Assisted natural regeneration is a forest restoration method that has received more attention in the last decade, mainly in landscapes that have forest remnants and local resilience. Several management actions can be applied, including grass control and biodiversity enrichment through the reintroduction of different species groups. This video aims to demonstrate the operational actions carried out in an assisted natural regeneration experiment in the Doce River basin, in south-eastern Brazil, which consisted of three types of interventions applied in areas undergoing natural regeneration that were set aside 3 to 8 years ago. The treatments were: i) weed control and fertilization of wildlings, ii) weed control + enrichment planting using seedlings of five tree species and iii) weed control + enrichment planting using seedlings of fifteen tree species. The video will show exotic grass control, the delimitation of planting-holes and soil preparation using post hole diggers, tree seedling planting, fertilization of wildlings and planted seedlings, and the preliminary results after 12 months. We will also demonstrate some practical challenges and detail topics related to planning, deployment and monitoring. It consists of an assembly of records filmed during the operations plus a demonstration of how to allocate the seedlings with an animation, all using appropriate captions in English and a list of the challenges and lessons learned at the end of the video. We expect this will contribute to other forest restoration practitioners or researchers who aim to implement similar experiments.
