Main Experiment: Biological soil crust cover in runoff plots

Usage Rights

This data is Free within projects.

Dataset Abstract

The development of biological soil crusts (BSCs) has been recorded in runoff plots of sites A and B from 2013 to 2015.

Dataset Design

Photogrammetric survey within runoff plots (40 cm x 40 cm). Perpendicular images were taken with a single lens reflex camera system (Canon 350D, Tokio, Japan) and processed with the grid quadrat method (GIMP 2.8) using a digital grid overlay. Stone cover and BSC cover were separated by hue distinction.

Sites A and B, locations of runoff plots
