They may be skilled people seeking to learn new skills, or people who come to you without any specific training. Volunteers come with different backgrounds, abilities and desires to interact with other people. Some may prefer working alone. Others may prefer an opportunity to work with other people, or look at volunteering as a way to make new friends with similar interests. Socializing among volunteers and between volunteers and staff is an inherent part of any volunteer program.
Groups constitute a special category of volunteers.
Through group involvement, projects requiring large numbers of people, such as the maintenance of a long segment of trail or the handling of a special event, can be accomplished. Special-interest groups can be recruited for projects that relate to their interest.
