Clement Okoye of Leyton, London and Mohammed Alam of Upton Park, London have been ordered to pay fines and court costs after dumping rubbish on Wanstead Flats, cared for by the City of London Corporation.
Okoye was fined £1,000 and £819 costs after depositing building materials including roof lagging on the flats, in east London. Alam was fined £150 plus £100 costs and a £30 victim surcharge for dumping a wardrobe, cardboard packaging and a bed base.
The corporation, which manages the ancient woodland of Epping Forest and Wanstead Flats, brought the prosecutions at Thames Court.
Epping Forest head keeper Martin Newnham said: "Fly tipping in Epping Forest is completely unacceptable and we take a zero-tolerance approach to it. It is unsightly, dangerous and damaging to the environment.
"Our job is to protect this ancient woodland and we will prosecute anyone found to be carrying out this sort of illegal activity."
A live cat, a goat, several large dogs, a dead donkey and 16,000kg of building waste are just some of the things that have been dumped in Epping Forest in recent years.
The City of London Corporation offers a £500 reward to anyone who can provide evidence which leads to prosecution for fly tipping.
It cleans up an average of 600 fly tips and 300 tonnes of rubbish every year in Epping Forest at a cost of £250,000 and volunteers spend more than 7,000 hours a year collecting litter in Epping Forest.
The City of London Corporation manages 4,452 hectares of green space across London and south east England, including Hampstead Heath and Burnham Beeches, with many of its sites designated National nature Reserves and Sites of Special Scientific Interest for their unique ecology and rare plant species.
Epping Forest is London and Essex’s largest open space and attracts nearly five million visits a year.
In December landlord Shahzad Khan of Walthamstow was also ordered to pay £1,000 after his commercial building waste was found in Epping Forest.
