For more than 50 years, the National Association of Soil Conservation Districts (NACD) has sponsored a national program to encourage Americans to focus on stewardship.  The program relies on locally-led conservation districts sharing and promoting stewardship and conservation activities.  While the program encourages good stewardship year round, "Stewardship Week" is officially celebrated from the last Sunday in April to the first Sunday in May. Each year, Idaho's conservation districts participate in a Poster and Speech contest, utilizing the current NACD theme.
