With almost 30 years of experience in forestry and forestry policy, Seddon was previously director of operations at the Forestry Commission, and before that its forest management director for southern England.
"From an emerging climate crisis to wildlife decline, the challenges for the next century will be tough, but I am driven to expand on the great things the nation’s forests already achieve today," he said.
"Our forests welcome more than 230 million visits every year, and we will make forests even more accessible by planting some forests closer to where people live. As they grow they will create places to relax and improve people’s physical and mental health.
"All of the forests in our care will continue to work for society and we will increase their natural capital. From cleaner air and reduced flooding to walking trails and play equipment we are making wildlife-rich, connected landscapes. We will also need more forests to absorb carbon while they grow and we can keep that carbon locked up by using more timber products."
