After visiting at least ten different Civil War battlefields in Mississippi, Tennessee and Georgia last summer ( which you can read about here ), Eric and I headed even farther east to spend a few days in beautiful Great Smoky Mountains National Park.  I visited this park 15 years ago, and I was eager to see it again - especially one of my favorite places, Cade's Cove.  A hotspot of biodiversity in the Southeastern United States, Great Smoky Mountains National Park is a naturalist's delight.  We did some birding during our visit to the park, but most of our time was spent hiking through lush forests and rambling around the many old cabins and homesteads that have been carefully preserved by the National Park Service.  A handsome American Black Bear: easy to see why these guys are everyone's favorite North American mammal! The most noteworthy mammals we encountered on our visit were, without contest, all the bears! American Black Bears are abundant in Great Smoky Moun...

If you've been with me through Parts I  and II of this series, where we talked about the arguments against damming and flooding Del Puerto Canyon and then looked at a long list of sensitive species that may be displaced by the project, you may have a few questions. You may be thinking,  with thousands of acres of habitat available in the Coast Ranges, why would the loss of a mere thousand acres matter?  Isn't there plenty of available habitat left for wildlife?  What is the point of this, anyway? Progress is progress,  you say,  water is life, agriculture feeds the Valley (and many, many far-flung regions beyond), so what is the loss of a thousand or so acres of habitat in the grand scheme of things? Yet this has been the story over and over and over again in California, for the last 200 years: the relentless march of "progress," taking all we can possibly take with little regard for the destruction left behind.   Habitat fragmentation has plague...

In Part I , we looked at a few of the reasons the proposed dam at the mouth of Del Puerto Canyon has caused such a great deal of opposition within the local community.  Some of the arguments against the dam include the risk of flooding that a dam failure would present to the city of Patterson, the loss of educational and recreational access to the lower canyon, destruction of Native American cultural sites, and loss of access to sites of geological and paleontological significance. While there are many valid reasons why this canyon should not be flooded, perhaps the most significant to me, as a naturalist, is the loss of wildlife habitat and disruption of wildlife corridors that would follow.   Below are excerpts from the environmental impact report (read the full text  here  and  here ) regarding the specific species of wildlife that have the potential to be displaced by the damming and flooding of Del Puerto Canyon. Regarding terrestrial biological resour...

At the western edge of the Great Central Valley, within Stanislaus County, lies a canyon of cultural, biological and geological significance.  A rift in the earth slicing through the Coast Ranges, the canyon exposes millions of years of geologic history, and shows evidence of being occupied by humans long before European settlers arrived on the scene.  A spring at the heart of the canyon feeds into an intermittent stream, bordered by oasis-like pockets of riparian wetlands, cottonwoods, sycamores and ephemeral pools.  In the spring, grasslands within the canyon are verdant with a luxurious covering of new growth and dotted with annual wildflowers, while steep canyon walls are adorned with hardy chaparral and oak scrub habitat.  In the autumn, western sycamores and Fremont cottonwoods lining the creek put on a color show no less spectacular for its subtleness.   This is, of course, Del Puerto Canyon. And this canyon is in imminent danger of being dammed and ...

There are a lot of reasons to love California, particularly as a naturalist. The world's six major biomes, represented in California: Top row: Forest (Redwood State Park); Freshwater (Sword Lake); Desert (Joshua Tree National Park) Bottom row: Marine (Monterey Bay); Grassland (Stanislaus County prairie); Alpine tundra (Yosemite high country) California is a land of extremes, from submarine canyons to alpine peaks, from high heat and aridity to remarkable snow pack.  It boasts the tallest trees, the most massive trees, and the oldest [non-clonal] trees.  Within its borders, one can stand on the tallest point in the conterminous United States (Mount Whitney, 14,500 feet above sea level) as well as the lowest (Badwater Basin, 282 feet below sea level). In addition to the greatest difference in elevation, California also has the greatest range of latitude, the highest soil diversity, the largest range of average annual rainfall and the greatest range of average annua...

Ah, the swamp.  A stinky, mucky, oozy, icky, bug-infested no-man's land, brimming with creepy crawlies and things you'd never want to run into at night.  A place no one wants to visit; a land without use or purpose.  Right? Wrong. Entirely wrong. (Except for the part about being bug-infested.  That part might be true.*) Eric and I recently returned home from visiting friends, family and a slew of historic sites in the Carolinas and Virginia.  We hiked in gloriously verdant forests, birded in exceedingly productive wetlands, swam in the balmy Atlantic, and toured a plethora of places brimming with history: two plantations, five Revolutionary War battlefields, four Civil War battlefields, two forts, and two historic Colonial settlements.  (Aside: I cannot recommend a visit to Colonial Williamsburg and Historic Jamestowne highly enough!!) Perhaps most significantly (for me), we experienced South Carolina's swamps. Swamps, like all other wetlands...
