Mission: Fragile Inheritance promotes and supports the long term study of species and habitats, human & environmental effects on them, and the conservation of biodiversity, based on the lifetime work of Fred Schueler & Aleta Karstad.

"Wow this is an awesome database! . . . it looks like the records have everything I am interested in."

Doing the Streets

This study is done around our home in Bishops Mills, Ontario, a small village of about 100 inhabitants, on the Smiths Falls Limestone Plain.

After a preliminary season in the summer and fall of 2003, we have, when home, tallied all on-road animals on the 246 metres of four streets fronting on land that we owned in 2003. Surveys are made when possible, especially when the pavement is wet or animals are moving. Average duration of a survey was about 10 minutes. Air temperature, wind, cloud cover, precipitation, and the estimated percentage of the pavement that is wet are recorded at each survey.

We’re using roads here as a nuclear physicist uses a particle detector, not to directly fret about the roads' impact on animal populations, but to to find seasonal patterns of movement. All alive and dead mammals, birds, and invertebrates are picked up and measured/dissected as appropriate, with regular reporting of Earthworms and slugs added in the spring of 2005.

Data from this project is also being analyzed by other researchers to study life cycles, local extinctions, invasive populations, and the effects of changes in land use and climate.

Doing the streets

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.
