Definition - What does Flora mean?
Flora refers to all plant-life that occurs within a habitat or region. Usually, it refers to naturally occurring plants rather than those that have been introduced by man. Occasionally, the term also embraces the species of bacteria and fungi that occur.
Safeopedia explains Flora
Plant life is the basis of all life occurring within an ecosystem. Should the composition of the flora change, the ecosystem will no longer be able to support the animal and insect life that should occur in the region and the ecosystem, in turn, becomes disrupted. In a similar way, gut flora, which are naturally occurring bacteria within the body, are responsible for balancing digestive function and a disruption will cause digestive problems.
