“In every walk with nature, one receives far more than he seeks.”
— John Muir
Yesterday’s SCVN Friday hike took place on the Sunset Trail,
a popular summertime hike on Mt. Lemmon connecting hikers
to Marshall Gulch without having to drive all the way up through Summerhaven.

Another Fall of Teaching Children About Nature In Sabino Canyon 
We began the tour by meeting at the McDonald’s at Catalina Highway where David provided an overview of the biomes of the Catalinas. Before starting the car caravan up Catalina Highway, David covered the lower biomes, the Saguaro-Palo Verde (100′ – 4,000′), which includes the dominant cacti and legume trees; the Desert Grassland (3,800″ – 5,000′) with grasses, succulents & shrubs being dominant. 
At about the 5.5-mile marker, we pulled off at Molino Basin where David lead a discussion on the Oak – Grassland biome (4,000′ – 5,600′) and Oak Woodland (5,000′ – 6,000′) biome. Here he used posters and the natural taurine to cover; Trees: Emory Oak, Mexican Blue Oak, Silverleaf Oak, Arizona White Oak, Alligator Juniper, Western Soapberry, Border Pinyon Pine: Shrubs: Mountain Yucca, Soap-Tree Yucca, Shindagger Agave, Sotol, Golden-flowered Agave, Beargrass; Grasses: AZ Panic Grass, Blue Grama, Sideoats Grama, Cane beard grass, Spidergrass, Bush Muhly, Bull Grass, Lehmann Lovegrass; Oak – Grassland: Oaks & Junipers, Chihuahua Pine, Buckbrush, Golden-flowered Agave, Mt. Yucca.
Our next stop was along the highway near Bear Creek to discuss the Riparian Corridor (Not a biome) where we found AZ Sycamore, AZ Walnut, Gooding Willow, Fremont Cottonwood, Velvet Ash, AZ Cypress, AZ Alder.
At the approximately the 5,400″ elevation we stopped at the Middle Bear Picnic/Green Mountain Trail Head to learn about Pine-Oak Woodland biome where the dominant plants are AZ Pine, Chihuahua Pine Silverleaf Oak, AZ White Oak, Emory Oak, Black Cherry, Alligator Juniper.
Next, we stopped at Windy Point Vesta(6,500′), a popular place for tourists driving up the scenic Catalina Highway. At this location, David talked about the Chaparral biome, which includes Silver Oak, AZ Madrone, Border Pinyon Pine, Alligator Juniper, Manzanita, Golden-flowered Agave, Beargrass, and Buckbrush.
At the 19.3-mile highway marker (7,825′), David leads a discussion on the Pine Forest biome where the dominant plants are AZ Pine, SW White Pine, Ponderosa Pine and occasional Douglas-Fir.
As you can see, David used live plant specimens on his posters.
Ever wonder how Mt. Lemmon got its name? The highest point in the Santa Catalina Mountains (9,152′) was named after Sara Plummer Lemmon, a respected botanist from New Gloucester, Maine, who arrived in Arizona after living in coastal California. Her Arizona fate was sealed when she attended a botany lecture in 1876 led by her future husband, John Gill Lemmon, and the whirlwind romance was on. After four years of courtship, the two wed and worked together cataloging the flora of the West, which would lead them to the Coronado National Forest in the southern section of what was then the Arizona Territory.
A discussion on the last biome in our tour, Mixed Conifer Forest (Above 8,000′) took place at Bear Wallow (8,100). Here David illustrated the common plants in the Mixed Conifer Forest: Ponderosa Pine, AZ Pine, SW White Pine, Douglas-Fir, White Fir, Quaking Aspen; Silverleaf, Netleaf, and Gambel Oaks; Rocky Mountain, Big Tooth, and Box Elder Maples.
