TSE/CWD expert testimony
Q: Can you just generally describe the
8 status of CWD in Colorado?
status of CWD in Colorado?
9 A. Yes, Wasting Disease is now
10 established in the wild throughout the northern
11 half of Colorado. Interstate 70 pretty much
12 divides the state from north to south, kind of
13 like I-80 divides Iowa from north to south, so
14 most -- well, all of the population units north
15 of I-70 -- I'm pretty sure that's true -- have
16 had at least one case of Wasting Disease that
17 we've detected, and then there are a number of
18 units south of the interstate where we've also
19 picked up the disease, but generally it tends to
20 be more the northern half of the state than the
21 southern half.
22 Early on we truly believed that the
23 disease was focused just to Larimer County, the
24 Northern Front Range and a little bit out on the
25 Platte River into southern Wyoming, and we and
1 Wyoming and a number of other places since have
2 learned that the distribution was much more
3 widespread than we originally thought.
4 Infection rates in those herds, we
5 have places where we pick up a case and we may
6 not see another one again for a number of years.
7 The infection rates are as low as one percent.
8 We have other areas locally where, at
9 a management-unit level, where ten, 15, 20
10 percent of the harvested male deer might be
11 infected.
12 We have smaller populations that we've
13 studied. The one that we've most intensively
14 studied is in Table Mesa just on the south side
15 of Boulder, Colorado. In that population, 42, I
16 believe, percent of the male deer were infected
17 and about 20-some percent of the female deer
18 that we looked at were infected.
19 So it can be locally a very high rate
20 of infection, and even on a larger scale, it can
21 be relatively prevalent in some places.
22 Q. And what has been the impact on the
23 herd, overall herd, from the infection rate?
24 A. Overall, at a large scale, so at a
25 population level it's been difficult to
1 demonstrate any effect over the period of time.[/COLOR]
2 But we've studied the disease and
3 followed the numbers, in part because there are
4 a number of other things that influence
5 particularly deer population dynamics a lot more
6 than a disease like this would in the
7 short-term: weather events, our own hunting
8 practices, predation.
