Synthesis
Strategies for red wolf
recovery and management
Jonathan G. Way
Abstract
Hinton et al. (2013)
provided an important and timely review upon the 25th year of recovery efforts
for the reintroduced red wolf Canis rufus population in north-eastern North
Carolina. They concluded there were three main issues affecting red
wolves requiring continued research: hybridization with coyotes Canis latrans,
inbreeding, and demographic issues stemming from human-caused mortality.
red wolf
Herein, I add some suggestions to improve red wolf recovery efforts, focusing on management strategies: (1) perhaps most importantly, establishing a core canid conservation area where all Canis (i.e. coyotes and wolves) are protected throughout the three red wolf recovery zones, and better protection of all Canis outside that region. Due to lax state hunting laws, this will require greater protection of all Canis inhabiting the recov-ery area; (2) while I agree in principle to conserve a representative population of red wolves (which will be facilitated by suggestion #1), it is also important to recognize that hybridization between closely related species is a natural process which may promote preservation of red wolf genes by ensuring that their DNA is represented in wild Canis populations where pure red wolves may not actually live (i.e. outside the recovery area); (3) recognizing that red wolves would become more outbred if mated with closely related species or subspecies, such as the eastern wolf Canis lycaon.
eastern coyote(coywolf)
Suggestion #1 would likely help maintain a wolf-like animal within the core recovery area, and outside that area hybridization could be allowed to occur. Potential genetic restoration could occur if eastern wolves are introduced to the inbred red wolf gene pool. I conclude by offering eight strategies for conserving red wolves; many of these ideas can also be used to facilitate eastern wolf recovery in the Northeast United States.

Glad as heck to read someone else doesn't have such an aversion to hybridization--my views EXACTLY! I find the whole adaptive(and NATURAL) process FASCINATING! I've always wondered(especially with these modern examples of hybridization among native American canids), if the long extinct DIRE WOLVES were ever a part of the mix, lo, back during the Pleistocene?....L.B.
Would like to think a little "Dire" was infused into the wolf/coyote lineage
