Angelo State Natural History Collections

The Biology Department maintains the Angelo State Natural History Collections, which contains nearly 150,000 specimens of all types of living organisms. The collections are preserved, documented and curated assemblages that are important to a wide array of human activities.

The collections are essential to the management of natural resources because they document the diversity and biology of organisms that impact agriculture, health and urban and other rural activities. They also characterize the ecosystems that we all depend on.

The collections are a resource for many fields of biological research. The presence and growth of the collections at ASU are important to the university, San Angelo and the Concho Valley because they are a readily available local resource for the region.


The collections have been very active for the last two years, thanks in part to a grant awarded to the ASNHC by the National Science Foundation’s Collections in Support of Biological Research program.  The 3-year grant, “Modernization and Digitization of the Angelo State Natural History Collections” (NSF Grant Number 1203363) is for $480,865 and is providing the means to make some real changes to the ASNHC.  Once the project is completed, the specimens will be accessible to the research and education communities on a global scale for the first time. 


Use of the Collections

All qualified visitors can study the specimens by making an appointment or by taking out a loan. Contact at for loan requests or the appropriate curator. To learn more about each collection, use the links provided.

A researcher wanting to borrow any materials must make a loan request in writing to the appropriate curator. Loans are made for a period of six months with extensions possible by written request. Destructive sampling requests will be considered by the curators.

Please refer to the ASNHC Tissue Loan Policy regarding the information that should be included in a request.

Searchable Databases

Data for the collections is managed through Specify 6.  Selected information can be searched through our web portal managed by SilverBiology. 

Through the NSF grant, every effort is being made to ensure the accuracy of cataloged information.  However, as the collection data are actively being cleaned and updated, researchers and other users are strongly encouraged to verify information before use or publication.   This can be done by contacting the Collections Manager.
