A recent commentary in Biological Diversity highlights the Hefei Botanical Garden's innovative and comprehensive efforts in plant germplasm conservation, sustainable resource utilization, and public education, establishing it as a vital benchmark for regional biodiversity protection and urban ecological development in East China.

– California condors are behaving more “wild,” feeding far less on lead-free carcasses provided to them. Nearly three decades of monitoring data show the birds venturing farther from release sites, into areas where lead-bullet bans and public education may not be as strong.

– More wild-pig hunting may be contributing to rising lead exposure. As wild-pig numbers increase and more are shot, condors may feed on abandoned carcasses containing bullet fragments. Just one contaminated meal can be lethal to a condor.

– Lead poisoning remains the top killer, underscoring the need for continued protections. In the central and southern flocks, lead poisoning accounts for 62% and 44% of deaths. 

– Using long-term data to account for changes in condor behavior, pig hunting, and other factors that contribute to lead exposure, the study concluded that outreach and lead ammunition bans reduced lead levels in condors. Without sustained outreach and enforcement, hard-won gains in the recovery effort could stall or reverse.
