Protect, Transform, Inspire:  This year, celebrating its 50th year, TNC Arizona looks backward at past accomplishments and forward to the future.  The state chapter is committed to affirming core values and aligning goals with its mission.  In Arizona, protecting water resources is of particular urgency.  Hart Prairie with its riparian willows, high altitude wet meadows, and mixed conifer forests, is a locus of significant forest restoration research, in particular its Ponderosa pine forest functioning as a demonstration plot for the larger Four Forest Restoration project (the Forest Service has committed to clearing 30,000 acres per year for the next decade or so).

What is the ecological purpose of a forest?  For one thing, it functions to protect water sources:  northern Arizona forests supply 30% of the water for more than 2 million citizens.  So how do we ensure we have healthy forests?  While this might be considered a “new forestry school” belief, a healthy Ponderosa pine forest is fire-adapted and has about 15-40 trees per acre (as opposed to many areas, where the density is now more like 500 trees per acre, due to fire suppression and lack of management).  When Ponderosa grows thickly, the forest sucks up groundwater and also becomes a candidate for the intense and dangerous crown fires.  With a grant from the US Forest Service, TNC treated 70 acres at the Prairie by thinning the smaller trees; groundwater levels were measured before and after.

The Preserve’s prize Bebb willows (Salix bebbiana) are not a rare species (supposedly, we have them here in New England), but the Hart Prairie community is unique because it is so large.  Most Bebb willows grow in stands of under 50 trees; here there are more than 1300!  This willow species is not particularly attractive (I totally agree that the trees look gnarled and misshapen), but it is an indicator species for a healthy wet meadow.  The willows, which are dioecious, grow from seed, and TNC has tried planting seeds to keep the population either stable or increasing, and has also tried fencing them in to keep them from being munched on by herbivores.

Locale:  The Museum of Northern Arizona was founded in 1928 by Harold and Mary-Russell Ferrell Colton, a wealthy Philadelphia family with a close connection to Dick and Jean Wilson, the benefactors who donated the Hart Prairie Preserve to TNC.  The Museum focuses on the Colorado Plateau: its volcanic geology, its paleontology specimens, and the material remains left by the successive human cultures which inhabited the area.  The collection is also extensive in terms of ethnology, with a focus on the Native American groups who have lived in the area for centuries: the Hopi, Navajo, Zuñi, and some Apache.  Contemporary artisans from these tribes are proud of their traditions, but by incorporating their personal experiences into their work, they enrich their cultures and make them accessible to all; a striking example is the wrap-around mural in the Museum’s Kiva Room.  Being herself an artist and a national leader in arts education, founder Mary Colton clearly understood the value of the arts; thus, the Museum has continued to acquire and exhibit the work of Native American and Anglo-American artists whose work is connected to the Colorado Plateau.  On display this summer are landscape paintings by Curt Walters, beautiful oils of the Grand Canyon and other southwest vistas.  Of course I was mesmerized by the jewelry on display; I am particularly fond of silver and turquoise, and the museum has some outstanding pieces by contemporary Native American artists.

Reflections:  At the Museum, we were allowed to touch a meteorite, which, when you think about it, is one of the strangest things on earth, because it is truly extra-terrestrial!  I was also delighted to hold a dinosaur thigh bone (huge) and mastodon tooth (huge), and I marveled at the relative weights of the volcanic rocks (pumice is as light as air, almost).  The gift shop at the Museum was particularly enticing, and I ended up buying a pair of turquoise earrings (for myself, because this stone is lovely).

I wish I could have had climbing adventures with George, but I am afraid of heights.  I started to feel dizzy even as I was looking at his slides.
