Park Place--The Rancho Mission Viejo Land Conservancy is looking for 300 to 400 people to participate in the “March for Parks” on April 19, from 9 a.m. to 2 p.m. The nationwide event was organized in 1990 to celebrate Earth Day, which will include more than 1,000 marches this year. At the conservancy, funds will go for environmental education programs and for tools to help maintain the trails. Marchers will be led in small groups by docents through the 1,200-acre reserve. The day’s events include a picnic, displays by environmental groups and children’s activities.

Marchers should collect pledges and bring contributions April 19. Prizes will be awarded for the top fund-raisers. Volunteers are also needed for registration, traffic control, setting up signs and booths, food preparation and cleanup. Information and registration: Laura Cohen, (714) 489-9778.
