New Poster - FWS Repositories at Your Service

Did you know that we have three repositories? At NCTC, we house the USFWS Museum/Archives. D.C. Booth Historic National Fish Hatchery and Archives houses the Fish and Aquatic Conservation Archives. And, the National Wildlife Property Repository receives forfeited or abandoned wildlife property from FWS Special Agents and Wildlife Inspectors, and more

Before you toss out anything that might qualify as a historic object, photo, or document, contact the relevant repository for assistance. To order this new poster, designed by the Heritage Committee's Artifacts Subcommittee, please contact

Guidelines for Identifying and Preserving Historical Objects

Preservation Mouse PadPreservation Mouse Pad

The U.S. Fish and Wildlife Service needs you to help save our historic documents and objects before they are lost forever

What would you do if you discovered an old object on your station that looked important (e.g., a duck stamp signed by "Ding Darling or magnifying glass used by Rachel Carson)? Where do you preserve the key documents and objects that mark the opening of a new station or a station that was founded over 100 years ago?  These materials are an integral part of a station’s history, and, therefore, the heritage of the Service. So are some of the unique and antiquated equipment used by the station. Saving important documents and objects housed in refuge or hatchery offices, regional offices, or other Service facilities is an important responsibility that all Service personnel should consider part of their everyday job (see Heritage Activity Goals).  In addition to holding historical objects in trust for the American public, preservation of the Service’s heritage can provide material for education about the Service’s mission and accomplishments in conserving the nation’s fish, wildlife and plant resources. It is paramount that our generation ensure that the remnants and reflections of our proud heritage are not lost to generations to come.

The Department of the Interior (DOI) is second only to the Smithsonian Institution in holding natural and cultural objects in trust for the American public. With over 117 million objects and documents, Interior’s collections run the gamut from art to zoology. As part of DOI, the U.S. Fish and Wildlife Service (Service) has its own unique heritage and a prominent place in the Country’s conservation history to contribute to this collection. The purpose of these guidelines is to provide Service personnel with basic information on what and how to preserve significant Service documents and objects. This information is only intended to be used as a quick reference for questions about preservation in the Service. For more specific assistance, you can reference the documents cited below, visit the website (, or contact your Regional Museum Property Coordinator listed below.

Deciding What to Save

The first thing to remember in preservation is that ‘If it is treated as junk, it becomes junk’.   Therefore, knowing what has historical significance and what does not is important.  There are no real hard and fast rules of identifying what is important. There are no real hard and fast rules, but here are some general guidelines that can point you in the right direction.

If a document or object is associated with, or signed by a significant figure, it should be saved.  A significant figure could be the President, Service Director, prominent conservation figure (such as Rachel Carson or Jay N. "Ding" Darling), or other person important to a station, cause, program.  Special attention should be given to documents that include hand-written notes or annotations by a significant figure.

If a document or object is associated with a significant event, program, occurrence, or activity (e.g., the station’s founding, the condor recovery program, etc.), it should be saved.

If a document or object is rare, extremely old, or valuable, it should be saved.

If an object or document represents a common activity that was used in the mission of the station or the Service, representative samples should be saved for posterity.  For instance, the cannon net from Swan Lake NWR, fish hatching jars, and banding pliers represent what we do, and how we accomplished our day to day activities.  Objects like these should be represented in our Service museums. 

If a document or photograph captures the history of the land prior to the development of a refuge or hatchery, it is important and should be saved.

Lastly, your instinct can help identify other items not covered by the previous examples.  If you have a feeling that something is historic and of importance to the heritage of the Service, the document or object should be kept.  Don’t be afraid to trust your instincts!  

Museum Property

The following categories of items already exist as USFWS museum property and provide further examples and definitions of the types of object to consider preserving for their historical value.

Archaeological Collections: Archaeological artifacts usually resulting from systematic research on Service lands. Artifacts and records of the project must be curated by law and regulation.

Ethnographic Materials: Items associated with traditional culture and life ways of indigenous or ethnic groups, such as clothing, blankets, baskets.

Art: Paintings, drawings, prints, wildlife mounts, antiques, sculptures, and tapestries. 

Documents Which are not Official Records as defined by the National Archives: Commissioned photographs, documents associated with an important event or person in Service history, audio and visual images. 

Historical Objects Related to FWS: Early equipment or tools, historic fire arms, decoys, furniture, scale models, and boundary signs. 

Botanical Collections: Herbariums

Geological Collections: Soil Samples, core samples and geophysical specimens to document land forms or in support of engineering studies. 

Zoological Collections: Prepared biological specimens, wet specimens, type specimens, voucher specimens, wildlife mounts with scientific, historic, or long term educational value. 

Paleontological Collections: Vertebrate and invertebrate fossils found on Service lands. 

Environmental Samples: Samples of water, soil, air; collected to document base line conditions for long term research, monitoring, and other analysis. 

The following items are examples of objects that are not usually considered significant for preservation by the Service:

  • Official records as defined by the National Archives
  • Most books (See 126 FW 1)
  • Mass-produced posters or reprints
  • Working collections and samples consumed in analysis
  • Expendable teaching collections
  • Mounted zoological specimens having no scientific, historic, or long term interpretive value.
  • Exhibit cases, dioramas, special lighting, and graphics used for display
  • Seized Law Enforcement property

Tips for Preserving Historic Objects

Once you have determined an object or document is likely to be historically significant, the next step is to ensure that it will be preserved into the distant future.  Accomplishing this can be simple - none of these actions are time consuming nor difficult to accomplish.  The first step is to document the object. Accountability affords the object some level of security!  Next, use the following rules of thumb to assist you in preserving materials at your station.

The most important step in ensuring the long-term preservation of any object is to place it in a stable, controlled environment.  Doing this will protect it from adverse conditions that would promote or accelerate deterioration.  Perhaps the most important environmental factor to control is the relative humidity (RH).  We should think of objects as sponges. They absorb and release moisture from the air around them, which causes shrinkage and swelling.  To avoid the constant movement from swelling and shrinking, the relative humidity in the atmosphere should be kept as stable as possible; with optimal levels at about 40% to 55% RH.  Temperature should not fluctuate either, as it affects RH (the higher the temperature, the more moisture the air can hold).  Temperature should be kept as close to 65 to 70 degrees Fahrenheit as possible.

The object, especially if it is a document or photograph, should be put into some sort of polyethylene sleeve or protective cabinet, archival box or polyethylene bag.  This will help inhibit rapid fluctuation in RH and temperature, and keep out airborne soils, pollutants, and pests.  It should be kept out of sunlight, and away from all light if possible.  Light is very destructive, and damage is cumulative.  In other words, a little light for a long period of time is as bad as a lot of light for a shorter period of time.  Direct light also causes a rise in temperature.  It has been proven that for every 18 degrees Fahrenheit increase in temperature, the molecular deterioration of an objects doubles.

Hot attics and damp basements are probably the worst places to store objects.  Think of your museum object as a person. It wants to be in a cool dry place at all times; free of pests, molds, and airborne pollutants.  More detailed tips on taking care of objects by specific material types can be found in CCI Notes and NPS Conserve-o-grams at the websites listed below.  These are available at the world wide web addresses and from contact people listed below.  If you want the item preserved off-site, contact your Regional Museum Property Coordinator or the NCTC Museum Curator for assistance.

If you decide to preserve the item off-site, you can request your item, as well as other items, to use for education and outreach purposes (i.e. public education programs, special functions at your refuge or hatchery, exhibitions, or other special occasions). Items that are maintained by NCTC can be borrowed for many different purposes to help you promote the mission of the Service at your local station or office. You should contact the NCTC Museum Curator for assistance in these matters.
