The Congress was sponsored by the Island Coun- ci1 (Cl~hildo Tnsul~r) and toolr place be.twea 13 and 18 April 1973. Twenty six lectures were given on such subjects as flora, conservation, herbaria, and inventories. During a joint excursion participants were introduced to the main plant communities exis- ting on Gran Canaria, Although the principal purpose of the mee,ting was to bring logether al1 bolanists whose work and interest, directly or indi- rectly, relates to the vegetation of the Macaronesian Islands, and to review progress of the “Flora Macaronesica” project, conserva- tion of the ve8getation with its high percentage of endemics re- ceived considerable attention. The urgent need to protect the large number of endangered species and to preserve uniquc communitics and landscapes on the islands gave rise to the prepara,tion and appromal of a general “Appeal” (see “Proposals and decisi’ons”). Thi’s will be widely circulated and brought to the atten,tion of institutions and govern- ments concerned. A communication from IUCN/WWF was read, informing the members of a grant all’ocated for a survey of the natural resources in the eastern Canary Lslands. It was also agreed to create a Macarone,sian Eotanical Associla- tion which would ensure the direction and continuity of the pro- grammes. The Congress received much public interest and was reported on daily and at length by al1 local inlormation media. Summari- zing reports were also publiskd in “Nature” (val. 243:261) and in the “Bulletin IUCN” (vol. 4:23). Official speeche’s pronounced have been published in ful1 in INoca newspapers. -7- LIST OF PARTICIPANTS ALEMANIA Mattick, Prof. Dr. F.; Botanischer Garten und Museum, Berlin-Dahlem Milbradt, J., cand. phil.; Botankches Institut, Universität Erl,angen-Nürnberg F’aul, I’rof Dr. F.; Eotanischm Institut, Univcrsität Bonn Voggenreiter, V., cand. rer. nat.; Botanisches Institut, Universität Erlangen-Nürnberg DINAMARCA Hansen, A., cand. mag.; Botanisk Museum Keben’havn FRANCIA Gagnieu, Prof. Dra, A.; Institut Bo,tani,que, Université Strasbourg Linder, Prof. Dr. R.; Institut Botlanique, Université des Sciences Lille GRAN BREBTAÑA Aldridge, 4.
