Assisted Natural Regeneration (ANR)

Similar names: Pruning, Kisiki Hai, Managed regrowth

Assisted Natural Regeneration (ANR) is a simple, low-cost forest restoration method that can effectively convert deforested and degraded lands into productive forests and rangelands. The method uses a blend of active planting and passive restoration techniques, which help vegetation to naturally recover by eliminating barriers and threats to their growth. ANR is similar to Farmer-Managed Natural Regeneration (FMNR), with the difference that ANR applies to degraded forest lands and rangelands while FMNR is usually practised on croplands. Overall, ANR mimics the natural systems and habitats by supporting the land processes through assisted regeneration. 

ANR is a flexible restoration approach and could be adapted to various contexts and objectives. A set of ecosystem restoration techniques are being facilitated, to eliminate obstacles to plant growth and survival. Those could vary depending on a range of factors, such as location, land type, restoration goal, etc. Hence, local community engagement is crucial for successfully implementing and managing ANR. Their knowledge of the land and ancestral traditions offers the best indication of what techniques and practices would be most beneficial. The most common ANR techniques are visualized in the figure below.

In comparison to other regeneration techniques such as tree-planting campaigns, ANR has comparatively low implementation and maintenance costs. The method could be applied on a local and larger scale level, with some areas and contexts being more favorable than others when it comes to implementation (see Requirements). However, where implemented, ANR can create jobs and bring income to local communities, as the implementations would require establishment and maintenance.
