I agree to a large extent with Robert Read about 2ha surveys being
misleading about the species in an area.
I strongly support the Atlas, but I simply go birding rather than plan my
trip to maximise Atlas results!! I record all that I see at each stop and
then complete the Atlas form accordingly. <30 minutes and within 2ha, then
I call it a 2ha suvey. Otherwise a 500m survey. For longer surveys, I
sometimes try to break my list in two or more surveys rather than put in a
5km survey.
To Atlas all species in the area I put in a very large number of incidental
surveys, particularly when driving. It is a simple matter of double
clicking to save a way point on my GPS as I drive. This includes
incidentals for reasonably common species. I also record all species seen
/ heard at the incidental. e.g. I stop for a Long-billed Black-Cockatoo,
and I will put Australian Magpie, Australian Raven, etc on the survey with
it if I see it, or see it within a short distance.
The big problem is that it oftens seems that I spend more time writing up
my records than I have spent birding!!
I do have the map of the 10 minute blocks for the south west of WA. So if
I am passing through a block with very few surveys, I do try and stop and
complete a 20 minute plus survey wherever possible.
