Posted September 16, 2018 07:59:55 A new study suggests that the use of charcoal as a cooking method is a factor in the growth of invasive species in barbecue grilling systems.
Researchers from the University of Adelaide, the University’s Department of Environmental Sciences, and the University and College of Art and Design have examined the impacts of charcoal use on two major types of native grasses: native and exotic grasses.
The researchers found that native grass and exotic woody plants were both adversely affected by charcoal use.
The researchers say they hope the study will help reduce the risk of invasive grasses becoming established in backyard barbecue gridded areas.
The study, published in the Journal of Applied Ecology, was conducted in collaboration with Australian and New Zealand Government scientists.
It found that the introduction of exotic grass species to backyard barbecue grill systems could have a significant impact on the abundance of native and native-derived species.
The scientists found that introduced exotic species caused the abundance and diversity of native species to decline.
The results of the study were published in a recent issue of the journal Ecology.
Researchers say that native and introduced species in backyard griddings should be considered a trade-off.
“We need to ensure that we get the benefits of native ecosystem services for all our guests, but also protect native species,” said Dr. David R. Schumacher, one of the authors of the research.
“Native species are more resilient to changes in their environment than introduced species and we need to consider the trade-offs that can occur in order to ensure we are maximising the benefits for guests,” he said.
Schumacher said the study’s results are important because it shows that charcoal-based grilling may not be the best solution to reduce the amount of invasive plants in backyard grill systems.
“If we’re going to be using charcoal as part of a grilling system, we should consider the benefits to native grass species and exotic species, as well as the benefits that can be gained from the use and development of charcoal,” he added.
“It’s a matter of balancing all these benefits.”
