EVC 55_63 Higher Rainfall Plains Grassy Woodland
Source: Department of Environment and Primary Industries (DEPI)

This EVC consists of an open, eucalypt woodland to 15 m tall, or an Acacia/Sheoak woodland to 10 m tall. The understorey consists of a few sparse shrubs over a species-rich grassy and herbaceous ground layer. Recruitment is continuous. The cover of organic litter within this EVC is ~10%.

Interesting Fact

This EVC occupies poorly drained, fertile soils on flat or gently undulating plains at low elevations. This variant occupies areas receiving greater than 700 mm annual rainfall.

Life form percentages

View the virtual quadrat above, using the magnifying glass symbol to see more detail.

Estimate the percentage cover of each life form in the virtual quadrat, using the key and grid tool to assist. (Hint - Most of the life form percentages are multiples of 5%).

Enter the percentage cover of each life form as a whole number, e.g. 5 for 5%, in the table below.

Please note that for some quadrats the total percentage cover will be more than 100% when various life forms overlap one another.

For some quadrats the percentage of bare soil within the quadrat is noted.

You may change your estimates and resubmit if you would like to try to improve your estimation skills.

NOTE

If an estimate is correct, the life form details will change to green.

If an estimate is almost correct (within 2%), the field will change to orange.

If an estimate is not within 2% of the correct value the field will change to red.

Bryophytes/Lichens (BL)
quadrat info trigger

A broad group of small, non-vascular terrestrial plants including bryophytes (mosses, liverworts and hornworts) and lichens. These expand in height and width after rain, as they absorb moisture. They then dry out until rain falls again. Distinguished from soil crusts by the presence of a vertical structure.
