Deer and Deer Management in NYS Webinar

I have a hard time believing 2% predator impact. I don't see the benefit of even mentioning adult predation or diverting it separate from overall mortality - what that tells me is they are using numbers that they deem helpful to their cause and skimming over numbers that might be detrimental.

 

Most of the collared/fawn studies show mortality due to canines and bobcats much higher than that in even very "deer friendly" environments.

 

Predator numbers aren't the only impact on fawn mortality as it relates to predators - longer drawn out rut/actual breeding timeframes reduce the "market flood" that occurs in the ideal state for whitetails. Short, intense ruts results in more fawns being born in a shorter period of time - essentially flooding the market for predators, reducing their ability to impact fawn mortality. Fawns are at their most vulnerable during the first few weeks of their lives when their defense mechanism is to be immobile. Drawn out birthing timeframes allow predators a wider timespan to predate.

 

We all know shorter, intense ruts are more likely in herds with stronger B:D balance. Not many areas in NY are in that ideal range, meaning a strung out rut/breeding period is likely, giving predators the platform to make more of an impact.

 

Of course, this isn't talking about the 20% that come in early/late - this is talking about the bulk 80% (give or take) that come in, in November.

I haven't gone this link yet but, for those who didn't attend the webinar, this is the link they gave.

Warning - Each session was 1 hour 30 minutes long.

Other interesting information is supposed to be there too.

Perhaps it was supposed to be a 20% survival rate of fawns due to predation

 

NY also has coyote seasons- one that was shrunk and conveniently ends mid march when pups emerge from the den. You cant kill them all, but they're far more of fawn and adult deer killer. They kill what they need and sometimes what they want. The gnaw the a$$ out of living animals to return and take more but the intent is to eat living tissue. On death they may or may not come back.

Want to argue what they eat? Look at their droppings. Feeling like too many here are taking the DEC's (or antis) argument hook, line and sinker
