The Ernst Mayr Library and Archives of the Museum of Comparative Zoology (MCZ), Harvard University, holds a unique and extensive collection of photographs, letters, manuscripts and field notes of William Brewster, a prominent ornithologist/naturalist of the late 19th and early 20th centuries. His published work is lauded as providing authoritative and novel additions to ornithology.

Brewster published more than 300 ornithological papers and several books which are widely available in academic and research libraries. He was the first president of the Massachusetts Audubon Society and was a founding member of the Nuttall Ornithological Club, out of which grew the national organization, the American Ornithologists’ Union. Brewster served as President of the American Ornithologists’ Union from 1895 to 1898, and the organization has awarded a medal in Brewster’s name since 1921.

Brewster’s ornithological studies covered the United States, although he worked most extensively in New England. Brewster was a Curator of Ornithology in the Harvard University Museum of Comparative Zoology from 1885 to 1902, continuing to work in the MCZ until his death in 1919. He deposited his bird specimen collection in the MCZ and his associated works such as his journals, diaries, correspondence and some photographic works in the Ernst Mayr Library & MCZ Archives. Brewster’s extensive specimen collection, in combination with his large body of published work, secures his place in ornithological history.

We often think of natural history libraries serving as memorials for lost species, animals like the passenger pigeon and the dodo living on only in books, photos, and illustrations that tell sad cautionary tales of once-abundant populations lost to overhunting or habitat destruction.

However, such records also tell stories of hope, providing valuable resources for modern scientists working to protect threatened wildlife. Since it was founded in 2006, BHL’s historical documents have supported the work of conservationists devoted to saving everything from Caribbean mammals to rare wetland plants. Not only are accessible records that describe the historic ranges, populations, and other characteristics of a species essential for researchers, but they help remind the public of how vibrant historical ecosystems were—and the importance of protecting what is left.

“The real advantage of BHL is keeping our ecological memory intact, and not allowing us to collectively forget how beautiful, wild, and diverse ecosystems of the past were,” wrote historical ecologist Dr. Joshua Drew in a blog post from BHL’s 2020 Earth Optimism campaign. “If we succumb to this collective amnesia, we risk setting our conservation bar too low and allowing the dulling of our natural environments to continue without even recognizing our losses.”

As part of BHL’s Earth Optimism series, we’re sharing the conservation success stories of four bird species, all prominently featured in the BHL collection, whose impending losses were reversed through the efforts of concerned citizens and researchers.

Feathers have been used in fashion throughout history, but the trend became more widespread from the late 18^th century when the Industrial Revolution made luxuries more available to the masses. In the 19^th century, new technology improved the speed of production and the millinery industry boomed. Hats with feathers became a status symbol coveted by a new mass market and were produced on an industrial scale.

Birds were hunted around the world to supply plumes to centres of fashion such as London and New York. In 1886, American Museum of Natural History’s ornithologist, Frank Chapman, infamously observed on a walk in New York some 40 native bird species on women’s hats, some with an entire stuffed bird attached. Indeed, women were oft blamed for the trend: in The Ibis in 1887, women were pointed to as “the indirect, but real, instigators of this slaughter”. The author continues: “all that can be hoped for is that the freaks of feminine vanity may take some other and less harmful direction.”

The solitary sea squirt Ascidiella aspersa is native to the Northeastern Atlantic, from the Mediterranean Sea to Norway. Living in shallow sheltered sites and harbors, this species has a fast growth rate and is able to produce a large number of larvae.

These attributes have helped make it a successful colonizer of non-native environments, such as the Southwestern Atlantic, where it has become an invasive species introduced likely via ships.

Dr. Evangelina Schwindt, Head of the Grupo de Ecología en Ambientes Costeros from CONICET in Argentina, studies Ascidiella aspersa as part of her research as a marine invasive ecologist. Her work involves researching the interactions between invasive and native species, the patterns and processes occurring in biological invasions from the historical and present-day perspectives, the impact caused by invasive species, and the management strategies that can be applied.

Alexander von Humboldt (1769-1859) was a man who believed all of nature was interconnected, and that by affecting one aspect of nature, other parts of nature would be affected, too—for good or ill. Humboldt believed that one’s own emotions and subjective views were necessary in order to completely experience nature. Simply taking measurements or classifying animals, plants, rocks and other forms of life would never allow one to fully experience the truth of nature.

Little Lake Valley, located in northern California’s Eel River watershed, is home to several thousand acres of wet meadows and riparian woodlands that are habitat for diverse plants and wildlife, including tule elk, many bird species, and gorgeous spring wildflower displays. A landscape formed when sediments from several creeks filled an intermountain valley bounded by faults, the Valley is also home to two rare plants: the North Coast semaphore grass (state-listed as Threatened) and Baker’s meadowfoam (state-listed as Rare).

“The large lowland wetland ecosystem found in the Little Lake Valley, if not unique, is quite rare,” asserts Dr. Robert E. Preston, a Senior Biologist in the Sacramento office of ICF, an international consulting firm. “Most or all of the small interior valleys of California’s North Coast Ranges were long ago converted to agriculture or were hydrologically altered. Moreover, it supports almost half of the known occurrences of Baker’s meadowfoam, including the largest and most extensive population.”

In November 2016, the California Department of Transportation (Caltrans) completed construction of the Willits Bypass Project, a 5.9-mile long bypass of US Highway 101 in Mendocino County. First proposed in 1957, the controversial project, which crosses a corner of Little Lake Valley, raised a variety of environmental concerns due to its impact on endangered species and state and federally regulated resources [1].

Preston served as the lead botanist for the team that prepared the Project’s Mitigation and Monitoring Plan, which was developed and is being implemented by Caltrans to offset the bypass’ impacts on wetlands and rare plants.

George Perkins Marsh was a talented linguist, scholar, and diplomat. He served as a member of the U.S. House of Representatives from Vermont’s 3rd district from 1843-1849, and, in 1850, went on to become United States Minister to the Ottoman Empire. In 1861 he was appointed by President Lincoln as the first Ambassador to the Kingdom of Italy, where he served until his death at Vallombrosa in 1882. A Vermonter raised close to the forests of the Adirondack Mountains, Marsh is remembered today chiefly for his role as an early and influential pioneer of the conservation movement in the United States. His book Man and Nature:Or, Physical Geography as Modified by Human Action, published in 1864, is recognized for his early recognition of the interdependency of the natural world, the effects that human actions can have upon it, and the responsibilities that humans bear for those actions.
