On the other hand, if the surface temperature of the snow is much colder than the ground level temperature, ice crystals form and weaken the snowpack.
To do this, scientists dig a snow pit – a deep hole in the snowpack that goes all the way down to ground level and is several meters wide.
Figure 7 shows the pattern of ground level land uses in the study area.
As a precaution against (rare) flooding, the main ground level should be kept at its present safe and dry elevation.
All bats were collected using mist nets erected at ground level.
No species was trapped most commonly at ground level.
However, all adult trapping has been conducted at or near ground level.
To sample bats, we set five 6-m mist nets at ground level in the forest.
