NWA 12/12/14

A Northwoods Almanac for 12/12-25, 2014   by John Bates

Ski Trail Seeds – Ash and Birch
Mary, Callie, and I have been skiing or snowshoeing every day in this wonderfully snowy winter, and we consistently see yellow birch seeds and white ash seeds on the ski trails. The birch seeds look like tiny three-fingered mittens or little fleurs-de-lis, while the ash seeds look a bit like tiny canoe paddles. The birch and ash trees appear to have had a banner seed year, and our wintering birds will be the beneficiaries.
            Both species drop their winged seeds in the winter, an adaptive design intended for the seeds to land on hard-packed snow where the wind will skitter the seeds far away from the parent tree. If the snow is soft, well, all bets are off – the seeds won’t get far.
           
Juvenile Loon Migration Update
In my column on 11/14, I’d mentioned that scientists had captured and radiomarked 17 juvenile common loons on lakes scattered across Minnesota and Wisconsin. Five of the seventeen loons radiomarked were from lakes in our area: Clear Lake, White Sand Lake, Upper Gresham Lake, Tomahawk Lake, and Butternut Lake (Forest Co.). I noticed the juvenile loon from White Sand Lake was no longer on the USGS internet map, so I contacted Kevin Kenow, a research wildlife biologist for the U. S. Geological Survey, to see if he knew what happened to it. Here is his reply:
“The White Sand juvenile evidently has bent the transmitter antenna and the locations for this loon have been few and far between. Consequently, we removed 107277 from the Loon Migration webpage. I receive temperature information from this loon from single transmissions every few days, but not enough information is transmitted to estimate a location. I know he made it to the Gulf of Mexico off the Florida coast and probably arrived near Florida on about 19 November. The radiomarked juvenile loon from Butternut Lake is another loon for which we seldom obtain a location, but I still get occasional temperature data (we will probably remove 107274 from the website as well).”
As of 12/5, the map shows that the Lake Tomahawk juvenile is off the northeastern coast of Florida; the Clear Lake juvenile is off the southwest coast of Florida; the Upper Gresham lake juvenile is off the far western edge of the Florida panhandle in the Gulf of Mexico; and the Butternut Lake juvenile has made it only so far as the border of Kentucky and Tennessee.

Snowy Owl Update
As of 12/1, we stand at 72 snowy owls in Wisconsin this year, compared to 22 by this date last year.
Cindy and Chris Wills from Presque Isle saw two snowy owls on 12/7 at the Superior Middle School, one perched on a snowbank and the other perched on the edge of a sidewalk, overlooking a frozen pond. Cindy sent me photos – it’s remarkable how well snowies blend into a hill of snow!


Sightings – Goshawk and Moose
Kaye Oscar sent me some great photos of a juvenile goshawk eating a wild turkey in her back yard. I don’t know if a goshawk is capable of taking down a bird as large as a wild turkey (a goshawk weighs 2 pounds, a turkey 9-16 pounds), but goshawks are well known to take ruffed grouse.
Sondra Katzen also sent me excellent photos of a young bull moose crossing Oxbow Lake in Presque Isle on October 10. She noted, “It was amazing how fast he swam across the lake.”

Celestial Events – Geminid Meteor Shower and Winter Solstice
            The Geminid meteor shower is at its maximum on the late evening of 12/13 and early morning of 12/14. Best time to watch is before the moon rises around midnight. Peak numbers can be 50 meteors per hour.
            Winter solstice occurs on 12/21. We now begin the slow turning towards more sunlight and longer days, a welcome, very welcome, change.

Thoughts on the Deer Hunt
            The 2014 9-day gun-deer hunt had the lowest kill in 32 years. Here’s the breakdown on the gun-deer harvest:
Total bucks: 90,336
Total Antlerless: 101,214
Total: 191,550
The total number is down 15.5% from 2013’s total of 226,582. The buck harvest was down 8%, and the antlerless harvest was down 21%. Note that the totals don’t include the harvest by archers and muzzleloaders, which may increase the numbers by 25 percent or more.
The lower numbers were expected, and here’s why:
1-    The deer population is down after two consecutive tough winters. 2014 had an estimated 1,182,000 deer compared to 1.4 million in 2013 and 1.5 million in 2012. Winter is THE limiting factor for deer – deer are on a starvation diet all winter. The last two long-lasting winters were the major factor in a fawn mortality this spring that was estimated at 43 percent.
2-    19 counties only allowed bucks to be shot, the largest “no doe” zone in 20 years. Thus, the antlerless numbers were meant to be way down – the mission was accomplished. Plus, there were additional restrictions on antlerless permits around the rest of the state.
3-    Rain and fog throughout much of the state on opening weekend made for difficult hunting conditions.
4-    In the northern counties, our early winter brought deep snow, so it was hard to get far into the woods. And then melting conditions occurred on opening weekend, flooding some of our forest roads, further limiting truck, ATV and snowmobile access. Hunters I talked to gave up early.
5-    The season started late – the rut was nearly over.
6-    In the central and southern counties, there was more standing corn than normal, making hunting on farm fields more difficult.
7-    Baiting and feeding deer continued to concentrate deer on private lands.
8-    Fewer licenses were sold – down 4% from last year.
9-    We have an increased array of predators, with very high numbers of coyote (40,000-50,000), bears (about 20,000), and bobcats. However, wolf numbers are down to 600-700 in 2014 (estimated 800 in 2013 and 1,000 in 2011). Predators move deer away from obvious feeding areas, making hunting over bait less successful.
10- Predators and bait make deer more nocturnal. Trail cameras show deer are using many areas, but only during the night.
11- Some say the aging forest is a factor since deer do better in younger forest habitats. But actually, there’s still plenty of good young habitat in most northern counties, so this is generally a non-factor.
Adjoining states also all have seen declines in their deer populations and in their harvests. Minnesota’s harvest was down 22% to 110,000 deer. Iowa has had a 33% drop in deer numbers since 2006. And while Iowa’s and Michigan’s numbers aren’t in yet, both states are saying their populations and their harvests are well down. The U.P. harvest was particularly low due to having 40 inches of snow on the ground.
Given all of the above, it was clearly expected that the largest decrease in buck harvest would occur in the northern counties – the harvest was down 18% from 2013.
Until recently, it should also be remembered that Wisconsin legislators and DNR had worked hard to bring the herd down since 2000. The 2000 harvest was 442,581 by gun hunters in 9 days, and 528,494 for the year, an all-time record. That wasn’t the good old days. That was the time when a seedling tree or an herbaceous species stood very little chance of ever growing. And the cascading impacts on many other wildlife species were equally severe.
As for hunter success, in 2000, it was 76%, compared to 40% in 2013, a number that may be lower yet this year. But again, note that in the 43 years from 1966 to 2009, the average success rate for gun hunters was 37 percent.
Unfortunately, deer biologists are again the target of blame for this year’s low harvest, despite all of the above data. Individuals who make these accusations continue to forget that the DNR does not manage deer in order to set record kills. The DNR is legislated to manage for a balance of habitat for all species, for overall biological integrity. Deer are but one among a tribe of species.
I love deer, but no more than I love the rest of Wisconsin’s wildlife and plantlife. Thus, I perceive low deer numbers in a positive light. I see the results every day when I walk in the woods – the reproductive success of trees and shrubs and wildflower is significantly up. White pine reproduction in the understory of our sandy soils is robust, in large part because of the decrease in deer, which eat five pounds of buds every day in the winter. The difference can most easily be seen when someone erects a deer exclosure, which totally excludes deer. However, deer belong on the landscape like every other species that God and evolution have blessed us with – they just can’t be so numerous that they become a detriment to the overall floral and faunal diversity of our forests.
I’m cheered by these lower numbers and have little quarrel with the DNR’s management. However, the time will soon come when our winters warm again and deer numbers rebound. Then, the DNR will again have to cut deer populations, undoubtedly using doe permits and “earn-a-buck” measures to get the job done. The wrong-headed hue and cry will rise again against the DNR wildlife managers, and the irony will be that anomalous winters like the last few we have experienced are highly unlikely to continue in this era of climate change. These winters will instead be remembered by us old-timers as the last real winters the North saw. Deer will become ubiquitous because the winters won’t be limiting anymore, and like back in 2000, we’ll have most people pounding on the DNR to reduce the herd, not increase it.
Taking the long view, perhaps we should enjoy these hard winters and low deer numbers – very different scenarios will soon enough be upon us.

A Christmas Thought – Contemplate the World with Awe

            Only when one comes to listen, only when one is aware and still, can things be seen and heard. Everyone has a listening-point somewhere. It does not have to be in the north or close to the wilderness, but some place of quiet where the universe can be contemplated with awe. - Sigurd Olson
