“Balancing the need to effectively manage weeds and pests in parks, the mandate to protect and conserve valuable natural resources and the demand for well-manicured recreational areas can be a big challenge for land managers.
The negative environmental and human health impacts of synthetic fertilizers, herbicides and pesticides have been widely documented and some park agencies are seeking and testing new landscape management methods to strike a balance that would satisfy park users and managers.”
