Newborough Forest in Anglesey is home to seemingly ordinary ponds bustling with wildlife, including dragonflies, lizards, and various insects.
However, these unassuming pools harbor an intriguing creature that, at first description, appears incredibly terrifying.
Possessing 300 teeth, 10 eyes, numerous stomachs, 32 brains, and nine pairs of testicles, these creatures also have a peculiar taste for human blood.
Despite the ominous warnings of “Beware the blood suckers” signs by the ponds, these beings known as medicinal leeches are far less menacing than they sound.
Although they leave behind painless bleeding, they pose no real harm.
The Decline of Leech Habitats:
For decades, Newborough Forest has been one of the few locations in Britain where leeches can be found.
Unfortunately, even this sanctuary is experiencing a reduction in suitable habitats as ponds become silted up and vegetation encroaches upon their surroundings.

Recognizing the need to protect the leeches and other rare species like great crested newts, the EU-funded Sands of LIFE (SoL) project and the Natural Resources Wales land management team have undertaken efforts to re-profile the ponds over the past three years.
These conservation efforts aim to not only safeguard the leeches but also enhance the forest’s biodiversity.
Conservation Efforts to Maximize Biodiversity:
To counter the shrinking habitats, the Sands of LIFE project and the land management team have implemented measures to enlarge the ponds, eliminate invasive species and old conifer stumps, and clear the edges to expose sand.
These actions enable effective management of the areas to promote biodiversity.
Kathryn Hewytt, the SoL project manager, highlights that these initiatives have rescued certain species on the brink of disappearance as the pools filled up.
By creating favorable conditions, the project endeavors to expand and sustain the diverse ecosystem of Newborough Forest.
The Harmless Nature of Leeches:
Contrary to popular belief, leeches are not inclined to target humans who traverse the forest.
Instead, they are more likely to seek out other animals, including pets.

Information boards along the Bike Quest Nature Trail in the forest assure visitors that leeches rarely attach to humans due to their aversion to blood extraction.
The leeches thrive thanks to the presence of horse blood, which enters the ponds when horses drink from them.
The introduction of veterinary flea and worming treatments since the 1970s has been detrimental to leech populations, and conservationists fear that recently treated dogs may undermine their efforts at Newborough Forest.
Preserving Leeches and Preventing Pollution:
The Sands of LIFE project has issued a plea via social media, emphasizing that veterinary flea treatments cause water pollution and harm rare invertebrates such as leeches.
Therefore, dog owners are urged to prevent their pets from playing in the pools on the dunes to avoid undoing the conservation work.
Analysis:
The description of the leeches in the initial paragraph sets a dramatic tone, playing on the reader’s fear and fascination.
However, subsequent paragraphs clarify that these creatures pose no real danger to humans.
This demonstrates the importance of accurate information to dispel misconceptions and encourage conservation efforts.

The mention of the Sands of LIFE project and the Natural Resources Wales land management team highlights the collaborative nature of the conservation work at Newborough Forest.
It emphasizes the significance of financial support from the European Union and the involvement of local organizations in preserving the biodiversity of the area.
The potential threats to leech habitats, including siltation, encroaching vegetation, and pollution from veterinary treatments, underscore the delicate balance required to protect these unique species.
