Re: Barnes TSX/TTSX vs Nosler Partition
And they further state that the current ban which hunters have been 99.9% compliant has not had a measurable effect yet that if they get rid of all lead ammo the problem will be solved. I don't quite get it.
Following this section they talk about all animals in the food chain being affected by lead, inferring that the next logical move would be a complete ban of hunting with bullets containing lead.
These results are especially pertinent given recent regulatory
efforts in California to mitigate the lead exposure hazard to
California condors by partial bans of lead ammunition use in
condor habitat (39, 40). Although these regulations have been
in place for only a few years, we looked for evidence that they
had impacted the prevalence of lead poisoning in California
condors. We compared blood lead levels in birds in 2006-2007
(preban) with levels in 2009–2010 (postban) and found no in-
dication that blood lead levels had declined in 2009–2010 com-
pared with 2006–2007, suggesting that, at
least thus far, the regulations to help reduce lead exposure in
condors have not been effective.
Here, we describe a situation in which intensive ongoing man-
agement efforts conceal the lack of true recovery of a critically
endangered species. Despite the recovery efforts for the California
condor, this species is not on a trajectory to a self-sustaining
wild population. Our demographic model clearly illustrates
that, without reduced lead poisoning, the California condor
will require extraordinary management efforts in perpetuity
to avoid again declining to extinction in the wild. Additionally,
our analyses show that, if the lead exposure hazard is removed
and thus lead deaths are halted or severely reduced, California
condors could once again achieve a sustainable wild popula-
tion. Although we present work only on condors in California,
the condor populations in Arizona and Baja California are also
experiencing impacts from lead poisonings.
