{tab=Trip Recap}

Almost twently CNPS members and friends invested a portion of their Memorial Day weekend to enjoy the outdoors and see some of the plants and wildlife at Casper's Wilderness Park, off Hwy 74, east of San Juan Capistrano. Laura Camp, who knows the park well, led the group and offered excellent narration as we travelled. Some might remember Laura's excellent program about the park that she gave at our chapter meeting a couple of months ago.

After assembling at the far end of the park road on a cool, cloudy morning, we headed off up Dick Loskorn Trail. We climbing slowly above the valley and onto the western ridge of the park, as the weather began to warm and jackets began to come off. We then travelled north along West Ridge trail. This ridge trail had recently undergone maintenance and some of the trail edge plants were destroyed, but we still found plenty. After a bit less than a mile the group descended down Starr Rise Trail and then back to the starting point via beautiful Oak Trail.

The plants, like the habitats, were diverse and Laura discussed many while the attendees took notes and photos, learning as they went. Some of the highlights of the morning included Dudleya edulis and D. multicaulis - many-stemmed dudleya, three species of Calochortus, Clarkia epiloboides – willow-herb clarkia, both Croton californicus and Croton setiger, Eriastrum sapphirinum – sapphire woolly-star, four species of Pseudognaphalium - everlasting and Rafinesquia californica – California chicory,  For a complete list of all 121 species identified during the trip see the next tab "Plants Seen".
