Rediscovery of ancient wetland plant

20 December 2020

Ponds Group attracts national interest

Rediscovery of ancient wetland plant

In the last week of November the work of 果冻影院 Geography鈥檚聽Pond Restoration Research Group聽hit the press with the rediscovery of a rare and endangered wetland plant.

In late summer 2020 the Ponds team were surveying in mid-Norfolk along the high water mark of a farmland pond restored last winter by the聽.

At the very end of the day, out of the corner of an eye, a plant was seen that was not immediately recognised. Professor Carl Sayer sent a photograph to a local botanical expert, and six plants of Grass-poly聽Lythrum hyssopifolia聽L. were confirmed. This is the first confirmed record of the plant seen in Norfolk for over a century.

The 果冻影院 Ponds team have previously demonstrated that the seeds of many wetland plants are extremely long-lived. Remarkably, even ponds in-filled and ploughed more than 150 years ago (so-called 鈥楪host Ponds鈥) have been shown to support viable seeds.

The next question with Grass-poly is how to keep it going and increase its population. 果冻影院 Geography鈥檚 Helen Greaves has a plan:

鈥淎s regular disturbance is needed for the survival of Grass-Poly, we have been thinking about how we can maintain our population. We might need to carry out regular winter raking or introduce some cows or maybe a Christmas pantomime horse would suffice if we get stuck."

"Whatever the method, we are desperately keen to keep the plant above ground now it has come back to us鈥.

The Grass-poly story was covered in a聽, and was featured on BBC Radio 4 and the BBC Breakfast programme. Carl was also interviewed on BBC News 24.
