Bio-calendar October



True Spring

(September to October).

True Spring is over by the end of October as the season begins to change to an Early Summer from November.

During October many plants are still in their flowering cycle and animals are in the process of caring for their offspring. The warming sun has awakened the reptiles and mating is underway. Brown elver eels begin their upstream migration from estuaries into rivers and streams. Migratory shorebirds arrive from the Northern Hemisphere.

The following list provides an insight to various life stages for some of the native plants and animals in Victoria during October, bearing in mind there will be some variation across different bioregions.  Please contact SWIFFT so we can add to the list.
