These statements are similar to the Region statements described in the

previous section in that they defi ne the four corners of each region or

rectangle, although here, output data for each described individual rectangle

will be reported separately by NEWGARDEN. Note fi rst that the Summary

Regions statements also include region statements that function exactly

like the Region statements described in the previous section. That is, here

the region statements again defi ne the entire grid system within which the

preserve-corridor-preserve system exists. The rectangle statements then

describe the different summary regions for which data will be reported

separately. In the above example, the fi rst summary region for which output

data will be reported includes exactly the same boundaries and points

included only in the left preserve just described in the previous section (this

will be denoted as subregion “1” in NEWGARDEN output). This statement

will invoke NEWGARDEN to provide the output data analyzed only for

that left preserve. The next two rectangle statements generate output data

for the corridor (output denotes this as subregion “2”), and then for the

right hand preserve (subregion “3”).

The Grid System: Some Considerations

We emphatically acknowledge that the species average density grid

system used here is by no means an absolutely accurate representation of

reality. Some of these shortcomings will be discussed in the section Spatial

Arrangement of Founders below, and others will become apparent as we

explore different NEWGARDEN analyses in later chapters. We also note that

a non-grid system was tested with an otherwise identical NEWGARDEN

program, and it made little or no difference in our conclusions regarding

comparative trials (unpublished data, S. Pelikan).
