Measuring percent occurrence of objects from digital images can save time and expense
relative to conventional field measurements. However, the accuracy of image analysis had …

Research into automatic image processing of digital plot photography has increased in
recent years. However, in most studies only overall vegetation cover is estimated. In arid …

Ground cover is a key indicator of rangeland health but conventional methods for measuring
ground cover are labor intensive. Analysis of digital images has the potential to reduce …

Ground cover is a key indicator of rangeland condition and influences rangeland
management decisions, yet there have been few advances in ground-cover measurement …

Hybridization is hypothesized to promote invasiveness, but empirical tests comparing the
performance of hybrid taxa versus parental taxa in novel regions are lacking. We …

Remote sensing with unmanned airborne vehicles (UAVs) has more potential for within-
season crop management than conventional satellite imagery because:(1) pixels have very …

High‐resolution, image‐based methods can increase the speed and accuracy of ecological
monitoring while reducing monitoring costs. We evaluated the efficacy of systematic aerial …

Long-term satellite remote sensing data, when properly calibrated and validated against
ground monitoring, could provide valuable data sets for assessing climate change impacts …

Methods that are more cost-effective and objective are needed to detect important
vegetation change within acceptable error rates. The objective of this research was to …

In this study, the use of unmanned aerial vehicles (UAVs) as a quick and safe method for
monitoring biotic resources was evaluated. Vegetation cover and the amount of bare ground …
