I use Recorder, that way your data can go straight into the database at your local Data Centre, where it can be used to inform better planning and protection of the things you like to ID.
I know some people don't like their data being shared, but as an example, I know of a wood that contains specimens of quite unusual trees, some were cut down as only one person knew of the locations. Also I believe that the type specimen of one of the rare Whitebeams found in the Avon gorge got cleared away by a working party clearing space to plant... rare Whitebeams! (not a scientific report that, just think I read it somewhere.)
If you are currently using Excel, try this,

Or search for
excel database tutorial, there seem to be loads of free stuff out there.
Access can be very powerful, but daunting, and Some updates to the software have left some custom written databases unuseable without extensive re-writing.
Occam's razor!
