11. This drought-and heat-tolerant species grows in many types of substrate, including caliche, limestone, and gypsum. 12. Natural selection can also cause a replacement of less tolerant species with more tolerant species . 13. This drought-tolerant species is often used in xeriscaping. 14. It may tend to push them out and you may get more non-native or salt-tolerant species . 15. On the salt marshes along the eastern shore of Amrum, many salt tolerant species can be found. 16.
