For Insect Week we’re shining the spotlight on one of our finest Fantastic Freshwater insects.

Meet the rock threadtail

Perched on stones set in the rocky streams of eastern Zimbabwe is one of our most delicate fantastic freshwater species. First discovered in 2013 in Chimanimani National Park, the rock threadtail (Elattoneura lapidaria) was described in 2015, then listed as critically endangered in 2017.

This damselfly is found at whopping elevations, as high as 1500-1600m above sea level in the Chimanimani Mountains. Endemic to Eastern Zimbabwe, the species is only found in the Bundi Plain and Bundi Valley.

Damsel(fly) in distress

The rock threadtail is one of the 50 landmark species at high risk of extinction identified in SHOAL’s Fantastic Freshwater* report. Published on 19th May 2022 (International Day for Biodiversity), Fantastic Freshwater highlights the diversity and beauty of freshwater species and the immense threats they face to their survival.

Like many of our Fantastic Freshwater species, threats to the rock threadtail are largely a result of degradation of their habitat – in this instance as a result of particularly prolific illegal gold mining activity.

Despite Chimanimani National Park being a protected area, more and more people are travelling to eastern Zimbabwe hoping to find gold, including the park rangers. The activity has caused great harm to the natural water sources and biodiversity of the region and poses a major threat to the future of the rock threadtail.

Panning for solutions

At this stage further research of the habitat in Chimanimani National Park is needed, in order to address activities that are threatening the rock threadtail and develop a plan for meaningful conservation action.

We’re giving some love to our Fantastic Freshwater plants this International Plant Appreciation Day.

Just 5% of all plants live in freshwaters, but they are absolutely vital to these ecosystems – and the species that call them home – surviving and thriving.

Plants oxygenate water, reduce flood risk, support nutrient cycling, and remove pollutants. They’re really doing some heavy lifting to keep our freshwater fresh!

Meet malabar rotala

With its characteristic small pink and red flowers, malabar rotala (Rotala malabarica) is a beautiful plant native to the Kannur District in Kerala, India, from where it was described in 1990.

The species has in fact only been recorded in a total of 22 ponds, with more than half of the known population in a single pond. One pond with half the population!

The Western Ghats – home to the Denison’s barb – runs along the coast of western India. The range of mountains support a very wide range of wetland-dependent plants, and represent one of the global centres of diversity of aquatic and wetland plants.

Now the bad news

Malabar rotala is one of the 50 landmark species at high risk of extinction identified in SHOAL’s Fantastic Freshwater* report. Published on 19th May 2022 (International Day for Biodiversity), Fantastic Freshwater highlights the diversity and beauty of freshwater species and the immense threats they face to their survival.

Wetlands are very sensitive ecosystems and rely on specific environmental conditions; any disruption of these specific conditions can pose serious threats to freshwater flora. Threats to malabar rotala include:

  • Leakage of waste and habitat destruction from mining
  • Quarrying of the laterite bedrock which hold the seasonal pools where it occurs

Turning the tide

Unfortunately there are currently no conservation actions in place to protect and restore the malabar rotala.

As with other freshwater plants, more research is needed to  increase our knowledge of its ecology, threats, habitat and population trends, so that effective conservation actions can be taken.

One year after announcing them as our newest partner, it’s time to check in with PROGRES, a conservation NGO in Sulawesi, Indonesia.

One year after announcing them as our newest partner, it’s time to check in with PROGRES (Sulawesi Regional Ecological Conservation Initiative), a conservation NGO in Sulawesi, Indonesia.

A little backstory

Led by two Sulawesi native women, Sheherazade and Asnim A. Lanusi, PROGRES fuses science with the power of locally-led conservation action to ensure the success and sustainability of their work.

Working with the Asian Species Action Partnership in the Lake Poso region of Sulawesi, considered to be one of the most important ecosystems for freshwater fish conservation in the world. PROGRES’ Fish Programme is focussed on the search for three Critically Endangered fish that are endemic to the lake.

  • Duck-billed buntingi (Adrianichthys kruyti)
  • Rosen’s buntingi (A. roseni)
  • Poso bungu (Mugilogobius amadi)

The sharp decline of each species has been thought to be a result of tectonic activities in the region in 1983, alongside the damage by invasive species through parasites and diseases (Parenti and Soeroto 2004).

Meet Chilo and Felix

A key part of PROGRES’ work is engaging with young people in the local community to be conservation champions and lead the conservation initiatives.
Chilo and Felix work with PROGRES in Sulawesi and have been integral to the search for the duck-billed buntingi, one of our Top 10 Most Wanted Lost Fishes.

Chilo: “Konservasi adalah memberi kehidupan, kesempatan berwawasan, memberi kesadaran ada yang hampir hilang, untuk itu konservasi harus cepat dilakukan sebelum semuanya terlambat.”

Chilo: “Conservation is about nurturing life, an opportunity to learn, raising awareness that something is almost gone, for that conservation must be done quickly before it’s all too late.”

Felix: “Konservasi bagi saya adalah merawat lingkungan hari ini untuk kehidupan besok yang lebih baik.”

Felix: “Conservation for me is caring for today’s nature for a better life tomorrow.”

PROGRES are working in collaboration with fishermen around Lake Poso too, surveying 21 villages and one city to understand local livelihood, the dependence on Lake Poso and the importance of the fishes to local communities beyond their economic value.

Three fishermen, Om Pedi, Papa Jems, and Ngkai Iki, actively joined PROGRES’ survey activity, alongside 11 local youth. These fishermen and young people have become messengers explaining what the program was about to other parts of the communities.

What have PROGRES been up to?

Extensive surveys have been conducted every month to look for the ASAP targeted fish species. In total, 18 surveys were conducted in water areas in front of Bancea, Leboni, and mainly Peura, Dulumai, and Tolambo villages.

Let’s talk about the Diadem lady’s mantle

Checking out one of our (literally) flashier Fantastic Freshwater species.

We’re giving some love to our Fantastic Freshwater plants this International Plant Appreciation Day. Plants are vital components of freshwater systems, oxygenating the water reducing flood risk, supporting nutrient cycling, and removing pollutants. They’re really doing some heavy lifting to keep our freshwater fresh!

Meet the Diadem lady’s mantle

The Diadem lady’s mantle (Alchemilla diademata) is a beautiful plant is native to Lebanon. Its regal name is inspired by the way its leaves form a crown-like shape around the stem.

The Diadem lady’s mantle has an interesting history of use in traditional medicine. Used for centuries as a natural remedy for a variety of ailments, from digestive issues to menstrual problems, some even believe the plant is anti-aging.

The plant has recognised antimicrobial properties, and is used as an effective medicine against Staphylococcus which can be associated with skin infections and food poisoning. It also appears to work as a significant repellant of silverleaf whitefly, an agricultural pest species.

Arise, threats

The Diadem lady’s mantle is one of the 50 landmark species at high risk of extinction identified in SHOAL’s Fantastic Freshwater* report. Published on 19th May 2022 (International Day for Biodiversity), Fantastic Freshwater highlights the diversity and beauty of freshwater species and the immense threats they face to their survival.

Threats to the species are closely connected to its habitat preferences, with threats including:

  • Sandstone mining
  • Overgrazing by sheep, especially during the dry season

The Eastern Mediterranean Freshwater Assessment was concluded in 2014 and represents the first major assessment of the status of and threats to freshwater biodiversity, including plants, in the region. Although large parts of this region are semi-arid and arid in nature, it supports a diverse set of freshwater species and habitats which provide a wide variety of ecosystem services to the human population, including water, food, and income.

Heavy is the head

Unfortunately there are currently no conservation actions in place to protect and restore the Diadem lady’s mantle.

In an ideal world, the actions in place would include national regulations and ex situ conservation efforts.

Meet the Kumejima firefly

In springtime, the nights in Kumejima are brought to life with the bright green glow of native fireflies. Discovered in 1993, the Kumejima firefly (Luciola owadai) is one of our (literally) flashier Fantastic Freshwater species.

With an adult life span of less than two weeks, impactful flirtation is critical for the nocturnal species. Males will travel in groups and emit their light in one burst to attract a mate. This display is as enchanting as it is effective, with females going on to lay an impressive 300-500 eggs, which emit a faint yellow glow.

Shine a light on the threats

The Kumejima firefly is one of the 50 landmark species at high risk of extinction identified in SHOAL’s Fantastic Freshwater* report. Published on 19th May 2022 (International Day for Biodiversity), Fantastic Freshwater highlights the diversity and beauty of freshwater species and the immense threats they face to their survival.

Found along the streams of Kume Island, the Kumejima firefly makes its home where the riverside vegetation is dense and covered by evergreen broadleaf trees. Like many of our Fantastic Freshwater species, threats to the Kumejima firefly are largely a result of degradation of their habitat.

The species is being threatened by:

  • The streams where the species lives have experienced decreased stream flow and deterioration of riverside vegetation due to water source development
  • A change in cultivated land from rice farming to sugar cane fields has caused the runoff of large amounts of red clay
  • Environmental changes causing a decrease in their prey, freshwater snails

Light at the end of the tunnel

Despite not yet being assessed for the IUCN Red List, the Kumejima firefly is on Japan National Red List (2016) with the Japan Ministry of the Environment describing the species as Critically Endangered.

Local action to conserve the species is led by the Kumejima Firefly Museum, established in 2000. The museum staff work alongside local volunteers to address the conservation needs of the species by recovering and maintaining the stream and biotope environments nearby.
