There are a couple of schemes that ask people to record wildlife seen in gardens on a regular basis.
The Garden Bird Survey run by the British Trust for Ornithology (BTO) has been running for decades and has collected a lot of information about trends in birds using our gardens. What they are asking you to record is the birds you have seen in your garden on a weekly basis. If you are interested in this go to https://bto.org/our-science/projects/gbw this is a completely different affair to the RSPB Great Garden Birdwatch which is just about recording birds seen on a single day.
Another much newer scheme is Butterfly Conservations Garden Butterfly Survey, again it asks people to record on a weekly basis butterflies seen in the garden. Running since 2016 they reckon to have received over 70,000 records from some 1,000 gardens around the country, so why not think about addhttps://gardenbutterflysurvey.org/ing yours to the list. For more details go to https://gardenbutterflysurvey.org/ These are both valid contributions to our knowledge of these species groups and well worth supporting, with the added bonus you can have a cuppa tea and a biscuit whilst doing it.
And don`t forget Nature Counts for more widespread records https://record.nottinghamshirewildlife.org/
