Other macropods:
* Wallaroos: Smaller relatives of kangaroos, often sharing similar grazing areas.
* Red-necked Wallaby: Another type of kangaroo, often found in the same areas as eastern grey kangaroos.
Other herbivores:
* Sheep and cattle: Introduced grazing animals can compete with kangaroos for grass, especially in areas where they have been overgrazed.
* Rabbits: A highly adaptable species that can compete for food and water with kangaroos.
* Goats: Introduced goats can also be a source of competition, especially in areas where they have become feral.
* Native herbivores: Other native herbivores like wombats, echidnas, and some bird species may also compete with kangaroos for specific types of food.
The extent of competition depends on factors like the availability of food, the density of populations, and the specific species involved. For example, in areas with ample rainfall and lush vegetation, competition may be less intense. However, in drier regions where food is scarce, competition can become a significant factor in the survival of kangaroos and other herbivores.
