To improve forest restoration results at MBG\u2019s conservation sites, we monitor the outcomes of our work to plant young plants of native tree species on degraded land. Information on species\u2019 survival and growth under specific conditions can help to improve future endeavours of this type at the site but also elsewhere in Madagascar. In 2018 we conceived a pragmatic, standard monitoring protocol that was trialled at four of the sites where MBG supports conservation projects: The Ankafobe Forest, the Analalava Forest, the Pointe \u00e0 Larr\u00e9e Peninsula, and the Oronjia Forest.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

This protocol can be summarized as follows :<\/h3>\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

\n\t\t\t\t\t\t\t\t\t1. Monitoring is carried out in \u00ab restoration units \u00bb which are defined as areas with largely similar vegetation + topography + aspect + type of treatment (e.g. removal of competitive ferns).
2. At the time of planting in each \u00ab restoration unit \u00bb, the number of individuals planted of each species are recorded together with the date of plantation.
3. A minimum of 20 randomly-selected seedlings of each species planted in each \u201crestoration unit\u201d are selected and tagged with unique codes. Exceptionally, when the number of individuals for a species in a restoration unit is less than 20, then all the individuals of that species are monitored.
4. The vertical height of each monitored individual is measured at planting time (T0) and, 12 months later (T1), their condition (dead or alive) and the new vertical height is measured again. The vertical height of the young plant is measured from the soil to the plant\u2019s highest growth point.\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t
