Based on the extracted 288 representative farms in Al-Ahsa oasis, the quantitative distribution of date palm trees has been mapped using the number of trees per farm, which was categorized into four ranks (i.e., low, \(<\)50; medium, 51-100; high 101-200; very high, \(>\)200 tree/farm) (Figure 3). The Figure includes four maps describing the spatial distributions of the total palm trees (a), Khlas cultivar trees (b), Ruzzic cultivar trees (c), and Shishi cultivar trees (d). It can be noticed from the total palm trees (Figure 3a) that the general orientation of tree density (i.e., 101-200 and \(>\)200 tree/farm) is localized in the northern (i.e., Jlejilah) and central (i.e., Al-Harah) subregions of the oasis. However, the eastern subregion (i.e., Al-Mansourah) shows a lower density of trees, as most farms contain 100 trees/farm or fewer (i.e., 50-100 and \(<\)50 tree/farm). The spatial distribution of studied cultivars, however, exhibits that the Khlas cultivar also shows a similar quantitatively dominated and intensive cultivation (i.e., 101-200 and \(>\)200 tree/farm) in the northern and central subregions of the oasis, with a much lower tendency in the eastern subregion (Figure 3b). However, the Ruzzic cultivar shows a noticeable quantitative concentration of farms in the central subregion (Figure 3c), particularly in the southwestern corner where Al-Hofuf city is located, with a scattered distribution of a few farms in the eastern subregion. The Shishi cultivar, however, displays a limited quantitative intensity of farms in the central subregion as they are mostly localized by the top border

Overall, Figure 3b-d also embodies the distribution of small ranks (i.e., 51-100 and \(<\)50 tree/farm) of these cultivars in the oasis, implying their cultivation importance among the farmers of the Al-Ahsa oasis. As indicated earlier, the study intended to plot the spatial distribution of farms' cultivated areas to reveal the differences in the ownership sizes of the farms throughout the oasis. Thus, Figure 4 shows the four maps that depict the distribution of oasis cultivated areas with all cultivars (Figure 4a), the Khlas (Figure 4b), the Ruzz (Figure 4c), and the Shishi (Figure 4d) cultivar. All maps were plotted in four ranks being divided on the basis of the common range of cultivated areas (i.e., \(<\)500; 501-1000; 1001-10,000; \(>\)10,000 m\({}^{2}\)). These ranks of cultivated areas were presented as low, medium, high, and very high, respectively, for all cultivars as well as for each sole cultivar.

For all studied cultivars, it is possible to see from Figure 4a that the dominant cultivated area rank was the high class (i.e., 1001-10,000 m\({}^{2}\)) being sited over most of the Al-Ahsa oasis, followed by the medium class (i.e., 501-1000 m\({}^{2}\)), with a few small clusters of cultivated areas of very high class (i.e., >10,000 m\({}^{2}\)) that were depicted in the central subregions of the oasis. On the other hand, the low class farms (i.e., <500 m\({}^{2}\)) were found mainly in the eastern subregion of the oasis. These findings are in line with the distribution of palm tree numbers in the oasis (Figure 3a). Similarly, the cultivated areas of each cultivar, presented individually in Figure 4b-d for the Khlas, Ruziz, and Shishi, respectively, revealed marked variations in their spatial distribution. The Khlas cultivar, for instance, was found to be the dominant cultivar grown in the oasis, as seen in Figure 4b, which also displays the dense and wide areas of its cultivation throughout the oasis.
