Head of education and community engagement Toni Assirati said: "As 2012 draws to a close the Royal Parks has launched a number of new volunteering opportunities. We have extended the range of volunteering roles on offer in our parks."
Assirati said: "In Regent’s and the other central London parks we need volunteers with some pre-existing wildlife knowledge to identify species of plants, birds, fungi, lichens, insects and other invertebrates."
Meanwhile the lottery funded Isabella Plantation Access Project in Richmond Park needs gardening volunteers as part of a drive to make the site more accessible to volunteers.
Other posts include assistants to take bookings and biological records and to offer guided tours.
Almost 40m people visit the eight Royal Parks each year. They are Bushy Park, The Green Park, Greenwich Park, Hyde Park, Kensington Gardens, The Regent’s Park and Primrose Hill, Richmond Park and St James’s Park.
