Effects of Stocking
Statement on Stocking Pen-Raised Birds to Increase Populations
Kansas Upland Game Program
Kansas Dept. of Wildlife, Parks, and Tourism
Kansas has been in extreme drought conditions for most of 2011 and 2012. These factors have caused a decline in upland game populations through much of the state, especially pheasant populations. Upland game populations are continually cycling up and down given various weather and habitat conditions. It is often suggested that Kansas Department of Wildlife, Parks, and Tourism (KDWPT) begin stocking pen-raised birds to “help” the struggling populations. There are important reasons why KDWPT biologists will not pursue this course, and they are as follows:
• Research has shown that pen-raised birds do not survive well (some studies suggest greater than 90% mortality within 30 days or less) after initial release and a very low percentage make it into the following breeding population.
• Research has also shown that those females that do survive into the following spring have very low nest and brood success, and are not able to add significantly to the population. The cost is nowhere near the benefit.
• The only reasonable situation for releasing pen-reared birds is to release them right before a planned hunt, and the expense for a put and take program that would satisfy hunter demand across the state is astronomical and not fiscally feasible. Nor do we know the impact such a widespread release of pen-reared birds could have on our wild populations in terms of genetic change or spreading of disease.
• Our current wild bird populations have filled habitat niches across the state, and have adapted to their local habitats. These wild populations are currently cycling through the ups and downs at the natural capacity of current habitat conditions. Adding pen-reared birds will do nothing to increase current populations in the long term.
So if the above is true, then how did many upland game birds come from pen-released stock in the first place. First let’s consider the habitat at the time of release. Farming practices were vastly different in the early 1900’s when many of the releases took place. There were more weedy fallow fields, more “dirty” farming practices. These areas provided ideal habitat. Second, many thousands, even millions of birds over the years were released. It is likely that a very low percentage of these pen-reared birds survived and an even lower percent that successfully reproduced. But with ideal and unfilled habitat, their wild populations were slowly able to grow until they filled the available habitat. Releasing pen-reared birds today is like trying to put more gas in a full tank, it is just wasting valuable financial resources that could be spent more effectively. The best management practice we can do is to increase usable habitat. Upland game populations have an amazing ability to reproduce and expand given good climatic and habitat conditions. They have shown over the years they will naturally fill available habitat given time. Therefore, as a wildlife agency extremely passionate about our upland game resources we are focusing on how we can conserve what habitat we have and increase available habitat in the future. This is the best use of the sportsmen’s dollars.
