• wild state such as wild rice, cattails, or certain forest products commonly associated
with wetland, however, They should be included in the Weiland category. Similarly,
when wetlands are drained for agricultural purposes, they should be included in the
Agricultural Land category. W hen such drainage enterprises fall into disuse and if
wetland vegetation is reestablished, the land reverts to the Wetland category.
The Level II categories of Agricultural Land are: Cropland and Pasture;
Orchards, Groves, Vineyards, Nurseries, and Ornamental Horticultural Areas; Con-
fined Feeding Operations; and Other Agricultural Land.
21. Cropland and Pasture
The several components of Cropland and Pasture now used for agricultural
statistics include: cropland harvested, including bush fruits; cultivated summer-
fallow and idle cropland; land on which crop foilure occurs; cropland in soil-
improvement grasses and legumes; cropland used only for pasture in rotation with
crops; and pasture on land more or less permanently used for that purpose. From
imagery alone, it generally is not possible to make a distinction between Cropland
• and Pasture with a high degree of accuracy and uniformity, let alone a distinction

Moreover, some of the components listed represent the condition of the land at the
end of the growing season and will not apply exactly to imagery taken at other times
of the year. They will, however, be a guide to identification of Cropland and
Pasture. Brushlond in the Eastern States, typically used to some extent for pasturing
cattle, is included in the Shrub-Brushlond Rangeland category since the grazing
activity is usually not discernible on remote sensor imagery appropriate to Levels I
and II. This activity possibly might be distinguished on low-altitude imagery. Such
grozing octivities generally occur on land where crop production or intensive
pasturing has ceased, for any of a variety of reasons, and which has grown up in
brush. Such brushlands often are used for grazing, som ewhaT analogous to The
extensive use of rangelands in the West.
C ertain factors vary throughout the United States, and this variability also must
be recognized; field size depends on topography, soil types, sizes of farms, kinds of
crops and pastures, capital investment, labor availability, and other conditions.
Irrigated land in the Western States is recognized easily in contrast to Rangeland, but
in the Eastern States, irrigation by use of overhead sprinklers generally cannot be
. detected from imagery unless distinctive circular patterns ore created. Drainage or
