Irish Hills Trailhead
Address: 1691 Madonna Rd, San Luis Obispo, CA 93405, USA

Sunday, April 16th, 1:00 p.m

Join us for a plant walk from the Madonna Road trailhead (southwestern terminus of Madonna Rd.) into the upper reaches of the Irish Hills Open Space.

The vast majority of soils in this area are derived from serpentine, which is a metamorphic rock, high in magnesium and iron, while low in calcium, phosphorus, and potassium. The excess magnesium in combination with low levels of calcium, phosphorus, and potassium create a stressful environment for plant growth, and therefore inhibit the growth of the vast majority of both native and introduced species. The unique assortment of plants that do grow in the Irish Hills and on other serpentine-based outcrops surrounding San Luis Obispo, make for an exceptional mixture, which we will see in bloom on this walk. A plant list will be provided.

The length is 5 miles, 700 ft. elevation gain, 3 hours. Be sure to bring water, food, sturdy shoes, sunscreen, a hat, and layered clothing, as needed.

    New Reservoir Canyon Trail Plant Walk

    Join us for a plant ID walk in Reservoir Canyon and the new trail that leads to Bowden Ranch. The focus of this fieldtrip will be riparian and serpentine plant communities, plants one would regularly encounter throughout much of the greenbelt surrounding the city of San Luis Obispo. It is 4 miles up and back, ascending 800 ft. The ascent is gradual, along a winding trail towards the top of the ridge. Come and learn the easy to identify species. Pick out plants that attract you. Bring native plant samples with you to be identified.

    Meet at Santa Rosa Park in SLO at 8:45 am (to car pool to the trailhead) or at the Reservoir Canyon trailhead at 9:00 am (parking can be limited). Make sure to bring water and snacks. Sturdy shoes, sunscreen, hats, and layered clothing are recommended. No RSVP needed and no dogs please. Also, bring paper and pencil to take notes, and a camera for a photo record. If you would like a preprinted copy of the plant list for this walk, let the hike leader know 24 hours in advance.
