Turning over a new leaf...


When you change your focus from limitations to boundless possibilities, from doubt and fear, to love and confidence, you open your world in entirely new ways. However, change is not something that necessarily comes easy….Albert Einstein once wrote, “The measure of intelligence is the ability to change.” To truly change…change one’s ideas, habits, perspective, etc. means that one has to have the courage to leap into the unknown. The unknown can be scary, the unknown can often pose an effort of resistance to change. However, it is this resistance that is the only painful aspect of the change at place.

Things are changing rapidly, all the time, for all of us. A new job, a new life, maybe a vacation, perhaps back to school. A shift in gears and a turning of leaves (literally). Fall is on its way, and although today is 80 degrees and bluebird skies in Denver, the crisp mornings and evenings lend homage to the onset of Autumn.

My experience here at the state office for the Colorado BLM has been one for the books. A big step in my overall career building experience, as I have had the opportunity to spend weeks in the field conducting rare plant surveys, and also working behind the scenes with the data, writing technical reports, and even establishing a new demographic monitoring protocol. To be able to use my skills in and out of the field here has been one of the things I have been the most thankful for in this job, as a lot of my past experiences with field work have led me to submerge myself in only a few aspects of the scientific method, whereas here I have been given the opportunity to do much more.

My time here in Colorado has also truly solidified my interest and ambition to continue to pursue education, and with the way things are looking that very well might be possible in the coming months. I have been speaking with a potential adviser about a scholarship opportunity that seems very promising, working on a project well-aligned with my interests in conservation biology, and forest pathology, in a place that would be very, very far away, but would be a great lesson in jumping into the unknown. We will see how things shake out here in the next few months…

While I will not miss the Denver metro area, or the hot muggy summer days…I will miss a lot of things about my time here. My garden, my house, my awesome crew and co-worker Lauren, the nooks and crannies of the Colorado Rockies, full strength beer.

Up next, I am headed to Moab to start a new job with the USGS. The desert has always been a place that has excited pieces of my soul in strange ways, though I have never thought I would be capable of living in the conditions. A summer in Colorado has been rough for me, as I am acclimatized to temperate, cool, rain and fog. From what I hear, the fall in Moab is great though, and I sure am excited to get some red dust all over my bike again.

Cheers to a great season of growth, pursuit, and experience! The adventure continues…

All the best,

From Sea to Snow to Sand

“A man on foot, on horseback or on a bicycle will see more, feel more, enjoy more in one mile than the motorized tourists can in a hundred miles.”

“The extreme clarity of the desert light is equaled by the extreme individuation of desert life forms. Love flowers best in openness and freedom.”

― Edward Abbey, Desert Solitaire

My drive out to Colorado began on the foggy North Coast of California. I packed up my car, took a few final moments in the company of the Ocean, cracked open Desert Solitare and headed east.

Having been to the deserts of Southern California only once, the opportunity to spend some time in the deserts of Nevada, Utah, and western Colorado seemed like the perfect opportunity to kill a bit of time on the drive out. I've always been fascinated by the desert- the dramatic contrast of the landscape, the strategic adaptations, and resilience of the life forms that exist among it, the hidden gems that exist within it. The sense of calm one can reach in the absence of noise at night, under a spectacular portrait of the nights' sky.

A few bike rides, and slot canyons later I arrived in Denver, only to find that I would be heading back to the high deserts of Colorado in my first few weeks of my internship with the Chicago Botanic Garden. For the next few months, I will be working out of the Colorado BLM State office under State botanist Carol Dawson doing rare plant demography and monitoring throughout the State.

A bit about the work:

The threatened and endangered species monitoring program out of the Colorado State office began in 2004 with nine plant species Federally listed under the Endangered Species act, and four candidate species that primarily occur on BLM land. The monitoring program is unique in that for each species, the State Office has employed a demographic monitoring approach to develop a greater understanding of the landscape, and population-level dynamics of each species.

The monitoring of such species is important towards determining the status of imperiled species, at the population and range-wide level, and their potential future condition given different management actions, and environmental stochasticites. Additionally, this monitoring program is important in developing adequate and efficient recovery measures using the best available scientific information possible.

Week 1: Astragalus debequaeus

Astragalus is member of the bean family (Fabaceae). It is considered to be imperiled at the global and state level. A. debequaeus is known only from the Colorado River Valley in Delta, Garfield and Mesa Colorado.

Astragalus is the largest genus of plants in the world, with over 3,000 described species. Rarity and Endemism are common in Astragalus given that the species has a tendency to speciate by the means of edaphic specialization (colonizing a specific soil substrate often confined to a narrow geographic range).

Astragalus debequaeus is a prime example of edaphic specificity, known only from the Atwell Gulch member of the Wasatch formation. A. debequaeus also seems to really enjoy colonizing the steepest, rockiest slopes, making for fun and mildly dangerous sampling sites.

Overall, it was a good first week, with two new macroplot sites scouted, and sampled, and a few tumbles taken.

Week Two: Sclerocactus glaucus

Week two began with a trip back out to Western, Colorado to sample the Colorado Hookless Cactus: Sclerocactus glaucus. S. glaucus populations occur primarily on alluvial benches along the Colorado and Gunnison rivers and their various tributaries. Since 2007, Denver Botanic Gardens and BLM have established over ten monitoring plots to gain a deeper biological understanding of S. glaucus.

A grand majority of known occurrences of S. glaucus occur on BLM managed lands, while a number of other occurrences occur on private lands. Potential threats to this species include: oil and gas development, grazing, and ORV use. Other potential threats include: Climate change (specifically drought-induced effects), predation, and parasitism by the cactus-boarer beetle (Moneilema semipunctuatum).

Unlike A. debequaeus, from the S. glaucus sites we visited, I noticed a much different composition of habitat-types at each site location. One interesting thing we found at one of the sites we sampled was an interesting composition of crypto-biotic soil crusts (a living layer of lichen, moss, microfungi and cyanobacteria that colonize the top layer of soil in many desert landscapes).

Overall, it was a good second week with a few sites showing promise of new recruitment, and a few showing signs of potential decline. For the rest of the week, I will tend to the tasks of data entry, and the further examination of soil crust samples from Sclerocactus sites. For the weekend, I look forward to finishing up some things in my garden, mushroom hunting, and getting some more dirt on my bike.

Until next time,

Sam
