Up at 5:30 this morning and out the door by 6:00 am to go with my friend and fellow naturalist Roxanne to the Effie Yeaw Nature Center. I’m starting my Trail Walker duties there again after several months off. I still need a neon orange reflective vest to wear (it was due today) to look more “official”, and I’ll wear that next time. I can also wear the khaki vest my naturalist students bought for me, but it’s heavier material and I think it’ll be too warm to wear in the summer months. So, today, I was just in shirt-sleeves – no vest.
It was about 61° when we got there, and warmed up quickly. The high today was around 100°.
Rox and I were most focused on finding galls, and checked out some of the Valley oaks, Blue oaks and Live Oak trees scattered around the preserve. It’s still a little bit early in the season, but we saw quite a few different species. On the Blue oaks, we found some small specimens of Crystalline galls, Plate galls, Saucer galls, and Urchin galls. On the Valley Oaks we found Red Cones, Fimbriate galls, a Yellow Wig, and Spiny Turbans.
And I was really happy to find lots of the spiny first-generation galls of the wasp Callirhytis quercuspomiformis. I hadn’t seen them there yet (since the trees were trimmed), and was so happy that they had re-established themselves. When they’re new and bright green, they feel spongy, but as the galls age, they firm up and turn tannish-brown.
We saw a few deer, including a pair of bucks in their velvet: a four-pointer and a three-pointer. (The eye guards don’t count.) When their antlers are growing, they’re very sensitive to touch, so there was no head-butting… just a deep long stare from the older buck telling the younger one to back off.
We also saw a couple of females, one near the nature center and one out by the river. They were by themselves and we speculated that they were either young does that didn’t have fawns this year. July is the fawning season at the preserve, but we didn’t see any babies during this trip.

When we were heading out of the preserve after about 3 hours, we came across Rachael,the volunteer coordinator, who was helping to woman the docent table outside of the nature center building with some of the other volunteers. She told us that earlier that morning, some of the docents had seen “tiny baby” coyote pups along the River Trail at the preserve! Oooooo, how cool! I’d love to be able to see those little guys. I’ll have to keep an eye out for them the next time I’m out there.
She also said that later this summer, the river front near the preserve will be re-groomed to provide more spawning space for salmon. Last year similar work was done along the Sailor Bar portion of the river, and this year will be the Effie Yeaw area’s turn. The refit and reconstruction of salmon-friendly habitat will include dredging and reforming some of the river bed, and laying down tons of gravel that’s of the right size and consistency for the salmons’ “redds” (nests). If the gravel is too big or too little, the salmon won’t lay their eggs on it. The work at Sailor Bar was first done in 2009 and during that year about 1000 redds were spotted in the area. Last year, there were ZERO because the majority of the finer gravel had washed away.
It’ll be interesting to watch the work progress in the river near the Effie Yeaw Nature Center/Preserve, and fun to see if lots of salmon can be spotted from the shore in the fall and winter months.
