Mission Trails Guides Journey to Santa Margarita Reserve in Fallbrook
As a trail guide and naturalist, I was invited to hike the Santa Margarita Ecological Reserve in Fallbrook, CA where a group of us, led by one of the Reserve´s docents, explored the rich riparian ecosystem of native plants and wildlife. The Santa Margarita Ecological Reserve is dedicated to keeping the land it in its natural state for educational and research purposes.
Santa Margarita Creek and Oak Woodlands
Anxious to “get back to nature” our group started out along a path through the coast live oak woodlands where the docent spoke about the native oaks and the importance of preserving the land along the Santa Margarita River, one of the last “free-flowing” rivers in the coastal Southern California region. Walking through the dappled sunshine, crunching fallen leaves, I felt like I was in the middle of a wilderness and could imagine the Native Americans, the Luisenos, trampling the same path in their agave sandals.
I spotted a small seedling in the middle of the trail with an acorn from the coast live oak still attached and thought to myself, “so that´s how acorns grow into big oak trees.” I was too embarrassed to share my thoughts with my fellow trail guides because, of course, oak trees do come from acorns. It´s just that I had never seen an acorn take root before and I was so in awe of this little life growing out of the ground.
Further along the trail, I looked up into the branches of an oak and found what is called an oak gall, or oak apple. These “apples” are not for eating since they contain frass (insect pooh). Some galls are beautiful and different in color; the coast live oak gall tends to be a light reddish-brown or beige. From my trail guide training at Mission Trails, I remembered that the oak gall is created by the larvae of a cynipid wasp. The wasp lays its eggs in the bark or on a leaf, once the eggs are hatched, the larvae then begin to chew and the saliva triggers a chemical reaction in the oak tree, causing tissue to form into small balls. These ancient coast live oaks host over 200 species of gall wasps, more than any other tree in the western states.
The White Lined Sphinx Moth and European Cabbage White Butterfly
Up ahead, several hikers were gathered around Bill Howell, MTRP Trail Guide Instructor and Naturalist, to look at the caterpillar he had in his hand. It was green and yellow with a horn; a White-lined sphinx caterpillar. This little guy likes to eat the flowers from the native evening primrose but in domestic gardens, it will settle for the flowers of a fuchsia. The sole purpose of the sphinx caterpillar is to eat and get fat before transcending into its moth state.
Tree Hugger Pest Control
As a trail guide and naturalist, I am often asked “What is a tree-hugger like you doing working for a pest control company?” Good question. Although I embrace nature and get excited over seeing an acorn take root or a colorful caterpillar, I also understand the need for pest management – and that under the watchful eye of Hearts Pest Management, pest control becomes very compatible with the views of us “tree hugger” naturalists. According to the California Department of Food and Agriculture, there are devastating results from invasive species of pests (non-native) on California crops with an estimated loss of $3 billion annually.Santa Margarita Ecological Reserve, Fallbrook, CA – Bibliography
