The Researching Amphibian Numbers in Alberta (RANA) project was initiated in 1996 and has two objectives:
- to collect detailed information on amphibian populations in Alberta
- to promote public knowledge of amphibians by allowing a hands-on experience
RANA sites have operated at seven different locations around the province.
Active Sites – sites where amphibian studies are currently being conducted:
Inactive Sites – sites where amphibian studies were formerly conducted:
- Beaverhill Bird Observatory
- Cypress Hills Provincial Park
- Lesser Slave Lake Provincial Park
- Saskatoon Island Provincial Park
How amphibian monitoring works
- Representative ponds are fenced (plastic or silt fencing) and pitfall traps (aluminum cans sunk into ground) are placed every 10 metres inside and outside along this fencing.
- The fencing directs the amphibians to the traps where they fall into the bottom of the trap.
- Traps are checked daily and animals that are caught are:
- Over the long term, these sites can provide valuable information on populations and productivity. This can help us better understand changes in populations of Alberta amphibians.
