Invertebrate Field Recorder Day

Recording invertebrate species allows us to track the diversity, abundance, and health of organisms that are vital to ecosystem functioning. By knowing which invertebrate species are present at a site, land managers are best informed to protect and enhance ecosystems effectively. In London, recording and monitoring invertebrates is particularly important because the capital often serves as the first point of arrival for species new to Britain, making early records crucial for detecting and managing potential ecological impacts. London’s brownfield sites also provide valuable refuges for specialised native species that are declining elsewhere. We also face challenges from invasive invertebrates – careful recording helps to identify and control these challenges. Beyond its scientific value, invertebrate recording is a rewarding and enjoyable activity that fosters a deeper connection with nature.

Join the London Natural History Society recorders for a day of finding, identifying, and recording invertebrates. Whether you're a beginner or an experienced naturalist, this event offers a great opportunity to share knowledge, build confidence in biological recording, and refine your identification skills.

What will the day involve?

• Hands-on experience using different methods to collect and record a variety of invertebrates.
• Guidance on identifying invertebrates in the field and understanding which specimens require further examination under a microscope.
• Practical experience in fieldwork, specimen collection and preservation.
• A chance to connect with like-minded individuals from diverse backgrounds who share an interest in entomology and wildlife recording.

What do I need to know in advance?

• This event is aimed at adults only. 
• Attendance is free, but booking is essential as spaces are limited.
• Invertebrate recorders of all abilities are welcome.
• Identification will take place in the field whenever possible, but some invertebrate specimens may need to be collected and preserved for accurate identification under a microscope.
• We'll be outside for the whole day so please bring suitable clothing for the weather
• Please bring food for the day with you (i.e. lunch)
• All records generated will be added to iRecord in order to share our findings with the site managers, Greenspace Information for Greater London (GiGL), London Natural History Society (LNHS) and relevant national recording schemes and societies.

Welsh Harp (Brent/Barnet)

Welsh Harp (also known as The Welsh Harp, Welsh Harp Open Space or alternatively, Brent Reservoir) is a Site of Special Scientific Interest (SSSI) and Local Nature Reserve (LNR) in North London, on the boundary of the boroughs of Brent and Barnet. Originally built in the 1830s to provide water for London’s canals, the site comprises 170 acres of open water, marshes, woodland and grassland. It is recognised as one of the most important bird breeding areas in Southern England. The varied habitats also support a range of other wildlife.
