context_page_description: The conservation and restoration of herbaria includes the preventive care, repair, and restoration of herbarium specimens. Collections of dried plant specimens are collected from their native habitats, identified by experts, pressed, and mounted onto archival paper. Care is taken to make sure major morphological characteristics are visible. Herbaria documentation provides a record of botanical diversity. This is becoming increasingly important as habitats continue to be destroyed and climate change alters growth ranges and patterns of plant life.
  Professionals who make decisions about the conservation-restoration of botanical specimens include registrars, curators, and conservators who work on herbarium collections in universities and museums. Herbarium specimens may be susceptible to water damage, mold, pests, unattached specimens, dust, dirt, and damage from improper storage conditions. Preventive conservation can prevent much of the damage that could occur.
context_section_description: A herbarium is a collection of preserved plant specimens and associated data used for scientific study. Originally, the word "herbarium" referred to books about medicinal plants. In 1700, French botanist Joseph Pitton de Tournefort used the word to describe a collection of dried plants and Carl Linnaeus continued to use this term in his work which is where the term caught on. Initially, herbarium collections were bound in volumes instead of on individual sheets as it is done today. It is not exactly known how long dry plant specimens last in storage, but with proper conservation, they have been able to last many years. Specimens collected by Linnaeus in the eighteenth century and by Banks and Solander on the Endeavour voyage in 1788 are still excellently preserved. The specimens may be whole plants or plant parts. These will usually be dried and pressed and mounted on a sheet of paper but, depending upon the material, may also be stored in boxes or kept in alcohol or other preservatives.
