This recent expedition was a great learning experience for all the participants, from the young botanists to the more experienced plant taxonomists, and will stand us in good stead for future regional expeditions planned within the project and beyond. The project’s philosophy is Editorial “learning by doing”, and we certainly learnt by doing on this recent expedition. The next regional Welcome to the 12th edition of SABONET News, the botanical collecting expedition is scheduled to be official newsletter of the Southern African Botanical held in Mozambique, probably in 2001, and will be Diversity Network Project, more commonly known as much, and possibly even more of a challenge, as SABONET.

Readers can look forward to three new numbers in the SABONET Report PROFILE Series: an inventory on southern African plant taxonomic and diversity expertise, the results of a Augustine Charles Chikuni botanic gardens needs assessment survey that was conducted within the region last year, and a manual on environmental interpretation in botanic gardens. A couple of important international meetings will be taking place around the world over the next couple of months, and we hope to report on each of them in the August edition of our newsletter. COP V (5th Conference of Parties to the Convention on Biologi- cal Diversity) is being held in Africa (Kenya) for the first time and the International Botanic Gardens Congress is scheduled to be held in June in Asheville, North Carolina, USA. The New Interna- tional Agenda for Botanic Gardens in Conservation, to which the SABONET Project and the region’s botanic gardens contributed in June 1999, will be launched at this meeting.

So let us resume old-fashioned expeditions at a quickened pace, solicit money for permanent field stations, and expand the support of young scientists—call them “naturalists” with pride—who by inclination and the impress of early experience commit themselves to deep knowledge of particular groups of organisms”.
