Fullerton Arboretum Desert Collection Enhancement

Desert Collection Enhancement

The October “Month of Giving” has started, and we need your help to enhance our Desert Collection at Fullerton Arboretum. There are currently no clear pathways in our Desert Collection, which has resulted in habitat-destructing social trails. That’s why this ROCK-tober, we are working on building rock-bordered trails throughout the area. This will also help to protect the plants, control soil erosion and prevent the habitat destruction of ground-nesting bees. Your donation will support this important project.

Thanks to a generous donor we have $30,000 in matching gift funds available. When you make a gift, it will be matched dollar-for-dollar through $1,000. Help us reach our goal of $10,000!
