November 2024 – Demonstrator Hub Updates

The Biomass Connect Demonstrator Hubs across the UK have shown varying progress as winter approaches, reflecting both the resilience of certain crops and regional differences in weather conditions. Across the sites, senescence is a dominant theme, with many perennial crops entering dormancy while some continue to show growth in favourable conditions.

Many areas experienced a mild and extended autumn, which promoted continued growth for species like Eucalyptus and Miscanthus. However, recent frosts at certain sites, such as Auchincruive and Aberystwyth, have accelerated senescence for more sensitive crops. Regional rainfall levels have also impacted ground conditions, with some sites reporting softened soils affecting tree stability and increasing weed pressures. We have even seen an unusually early snowfall at some sites such as Chesham , followed by some damaging winds as Storm Bert hit over the weekend of the 23^rd/24^th of November.

The Miscanthus crops generally remain robust, with Miscanthus giganteus showing good height and structure, though some lodging has been observed at sites like North Wyke in Devon and Hillsborough in Northern Ireland due to wind and snow. Miscanthus Athena continues to thrive in many locations with green shoots appearing even after heavy frosts. Senescence has started in the Miscanthus across all sites.

The woody crops, including Alder, Poplar, and Willow, display widespread senescence, though they remain structurally sound. A notable observation is the resilience of Eucalyptus, with healthy growth and minimal damage reported at most sites, despite some leaning issues at Headley Hall. The Willow crops are generally senescing well, with allelopathy visibly reducing weed competition under the now quite mature stands.

Management efforts have been consistent across hubs, including mowing and herbicide applications.
