Laser-imaging bird habitats

A paper out in the October issue of Ecological Applications puts forth a new use for light detection and ranging technology, or LiDAR: the prediction of bird habitats.

LiDAR technology uses laser imaging techniques to develop maps of forest vegetation structure by sending laser beams from aircrafts that fly over a study area. In this case, the scientists sampled the Cosumnes River Preserve in central California.  They then can use known data about bird habitat preferences to predict the diversity and abundance of birds in the area.  Said Joshua Viers, a researcher at UC Davis:

By combining this advanced imaging technology with traditional field research, we are able to measure and predict ecosystem components in unprecedented ways. Not only can we provide managers with very detailed information about ecosystem services such as carbon storage and its associated biodiversity, but we can do so over very large areas.

Not to mention saving graduate students months of painstaking vegetation sampling.
