Tree-Planting Workshop--”ReLeaf Orange County,” part of a statewide campaign to plant 20 million trees by the year 2000, will hold a public workshop Wednesday in Anaheim.

Andy and Katie Lipkis of the Los Angeles TreePeople and Isabel Wade, director of California ReLeaf, are scheduled to speak at the 7 p.m. program.

California ReLeaf is a project of the Trust for Public Land, a nonprofit land conservation organization based in San Francisco. The tree-planting campaign was created in the hopes that the new trees planted during the next decade will ease the effects of global warming.

Individuals and groups who want to join the effort in Orange County are invited to attend the workshop at the Brookhurst Community Center, 2271 W. Crescent Ave., Anaheim. Call (714) 725-0323 for more information.

Gardening Workshop--New drought-resistant methods of watering gardens will be demonstrated Saturday at the Demonstration Organic Garden at the Fullerton Arboretum, Associated Road and Yorba Linda Boulevard. A tour of the experimental garden and a discussion of overhead sprinkling, soaker hoses and drip irrigation systems are also planned at the meeting of the California Organic Gardening Club.

Drought-resistant gardens, which utilize plants that need little water and maximize benefits from the water that is used, have become a hot topic as homeowners and local governments try to find ways to conserve. With the region in the midst of a four-year drought, many cities have asked residents to voluntarily cut back water usage by at least 10%, with a warning that such cutbacks could become mandatory in the future. Other cities are considering policies that would require drought-resistant landscaping at new developments.

The program will be held from 10 a.m. to noon and is open to the public. Information: (714) 637-9734 or (714) 969-2346.

Festival--The American Oceans Campaign will have an environmental festival from 11 a.m. to 5 p.m. next Sunday at Lido Marina Village in Newport Beach. Activities will include a seafood chowder cook-off, speakers on environmental topics, live entertainment and a sportswear fashion show. The festival is part of a two-day event called STOP (Stop Toxic Ocean Pollution), which includes a celebrity golf tournament June 25 at the Tustin Ranch Golf Club. Information: (714) 723-0544.
