Estimating Use-Values And Relative Importance Of Amazonian Flood Plain Trees And Forests To Local Inhabitants, Lars P. Kvist, Martin K. Andersen, Martin Hesselsoe, Jerome K. Vanclay

Professor Jerome K Vanclay

Use-values have been advocated as a tool to compare the value of not just individual species, but also of plant families and forest types to local people, in order, for example, to identify species or habitats in need of special management or conservation. We estimated use-values in three forest types (upper restinga, lower restinga, tahuampa) on the Amazon flood plain south of Iquitos (Peru), compared two methodologies, identified the most valuable species and contrasted these valuations with the actual use of forest resources in local villages. A new method for estimating use-values was contrasted with the method of Phillips and …

The Amazon Flood Plain Forest Tree Maquira Coriacea (Karsten) C.C. Berg: Aspects Of Ecology And Management, Gustav Nebel, Jens Dragsted, Thomas R. Simonsen, Jerome K. Vanclay

Professor Jerome K Vanclay

Maquira coriacea is a commercial tree species growing throughout the Amazon flood plain forests. Densities up to 14/ha of individuals, ≥10 cm diameter at breast height (DBH) were observed, corresponding to a basal area of 2 m2/ha and a volume of 38 m3/ha. The primary period of fruiting coincided with the annual flooding, but fruits were also produced in other parts of the year. Seedlings with densities up to 150/m2 were concentrated around mother trees, and the stocks fluctuated much over the year due to mortality caused by flooding and wilting in dry periods. Growth data mainly from nine 1 …
