More than 500 horses and burros have been rescued by Equine Voices Rescue & Sanctuary in Southern Arizona since the nonprofit started in 2004.
Yet its work is far from done - the need grows daily, said Karen Pomroy, the group's founder and president.
Every day, the nonprofit receives two to four calls and emails from people seeking help for horses in need of food, shelter and care.
Equine Voices is at capacity at its 10-acre sanctuary in Amado, she said. The nonprofit is trying to raise $65,000 to buy five adjacent acres to make room for more horses.
"It's a very challenging time and it has been for the last couple of years - that's why this fundraiser is so important," she said, referring to "A Very Special Horse Event; Building a Community of Compassion."
The event, now in its ninth year, will be held 11:30 a.m. to 3:30 p.m. Saturday at Brandi Fenton Memorial Park, 3482 E. River Road, which has a horse arena.
Admission is $5 and includes one raffle ticket. Children 6 years old and under are free. More details at www.equinevoices.org
The event, which will feature several rescued horses and demonstrations, is also about making people aware that so many horses need rescue.
Carol Grubb of Eclectic Equine will demonstrate natural horsemanship techniques and talk about the plight of horses today and why so many need rescuing.
There will also be a live dessert auction, a silent auction, and raffles , along with food, clothing, art and jewelry and tack for sale.
The Amber Norgaard Band will also perform.
"It's an event for everyone - not just horse people," Pomroy said.
