The Zaire Gorilla Conservation Project was launched in 1984 after the 1981 census of mountain gorillas in the Virungas showed how the Mountain Gorilla Project in Rwanda, in which FFPS was closely involved, had helped to swell numbers. Over the past few years the Zaire project has made encouraging progress. The 1986 census counted the highest number of gorillas since the early 1970s and some of that increase can be attributed to improved protection in Zaire. In addition, the park is benefiting from income from tourists visiting habituated gorilla groups. The project continues to extend, taking in eastern lowland gorillas and chimpanzees, as well as developing an overall education programme for the region around the park.

Concern about the effects of feral goats on Aldabra atoll—a UNESCO World Heritage Site—led to a search for solutions. The search highlighted the inaccessibility of information on feral goat eradication campaigns. As a result the International Council for Bird Preservation and the FFPS, through its Oryx 100% Fund, commissioned a report to bring together and assess known techniques and potential strategies and to consider their implications for conservation practice. This article is a shortened version of that report.

In 1985 Taiwan responded to widespread concern about its role in the international rhinoceros trade by banning imports and exports of all rhinoceros products. It is disheartening and alarming that, three years later, the trade still thrives and little has been done to enforce the new law. The authors describe the situation in Taiwan, discuss the implications for the world's last rhinoceros populations and recommend what action should be taken.

Evidence from a survey conducted by the European Continental Section of the International Council for Bird Preservation (ICBP-ECS) suggests that birds have not served as such good early warning indicators of ecological damage from acid precipitation as they have for damage from organochlorine pesticide use. Only a few highly specialized species have been badly affected, and then long after the impact was observed in other organisms. Some birds have even benefited from the superabundance of dead and decaying standing timber.

The Souss Valley in Morocco still has remnants of forest dominated by the argan tree, which is endemic to the Atlantic coast of north-west Africa. The tree is valued for its edible oil and its timber and the argan forest ecosystem is rich in species. The forest has been exploited sustainably by man tor thousands of years, but modern developments have destroyed or damaged much of it, especiallyin the lowlands. The author, who worked in the region for three years, is alarmed at the rapidly increasing destruction. He makes a plea for effective protection of the remaining argan torest and for a plan for its sustainable exploitation.

In 1986 the FFPS contributed £750 from its Oryx 100% Fund towards a study of riparian forest in Somalia. Only small fragments remain. The local and national importance of these forests demands that urgent action is taken to conserve them, as the author explains.

The Peruvian diving petrel Pelecanoides garnotii is endemic to the Peruvian or Humboldt Current. Descriptions of past colonies suggest that the species was once abundant in Peru, but harvesting guano on its nesting islands and killing the birds for their meat caused a drastic decline in the population. Fishing activities and direct exploitation threaten the only two remaining breeding colonies in Peru. There are an estimated 4000 breeding individuals left, but unless they are protected the species will continue to decline.
