Biodiversity is short for biological diversity and embraces all plants, animals, insects, pollinators, etc. It recognizes the importance of genetic variation within species on which survival and evolution depend. Biodiversity is defined as species richness or the number of species in an area and should also include structural complexity — the assortment and variety of plant growth habits and structures in the garden. If your garden has a high level of biodiversity, the garden will be more stable, resilient, and adaptable. There should be more beneficial insects and pollinators, less disease pressure, better soil nutrients, and better fruit/veggie production. There are many ways to increase biodiversity:

  • Incorporate companion planting which is using plant partnerships to improve the overall ecosystem of the garden and creating a well-balanced environment in which all organisms thrive. Pair plants so that one provides a benefit to the other.
  • Choose open pollinated seeds or plants. Open pollinated plants are more genetically diverse. While hybrids have their benefits, as stated in this Seed Savers Exchange blog, open varieties conserve genetic diversity and prevent the loss of unique varieties.

I will be adding other methods to increase biodiversity in the garden to this page. If you know of any or of any resources about biodiversity, please comment or send me an email.
