GWCT Research Report 2025 - Partridge Count Scheme
04 Jul 2026
The recently published GWCT Research Report 2025 provides details about the Partridge Count Scheme: "Grey Partridge Counts" by Morgan Hartman & Julie Ewald (p 56-57).
Partridge counts offer valuable insight into how well partridges breed, survive and benefit from habitat management and provision throughout the year. The Partridge Count Scheme measure how well the birds have fared during the previous six months, when they are easily monitored, with counts recorded in spring and autumn.
Weather conditions play a significant role in shaping the breeding season. Winter 2024/2025 was milder than average, except for a brief spell in January. Spring 2025 was the warmest recorded since 1884, followed by the warmest UK summer on record. Harvesting began unusually early in parts of the country due to the prolonged dry conditions. This extended dryness also raised concerns about insect availability for grey partridge chicks: insects depend on moist – not dry – conditions. An adequate food supply is key to chick early survival and development.
Key Findings
- National average spring pair density on Partridge Count Scheme sites decreased to 4.7 pairs per 100ha, down 8% from 2024.
- Summer productivity, measured as Young-to-Old ratio, increased to 3.1 young birds per adult, well above the level needed to maintain grey partridge count numbers.
- Autumn 2025 saw improved counting participation wih 398 counts returned, an 11% increase on 2024.
- National average autumn density increased by 40% to 25.1 birds per 100ha, with all mainland regions except southern England and Scotland showing substantial increases.
The strong breeding season and improved autumn densities provide an encouraging foundation for 2026.
