Introduction To The Database

Since 1985 Fred Schueler has been keeping a database that combines catalog and observational information on Canadian natural history. The Fragile Inheritance Database has been structured to handle any kind of observation, including various kinds of text, measurements, and images. This is a general natural history database which can handle any kind of natural history observation, data, or specimen. Our goal is to make this kind of database widely available.

We presently have 152,732 of our records in the database, besides those accumulated from others.

What can we do to increase awareness of habitat loss, invasive species, and human impact on nature?

There is no other independent organized group in Canada which is dedicated to promoting long term monitoring. This is your chance to support the work of Fragile Inheritance.
