Toronto Field Naturalists

Toronto Field Naturalists This charitable, non-profit organization has been promoting a love of nature in Toronto since 1923.

Toronto Field Naturalists connects people with nature in the Toronto area. We help people understand, enjoy, and protect Toronto’s green spaces and the species that inhabit them. The TFN is a volunteer-run non-profit and a member of the province-wide Ontario Nature network of naturalist organizations. We share the desire to deepen understanding of, and appreciation for, the natural spaces and spec

ies needed for health and well-being. We do this through our website, newsletter, public lecture series, outreach programs, stewardship of 178 hectares of nature reserves, more than 150 public nature walks each year, and advocacy for policies and programs consistent with our mission.

When you walk off trail you could trample the less conspicuous first year plants which may just have a single small leaf. Walking off trail also compacts the soil which affects the life cycle of spring ephemerals.

Something to watch out for.

The invasive spotted lanternfly (SLF) is a growing concern for Ontario’s horticulture and natural areas. While there are no confirmed established populations in Ontario, it has become a significant issue in nearby U.S. states. Staying aware and knowing what to look for can help support early detection. It's important to be on the lookout for egg masses and nymphs in the wild and all stages of life on imports.

If you spot SLF at any stage, remember:
🔍 SPOT IT Learn the signs and stay alert in outdoor spaces and on transported items.
📸 SNAP IT Take clear photos to help with identification and reporting.
🫙 CATCH IT If possible, safely contain or destroy the insect or egg mass.
📢 REPORT IT Report sightings to the Canadian Food Inspection Agency.
