1.0 INTRODUCTION 
The  main  objective  of  this  project  was  to  update  the  existing  Southern  Gulf  Islands  
(SGI)  ecosystem  mapping  (Greene  2004)  to  terrestrial  ecosystem  mapping  (TEM)  
standards.    The  goal  of  this  office-based  exercise  is  to  make  the  existing  ecosystem  
mapping  consistent  with  the  rest  of  the  TEM  mapping  completed  in  2008  for  the  
Coastal  Douglas-fir  (CDF)  biogeoclimatic  zone  (Madrone  2008).  Islands  Trust  
requires  this  information  in  order  to  have  a  single,  consistent  ecosystem  mapping  
platform  for  identification  of  Sensitive  Ecosystems  for  identification  of  areas  and  
properties of high conservation value. 
 
2.0 METHODS 
All coding used in the existing mapping was upgraded to TEM standards (RISC 1996; 
RISC  1998a;  RISC  1998b;  RISC  2000)  where  applicable  (please  refer  to  the  below  
step-by-step   methods   provided   below).   Where   this   information   could   not   be   
converted  to  TEM  standards  “User-defined”  columns  will  be  applied  wherever  
possible  to  retain  the  detail  from  the  original  mapping.  The  final  “cross-walk”  
conversion  table  for  SGI  ecosystem  mapping  to  TEM  standards  is  provided  in  
Appendix 1.

Steps Applied for SGI Conversion to TEM: 
1. Developed  a  “cross-walk”  table  to  follow  for  consistent  conversion  of  SGI  
ecosystem labels to TEM standards (Appendix 1). 
2. Created  a  new,  blank,  provincial  standard  TEM  workbook  in  Excel.  Began  
transfer  of  data  from  SGI  database  to  the  TEM  workbook  (to
