Monarch Tagging 2019
From mid-August until early October, licensed collectors capture Monarch butterflies as they stop to nectar at Rosetta McClain Gardens. The team tags the butterflies and gathers research data that is submitted to monarchwatch.org, a program run through the University of Kansas. The park sits on the Scarborough bluffs, right on the migration path of the Monarchs. The project has an amazing recovery rate of tags in Mexico, specifically at Cerro Pelon, a Monarch biosphere reserve about the same size as Rosetta. Nearly 1% of Rosetta's tags have been found there. It is amazing that these Monarchs travel 3000km from such a small park in Ontario to yet another small park in Mexico. Monarchs are the only butterfly in the world that travels such a long distance. Come visit and witness the beginning of a remarkable migration!
Directions
