Once all of the factors were standardized and the constraints were set as Boolean images, the MCE could be preformed. Using MCE and the Weighted Linear Combination (WLC) factors and constraints were combined and it was possible to show the suitability of the ecosection for the reintroduction of the lily. This suitability depended on how factors were weighted against one another. Because this process is extremely subjective, a small sensitivity analysis was preformed to show how different factor weights can yield different suitability images. The first MCE preformed weighted the factors evenly. The second MCE was weighted towards the land use factor. The third MCE was weighted towards the biogeoclimatic zones. For each MCE, the Analytical Hierarchy Process (AHP) was used to help give a more realistic comparison of the factors. The AHP allowed for the relative importance of each factor to be compared with the importance another factor one at a time. For the rating scale associated with the AHP and the Pairwise Comparison, a scale is shown below each AHP table.

The first MCE preformed using the WLC set all factor weights to be equal. Because there are 5 factors, each factor was given a weight of 0.2000, since all weights must add up to 1. Because all weights were equal, there was no need to perform the AHP. The resulting suitability map can be seen below.

Aspect: 0.2000
Elevation: 0.2000
Lily Distance: 0.2000
Land Use: 0.2000
Biogeoclimatic Zone: 0.2000

The second MCE preformed weighted the land use factor more heavily. The land use factor contains very important qualifications for the mariposa lily’s reintroduction, including protected areas, forest cover and rangeland. Because the other factors still play a vital role in determining the final suitability, it was not advantageous to weight land use extremely heavily, for example around 0.5700 and up, and have all other factors weighted quite low. For this MCE, the AHP was preformed.

Aspect: 0.1243
Elevation: 0.1243
Lily Distance: 0.1350
Land Use: 0.4276
Biogeoclimatic Zone: 0.1889
Consistency ratio = 0.07 (acceptable)

	Aspect	Elevation	Land use	Lily distance	Biogeoclimatic zones
Aspect	1
Elevation	1	1
Land use	5	5	1
Lily distance	1	1	1/3	1
Biogeoclimatic zones	1	1	1	1	1

The third MCE preformed put more weight onto the biogeoclimatic zones factor. As with the MCE weighted towards land use, it was not advantageous to over-weight the biogeoclimatic zones. The weights for all other factors were set similar to those used in for land use. An AHP was also preformed for this MCE.

Aspect: 0.1284
Elevation: 0.1284
Lily Distance: 0.1243
Land Use: 0.1894
Biogeoclimatic Zone: 0.4295
Consistency ratio = 0.06 (acceptable)

	Aspect	Elevation	Land use	Lily distance	Biogeoclimatic zones

Elevation	1	1
Lily distance	1	1	1
Biogeoclimatic zones	4	4	5	1
