Data Wi 
ot 
Three sets of numerical data were used in this study t 
i) The subjective values (allocated by a group of eminent ecologists) 
in which each habitat type was allocated a relative number in 
terms of its conservation value. Bi 
us 
The average values are listed in Table 4. uj 
ii) The objective habitat values derived from standard texts, for each I 
aspect of the three parameters considered (Table 5) i.e. Plant WI 
Species Diversity, Vertical Structure, and Local Scarcity. 1 
p 
iii) The quantitative values of the areal extent of each type of unit 9 
included in the Habitat Survey Maps (Figures 1 and 2) for each m 
1/4 km square. a

d 
From this data it was possible to derive sets of values for each 1/4 km pP 
square for each of the three parameters and for the Ecologists Habitats. p

A. Gairloch I 
Seventeen maps and six graphs were obtained of the Gairloch area. a 
p 
The graphs show the correlation between the Ecologists Habitats as 0 
determined by the values given by the 'eminent' ecologists with each of p 
the other parameters used. :

Figure 6 shows the correlation between Ecologists Habitats and Species I 
Diversity. The correlation co-efficient of 0.467 suggests that Species r 
Diversity is a good indicator of conservation value in an upland area. 
This correlation can also be seen in the calcomp computer maps of C 
Ecologists Habitats (Figure 7) and Species Diversity (Figure 8). The 
correlation co-efficients of the other parameters are also determined. 
B. Merseyside 
Nine maps and five graphs were obtained of the Merseyside area. These 
graphs also show the correlation between the Ecologists Habitats with the 
other parameters used.

Figure 9 shows the correlation between Ecologists Habitats and Vertical 
Strata. The correlation co-efficient of 0.956 suggests that Vertical Strata 
'is a good indicator of conservation value in a lowland area. 
This correlation can also be seen in the calcomp computer maps of Ecologists 
Habitats (Figure 10) and Vertical Strata (Figure 11). The correlation r 
co-efficients of the other parameters are also determined. (
