Mammals

Giant Eland_Tragelaphus derbianus

Giant Eland (Tragelaphus derbianus) is the largest antelope species, with highly distinctive tightly spiralled “V” shaped horns. This west and central African antelope moved from Least Concern (LC) to Vulnerable (VU) in 2017. In 1999 an estimated 15,000-20,000 Giant Eland existed. However, political instability and civil conflict in parts of its range over the last 10-15 years have greatly disrupted protection and management in Protected Areas (PAs). In addition, poaching (for bushmeat) and encroachment by farmers and livestock owners into protected areas have increased. Overall the global population is now estimated to be no more than 12,000-14,000 and is declining. Photo © Brent Huffman / UltimateUngulate

Eudorcas tilonura_Heuglin's Gazelle

Heuglin's Gazelle (Eudorcas tilonura) ranges from east of the River Nile between southern Sudan, northern Ethiopia and western Eritrea. In 2017 the species moved from Vulnerable to Endangered (EN) as the small global population of this species declined by at least 20% since its previous assessment (in 2008). In 1999, the population was estimated as 3,500-4,000, but by 2016 this had declined to no more than 2,500-3,500. Poaching, competition with domestic livestock, habitat degradation, and ineffective protection in most of its range are responsible for the continuing decline of this gazelle.

Christmas Island Pipistrelle_Pipistrellus murrayi

The Christmas Island Pipistrelle (Pipistrellus murrayi) was declared Extinct (EX) on The IUCN Red List in 2017, after extensive surveys since its last record in August 2009 failed to find the species again. Christmas Island (Australia) is in the eastern Indian Ocean, and this was the only Pipistrelle bat species on the island. Ultrasonic bat detectors were therefore very effective at finding individuals, as it was readily recorded and could not be confused with other species. So there is a high degree of certainty that this species is now Extinct. The reasons for the decline and extinction of this bat are unclear. Habitat loss may have caused some declines in the past, but this does not fully explain the complete loss of this species. Predation and disturbance by invasive species, habitat change and reduced invertebrate prey due to introduced Yellow Crazy Ant (Anoplolepis gracilipes), and possibly an unknown disease may all have contributed to its demise.

Rodrigues Flying Fox_Pteropus rodricensis

Thanks to ongoing conservation actions, including a successful captive breeding programme involving 46 zoos around the world, restoration of natural habitat, watershed protection, and awareness raising and education programmes, the status of the Rodrigues Flying Fox (Pteropus rodricensis) improved enough to move the species into a less threatened category in 2017; it moved from Critically Endangered to Endangered (EN). Its population has increased from just 4,000 in 2003 to an estimated 20,000 individuals in 2016. While this move to a less threatened category is good news, the future survival of this species very much depends on continued conservation efforts and future climate change scenarios, as severe tropical cyclones can cause mortalities of over 50% for this species.

Nancy Ma’s Night Monkey_Aotus nancymaae

Habitat loss through conversion of forests for agriculture, and capture of wild animals for biomedical research and the pet trade have caused a population decline of at least 30% over the last 25 years for the charismatic Nancy Ma’s Night Monkey (Aotus nancymaae). This decline, which is ongoing, resulted in the species moving from Least Concern to Vulnerable (VU) on The IUCN Red List in 2017. Illegal trade of night monkeys for malaria research is of particular concern for this species, as it is drastically affecting wild populations in the tri-border area of Brazil, Colombia and Peru.

Reptiles

Southern Even-fingered Gecko_Alsophylax laevis

Serious population declines resulted in the Southern Even-fingered Gecko (Alsophylax laevis) being added to The IUCN Red List as Critically Endangered (CR) in 2017. This species typically occurs in bare, flat clay areas that are almost free from vegetation in the sand desert zone (takyrs) of Uzbekistan and Turkmenistan. It is experiencing significant habitat loss through ploughing and irrigation of takyr habitat for crop cultivation, and the site where the species was first discovered no longer exists, having been inundated by the creation of a dam. More than half of its historical habitat has been lost over the past 20-30 years Photo © Patrick Randall

Amphibians

Gold-spotted Marsupial Frog_ Gastrotheca aureomaculata

In 2017, the Gold-spotted Marsupial Frog (Gastrotheca aureomaculata) entered the threatened categories on The IUCN Red List, moving from Near Threatened to Endangered (EN). The species is known from only a few localities in south-central Colombia. It has not been recorded since at least the 1960s, but the region has not yet been intensively explored. Habitat destruction through timber extraction and spread of agriculture (including cultivation of illegal crops), and water pollution pose the most serious threats to this arboreal frog.

Invertebrates

Intermediate Royal Pygmy Grasshopper_Andriana intermedia

Madagascar is home to the Intermediate Royal Pygmy Grasshopper (Andriana intermedia), which entered The IUCN Red List as Vulnerable (VU) in 2017. This long-winged species inhabits moist lowland and moist montane tropical forests and its population is believed to be declining due to ongoing loss of forest habitat, as logging and wood harvesting is ongoing within its range.

Red-legged Fire-Millipede_Aphistogoniulus corallipes

The Red-legged Fire Millipede (Aphistogoniulus corallipes) is only known from the private reserve of Manantantely, a small fragment of remaining lowland rainforest in southeastern Madagascar. The species entered The IUCN Red List in 2017, assessed as Critically Endangered (CR). Its forest habitat has been heavily exploited in the past and continues to decline due to slash and burn agriculture and timber collection by the local communities. The survival of this millipede entirely depends on the persistence of this forest. Photo © Thomas Wesener

Plants

White Ash_Fraxinus americana

Native to central and eastern United States, the widespread White Ash (Fraxinus americana) is the most common of the native U.S. ash tree species. Nevertheless, the species made its debut on The IUCN Red List as Critically Endangered (CR) in 2017. Its timber is tough, strong and highly resistant to shock making it useful for a wide variety of goods, e.g. from baseball bats and tool handles, to guitars and furniture. Along with all other U.S. ash tree species, White Ash is suffering devastating impacts from the invasive Emerald Ash Borer beetle (Agrilus planipennis), which was introduced into the U.S. in the 1990s, probably through infested shipping pallets or crates from Asia. With no currently known solution to halting the rapid spread of this destructive invasive species, White Ash is expected to undergo a decline of at least 80% over the next 100 years.

Goldenseal_Hydrastis Canadensis

Goldenseal (Hydrastis canadensis) is a well-known North American medicinal plant from the United States and Canada. The species is used as a supplement to treat a range of upper respiratory tract infections, hay fever, and a variety of digestive disorders. This plant’s range and habitat quality have declined significantly, resulting in a population decline of at least 30% over the past 21-27 years. The combined threats of habitat clearance and harvesting of wild plants for domestic and international medicinal plant markets are driving this continuing decline, causing the species to enter The IUCN Red List as Vulnerable (VU) in 2017.

Allium iatrouinum

The Mediterranean species Allium iatrouinum was added to The IUCN Red List as Critically Endangered (CR) in 2017. Currently this plant is known only from Mount Ochi in the southern part of Evvia Island, Greece, and has an estimated global population of around 200-400 mature plants. Although the known population is within a Natura 2000 site, numerous wind parks have been developed in the area, and wind turbines are under construction within its distribution area, which potentially threatens the only known population. Further research is needed to confirm whether this species occurs in a wider area and the impact of wind park development on the known population. Photo © Panayiotis Trigas

Wilmott's Whitebeam_Sorbus wilmottiana

Wilmott's Whitebeam (Sorbus wilmottiana) is endemic to western England, where it is known from both sides of the Avon Gorge in Somerset and Gloucestershire. The species moved from from Critically Endangered (CR) to Endangered (EN) in 2017 after some regeneration in the population over the past twenty years. The population is still very small (97 individuals in 2016, of which 60 were mature trees), and it is currently under threat from a fungus disease and potentially from work on upgrading a nearby railway line, so the species still requires ongoing conservation efforts to secure its future.

Carolina Ash_Fraxinus caroliniana

Carolina Ash (Fraxinus carolinina) entered The IUCN Red List as Endangered (EN) in 2017. This ash tree occurs throughout southeastern USA and on the island of Cuba. It is a fairly widespread species in certain wetland habitats, however, similar to other North American ash species, Carolina Ash has been declining rapidly since the introduction of the invasive Emerald Ash Borer beetle (Agrilus planipennis). This beetle has decimated the populations in North Carolina and is rapidly spreading across the majority of the Carolina Ash tree’s range. It is possible that the southernmost Carolina Ash populations may be too tropical for the beetle to survive, but it is very likely that at least 50% of the range be suitable for Emerald Ash Borer, and those trees will likely be rapidly killed by infestation.
