A new seed processing center in Cheshire will process four tonnes of tree seeds annually, providing genetic material for millions of climate-adapted trees across Britain.
Forestry England opened its seed processing center at Delamere in September 2025. replacing the previous facility at Alice Holt Forest in Surrey, which had operated since 1964. Named in honor of Vernon Stockton, who worked in Forestry England’s plant and seed supply operations for more than 40 years before passing away in 2022, the new center represents the largest investment in Britain’s tree seed infrastructure in decades. The center will strengthen the country’s capacity to grow forests suited to warmer, drier conditions.
The timber-framed center handles seeds from species identified through research as better adapted to the changing climate. Douglas fir, western red cedar, and Norway spruce rank among the focus species. These trees grow well in the conditions Britain can expect in the coming decades, while providing high-quality timber.
The seed processing center processes seeds collected from 12 specially planted seed orchards and 29 seed stands spread across 300 hectares of national forests. Forestry England plans to expand this network to increase the supply of genetic material suited to future climate conditions.
The seed availability fluctuates dramatically from year to year. Peak years can produce four tonnes of seeds to store before processing and germination. The processing center provides flexibility to respond to seasonal supply variations.
The seed processing center forms a cornerstone of the strategy to plant forests that can withstand extreme weather, biodiversity loss, pests, and diseases. Each tree dispatched to foresters begins as an individual seed processed and grown with care at the facility.
The center features advanced equipment, including cone dryers for conifer seeds and gravity tables that sort and grade seed material. Additional machinery installed includes a 3D X-ray scanner to measure seed quality and a laser sorter to improve processing accuracy and speed. These steps ensure only the highest quality material reaches nurseries.
Climate-controlled storage can preserve both conifer and broadleaf seeds for up to 20 years. Storage capacity enables Forestry England to accumulate seeds during productive years and maintain a stable supply during lean periods. Many tree species produce heavy seed crops only every few years. The ability to store seeds under optimal conditions for two decades smooths out these natural fluctuations.
Forestry England anticipated supplying approximately 450 kilograms of conifer seeds to the private sector in 2025. The organization will also plant 7.5 million trees in national forests. Building a secure domestic supply reduces reliance on imported seeds while boosting diversity in timber-producing species.
The 2,000-square-meter building was constructed using cross-laminated timber framing as a sustainable alternative to steel, concrete, and masonry. The structure will operate at net-zero carbon. Solar panels, triple glazing, and sustainable drainage systems enhance environmental performance. The building was completed for approximately £14.5 million.
Funding for the seed processing center primarily came from the government’s Nature for Climate Fund, with additional investment from Forestry England. The project enhances Britain’s capacity to supply genetic material for woodland creation and regeneration through the rest of the century.
The seed processing center will significantly expand its capacity to process seeds from a wider variety of tree species. Forestry England published a research last fall identifying which species will receive priority for growing and planting. All selected species are expected to thrive as sources of sustainable timber in drier, hotter conditions.
The network of seed orchards and stands provides carefully controlled genetic material. These dedicated growing areas ensure seeds come from trees with desirable characteristics such as straight growth, disease resistance, and climate adaptation. This selective breeding improves the quality of forests planted decades into the future.
The center prioritizes long-term forest health over immediate needs. Trees planted today will mature over 50 to 100 years. Selecting appropriate genetic material now determines whether those forests can survive mid-century climate conditions.

Britain imports significant quantities of tree seeds from overseas suppliers. The expanded processing center reduces this dependency while ensuring seeds come from stock adapted to British growing conditions. Trees grown from locally sourced seeds typically perform better than those from distant origins.
The facility supplies both public and private sector forestry operations. Private nurseries purchase seeds to grow trees for commercial forestry, estate management, and conservation projects. This dual role makes the center an important infrastructure for Britain’s entire forestry sector.
The seed processing center supports Forestry England’s goals to plant at least 2,000 hectares of new woodlands by 2026 and increase forest diversity through integrating rewilding activities. These objectives require millions of trees grown from seeds processed at the Delamere facility.
Britain manages 1,500 woods and forests, receiving 285 million visits annually. The seed processing center ensures these landscapes can adapt to climate change while continuing to provide timber, recreation, and ecosystem services. The investment in seed infrastructure protects these benefits for future generations.
