Join the Discovery Center for an afternoon winter waterfall adventure.

Waterfalls in Winter - Adults
Date: Saturday 01/14/2012 10AM - 3PM



We’ll visit 4 different waterfalls from 15 to 30 feet in size and will be traveling from the U.P. to Northern Wisconsin in the Discovery Center van. While exploring the falls we’ll discuss the complex geology of the Gogebic and Penokee Iron range, which at one time was taller than mount Everest. Today, they show us the base of the mountain and the rocks are aged to be some of the oldest in the world.

Make sure to bring a camera for this winter wonderland experience.

Bring a pair of snowshoes or rent a pair at the Center.
We’ll meet at the Discovery Center at 10am and return by 3pm. 

Pack a lunch. Call early to reserve your spot, or click here to register.
 

 Admission: 
$29 ($25 Members)
Add $5 if you need to rent snowshoes

Meet at the Discovery Center. (715)543-2085

Be a Part of the Tradition!


Citizen Science in Action
The count period for the 112th Christmas Bird Count will begin on December 14, 2011. 
From December 14 through January 5 tens of thousands of volunteers throughout the Americas take part in an adventure that has become a family tradition among generations. Families and students, birders and scientists, armed with binoculars, bird guides and checklists go out on an annual mission - often before dawn. For over one hundred years, the desire to both make a difference and to experience the beauty of nature has driven dedicated people to leave the comfort of a warm house during the Holiday season.

Each of the citizen scientists who annually braves snow, wind, or rain, to take part in the Christmas Bird Count makes an enormous contribution to conservation. Audubon and other organizations use data collected in this longest-running wildlife census to assess the health of bird populations - and to help guide conservation action.
From feeder-watchers and field observers to count compilers and regional editors, everyone who takes part in the Christmas Bird Count does it for love of birds and the excitement of friendly competition -- and with the knowledge that their efforts are making a difference for science and bird conservation.

You can visit Audubon's website for the history of the bird count, bird lists, and more!

How to Get Involved Locally

Manitowish Waters- December 17th
Minocqua- December 29th

We are looking for volunteers to count birds at feeders and field observers to count birds within each of the established survey blocks.  If you live within the area you don’t even have to leave the comfort of your warm home.   It's fun and easy. If you would like to participant in this annual tradition please contact the North Lakeland Discovery at 1-715-543-2085.

Hawk Ridge Adventure

Sometimes places are cool, without having to try.  Such is the case with Hawk Ridge Bird Observatory (HRBO)in Duluth, MN.
Hawk Ridge is an outdoor overlook space, along the northern side of Duluth’s Lake Superior shoreline.  The views of the woods and Lake Superior are outstanding, and the birds fascinating.  Every year, thousands of birds concentrate in this spot during the fall migration, and thousands of people gather to view the action.  The banding, counting, and education that happen are due to the efforts of the non-profit HRBO, along with the Town and other NP partners.

The big, visible birds migrating through are hawks, vultures, eagle, osprey and harriers.  The HRBO crew count the birds, and band as many as they can.  The data gathered is sent to a centralized database, allowing monitoring figures to be used by professionals such as wildlife researchers and forest habitat managers.  So, not only is this place cool, but it’s valuable for future habitat management and can be an indicator of when something is going wrong, or right, in our natural world.

This past October weekend, the Discovery Center led a field trip to Hawk Ridge.  In September, you’ll see a greater number of smaller birds.  These birds – Broad-winged Hawks, Merlins, Kestrels, and Sharp-shinned Hawks – need to migrate earlier.  They have longer to go (Broad-winged Hawks fly to South America), and their food sources (snakes, frogs, dragonflies) are often warm-temperature dependent.




In October, the Ridge sees greater numbers of Bald and Golden Eagles, Red-tailed and Rough-legged Hawks, Turkey Vultures and Northern Goshawks.  During our visit, we were fortunate to see most of these species, and in good numbers.  The final counts for some of the key species were:
Turkey Vultures
Bald Eagles
Red-tailed Hawks
Northern Goshawk
Sharp-shinned Hawks
Northern Harriers
45
111
355
13
351
8

We did see some other species, too – bringing the total birds counted to 896, a great count for a mid-October day.  

One other really fascinating thing to witness is the post-banding release of these magnificent birds.

 HRBO has 3 banding stations where certified banders lure birds in.  Our group participated in a behind-the-scenes tour to see how this process is carried out (think pigeons, bow traps and mist nests).  Once the birds are caught, data gathered, and bands placed, they are then transported to the overlook.  The birds are handled by volunteers and staff, and information about the species is shared with the audience.  All the while, staff and volunteers encourage HRBO’s “Adopt A Raptor” program.  For a donation, people can “adopt” a banded bird.  What this means is that if the bird is found anywhere, you receive follow-up info on that bird.  What it really means is that you get to handle & release your adopted bird back to the wild.  I was the lucky adopter of an immature Red-tailed Hawk, and got to toss this bird up with everyone cheering the bird’s release and the re-start of its migration journey.

Green Fire: Aldo Leopold's Legacy in Film

This Friday the North Lakeland Discovery Center is proud to host a special screening for the first full-length movie on the life and legacy of Aldo Leopold, "Green Fire".

Friday, September 23, 7:00pm - 8:30pm.
$5 Members, $7 General Public
Click here to reserve your spot for this epic film!

View the Trailer...

The Green Fire Story

(from the Green Fire website: http://www.aldoleopold.org/greenfire/about.shtml)


“We reached the old wolf in time to watch a fierce green fire dying in her eyes. I realized then, and have known ever since, that there was something new to me in those eyes—something known only to her and to the mountain. I was young then, and full of trigger-itch; I thought that because fewer wolves meant more deer, that no wolves would mean hunters’ paradise. But after seeing the green fire die, I sensed that neither the wolf nor the mountain agreed with such a view.”- Aldo Leopold, A Sand County Almanac, 1949

The impact of his own gunshot from a rimrock in Arizona changed Aldo Leopold’s own thinking, leading to the key insight that was the culmination of his life’s work: a responsibility for its health. Join us as we trace Leopold’s personal journey and follow the threads that connect to his legacy today.

The Green Fire Film Project

Green Fire was produced in partnership between the Aldo Leopold Foundation, the Center for Humans and Nature, and the US Forest Service. The film provocatively examines Leopold’s thinking, renewing his idea of a land ethic for a population facing 21st century ecological challenges. Leopold's biographer, conservation biologist Dr. Curt Meine, serves as the film's on-screen guide.
Green Fire describes the formation of Leopold’s idea, exploring how it changed one man and later permeated through all arenas of conservation. The film draws on Leopold’s life and experiences to provide context and validity, then explores the deep impact of his thinking on conservation projects around the world today. Through these examples, the film challenges viewers to contemplate their own relationship with the land community.
The high-definition film will utilize photographs, correspondence, manuscripts and other archival documents from the voluminous Aldo Leopold Archives as well as historical film and contemporary full-color footage on location, including landscapes that influenced Leopold and that he in turn influenced.
The film also features commentary and insight from some of today’s most recognized and credible scholars and conservation leaders, including: three of Aldo Leopold’s children—Nina, Carl, and Estella, Leopold scholars, noted environmental writers, scientists, humanities experts, public policy leaders, business leaders,; and leaders of non-profit groups inspired by Leopold.

“Chella” beetles ATTACK! (We hope)…

Our ACE team of naturalists were out releasing Purple Loosestrife bio-control "Chella" beetles at Wild Rice Lake on July 21, 2011.  Bio-control is using one living organism to control another - most often a pest species.  The pest in this case is the non-native, invasive plant species Purple Loosestrife (Lythrum salicaria).  The organism used to control loosestrife in this case is an aphid (Galerucella spp), affectionately referred to as "Chella" beetles as it is much easier to say than the full Genus name!


 Anne Kretschmann and Zach Wilson (pictured) were hard at work in the midst of the heat to get these beetles out on site so they could get to work (the beetles, not the naturalists... they are always working hard!)


These highly effective beetles only eat loosestrife, weakening the plant and suppressing flowering; essential to controlling the spread of loosestrife which threaten our native plant species.

Beam Me Up Scotty!

The Discovery Center's Adventure Club (ages 9-14) has done some amazing things so far this summer- paddled a 26 ft war canoe on the Turtle-Flambeau Flowage, climbed the world's largest ski jump, explored the Porcupine Mountains- but next week's trip is sure to be the most unique.
In Monico, Wisconsin, a man named Frank Kovac dedicated ten years of his life to building a planetarium in his backyard. Not just any planetarium, but the world's only mechanically rotating planetarium.
He hand-painted all of the northern hemisphere stars visible to the unaided eye within his 22 foot diameter globe!
I'm incredibly excited to visit the Kovac Planetarium and meet this dedicated man. www.kovacplanetarium.com has the full story.

We still have spots available for this Adventure Club trip! Other activities planned for the day include swimming and geocaching.
Contact the Discovery Center (715-543-2085, or www.DiscoveryCenter.net) to reserve a place!

Cattail Fail

A recent cooking incident with some wild foraged cattails inspired me to write this phenology update.

Phenology is the study of the timing of plant and animal life cycle events. Scientists study phenology during the seasons as a means to track change. Wild-foragers, those who gather wild edibles, track phenology to learn when their favorites plants are ready to eat. In this case, I wasn't paying close enough attention to phenology!

In my family, the ripening of cattails is a major phenology event.This week, I heard from my Minnesota-dwelling cousins that they were harvesting the young flower heads for eating. I though that this week's Adventure Club, a canoe trip down the Manitowish River, was the perfect excuse for some foraging.

As our intrepid group of canoers paddled around a bend, we noticed a large stand of cattails accessible from the water. Rylie, Jon, and I set out to gather what I thought were perfect male flower spikes- covered in floppy stamens holding the yellow pollen.  I placed the flower spikes into a spent granola bar box to capture the pollen -it makes a great addition to pancake mix- with plans to boil them back at the Discovery Center.

To make a long story short, the boiled flower spikes looked pitiful and tasted horrible. Here's why it failed:

Cattail species are monoecious, having both male (pollen-producing) and female (seed-producing) flowers. The male flowers grow together in a dense cluster called a spike at the top of the stem, and the female flowers are clustered below the males in a fatter spike that looks like a hot-dog. As the male flowers mature, they grow stamens that produce mustard-yellow pollen. Eating the male flowers at this point gives an unpleasant mouthful, which is exactly what we experienced.

The key is to harvest the /young/ male spike just as it is emergering from the leaves, when it is yellow on the inside and green on the outside. Boiled and covered in butter like corn in the cob is a simple preparation.

This week's phenology update literally comes from my mouth. It appears that it is too late to eat the much-beloved male flower spikes, but cattail pollen season is here! Shake the pollen into a paper or plastic bag, sift, and add to any recipe that uses flour with a 1 part pollen to 3 part flour ratio. It adds a nutty flavor and a golden color.

Always make sure you forage from a clean environment, as polluntants can accumulate in plants. Also, be sure you have correctly identified your target species. If you are not sure, don't eat it!

Enjoy!
