'''BOTANY:''' The flora of Santa Catalina Island includes about 431 native taxa, 37 California Islands endemics, and 203 non-native taxa for a total of 634 species. Over 160 plants on Catalina Island are considered rare. The term “rare” is defined as any species that has 3 or less populations on the island. Not all of the rare plants on Catalina are rare on the mainland. Our unique habitats as well as the populations of introduced deer and bison create a very different environment than on the mainland and even other Channel Islands.

BOTANY: The flora of Santa Catalina Island includes about 431 native taxa, 37 California Islands endemics, and 203 non-native taxa for a total of 634 species. Over 160 plants on Catalina Island are considered rare. The term “rare” is defined as any species that has 3 or less populations on the island. Not all of the rare plants on Catalina are rare on the mainland. Our unique habitats as well as the populations of introduced deer and bison create a very different environment than on the mainland and even other Channel Islands. This can cause species that are common on the mainland to be rare on Catalina. Some of the noteworthy rare species are listed below:

  • Aphanisma (Aphanisma blitoides)
  • California dissanthelium (Dissanthelium californicum)
  • California groundsel (Senecio aphanactis)
  • Catalina Island monkeyflower (Mimulus traskiae)
