Texas Horned Lizard Watch 10-Year Summary Report

Results – Participation

The number of volunteers formally participating in the watch program has varied since its inception, with a peak of 71 in 1999 (fig. 1) and a general decrease in participation since then. Publicity for the watch was highest in its initial years – probably producing the increased participation in those years. The vast majority of volunteers participate for only one year (fig. 2). Success in seeing a horned lizard does not seem to influence whether or not volunteers continue to participate.
