Secondary forests comprise a large and growing proportion of the forest cover in the tropics and are very important at the local, national and regional levels for a wide range of products and environmental services. However, knowledge and expertise regarding secondary forests is still limited, and they are inadequately addressed in forest policy, planning and research.

Permanent sample plots (PSP) are an important tool in monitoring forest dynamics and change. In Malinau Research Forest, East Kalimantan, 24 PSPs of 1 ha each were established and all trees with dbh = 20 cm were identified and their diameters were measured in 1998 prior to logging operations and were re-assessed in 2000 and 2004. Two logging systems were implemented during that period: reduced-impact logging (RIL) and conventional logging (CNV).

This paper provides the general objectives of the special issue: secondary forests in Asia: their diversity, importance and role in future environmental management. It provides a brief overview of the renewed attention to tropical secondary forests and sketches the history of research on this subject.

The diversity of C&I sets is often a cause for uncertainty and confusion, and probably one of the reasons for the still unsatisfactory acceptance of C&I as a support for implementation of sustainable forest management so far. In order to halt this erosion of confidence in C&I the presented paper evaluated the diversity of five C&I sets (CIFOR, ACM, FSC, ITTO and Tarapoto) relevant for the Brazilian Amazon by analyzing frequencies of C&I in relation to parameters about content and quality.

L’archipel des Comores qui accède à l’indépendance en 1975 dans des conditions difficiles a ensuite trouvé des réponses contribuant à la paix civile en généralisant des expériences locales de gestion patrimoniale qui ont pu faire l’économie de réformes politiquement et socialement incertaines.
