Our Estate woodlands are managed on a sustainable basis, ensuring that an equal area is felled, thinned, and restocked each year. This approach aligns with the UK Forest Standard, emphasising sustainability as a way to meet current needs without compromising future generations.
We primarily employ a clearfell-and-replant system, with coupe sizes ranging from one to twenty hectares. This method maximises efficiency and production while minimising costs in commercial coniferous woodlands. For the broadleaved woodlands near Alnwick Castle, our goal is to maintain continuous tree cover by selectively clearing smaller areas for restocking.
After clearing, branch wood is managed through burning or windrowing to facilitate replanting. Deer fencing is used as necessary, and individual tree protections like grow tubes are employed. Planting occurs from November to April, with densities of approximately 2,500 trees per hectare for conifers and 1,700 for broadleaves. Historically, we grew our own transplants on the Estate, but now we source from commercial growers to ensure high-quality, genetically diverse stock.
Routine maintenance, inspections, and careful thinning operations begin at around 20 years of age, with the aim of promoting the best trees while ensuring ecological stability.
