I need to set up a recording sheet to determine the difference in microhabitats.

Which are the key parameters that I should categories when I want top distinguish different microhabitats. I know that I need to look at the organics, the grain size of the substrate, the overall composition of the soil, the humidity and the shadowing of the area. Are there more parameters that I should look at?

Or are there any publications in which I can find such recording sheets?

Thanks in advance for all answers!
