According to landuse data from 2000, 9.5% of the county is 'orchards, bush fruit, vineyards, or ornamental horticulture' (orange on the map). Other agriculture (e.g., row crops) make up an additional 9.8% of the county (green on the map). In all 19.3% of the county is dedicated to agricultural land uses, with the bulk of the orchards and vineyards located further north in the county where proximity to temperature-moderating open water is greater.
