good and challenging blog on the need to plant trees but with the cvaeat to plant locally-sourced trees to retain genetic variety
Warnig of the danger of large stands of genetically identical trees, whether officially native or not
In Conservation our goal is primarily about conserving the widest range of genetic diversity within each species in a given area. If each area conserves their local genetic diversity of a native species then we will end up with the most diverse/robust option across the country, given our current starting point. We need to conserve that breadth of genetic variation and then create an abundance of that breadth to put us in the most resilient position possible to face a future of climate change and the new pests/diseases that may appear in a given area in the UK.
Natural regeneration of Oak and Birch on heathland.
The best-practice way to achieve that with trees is through natural regeneration of locally native trees i.e. the trees naturally produce seed and that seed germinates nearby and grows to produce new trees. In many places the site where trees are wanted can be…
