While winter tasks in the Wildlife Garden kept most of us busy outside for the first quarter of the year, these cold months are also a good excuse to hunker down inside and look back at the previous season’s species records, enter new records on our database and consolidate reports on our findings.
As mentioned in one of our early blogs biological recording is carried out – like most activities here – with the help of many volunteers (specialists as well as beginners), and naturally our own scientists, during the course of their working day. Sometimes we enlist the help of aspiring young scientists…
Recording is carried out by observation and surveys. From mosses on walls, rocks and bare ground and the animals that inhabit these miniature forests, to the tree tops where great and blue tits may be spotted feeding on aphids and other small insects in the upper branches, as well as high flying butterflies such as the purple hairstreak that feed off honeydew.
Invertebrate surveys are carried out using a variety of methods including pitfall traps for ground invertebrates, malaise traps for flying insects, and light traps for nocturnal fliers.
