Curatorial Practices for Botanical Gardens by Timothy C. Hohn Pdf
This breakthrough handbook for botanical garden and arboretum curators (and curators in training) has now been expanded and updated fifteen years after the last edition was published. The new edition includes up-to-date information and methods for the preservation and conservation of plants and their use in both ex-situ and in-situ conservation programs, habitat restorations, and conservation research. There are expanded and updated sections on plant acquisitions and field collecting that conform to the Convention on Biological Diversity protocols. New technologies for documenting plant collections are described including reviews of the most common software programs to streamline this process. Recommendations for plant preservation—caring for collections—have been updated with expanded information on basic horticulture practice, sustainable techniques, special applications for conservation collections, and examples of preservation plans. There is an entirely new section on collections research and applications with several chapters on the latest conservation practices, technologies, and programs involving collections. All of the basic and essential information for collections management contained within the first edition, including specific recommendations and examples, has been expanded and updated with recommendations on new technologies and procedures to assist and guide curators in their critical role as plant collection developers, managers, and programmers. What is an important resource for public garden professionals and students has now become even more essential.
An intimate look at one majestic hundred-year-old oak tree through four seasons--and the reality of global climate change it reveals. In the life of this one grand oak, we can see for ourselves the results of one hundred years of rapid environmental change. It's leafing out earlier, and dropping its leaves later as the climate warms. Even the inner workings of individual leaves have changed to accommodate more CO2 in our atmosphere. Climate science can seem dense, remote, and abstract. But through the lens of this one tree, it becomes immediate and intimate. In Witness Tree, environmental reporter Lynda V. Mapes takes us through her year living with one red oak at the Harvard Forest. We learn about carbon cycles and leaf physiology, but also experience the seasons as people have for centuries, watching for each new bud, and listening for each new bird and frog call in spring. We savor the cadence of falling autumn leaves, and glory of snow and starry winter nights. Lynda takes us along as she climbs high into the oak's swaying boughs, and scientists core deep into the oak's heartwood, dig into its roots and probe the teeming life of the soil. She brings us eye-level with garter snakes and newts, and alongside the squirrels and jays devouring the oak's acorns. Season by season she reveals the secrets of trees, how they work, and sustain a vast community of lives, including our own. The oak is a living timeline and witness to climate change. While stark in its implications, Witness Tree is a beautiful and lyrical read, rich in detail, sweeps of weather, history, people, and animals. It is a story rooted in hope, beauty, wonder, and the possibility of renewal in people's connection to nature.
“A timely and much needed call to plant, protect, and delight in these diverse, life-giving giants.” —David George Haskell, author of The Forest Unseen and The Songs of Trees With Bringing Nature Home, Doug Tallamy changed the conversation about gardening in America. His second book, the New York Times bestseller Nature’s Best Hope, urged homeowners to take conservation into their own hands. Now, he is turning his advocacy to one of the most important species of the plant kingdom—the mighty oak tree. Oaks sustain a complex and fascinating web of wildlife. The Nature of Oaks reveals what is going on in oak trees month by month, highlighting the seasonal cycles of life, death, and renewal. From woodpeckers who collect and store hundreds of acorns for sustenance to the beauty of jewel caterpillars, Tallamy illuminates and celebrates the wonders that occur right in our own backyards. He also shares practical advice about how to plant and care for an oak, along with information about the best oak species for your area. The Nature of Oaks will inspire you to treasure these trees and to act to nurture and protect them.
