LOGGING AND LOG TRANSPORT IN TROPICAL HIGH FOREST
Information concerning logging and transport methods and techniques and costs in developing countries is scarce, especially where the tropical high forest is concerned.
Logging and Log Transport in Tropical High Forest, a new manual prepared by the FAO Forestry Department's Logging and Transport Branch, focuses attention on analytical approaches required to quantify output and cost data for these activities. It examines the influence of physical and economic conditions and gives production and cost data where available for the most commonly used logging methods.
Logging and Log Transport in Tropical High Forest (A manual on production and costs), FAO Forestry Development Paper No. 18, FAO, Rome, 1974; 90 pages, English, French and Spanish editions; price US$3.00 or £1.20.
SEED FROM CANADA
A List of Seed in the Canadian Forestry Service Seed Bank, by B.S.P. Wang and B.D. Haddon, was issued in June 1974. This report, in French and English, may be obtained from the Petawawa Forest Experimental Station, Chalk River, Ontario. It is also identified as Information Report PS-X-53. In 1973, the station shipped more than 300 seed lots in response to requests from within Canada and from 12 other countries.
STORING TREE SEED
Tree-Seed Storage by B.S.P. Wang, is a 30-page report in English, with a résumé in French, issued by the Canadian Forestry Service.
Dr. Wang, of the Petawawa Forest Experimental Station, Chalk River, Ontario, reviews seed characteristics of trees, storage principles and major factors affecting seed storage. He summarizes the times of cone and seed maturity and the storage requirements of native Canadian tree seeds and outlines further research needed to prolong the safe storage of large hardwood seed. The report contains two tables, one showing "Frequency of seed years of native tree species" (27 species of conifers and 37 hardwood species) and another which is a "Summary of specific conditions for safe storage of tree seeds."
FROM EAST AFRICA'S HERBARIUM
Upland Kenya Wild Flowers by A.D.Q. Agnew, is the latest major work on the flora of tropical east Africa. It covers the whole herbaceous vascular plant flora-except the grasses and sedges - of Kenya above 1000 metres, a total of no less than 2950 species, of which 943 are illustrated by line drawings.
The work includes several contributions from specialists, most of whom are associated with or on the staff of the East African Herbarium, a division of the East African Agriculture and Forestry Research Organization. Of note is an account of the ferns by R.B. Faden, the first of its kind, and Dr. Agnew's account of the Compositae, of which the most recent description until now (and without illustrations) was written in 1877.
The book is published by the East African Agriculture and Forestry Research Organization, P.O. Box 30148, Nairobi, Kenya.
