  journal={Arboriculture \& Urban Forestry},
The ease of ignition of 13 commonly used landscape mulches was evaluated. Mulches have different ignition potentials based on several factors, including the length of exposure to heat and to the ignition source. Some materials ignited more frequently when exposed to a lit propane torch for 15 seconds. The most to least commonly ignited materials were ground rubber, pine straw, oat straw, shredded hardwood bark, shredded cypress bark, recycled pallets, 2.5 to 5 cm pine bark nuggets, 1.3 to 2.5…

Development of Test Methods for Assessing the Fire Hazards of Landscaping Mulch
Landscape mulches are widely used adjacent to buildings and represent a potential fire threat to the building. To date, relatively limited research has been conducted to characterize the ignition and
Impact of Mulches on Landscape Plants and the Environment — A Review
Mulches provide aesthetic, economic and environmental benefits to urban landscapes. Mulching is especially useful in the establishment of trees in landscapes that receive minimal care, such as
PROJECT TITLE: Use of Mulch as Daily and Intermediate Cover for Landfills
Management of yard waste is a significant challenge in the US, where in 2005 13.1% of the 245 million tons of municipal solid waste was reported to be yard waste. Approximately 61.9% of yard waste is

Mulching Techniques to Conserve the Soil Water and Advance the Crop Production - A Review
The necessity to increase the production of food grains and enhances the quality of surrounding environment has leaded to find the materials to control or regulate the water and wind erosion.
Introduction Regardless of how horrible and devastating wildland fires are portrayed by the media, they are a natural disturbance that many native ecosystems depend on for regeneration. As the
Assessing the exposure of the built environment to potential ignition sources generated from vegetative fuel
We assessed the exposure of the built environment to potential ignition sources generated from vegetative fuel for four communities in the province of Alberta, Canada. Ignition processes generated by


The multiple benefits of organic mulches in landscape environments are well documented (3,7). The few problems associated with mulch use can be minimized or avoided with proper management. For
