1. ELC for CWR
Diversity assessment and gap analysis
Mauricio Parra Quijano
Ecogeographic land characterization for CWR diversity and gap analysis
Training workshop
26–27 February 2014, Room UG08, Learning Centre, University of Birmingham

2. ELC overview
It is a made-to-measure map according to researcher needs to
discriminate adaptive scenarios within a work frame
≠ Abiotic
adaptation
≠ Adaptive

diversity

3. ELC overview
How to delineate different adaptive scenarios in a work frame?

4. ELC overview
How in the past most of these type of maps were delineated?
DMEER - EEA, 2003

5. ELC overview
But what about abiotic masked conditions related to plant
physiology-adaptation?

6. ELC overview
Right now we have enough tools to achieve our own plant abioticadaptive maps thanks to

and you also know the total possible scenarios for the target species (from
known populations)

10. In situ gap analysis
… from an ecogeographical point of view, are you including key
populations in your protected areas?

12. Why this approach works better for CWR?
… it’s about time
Human influence (domestication)
Specific environmental adaptation

13. Ecogeographic Land Characterization Maps
For ex situ conservation can be used as a base of:
 Massive/fast ecogeographic germplasm characterization
 Representativeness assessment in germplasm collections
 Core collections
And complement of other interesting methods such as:
 Optimized germplasm collection
 FIGS

14. Ecogeographic Land Characterization Maps
For in situ conservation this methodology has been used only as a
criterion in studies to:
 Identify populations with high priority to be conserved
 Identify protected areas which contain target environments / are
covering priority populations
 Determine optimal places for genetic reserves
 Establish CWR national strategies
 Prioritize sites to focus on on-farm conservation efforts
