The San Dimas Equestrian Commission, in its continuing mission to offer environmentally attractive equestrian and multi-use trails in the city, will conduct a clean-up day for the trails at Horsethief Canyon Park and Sycamore Canyon on Saturday.

Teenage and adult volunteers are needed to make the clean-up most effective, said commission chairwoman Rebecca Pike and San Dimas Assistant City Manager Ken Duran, the City Hall liaison to the commission. Volunteers must call 909-394-6214 by 4 p.m. Friday, to sign up and enable the commission to determine the number of volunteers taking part in the luncheon following the trail work.

Commission chairwoman Rebecca Pike, vice chairwoman Claudia Cook and members Sonya Sevier, Marca DeMonaco and Yvette Picconi will prepare the burger and sides lunch.

Volunteers check-in at 8:30 a.m. at Horsethief Canyon Park's Picnic Pavilion on Saturday. The work is from 9 a.m. to noon.

Trash is not a major problem on the city-maintained trails, Pike said, "but during rainy seasons rocks roll onto the trails. We'll be removing rocks, abating weeds and spreading decomposed granite on the trails. This latter effort lessens the amount of mud on the trails and better controls the growth of weeds. "

"The Equestrian Commission was formed in the 1980s to advise the City Council on equestrian-related matters, including trails, equestrian-zoned properties and equestrian centers. Each commissioner serves 2-year terms and is limited to three terms. "

Pike, a commissioner for four years, said white railed fences mark equestrian trails adjacent to city streets. The city system extends into the foothills and canyons on the north end of San Dimas, but not into the Angeles National Forest.

Ann Garcia, San Dimas Community Development Department administrative aide, prepared the colorful trails and bikeways guide available at City Hall and the privately owned Oak Valley and San Dimas equestrian centers, the city-owned Sycamore Canyon center and Bonelli Park. The guide includes access guidelines which better "ensure public safety, resource protection and an enjoyable experience for everyone using the trails," Garcia noted.

The open space areas along many of the trails "provide permanent sanctuaries for native wildlife and vegetation," Garcia continued. "As pressures from the expanding human population increase, the preserves become even more important as refuges for wildlife. Nesting birds, stream life, reptiles and mammals depend on the protection of open space. "

Duran and Pike said most of the local trails are multiple-use, allowing bicyclists, hikers, joggers and equestrians to use them. Dog walkers, photographers, bird watchers and nature walkers also use the trails.

"Trail etiquette also requires dogs to be on leashes at all times and dog owners must pick up after their dogs. No alcohol consumption is allowed. Smoking is not permitted in the wilderness area or public parks due to high fire risks. Motorized vehicles are prohibited. Additionally, a no-littering policy requires trail users to "carry out what they carry in," said Garcia.
