Ground vegetation influences habitat selection and provides critical resources for survival and reproduction of animals. Researchers often employ visual methods to estimate ground cover, but these approaches may be prone to observer bias. We therefore evaluated a method using digital photographs of vegetation to objectively quantify percent ground cover of grasses, forbs, shrubs, litter, and bare ground within 90 plots of 2m2. We carried out object-based image analysis, using a software program…

Can Plot-Level Photographs Accurately Estimate Tundra Vegetation Cover in Northern Alaska?

Plot-level photography is an attractive time-saving alternative to field measurements for vegetation monitoring. However, widespread adoption of this technique relies on efficient workflows for

Digital Photograph Analysis for Measuring Percent Plant Cover in the Arctic

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

Using photographic image analysis to assess ground cover: a case study of forest road cutbanks

A photographic image analysis method was developed and applied to assess percent ground cover along an entire cutbank of a cut-and-fill haul road in the Monongahela National Forest in Tucker County, West Virginia and proved to be a useful tool for land managers who require a more repeatable quantification of ground cover than is possible through visual assessments.

A Technique for Estimating Rangeland Canopy-Gap Size Distributions From High-Resolution Digital Imagery

Abstract The amount and distribution of gaps in vegetation canopy is a useful indicator of multiple ecosystem processes and functions. In this paper, we describe a semiautomated approach for

A Comparison of Visual and Photographic Estimates of Weed Biomass and Weed Control1

Abstract: The objective of this study was to compare the consistency and accuracy of visually estimated weed biomass and weed control data to data obtained through image analysis. Weed biomass and


The biases of different observers for a particular species and quadrat size were sufficiently consistent that the use of mean bias correction factors brought about clear gains in the precision of cover estimates for most species.

Scale-dependent variation in visual estimates of grassland plant cover

Abstract Plant cover was visually estimated by five observers, independent of each other, in a species-rich grassland in the Bílé Karpaty Mts., southeastern Czech Republic, in seven plots ranging

Effects of sampling teams and estimation methods on the assessment of plant cover

Abstract We evaluated variability in cover estimation data obtained by (1) two sampling teams who double sampled plots and (2) one team that used two methods (line intercepts and visual estimation of

Comparison of rangeland vegetation sampling techniques in the Central Grasslands

Maintaining native plant diversity, detecting exotic species, and monitoring rare species are becoming important objectives in rangeland conservation. Four rangeland vegetation sampling techniques


SUMMARY (1) The magnitude of changes required to detect air pollution effects was determined by an error analysis of visual estimates of plant cover in a Pinus contorta var. latifolia stand in

Relationships of the Error Associated with Ocular Estimation and Actual Total Cover

The relationship between the error associated with the ocular estimation of cover and the magnitude of actual cover was ewamined by estimation of artificially constructed images of known cover under laboratory conditions by controlling for the aforementioned factors through the use of an artificial population of two-dimensional images ofknown coverage.

Habitat Structure, Patchiness, and Avian Communities in North American Steppe Vegetation: A Multivariate Analysis

This work examined the effect of variation in several measures of both horizontal and vertical patchiness in vegetation distribution on bird distribution and abundance, then integrated these measures into a smaller subset of variables using Principal Component Analysis (PCA).

Sampling Techniques Influence Understory Plant Trajectories After Restoration: An Example from Ponderosa Pine Restoration

Abstract Although there is no one correct technique for sampling vegetation, the sampling design chosen may greatly influence the conclusions researchers can draw from restoration treatments.


Local biotic interactions and recruitment dynamics jointly determined diversity, species composition, and species abundances in these native grassland communities, suggesting that recruitment limitation may be more important, even on a local scale, than often recognized.
