Why Biodiversity Matters
Biodiversity is the variety of life in the world or in a particular habitat. It is essential to maintaining ecosystem health and resilience. When ecosystems are diverse, they can better withstand climate change and its impacts.
Consequences of Losing Biodiversity
The loss of biodiversity is a critical issue facing our planet today. According to the Intergovernmental Science-Policy Platform on Biodiversity and Ecosystem Services (IPBES), human activities are driving species extinction at a rate estimated to be 100 to 1,000 times higher than the natural rate. This is largely due to climate change, habitat destruction, pollution, and overexploitation of resources.
Climate Change and Biodiversity
Climate change is a major driver of biodiversity loss. Rising temperatures, changing precipitation patterns, and increased frequency of extreme weather events are altering ecosystems and disrupting the delicate balance of nature. This can lead to the loss of habitats, extinction of species, and disruption of ecosystem services.
Supporting Biodiversity in Your Garden
There are many ways to support biodiversity in your garden. Here are some simple actions you can take:
- Use alternatives to pesticides
- Leave the leaves
- Prioritize pollinator-attractive plants
- Make your garden safe for birds
- Advocate for biodiversity
Use Alternatives to Pesticides
Pesticides can harm beneficial insects and the environment. Instead, use natural alternatives like biopesticides, horticultural oils, and insecticidal soaps. These can be just as effective as chemical pesticides.
- Attract predatory insects and wildlife
- Use DIY pesticides like sea salt spray, water-vinegar mixtures, and coffee grounds
Leave the Leaves
Decomposing plant litter, like fallen dead leaves, tree bark, needles, and twigs, is essential for maintaining soil health, nutrient cycling, and biodiversity. By leaving the leaves in your garden, you support the variety of species that overwinter in them.
Prioritize Pollinator-Attractive Plants
Pollinators like bees and butterflies are crucial for ecosystem health. Prioritize native plants and herbs, which promote a resilient ecosystem and help natives out-compete invasive species.
Make Your Garden Safe for Birds
Birds contribute to healthy ecosystems by pollinating plants, dispersing seeds, and preying on insects. To support biodiversity, adopt bird-safe gardening practices like organic gardening, keeping cats indoors, removing potential entanglement hazards, and using bird-collision prevention markers.
Advocate for Biodiversity
Although there’s a growing movement toward more biodiversity-supporting practices, outdated municipal bylaws and enforcement policies continue to limit the potential of habitat gardens. Advocate for biodiversity by supporting local organizations and promoting sustainable gardening practices.
