How to fix this issue

Your dataset is missing the designation-date column.

The Conservation area guidance explains how to fix the issue:

designation-date

The date that the conservation area was officially designated, written in YYYY-MM-DD format.

Example:

1984-03-28

With dates, some data is better than no data, so:

1984 is fine
1984-03 is better
1984-04-28 is brilliant
