U.S. Reptile Stats (2009) 4.7 million households owned 13.6 million pet reptiles (1/20 houses had ~3 reptiles) vs. 37,397 hunters/anglers (1/2.5m) $1.4 billion annual revenues for U.S. reptile industry. 11.3 million live reptiles were exported from the United States. 900,000 live reptiles were imported into the United States. U.S. businesses dominate the global reptile industry. Wildlife smuggling (2nd only to drugs) accounts for $8 - $10 billion in sales. Reptiles are arguably the most trafficked live animals.

Removal surveys found chuckwalla populations are slow to recover (small clutches, long lived, little/no migration, habitat specialists). These factors contribute to a population crash post removal.

Reptiles play an important role in the economy, culture, & ecosystems in which they reside Reptiles are niche specialists & “best” indicators for assessing habitat & climate changes (ectothermic or “cold blooded”)

Collection targets & depletes population sources of long lived & reproductively limited species; requiring increased species diversity & collection areas (CA-AZ?) to match market demands Collection is additive to the ongoing list of current threats (e.g., habitat conversion/loss, drought, disease) Data has limited management/scientific value as the market not management dictates collection patterns & trends Given the increasing trend of captive breeding (90% US exports) there is a decreasing need for commercial collection Many of the top collected species fair poorly (die) in captivity (ethics)

Also of Concern: Disease & The Herp Trade
“Amphibians & reptiles are among the most commonly traded animals & this trade has raised concern because of its potential impact on natural populations, animal welfare & the spread of invasive species & emerging infectious disease.”
