RESULTS
Visitor groups contacted
At Joshua Tree NP, 767 visitor groups were contacted and 700 of these groups (91%) accepted questionnaires. Questionnaires were completed and returned by 525 visitor groups, resulting in a 75% response rate for this study.
Table 2 compares age and group size information collected from the total sample of visitors, who participated, with age and group size of visitors who actually returned questionnaires. Based on the variables of respondent age and visitor group size, non-response bias was judged to be insignificant.

Fifty-three percent of visitor groups were made up of family members and 24% were with friends (see Figure 2). “Other” group types included romantic interest partners, rock climbing groups, hiking clubs, motorcycle club (AMCA), botanical study groups, Boy Scouts, Desert Institute, and home schooling groups.
Forty-seven percent of the visitors were in the 26-50 age group and 19% were 15 years or younger (see Figure 3). Over one-half of visitors (52%) were male and 48% were female (see Figure 4). Forty-nine percent of visitors reported that this was their first time visiting Joshua Tree NP, 16% had visited the park between three and five times, 14% had visited twice, and 16% visited nine or more times in their lifetime (see Figure 5).
