In Kenya, we have almost fifty species of Aloe, including three exceedingly poisonous species. Many people have heard of Aloe vera, the so-called wonder plant, and mistakenly call all aloes Aloe vera.

This has caused not just misunderstandings but has had serious consequences. Applying the wrong Aloe on a wound or eating the wrong Aloe can have fatal consequences.

There are three poisonous Aloe species – Aloe ballyi, Aloe elata and Aloe ruspoliana. These species have leaf sap that gives off a strong ratty odour. Fortunately the first two species are relatively rare and not widespread but it is important to know your aloes before attempting to use them medicinally.

Following a presidential ban on the collection of wild-growing aloes, commercial harvesting of aloe sap has taken its place. There is the danger that due to lack of knowledge, this sap could actually be sourced from poisonous aloes.

It’s true that the leaves of several species of Aloe are used medicinally. And the roots of Aloe volkensii, for example, in combination with other plants, are a significant ingredient for many local brews. But beware! One of our missions in Succulenta East Africa is to raise public awareness that there are dangers out there and that not all aloes have medicinal properties!

Not all Aloes are Aloe Vera!

The plants called Aloe include many different species. Most of them have succulent, spiky leaves and colourful flowers. You can see several Aloes on the grounds of the National Museums of Kenya. There is a very famous Aloe called Aloe vera. It does not grow wild in Kenya, but it is planted and used medicinally. The Aloes that we see in the countryside and on safari are not Aloe vera. They belong to different species of Aloe. Sue Allan tells you more about them … 

The National Museums of Kenya (NMK) and a US university are working together to develop technology that will help track amphibians with a view to protecting them. The project targets amphibian species (frogs, toads, newts and salamanders) listed by the International Union for Conservation of Nature (IUCN) as endangered.

Researchers have expressed concern over the rapid decline of frog population in Kenya and Africa in general, citing disease and destruction of natural habitats have been cited as major threats. The situation has been further compounded by lack of information on the species. Data from IUCN shows 1,800 species of amphibians across the world face extinction.

Human activity such as logging and agricultural expansion, climate change and alien species invasion have been blamed for the decline of frog population in Kenya. Poor waste management leading to pollution of water bodies, home to amphibians, has also been contributed to this population.

The first major goal of the project will be to collate information about amphibians in Kenya. This information will be built from existing records. A digital inventory will then be created and updated from time to time.

Using cutting-edge technology to detect the presence of species in the environment, researchers hope to come up with a better documentation method that will enhance the protection of amphibians that live in the soil, water and any other habitats.

Four critically endangered vulture species  found in Africa are set to get a new hope for survival from a 12-year multi-species coordinated action plan set for tabling at a United Nations (UN) summit this month. The critically endangered White-backed, White-headed, Hooded, and Rüppell’s vultures are among 15 vulture species from 128 countries set to get collaborative international protection under the Multi-Species Action Plan to Conserve African-Eurasian Vultures (MsAP).

The International Union for Conservation of Nature (IUCN) Red List of species threatened with extinction has listed a majority of these vulture species as critically endangered, indicating a very high risk of extinction in the wild. Three endangered vulture species — the Cape, Lappet-faced and Egyptian vultures; and two near threatened — the Bearded and Cinereous vultures, found in Africa, are included in the action plan. The plan also covers the Red-headed, White -rumped, Long-billed and Slender-billed vultures, all critically endangered and mostly found in Asia.

Vultures are considered nature’s garbage disposers, as they feed on the carcasses of dead animals that are often infected with diseases such as anthrax, cholera, botulinum toxin and rabies that would be lethal to other scavengers. They therefore play a critical role in maintaining healthy ecosystems. Despite their vital role in nature, vultures are often portrayed as greedy and unprincipled in popular culture. In the field, they are under extreme pressure from a range of human activities. Drastic and widespread population declines in recent years in Africa and Asia have seen some vulture species sliding towards extinction.

In Africa, poisoning is the leading cause of vulture deaths. These deaths occur when people try to kill mammalian predators of livestock (and in some areas feral dogs), with poison-laced carcasses or baits, accidentally attracting vultures. Elephant and rhino poachers also poison vultures in an attempt to mask their tracks, which would otherwise be revealed by the birds circling overhead. The strategic action plan seeks to address threats facing vultures through promoting concerted and collaborative international conservation actions. Among the objectives of the Vulture MsAP are to:

• Rapidly halt current population declines in all species covered by the Vulture MsAP;
• Reverse recent downwards population trends to bring the conservation status of each species back to a favourable level; and,
• Provide conservation management guidelines applicable to all Range States covered by the Vulture MsAP.

The Vulture MsAP will be tabled at the 12th session of the Conference of the Parties to the Convention  on the Conservation of Migratory Species of Wild Animals (CMS COP12) slated for 23rd to 28th October in the Philippines capital Manila. Representatives from more than 120 countries will be in attendance.

The use of poisons to kill wildlife in Africa has rapidly accelerated over the past decade, and is having a devastating

effect on the populations of many species. In Kenya there has been as escalation in the use of poisons due to various reasons. Highly toxic     pesticides are used to lions and hyenas in retaliation for damage to livestock. Monkeys and elephants are targeted due to conflicts with farmers. Very concerning is the use of poisons to harvest animals as a food source where fish and waterbirds are frequent targets. Due to the indiscriminate nature of poisons, there are almost always unintentional consequences that affect a broad range of terrestrial and aquatic species, including humans. Vultures are the most severely afflicted, as they are typically the first to arrive at a poisoned carcass, and they feed in large numbers. There are also serious issues involving contamination of lakes, rivers, and waterholes whenever toxic pesticides are sprinkled into these water sources to harvest fish or other aquatic species.

The Peregrine Fund has been collecting data on wildlife poisoning since 2005 and has now joined forces with the Endangered Wildlife Trust (EWT) based in South Africa to assess the scope and impact of this critical threat to vultures and other wildlife species across Africa. In partnership with the Vulture Specialist Group of the IUCN Species Survival Commission and The Gadfly Project, the Peregrine Fund has collated all historical and current incidents of wildlife poisoning into the African Wildlife Poisoning Database or AWPD, www.africanwildlifepoisoning.org

So far, the database contains records of 272 poisoning incidents that have killed over 8,000 animals of 40 different species, from 15 countries. Although records of poisoning date back to 1961, in the past decade there has been a sharp escalation in poisoning incidents, with most of the deaths occurring during this time. Aside from vultures, species affected range from large carnivores, such as lions, leopards, and hyenas, to elephants, impalas, cranes, and storks. However, by far the most deaths are of vultures, comprising ten different species, including two species that migrate to Africa from Europe. Poisoning is the most significant threat to vultures in Africa and Eurasia and, over the last 30 years, has contributed to declines in excess of 80% in some African species. Currently, the IUC N Red List of Threatened Species lists four species of African vulture as Critically Endangered and three species as Endangered.

The AWPD is designed to facilitate simple, effective capture of relevant data, either by using a mobile device at a wildlife poisoning incident, or by inputting data via the website. Users can access basic information on poisoning incidents and mortalities, and view these on a map of Africa. The AWPD will contribute to gathering better information on poisoning incidents, as well as on the drivers of wildlife poisoning
