Hey guys-
I just got a response email from Mr. Shivik (mammal coordinator for the DWR) he has given me the condensed version of the proposal...I will post it below. (Thanks to him for taking the time to give me a "simplified version", it is appreciated)
Zeke, excellent question!! I will find out today.
As background, we are trying to balance hunter opportunity with minimizing bear conflicts with protecting the resource. ??Three things that are often contradict each other.
?
Also, it is very difficult to accurately and precisely estimate the number of bears in the state, but we actually don't need to.? We can manage for the 3 things above by using proxy measurements that we can record accurately:? % of females and % of adult males harvested.
?
Here?s the reason we watch % of females and adult males.? Adult males get out earlier and move around more than females.? Thus, in the spring, males are more available to hunters than adult females. They are more susceptible to harvest.
?
Based on this fact and research that was done in Idaho, we know that if populations are hunted lightly we will see high proportions of males and low proportions of females in the harvest.? Essentially, in a lightly harvested population, there are many surplus males moving around, and they get harvested.
?
Alternatively, if a population is hunted liberally (heavily), then the proportion of females will be higher. ?There are fewer surplus males relative to females.
?
As for the way we increase and decrease hunting pressure:
?
Dates of hunts may be extended, and we may raise permit numbers or add harvest objective hunts in areas where there is a history of nuisance issues (livestock or campgrounds and residences) and where we want to have fewer bears.? These are units that are managed in a liberal way, and we watch the proportions of adult males and females as indicators.?
?
An important point about timing is that later in the spring, females get out and about as much as the males do.? Thus, the longer a hunt goes on, the more females roam, and the more susceptible they are to harvest. ?You?ll see units with extended spring hunts due to human conflict with bears and the desire to put a little more hunting pressure on that local population.? That is why we sometimes extend season dates.? An extended season quickly results in higher proportions of females harvested and makes the unit more liberal.
?
A harvest objective hunt sounds more complicated than it is.? It means we have a set target (quota) of bears that we want to have harvested from the unit.? It also means there can be many people hunting on the unit at the same time.? This is in contrast to a limited entry, which as a set number (limit) of people that are allowed to enter the unit to hunt.? In a harvest objective unit, tags are over the counter and they remain valid until the quota is met.? The system creates more opportunity for people because there is no long waiting period to draw, and it should increase the efficiency and intensity of harvest by getting more people out for a short period of time.?
?
We will experiment with 3 types of harvest objective hunts this year.? The first is a regular quota, where we shut down the hunt when a specific number of bears are harvested.? The second is a split, which starts as a regular limited entry hunt, but then becomes a quota if the target number is not met during the limited entry portion.? The last is a female sub-quota, where we monitor the numbers of females harvested too, and either shut down the hunt when the total target number of bears is achieved, or when a smaller target of females are harvested.? Again, it is about proportions of females harvested in this case.
?
We are not certain which type of harvest objective hunt will be the best in the long run, so that is why we are trying three types now.
?
I hope that I've been able to explain a 37 page plan and several pages of specific recommendations in a little more than one page.? If you need further explanation or detail, please don't hesitate to email or call me.? My cell is (801) 520-0145.
