Shelterbelt plantings in Iceland in 1957-62 amounted to 4885 m., or 20, 395 m. of individual rows. Details are given of choice of species, lay-out of belts, site preparation, planting methods, protection, tending, and effect on crop yields. Results are considered promising and further plantings are ...

A review of trials since 1884; work was intermittent through lack of funds and personnel until 1967. Conifers and broadleaves that have been tried are listed with comments on their suitability.
