The Government of Ontario dropped protections for more than 100 species at risk, claiming that federal protections can fill the gap. Here are the reasons why that is misguided.

The post Winter 2025 appeared first on ON Nature Magazine.

Conservation policy usually focuses on preserving the young or endangered, but fails exceptional animals like centenarians, those remarkable individuals old even for their own species. Greenland sharks can live 400 years, lobsters over 100, and ocean quahogs 500.

Protecting centenarians is crucial. If an animal is found to live far beyond the usual lifespan of its species, I believe it should automatically be protected because of those exceptional characteristics.

These rare survivors carry irreplaceable genetic information. Just as we safeguard ancient trees, we should protect these elders as an act of responsibility, awareness, and respect. Their value lies in the fact that they are still here, and that alone should be enough to protect them.

The post Fall 2025 appeared first on ON Nature Magazine.

I appreciated the theme and content of the summer 2025 issue of ON Nature. As a long time Organic/Ecological,Regenerative farmer I was pleased to see Ray Ford’s article on “The Costs of Modern Agriculture” on page 16.

We need to make farming and ranching part of the solution rather than a big part of the problem. Regenerative farming and ranching practices can actually take carbon out of the air and sequester it by increasing soil organic matter while improving soil health, water infiltration, nutrient density of food and increasing biodiversity below and above the soil.

Two organizations that are working to help farmers in this regard are Farmers for Climate Solutions and the Ecological Farmers Association of Ontario.

Thank you for an informative, thoughtful and at times even hopeful issue on Ontario Nature and the efforts to protect and restore it.

The post Modern Farms Impact on Nature appeared first on ON Nature Magazine.

Thank you to all at ON Nature magazine for an always informative and visually engaging publication. I read every issue from cover to cover.

I read Ian Coutts’ article, “The Dirt on Gardens” with some interest and concern. It might encourage others with naturalized gardens to learn that the City of London has recently updated its Yard and Lot Maintenance By-Law to provide clearer guidelines for gardens that support biodiversity, including pollinator, food and native plant gardens.

These changes were largely prompted by the work of Brendon Samuels, Chair of the city’s Environmental Stewardship and Action Community Advisory Committee. The approach was informed by the Bylaws for Biodiversity project of the Ecological Design Lab. The project (available at ecologicaldesignlab.ca/by-laws-for-biodiversity) provides free practical tools to support similar advocacy efforts in other jurisdictions.

After receiving an order to comply with the city’s yard maintenance by-law in 2023, Brendon set about to determine how to achieve compliance with the by-law. The concerns he and his committee raised about the existing by-law resulted in a “housekeeping” update of the by-law by city staff. The revised by-law was enacted in March 2024 and provides much-needed clarity for both property owners and people who wish to file a complaint. https://london.ca/yard-lot-maintenance-law.

According to the city website, the by-law requires property owners to keep their land safe for the public, appropriately store and remove refuse, remove and stop the growth of prohibited plants, and remove graffiti from buildings and structures, among other things. The city’s website emphasizes that the by-law is not intended to manage the aesthetics of gardens, especially where vegetative growth or a garden has been intentionally cultivated. The city’s Climate Emergency Action Plan encourages the planting and maintenance of diverse, resilient, native plant species and gardens to help slow the effects of climate change.

In addition, Brendon and his committee have made “Nature Lives Here” lawn signs available to the public. The signs are meant to educate and reduce conflict with neighbours who may object to the appearance of naturalized properties.

May other municipalities follow this example!
