Personally, I favour 2.0-minute grids for the reason that you outline
above. However, there are some scientists in Canberra who are
suggesting much smaller grid blocks in some areas. One suggestion that
I heard last week is that some regions be divided into 100 X 100 m
grid blocks, particularly in some forest regions to help with RFAs,
etc. Although I can see some value in doing this, I think it is
unrealistic to expect atlassers to collect data on such a fine scale,
and so I will be arguing against doing this, unless I can be convinced
it is possible."
I would agree that the grid block size will be discussed thoroughly at
Just to let everyone know that Canberra Ornithologists Group has been
collecting data on its area of interest of the ACT and surrounding
region based on a grid size of 2.5 minutes. This includes data for
the ACT Bird Atlas published some years ago. I understand the
Cumberland Bird Observers Club is doing the same thing. The issue of
grid size makes a lot of difference to regional organisations such as
these in coming to an arrangement of how regionally co-ordinated
atlassing meshes in with the national plan.
I also understand that there would be strong arguments for using a
much larger grid size in much of Australia.
The concept of a 100m by 100 metre grid blocks for even some areas in
a continent the size of Australia needs some careful thought, for a
moment at least.
