Oakological Succession

What does the future hold for the Oak Savannas and Woodlands of Wisconsin?  I left the 2015 Oak Savanna Alliance workshop last Saturday at Camp Timber-Lee with a decidedly unsettled feeling aka, cognitive dissonance.  Am I fighting for another seemingly hopeless cause i.e., stopping the War On Drugs, or trying to get a real investigation into what happened on 9/11, when I volunteer my time and attention, my spiritual currency, to restore and preserve the oakosystems in the Kettle Moraine?  Can, or rather, should, anything be done to prevent the oakological succession of the oak forests below the “tension zone” to mixed central and northern hardwood forests?

“Oak forests on medium- and high-productivity sites throughout the Midwest have been decreasing in extent for several decades. Historically, regeneration in these forests was facilitated by a periodic fire regime. Today, it is difficult to regenerate oaks on these nutrient-rich sites due to competition from native and nonnative plants that outcompete oak seedlings. Browsing by white-tailed deer also limits the survival and growth of oak seedlings. The lack of successful regeneration along with selective harvesting of mature oaks contribute to the gradual succession of oak forests to mixed central hardwoods, which includes species such as red and sugar maple, basswood, elms, green and white ash, and ironwood.Wisconsin’s Forests 2004 United States Department of Agriculture

DNR Natural Area Conservation Biologist Matt Zine made an excellent presentation about the progress of the oak succession and the master planning process currently happening at the Lulu Lake SNA.  But it appears, given the meager crumbs of financial support they get, that the Bureau of Natural Heritage Conservation should be renamed to the Museum of Natural Heritage Conservation.  With an annual budget of around $5 million, supporting 33.5 full time employees (of which only a handful are working in southeastern Wisconsin), to manage the endangered resources on 673 State Natural Areas comprising 373,000 acres, they are hard-pressed to do more than save a few choice relics.  Matt explained that they are 10 years behind when it comes to creating master plans for all of the SNAs, and that’s excluding the SNAs above the tension zone, which presumably do not contain any endangered resources, or stand to benefit from any formal management planning.   We don’t know how many, or what percentage, of the SNAs below the tension zone have master plans. This limited perspective on our endangered resources ignores the other 5 million acres of publicly owned lands in the state as well as the privately held lands (approximately 29 million acres.)

Matt is the messenger and I’m having trouble with the message.  Am I fighting Mother Nature when I cling to the ideal of the pre-settlement oak savannas and woodlands and work to restore something that can never be again?  It’s not just the trees, it’s the oakosystems and the mystique of the Native Americans who nurtured and mastered a life sustaining and harmonious balance of flora and fauna.  I fear that, if we don’t preserve the oak savannas and woodlands, we will loose forever the native wisdom accumulated over centuries, that they intrinsically and beautifully embody.

Thank goodness there are people like Eric Tarman-Ramcheck, Emily Stahl and Amanda Kutka, who organized the Oak Savanna Alliance Workshop, and Zach Kastern and Ginny Coburn, who share my passion for the oak savannas and woodlands of the Kettle Moraine!  Zach and Ginny have been organizing volunteer workdays in the Southern Kettle Moraine in partnership with the DNR for three years now.  Zach was awarded the Land Steward of the Year award by the Oak Savanna Alliance.  Way to go Zach!

The Buckthorn Man made a decent presentation baring his heart and soul while sharing his experiences volunteering for 20 years in the Kettle Moraine.

I’m plagued with doubts as I continue my efforts at The Scuppernong Springs Nature Trail: am I doing “The Right Thing” or am I fighting the natural succession?  Is it wise to abandon the management practices of the people who lived here for thousands of years, which kept the natural succession in check?

On Tuesday May 12, I spent most of the day cutting garlic mustard with my brush cutter.  I am observing that in the areas where I concentrated on cutting garlic mustard last year, there is significantly less this year and the plants that are present are typically 6-8″ tall, spindly, and with relatively few seeds.  I am gaining confidence that the strategy of mowing garlic mustard can succeed by focusing on keeping it out of the “best” areas and then gradually expanding the no-GM zone.

The river is starting to make a head cut at the Hotel Spring bridge location where the DNR recently excavated (scroll down to the leprechaun image in this post for more details.)

The sun made a dramatic appearance late in the afternoon.

On Wednesday, May 13, I was back at it whacking garlic mustard and pulling water cress.  I also spent some time weeding the spotted knapweed from the patches of lupine that are proliferating on the west slope of the sand prairie.

On Saturday, May 16, Pati and I stopped at The Springs on the way home from the Oak Savanna Alliance Workshop to check out the lupine.

And finally, on Monday, May 18, I spent an absolutely beautiful spring day cutting garlic mustard, pulling water cress and digging out spotted knapweed.

In the late afternoon I joined Pat Witkowski and the Ice Age Trail Alliance “Monday Mudders” to do a little trail maintenance near the tower at Lapham Peak State Park.

Burn Bluff Creek East!

The Bluff Creek State Natural Area is a jewel in the Kettle Moraine State Forest–Southern Unit.  The rolling moraines, deep kettles, massive oaks and bubbling springs that source Bluff Creek, make this one of the most beautiful areas in southeastern Wisconsin.

The DNR’s SNA team has been prepping the east side of the Bluff Creek property for months creating clean, wide firebreaks all around the burn unit, which is no easy task on the steep moraines.  This would be the second time they burned the area and everyone was anxious to get it done.  Last Saturday I spent the day there with Zach, Ginny, Don, Jerry and Brandon raking the areas around dead snags and taking down some really punky ones that might have fallen across the firebreak.  We worked along the eastern perimeter of the 454 acre burn unit between A and K on the map below.

I stopped at Bald Bluff on the way home hoping I would get an invite to come back the next day for the burn.

I forgot my phone and, sure enough, when I got home, there was a message from Jared inviting me to join their crew to Burn Bluff Creek East.  Cool!

The team from the Bureau of Natural Heritage Conservation included: Burn Boss Matt Zine, Nate Fayram and Jared Urban the north and south line bosses respectively and Jessica Renley, Alex Wenthe, Adam Stone and Bridget Rathman.  Paul Sandgren, Matt Wilhelm, Don Dane, and Dennis Mclain represented the Kettle Moraine State Forest-Southern Unit.  Greg Kidd and Erin Holmes, volunteering their time, represented the NRCS (Erin also works with Pheasants Forever).  And, last but not least, Bill Walz, an SNA volunteer who also works with The Prairie Enthusiasts was there.

Matt Zine explains the burn plan.

It was a pleasure to hang out with the “pros” and be one of the team.  Matt Zine attributes much of their success developing the SNA’s in the Kettle Moraine State Forest–Southern Unit to Paul Sandgren’s leadership and commitment.  A lot of thought and effort went into planning this day — bringing the people and equipment together — and the conditions were perfect for a woodland burn!

Per the plan, we began anchoring the unit on the line between points B and A.

IMG_2639 IMG_2640 IMG_2642

Then the south line team began lighting a backing fire from A to L while the north line team did the same moving west from B to D.

IMG_2644 IMG_2646 IMG_2650

The steep moraines were not for the fainthearted to drive an ATV up and down on, and the wetlands on the northern perimeter had some deep, water filled trenches to negotiate.  I was really impressed with the fortitude and level of effort and cooperation amongst everyone involved.  They carried out the plan without a hitch!

This classic kettle required a bit of extra effort to carry fire through it.

Bill and I got “released” around 6:30pm and I quickly changed clothes and headed back to the burn unit to get some more pics.

A happy Matt and Erin.

I was eager to see the blackened kettles and moraines along the line from A to L.

IMG_2659 IMG_2661 IMG_2663

Then I headed west from point A and decided to try to walk the perimeter of the burn unit.

IMG_2666 IMG_2667 IMG_2668

I was blown away when I saw how difficult it must have been to lay down the backing fire on the north line.  Here are a couple views of the wetlands Nate, Jess and Adam lit up.

You could see lines of fire still creeping through the center of the unit.

I threaded my way through the black and brush until I came to the big open water where all the springs collect forming Bluff Creek.

IMG_2685 IMG_2686 IMG_2687

There are dozens of springs flowing into the headwaters.

It’s a good thing I had walked this area once before on an SNA workday at Lone Tree Bluff and knew where I was.  I had no problem picking my way through these creeping fires on the trail leading back to the parking lot on Easterly Road.

IMG_2693 IMG_2696

I found my way in the dark back along the firebreak at point J and came all the way around the south end of the burn unit back to point A.  And reminiscent of last year’s Scuppernong Burn, I ran into Don Dane, just beginning his all-night vigil at the burn unit.

The new Statewide Prescribed Burning Guidelines require that all burning and smoking wood on “the entire burn” be extinguished before the burn can be declared “controlled”.  Don watched the fires throughout the night and the SNA team returned today to complete the mop up.  It is hoped that the guidelines can be amended to acknowledge the low level of risk that smoldering logs pose in the middle of a huge burn unit.  It is hard and complicated enough as it is for the DNR to effectively use fire to help manage the forests.

See you at The Springs!
