My challenge for you today is to estimate how many daisies there are in your lawn using sampling.

To find out how take a look at my you tube video.

What you will need:

Four same size sticks or rulers

A Hoop

A cut out paper footprint.

What to do:

Take your sample size, either a square made out of the 4 same size sticks or rulers, hoop or footprint and place it on the lawn.

Look inside and see what plants are growing there. Choose one to count which is found all over your lawn but not the grass itself. Daisies or buttercups are good.

Then count how many of that flower there is inside your sample. If there is too many to count then estimate the proportion of your sample which is covered by the flowers. See my you tube video for more details.

Write down this number. Then repeat 9 more times all over your garden until you have 10 numbers for the amount of daisies.

Calculate the mean average by totalling up the number of daisies from all 10 samples and dividing it by 10. This is the mean average for the number of daisies for your sample size in your lawn. You can now scale that up to the whole lawn by estimating how many of your sample areas would fit in your whole lawn. If you estimate that 100 sample area would fit in your lawn then multiply your mean average by 100 to get a total number of daisies for your whole lawn.

I would love to hear your results and we can see how all your results compare so please Tweet your answers #Naturedays @DawnNaturedays or post on the Nature Days facebook page.
