The main reason for the lack of trees on the Western Plains Grassland in Victoria is the presence of heavy clay soils that are poorly drained, readily becoming water-logged in winter or exceedingly dry in summer. Water-logged soils tend to favour fibrous rooting plants, such as grassland species, rather than tap-rooting plants such as trees. Winters are cold and often frosty, with a mean maximum in the coldest month of 10

this area is a hotspot of threatened biodiversity because grazing has changed the species composition.

|
|
this biome occurs across a large and diverse geographical area.

with a scarcity of trees, resource partitioning would be unlikely to occur in the grassland.

abiotic factors including climate and substrate can be used to describe and classify environments.

Explanation:
Detailed explanation-1: -The low precipitation rates are enough to nourish grasses but not enough for a forest of trees.
Detailed explanation-2: -Because of the low annual precipitation, temperate grasslands have very few trees.
Detailed explanation-3: -Each different species of grass grows best in a particular grassland environment (determined by temperature, rainfall, and soil conditions). The seasonal drought, occasional fires, and grazing by large mammals all prevent woody shrubs and trees from invading and becoming established.
