Building Biodiversity With ‘Pollinator Strips’

Project Background

As century-old prairie farms are bought up, traditional farmyards with their shelter belts and trees are being torn down and the surrounding bush cleared. These traditional farmscapes, with their wealth of biodiversity, once provided the ideal setting for bees and beekeepers.

The loss of biodiversity has had other impacts as well, including reduced seed set, loss of soil quality, and increased pest pressure.

Prairie farmers are beginning to experiment with a practice known as ‘pollinator strips’. This technique not only enhances biodiversity, but it can also act as a ‘buffer zone’ to protect water bodies and increase soil moisture – an important consideration as North American summers become hotter and drier.

What Is a Pollinator Strip?

Pollinator strips are purposely designed areas of vegetation located on the marginal land or wetlands of a farm. Their function is to provide habitats for pollinators and to restore local biodiversity.

What Kind of Seed Blend Might Be Used in a Pollinator Strip?

Avena used a pollinator seed blend developed by plant scientists at the University of Manitoba. The TG Pollinator Blend contains 11 varieties of plants, including annuals, perennials and biennials.

Throughout the growing season the flowers attract bees and birds, as well as nourishing beneficial insects. They also assist with pollination and yield in the adjacent crop.

Alfalfa and clover in the blend have the additional property of extracting nitrogen from the air and ‘fixing’ it in the soil.

Keeping roots alive in the soil year-round prevents soil erosion, improves water quality in neighboring waterways, and sequesters carbon.

How Can You Measure the Impact of a Pollinator Strip?

A variety of tools are available for measuring and quantifying the benefit of pollinator strips. Metrics typically used include the number (and variety) of insects, the soil carbon content, and the soil’s microbiome. Other inputs come from water infiltration tests, yield analysis and imaging tests.

Where’s the Buzz?

Many pollinator species are threatened.

The ‘Bee Tool of North America’ is a web-based application that was developed to monitor bee populations across North America.

Linking Across the Value Chain: Pollinator Strip Impact Projects

Avena has established two-year Pollinator Strip Impact Projects. These initiatives enable a commercial customer to support a farm in implementing a field-scale pollinator strip. Reports and pictures are provided from pre-seeding to post-harvest, allowing companies to share information with their customers. Farm to Fork in action!
