Vegetation transect surveys were conducted in Manhattan Gulch in spring 2009. Simple line transect measurements can be used to estimate residue coverage. The mountain plover has had its nests counted through the drive transect method. Exposed mineral soil covered only 0.3% of the observed transect area. However, a transect parallel to Earth's surface of a dome features concentric rings of strata. In the Yosemite transect, no significant change in avian species abundance was found. The concept of the transect was borrowed from ecology. Major oil and natural gas pipelines transect Aktobe and the surrounding region. The laceration may completely transect the airway or it may go only partway around. It is less effective than other methods, such as the Belt Transect. Up to of material can be in motion per transect per hour.
