The tree responds to the chemicals from the wasp and quickly produces an apple-like matter that the wasp larva consumes until it pupates into an adult wasp. Galls are often invaded by other parasites or eaten by raccoons and opossums, who dearly love the sweet treats inside. Yokuts Indians harvested old Oak Apple Galls and used them for tinder. We have no explanation as to why this tree has so many, while the neighboring trees have few. Kaweah Oaks Preserve, although basically natural, has needed some habitat restoration and exotic weed eradication.
Management is a never-ending task taken on by a few dedicated volunteers.
We need more help in keeping the trails open and comfortable to hike. Please call our office at 738-0211 and volunteer to assist in managing Kaweah Oaks Preserve for everybody's benefit. We hope you have enjoyed your hike and that this information has provided a better understanding of the Kaweah Oaks Preserve's Riparian Forest and Valley Oak Woodland landscapes and their inhabitants. Thank you for helping keep Kaweah Oaks Preserve natural by leaving it as you found it and not disturbing the native wildlife. Come again each season of the year and observe the many changes in the plants, birds and animals.
