A few points missed in this topic:
1) Politicians do not use any science for their reasoning, they submit purely to the political pressure of the uneducated masses who do not hunt or live in the areas impacted by their decisions and political/emotional will and agendas;
2) Black bears eat more moose calves than even the wolves do, and bear numbers are also on the rise as many do not hunt bears like they did in the past - again a rise in predator populations;
3) Any place that has managed their game populations in a productive manner have done so by:
a) Managing their predators properly (mentioned above, and goes to this next point not discussed), and
b) Managing their game populations with a healthy bull;cow or buck;doe ratio - this means that older mature females should also be harvested on a regular basis to ensure that the male:female ratio remains balanced in healthy state.
It is easy enough to ensure that you are not harvesting a cow or doe that is still accompanied by a calf or fawn, it just takes more time to observe and ensure it is a lone, dry mature cow or doe - if a hunter does not take this care, nursing mothers will be taken, and if to early in the calf or fawns life cycle, they will be susceptible to easier predation when not in a herd environment. Later in the season (say November and December), the calves and fawns are starting to be weaned from their mothers milk and are better prepared to fend for themselves as they are older and stronger. When I have been in greater need of meat while hunting in the past (early 90's), I have opted for the second year calf moose, as the cow was most likely bred and would be producing another calf in the spring. Other than that, over the years, when harvesting a female moose, elk or deer, I have always taken the time to ensure I was harvesting the old, mature dry cow or doe before taking that shot.
For me, the main point here is maintaining a proper balance of predator and prey species, as well as a proper balance in the numbers of males and females in any given population, in order to realize healthy populations and good recruitment numbers.
Our moose populations here in northern BC have gone down by over 70% in the past 12 years, and the so called experts running our wildlife management have only exacerbated the problem with their changes in wildlife management, as have the politicians who make the orders, who know nothing about what they are doing and are incurring more wildlife conservation problems while trying to solve their political issues. There was a period of 5 years since 2010 that I hunted from August through to December in the South Peace region and did not even see a single bull moose; just cows and calves. I know they were there (found their tracks, droppings and rubs, and seen the calves), but they just weren't being seen. The hunting pressure here has been very high over the past 20 years and it shows, as many of the hunted species have gone nocturnal, and are not seen as often or in the numbers that they used to be seen.
