Is Local Best?

Autumn leafTrees of local origin and their ancestors have grown in the same area for hundreds of years. Over this time, natural selection will have favoured trees that are adapted to local conditions and are resistant to local pests and diseases.
In addition to local adaptation of the trees themselves, the local wildlife will have adapted to make the best use of the trees in their habitats. In particular, animals and birds may time their life-cycles to when the trees that support them come into flower or produce fruit. Because of differences in climate and seasons, a tree originating from a different part of the UK or abroad may flower earlier or later in the season. Such a change can make a huge difference for the wildlife which relies on that tree for food.
This means that seed collected from these trees can not only offer better rates of establishment, growth and survival, but may also benefit the wildlife where they are planted.
