IUCN (The World Conservation Union) published its first Action Plan more than a decade ago (Oates 1986). Many taxon-specific Specialist Groups working under the auspices of the IUCN Species Survival Commission (SSC) have since produced such documents, some of which are now in their second editions (e.g. Reeves and Leatherwood 1994). As we know only too well ourselves, Action Plans take a great deal of time and effort to compile, but what evidence is there to show that they are effective in achieving their prime objective of increasing the amount and quality of work that gets done to save threatened species from extinction?

The Crested Argus Rheinardia ocellata nigrescens is endemic to Peninsular Malaysia and is threatened with extinction. It is known from elevations above 600 m and is limited to a few mountain ranges in Peninsular Malaysia. First described in 1902, this subspecies was only known from Gunung Tahan and Gunung Rabung for many years. Recent surveys have added several new sites: Gunung Mandi Angin and Gunung Gagau, Gunung Penumpu and Camp Kor. All known sites are in Taman Negara National Park.

The Green Peafowl has undergone a substantial decline throughout East Asia since the turn of the century and is now reported only from a few widely scattered localities in several countries. Its plight was highlighted in the IUCN Pheasant Action Plan where it was one of the highest priorities for conservation action. Recent surveys have clarified its status and distribution in at least part of several range countries and there is patchy information from elsewhere in its range. The current knowledge of the species was reviewed at a workshop in Malaysia in autumn 1997 at which representatives from most key countries were present. The species is extinct in Peninsular Malaysia, and almost lost from Bangladesh and north-east India. There is one large population remaining in Thailand and the species is thought to be in danger of extinction in Laos. China and Indonesia hold mostly small and scattered populations although the latter does contain two large protected populations. The status in Myanmar and Cambodia is unknown, although the presence of large tracts of apparently suitable habitat in eastern Cambodia suggest that this area may hold the largest populations of the species. Conservation recommendations fall into four categories: a strategic review, assessing status and understanding ecological requirements, investigating the human-Green Peafowl relationship and considering the possibility of reintroducing the species where appropriate.

The critically endangered Sichuan Hill-partridge Arborophila rufipectus occupies a restricted range in south-central China. Field surveys within this range were undertaken using line transects in 1996 and 1997. Calling males were recorded from nine subtropical forest tracts within an area totalling 1,793 km2 and consisting of primary, natural secondary and replanted broadleaf forest between 1,100 and 2,235 m elevation. The only sightings obtained were in primary forest. The mean density of calling males estimated from data collected during transect surveys was 0.48 ± 0.06 and 0.24 ± 0.16 calling birds km−2 in 1996 and 1997 respectively. There was no difference in density estimates for calling males between primary forest and secondary/replanted broadleaf forest. The principal threat to the continued survival of the species is clear-felling of primary forest, but clear-felled areas are often replanted with native broadleaf trees and records of Sichuan Hill-partridge calls in such plantations offers hope for its future survival. Forest management should be modified to make forestry practices more sympathetic to the conservation of the Sichuan Hill-partridge.

Call counts of Satyr Tragopan Tragopan satyra were conducted in the Singhalila National Park, Darjeeling, India, for three years (1995–1997). Twenty-eight groups of calling birds were recorded in 1995, 19 in 1996 and 24 in 1997 with mean density estimates (groups/km2) of 6.19/km2, 4.52/km2 and 5.46/km2 respectively. During the three years, the number of calling groups varied only on one trail. Birds called early (04h45–05h00) and the calling frequency varied from 33% to 88%. Calling peaked in April and there were significant differences in the number of groups calling in April and May in 1995 and 1996. Adverse weather conditions and wind affected calling and the audibility of calls. During spring, the Satyr Tragopan was found to be associated with both open and closed habitats. The main possible threats to this species were grazing and tree lopping. Despite some shortcomings this survey method appears to be most suitable for monitoring Satyr Tragopan.

We distributed questionnaires and conducted interviews between July and November 1996 to develop a better understanding of the status and distribution of Bornean Peacock-pheasant Polyplectron schleiermacheri in Central Kalimantan, Indonesia. We found that many people were familiar with the species, that it is apparently widely distributed but rare in lowland forest, and that populations may be declining. We received reports of recent sightings of the pheasant at 23 locations in 9 survey areas. The primary threats to Bornean Peacock-pheasants are habitat loss within logging concessions and hunting. Recommendations for future conservation action include increasing the representation of lowland rainforest in Kalimantan's protected area system, specifically the proposed extension of Bukit Raya National Park, and control of hunting within logging concessions.

Domestic chickens were derived from the wild Red Junglefowl Gallus gallus. A survey of 745 museum specimens of Red Junglefowl suggests that most wild populations have been contaminated genetically by introgression of genes from domestic or feral chickens. A male eclipse plumage, which appears to be an indicator of pure wild genotypes, was found in populations in the western and central portions of the species's range, but not in the easternmost populations. Eclipse plumages probably disappeared from extreme south-eastern Asia and the Philippines prior to the advent of intensive scientific collecting (about 1860) and have not been observed in Malaysia and neighbouring countries since the 1920S. Populations exhibiting eclipse plumages were found in north-eastern India as late as the 1960s, but the dense human populations there make their continuing genetic integrity uncertain. These data suggest that surveys of wild and captive populations should be undertaken to assess the genetic integrity of this species. A re-evaluation of the conservation status of Red Junglefowl might then follow.

An historical study shows that the present day ex situ population of Edwards's Pheasant Lophura edwardsi, now numbering over 1,000 living specimens, originated in the 1920s from at least six different sources and c. 30 potential founders, including more males than females. Partial sequences, 820 nucleotides long, of the mitochondrial DNA (mtDNA) control-region were obtained in representatives of about half of 21 captive-reared bloodlines, identified from data in the revised International Studbook. All captive-reared birds had identical sequences. Sequences of mtDNA obtained from museum skins and samples of birds collected in the wild were slightly different from that representing the captivereared birds. The lack of mtDNA variability in the captive stock is probably due to the small number of founding females and genetic drift during c. 30 generations of captive breeding. Estimation of true extent of mtDNA sequence variability in historical and living wild Edwards's Pheasants awaits the procurement and analysis of more specimens. At least one bloodline of captive Edwards's Pheasant is polluted with exogenous genes resulting from past hybridization with Swinhoe's Pheasant L. sivinhoii. Edwards's Pheasant is more closely related to Vietnamese Pheasant L. hatinhensis and Imperial Pheasant L. imperialis than to several other taxa regarded as full species in the genus Lophura. However it is not yet possible to determine the extent of their evolutionary divergence and of their proper taxonomic rank. The initial results of this genetic research suggest that there should be efforts to (1) expand field sampling and genetic analyses of wild populations of Lophura species, (2) purge the captive stock of Edwards' Pheasant of all hybrids, (3) apply microsatellite analyses to estimate the level of genetic diversity in nuclear DNA.

The Hainan Hill-partridge Arborophila ardens is endemic to the island of Hainan, which lies off the south coast of China. Distinct subspecies of the Silver Pheasant Lophura nyethemera xvhiteheadi and Grey Peacock-pheasant Polyplectron bicalcaratum katsumatae are also endemic to the island. All three taxa are considered endangered and are very poorly known in the wild. Surveys of remaining patches of forest were undertaken between 1987 and 1994 during which local people were interviewed and some forest areas were visited. The hill-partridge was confirmed from three blocks of forest and reported from a further four. The Silver Pheasant was found in six areas of forest and probably occurs in all remaining patches of well-developed secondary and primary forest. The Grey Peacock-pheasant was recorded in five forests and reported from a further four. The hill-partridge was more restricted in its habitat use than the other two species, the latter using well-developed secondary forest in addition to primary forests. Provisional density estimates made at Ba Wang Ling National Nature Reserve were 6–8 Hainan Hill-partridges/km2, 7.5 Silver Pheasants/km2 and 3.75 Grey Peacock-pheasants/km2.
