NEW PUBLICATION ON PRACTICAL EXPERIENCES WITH EX SITU CONSERVATION OF TROPICAL PINES60

Danida Forest Seed Centre (DFSC) and FAO together with national partners in the concerned countries have published "Practical experience with establishment and management of ex situ conservation stands of tropical pines. DFSC Results and Documentation No.1. RD1.61"

Ex situ conservation stands of Pinus caribaea, P. oocarpa and P. tecunumanii were established within the framework of an FAO/UNEP project on forest genetic resources, which was operational between 1975 and 1985. Stands in eight countries, Australia, Brazil, Cte d'Ivoire, India, Kenya, Tanzania, Thailand and Zambia, were assessed in the field in 1996-1999 by national institutions in cooperation with FAO and DFSC.

Some findings of general interest for those countries and institutions planning to establish ex situ conservation stands are listed below:

Efforts have so far focused on pioneer tree species which are relatively easy to propagate and grow in plantations. Establishment and management of ex situ conservation stands of climax species will often require added research on reproductive ecology, seed collection and handling, use of nurse species and mixture of species in general, which may not be available at the present time. This is a challenge which should be addressed in the coming years.
