I emailed Fairburn Ings to find out what's happening with St Aidans and got the following reply: "Harworth Estates and Leeds City Council are still resolving their dispute, and this is taking some time.  Once that is resolved, Leeds City Council will lease the site to RSPB but there is currently no known timescale for this.  So currently it is not an RSPB site." It's rather disappointing, but seems to be nothing that the RSPB can do to move things along
