A park trust in Leicestershire has built fencing around some of its historic oak trees in a bid to improve their health.
Bradgate Park Trust said it was taking special measures to stop soil compaction beneath the trees which can affect the main upper part of the tree, known as the crown.
Some of the 12 fenced-off trees are more than 400 years old and are believed to date back to when Lady Jane Grey, who was famously Queen for only nine days, lived at Bradgate House in the 16th Century.
Matt Molesdale, senior ranger on the park, said the project will help protect the trees from visitors and a changing climate.
It is hoped the project will prevent the soil surrounding the root systems from becoming compacted, which could cause the trees struggle to absorb water and nutrients.
Last month it was announced that the Major Oak in Sherwood Forest, Nottinghamshire, which is believed to be more than 1,200 years old, had died, due to a combination of soil compaction and high visitor numbers.
The Bradgate Park project also aims to protect visitors from the risk of falling branches from the old trees.
