Woodland Maintenance ( The best way to manage farm woodland at this time of the year).
Updated: May 19, 2020
It’s important to look at your woodland in the context of other trees. What’s going to be there in the long term? Don’t assume that just because you’ve got 20 oak trees, they’re all going to survive.
Assuming you have relatively new woodland, currently you’d normally be thinking about thinning and pruning anything from 5 -10 years old with a view to raising the canopy a little. It’s when they reach this age that trees start to compete for space, light and nutrients and the growth rate starts to slow. Thinning makes sure the best trees grow at the fastest rate, allowing for a more diverse woodland structure and helping to future-proof the landscape.
You can probably afford to prune up to two thirds of a tree if it’s good and strong. Take off the side shoots and this will encourage the tree to grow in the best possible way for timber. The most valuable trees have long, straight, branch-free stems.
For anything over 10 years old, especially if planted at a density of 1,600 trees per hectare, you would be looking to thin out one of every four of five trees. Pick out the ones you want to keep - the good quality ones, the strongest and straightest. Most trees tend to get planted in blocks of 15. I like to stand in the middle of a block, look up, decide which ones I want to keep then free the canopy around them - cutting away any trees touching the canopy of the ones I’m going to retain.
Anything you cut up you can take back to the farm for your log fire, or make it into wood chips and sell it on, although it’s always good to leave some stacks on the ground as it benefits insects and wildlife, especially hedgehogs. And that’s something else to consider before starting any sort of woodland management - look out for wildlife. Check for nesting birds, bats, dormice and other animals, and be careful not to damage other woodland plants. You’ll also want to beware of soil erosion and run-off if the work causes any ground disturbance.
When you’re pruning, you’re ultimately trying to get a nice thick under story. Hazel is a great under story tree as whatever you do to it, it won’t impact on your taller trees - the elder statesmen, as it were. From around 7 years you can start to coppice hazel, but make sure you only tackle the well matured trees with good root stock. And whatever you’re pruning, always take out damaged or diseased trees first.
If your woodland is dark and not had much done to it for a decade or more, think about opening a ride or creating some glades - something to let the light in and encourage growth, not just of your trees, but of other plants and flowers on the floor.
Whatever you’re cutting back, always plan your extraction routes. It’s important that you can remove your timber and, of course, your machinery. Normally felling licences are not required for pruning or thinning of young woodland but please read through the Forestry Commission’s guidelines prior to any work taking place to make sure you don’t require one.

The Woodland Trust has published a handy guide to managing your woodland. It’s full of top tips and explains the differing techniques - coppicing, pollarding, formative pruning and thinning - and also examines the sort of work you should be carrying at each stage of your woodland’s life, whether it’s less than 5 years old or more than 50.
