Change Registers

Introduction

The following are the Change Registers recording additions, reclassifications and deletions to various listings, many of which are co-authored with either Aled Williams or Michael Dewey.  However, some include listings by other authors where status change has occurred because of surveys or through map study that I have conducted, others relate to listings where I am the sole author.  The links to the Change Registers will appear on this page when their detail is complete.

Each Change Register is preceded with an Introduction giving brief details of the respective list, including its authors, criteria and date of publication, with the changes to each list being presented chronologically in receding order.
