Cases

Fungal mycelium networks can break down petroleum hydrocarbons, heavy metals, and synthetic chemicals in contaminated soils. Some cities have begun small-scale mycoremediation pilots in public parks, but advocates argue the technology is mature enough to mandate as standard park management practice. Opponents cite variable efficacy across soil types, the need for ongoing monitoring, and potential ecological trade-offs with native fungal communities. Should municipalities mandate fungal bioremediation as a standard practice, or keep it as a pilot program until more data is available?

Urban foraging is a growing practice in Portland, but current park rules are unclear and inconsistently enforced. This case asks the community to weigh in on whether Portland Parks & Recreation should adopt a formal policy that permits responsible, culturally-informed foraging of invasive species and abundant native plants — with clear guidelines on harvest limits, species protection, and Indigenous consultation. The outcome would inform a proposal to be presented at the next City Council parks hearing.
