A series of experiments was conducted to study the effect of hedgerows on airborne pollen concentrations. Sampling of tree pollens and ragweed pollen from distant upwind sources was conducted with rotoslide samplers mounted at three heights and sixteen locations both upwind and downwind of a dense arbor-vitae hedge and a porous deciduous hedge. A pronounced concentration maximum was found in the cavity region downwind of each hedge.
