History

This collection is comprised of about 1,300 photographic slides that Shuzo Ito (also spelt as Syuzo Itow) took in 16 field investigations of plants and vegetation in the Galapagos archipelago over 38 years since 1964. The years and sites of the fieldwork are given below.

January to February 1964:
He participated in the Galapagos International Scientific Project (GISP) jointly organized by the University of California at Berkeley and California Academy of Science and conducted plant ecological investigations on Santa Cruz, Santa Fe, Floreana, Espanola, and San Cristobal.
January to June 1970:

He stayed at the Charles Darwin Research Station in the Galapagos archipelago as a long-term visiting research associate of the Ministry of Science and Education, Japan, and carried out field work in the following 19 islands (a volcano is considered an island with regards to Isabela) from the east to the west: San Cristobal, Espanola, Floreana, Champion, Genovesa, Santa Fe, Plaza, Baltra, Santa Cruz, Eden, Daphne, Bartolome, Santiago, Beagle, Rabida, Pinzon, Sierra Negra Volcano and Alcedo Volcano of Isabela, and Fernandina.

January to April 1978:
To supplement the investigations made in 1970, he visited the following islands (islands visited in 1970 are omitted): Seymour, Guy Hawks, Sombrero Chino, Marchena, Pinta, and Darwin Volcano and Azul Volcano of Isabela.

In successive surveys after 1981, the same sites and the other districts of the same islands were visited. Coamano was the only island newly surveyed in 1991. The years and months of the fieldwork are as follows:
August 1981, August 1986, April 1987, January to February 1991, March to April 1995, August 1995, August to September 1998, August 1999, December 1999, February 2001, April 2001, and March to April 2002.

In the above-mentioned trips, he visited a total of 27 islands (a volcano is considered as an island with regard to Isabela) and published the survey routes on each island visited between 1964 and 1995 in his paper: S. Itow (1997), List of Plant Specimens Collected in the Galapagos Islands, Ecuador. Bulletin of the Faculty of Liberal Arts, Nagasaki University, (Natural Science), Vol. 38, No. 1, 53-144, Fig. 1-10.
He took over 3,000 color photograph slides in the field trips and selected about 1,300 of them to include in this collection. They may be searched for by keyword, year of photographing, and site (island) of photographing. In addition, sets of photographs are presented on 14 themes.

Identification of plant species

The plant collection was completed through investigations conducted in 1964, 1970, and 1978.

Species collected in 1964 and 1970 were either identified by the late professor Dr. Ira L. Wiggins at Stanford University or checked against specimens kept by the professor for identification. These specimens closely in nearly all cases matched the slides. Photographs taken thereafter were also checked likewise to identify the species. Concerning some plant photographs, Ms. Heinke Jaeger, M.Sc. (Technische Universitat Berlin), a former researcher at Charles Darwin Research Station, provided advice.
