildlife adopted the area,
A no-fear generation of wildlife is growing.

Criteria of success:

Nature is taking its course;

Wildlife adopted the area, a no-fear generation is growing, relations with animals re: shared forest are restored;

Important species like bats are considered as valuable;

Positive feedback of the ecosystem is transformed into negative feedback;

Signs of auto regulation are visible;
