Trackside land must be maintained to avoid leaves on the line but residents should be kept informed, according to a report from the London Assembly.
Residents said they felt trackside land gave them privacy and shielded them from dust and noise but maintenance work was not always explained and was sometimes excessive – such as where mature trees were removed.
The report, compiled by London Assembly member and Environment Committee chairman Darren Johnson, recommended that companies give specific detail about work and liaise closely with the London Biodiversity Partnership.
Most of the trackside land in the capital is owned by Network Rail or Transport for London and the report found that policies for managing this land were mainly good.
The 724km of trackside amounts to 10% of green space in the capital and provides a home to wildlife such as kestrels, orange-tip butterflies, great spotted woodpeckers and bats.
