Soil properties limiting vegetation establishment along roadsides

Natural Product Herbicides for Control of Annual Vegetation Along Roadsides

Natural product herbicides for vegetation control are being considered as alternatives to synthetic herbicides by many public agencies. Studies were conducted along roadsides at the Hopland Research and Extension Center (HREC) in 2001 and 2002 and on California State Route 29 (SR29) in 2002 to evaluate acetic acid, pine oil, and plant essentials compared with glyphosate for control of herbaceou...

Identifying and Addressing Soil Property Issues Affecting Roadside Vegetation Establishment

Characterization of Biophysical Vegetation - Soil Dynamics along an Eco-climatic Brazilian Transect with Modis Vegetation Indices

Field measurements were conducted on 10 June through 21 July 2002 to collect biophysical data in support of MODIS validation studies. Leaf Area Index (LAI), Plant Area Index (PAI), Absorbed Photosynthetically Active Radiation (fAPAR), biomass, cover components, site characterization and soil characterization were measured. The study areas extended over an eco-climatic transect, from the cerrado...

Predicting species distributions from samples collected along roadsides.

Predictive models of species distributions are typically developed with data collected along roads. Roadside sampling may provide a biased (nonrandom) sample; however, it is currently unknown whether roadside sampling limits the accuracy of predictions generated by species distribution models. We tested whether roadside sampling affects the accuracy of predictions generated by species distribut...
