COLLECTING

Collecting trips, in which Kew works with host institutions under Memoranda of Understanding, are an essential means of studying and documenting biodiversity in poorly-researched areas.


FIELD WORK IN :
Cameroon


AS PART of a Darwin Initiative project, a team of Kew Assistant Scientific Officers travelled to Mount Cameroon from 8 October to 6 November 1995 to survey rain forestregeneration on two lava flows: the 1922 Idenau flow on the wetter westerly side ofthe mountain and the 1959 Ekona flow on the drier eastern slopes at higher altitude. The data are being compared with studies made in 1938 and 1951 to provide an indication of species succession on these areas of deeply fissured lava.

Naomi Rumball also travelled with the Cameroon team to study the use of local plants in the Limbe area and acquire material for Kew's Economic Botany Collections. With assistance from Joseph Nkafel and Limbe education staff, Naomi also compiled a reference collection of over 30 minor forest products (mainly spices and stimulants) from local markets, for use by the Limbe Botanic Garden Education Section with duplicates for Kew. Limbe Gardens are actively involved in encouraging the sustainable harvesting of forest products as these form an important part of the subsistence economy. Artefacts collected in Cameroon are on display in the Victoria Gate Visitor Centre.

Ethiopia

FROM 23 September- 13 December 1995, Sally Bidgood undertook joint fieldwork in Ethiopia with staff from The National Herbarium, Addis Ababa, and The Botanical Museum, Copenhagen. Collections were made in NW Ethiopia, which has long been inaccessible due to civil war, and in the remote southwest, where there is a rich but poorly-known flora. A total of 765 specimens was collected and within those named so far are several new records for the country, one species new to science, and a recollection of Satanocrater fellatensis(Acanthaceae) that was known only from the original 150 year-old collection.

The millenium seedbank Basket made from Cyperus involucratus for storing 'injera' (bread made from Eragrostis tef). This was one of 46 Ethiopian artefacts collected by Sally Bidgood for Kew's Economic Botany Collections, depicting aspects of rural life.

Pakistan

The millenium seedbank A TEAM from Kew, the Pakistan National Agricultural Research Council and the Himalayan Jungle Project mounted a seed collecting expedition into northern Pakistan from 15 August to 19 September 1995. This area of western Himalaya is recognised as a region of high floral endemism by IUCN and somes pecies are under significant threat. Kew's living collections are under-represented by natural source material from the region so the collections and field research were required toimprove Kew's ex situ representation of the flora and to complement Pakistan's own research and conservation work. Some 200 seed collections were made and these are now being germinated; seed samples have also been conserved in the Kew Seed Bank. Some of the plants will be displayed in the Irano-Turanian woodland being developed at Wakehurst Place and the collections made of Betula utilis will extend the genetic representa-tion of the National Collection of Betula, also at Wakehurst. All collections are covered by Memoranda of Understanding and discussions are underway on possible ways in which assistance could be given to conservation and sustained development in the area. The expedition in Pakistan was generously sponsored by Mr and Mrs Hugh Stevenson.

Papua New Guinea

BILL BAKER spent seven weeks collecting rattans and other palms in Papua New Guinea, accompanied by Tim Utteridge(University of Hong Kong), as part of a European Union funded rattan project. They found a large number of palm species and made many exciting collections, some of which may prove to be new taxa. New Guinea's palms are poorly known and extensive fieldwork is required before an accurate account of the family can be written for the island.
