Trees and Stormwater

Davey Tree Expert Company has a calculator on their website where individuals can calculate the annual dollar value of all the benefits the trees on their property provide -- to them and to the community at large!

For example, the 39 inch bur oak provides nearly $400 worth of benefits annually, including more than $195 in stormwater management by eliminating over 7,000 gallons of stormwater runoff every year! Without that tree, all of that rain water would flow rapidly to the street, helping to overwhelm the stormsewers.

Now, when I add up the stormwater caught by all of my trees: three bur oaks, one white oak, a cottonwood, two maples, two pears, and two honey locusts, the stormwater savings alone of these trees amounts to nearly $2000 a year, or 65,000 gallons of stormwater that is intercepted rather than running off into the stormsewers!

According to the Center for Urban Forest Research, trees act as mini-reservoirs, controlling runoff at the source. Trees reduce runoff by:

- Intercepting and holding rain on leaves, branches and bark
- Increasing infiltration and storage of rainwater through the tree's root system
- Reducing soil erosion by slowing rainfall before it strikes the soil

And you know what, the trees cost us virtually nothing. Sure, we rake the leaves in the fall (which is good exercise, by the way), and pick up branches after a windstorm, but the annual cost is minimal.

This kind of information makes me think that more communities could invest in promoting city trees as part of their stormwater management program rather than (or in addition to) expanding their stormsewer systems. I would guess that it is much less expensive to manage 7,000 gallons of water with a mature tree than by building more stormsewers.

According to American Forests: As communities grow, trees are removed to make way for impervious surfaces such as parking lots, roads and buildings. Our studies show that impervious surfaces have increased by 20% over the past 2 decades in urban areas. Constructed stormwater facilities are created to compensate for the tree loss. These facilities are expensive to build and maintain. The cost has been calculated to be in excess of $100 billion nationally.

Do you have time to help TLC?

Volunteers are the heart of any nonprofit organization, and TLC is no exception!

A whole diversity of TLC volunteers attend our regular Work Parties, cutting brush, burning prairies and wetlands, collecting seed, etc. They are awesome, and their combined efforts each year are equivalent to a half-time staff person.

Some volunteers are licensed herbicide applicators, a skill that requires taking a special class and passing a test. Some bring their own chainsaws, fuel and extra blades to help cut buckthorn and other brush and trees. But they all bring their hearts and energy to the work, doing what they can to restore the Earth.

Our board members are all volunteers, and they do much more than just attend a monthly board meeting! They serve on committees, attend conferences to learn more about conservation and nonprofit management, help out with land stewardship, and basically anything else that they can do to be helpful. The picture to the right is of board members Steve Wenzel and Randy Schietzelt visiting a property one weekend to see whether it was appropriate for TLC to accept as a donation.

TLC's Oak Keeper volunteers are making important contributions to understanding the 15,000 acres of privately owned oak woodlands in McHenry County. In their first year of monitoring private woods, the Oak Keepers have already "discovered" the first two documented occurrences of natural swamp white oak trees in the county - ever. That is really cool, and it was all because of the Oak Keepers project and the work of the TLC Oak Keeper volunteers.
There are many opportunities to make your own contribution as a TLC volunteer. Whether you have a couple of hours a month or a couple of hours a day, there is an opportunity waiting for you at TLC! Give us a call today!

February is bird-feeding month!

I knew that February was African-American History Month, but only just learned that it is also "Bird Feeding Month," promoted by the National Bird-Feeding Society! (birdfeeding.org) The designation was made by Illinois Congressman John Porter in 1994, and has grown in popularity ever since.

February was selected because it is the hardest month for most wild birds, particularly in northern climates like ours. The weather is typically harsh, and food is scarce. The point of having a month devoted to raising awareness of the importance - and enjoyment - of bird feeding.

So, why feed birds?

Keep in mind that a typical backyard bird doesn't weigh as much as two nickels. They spend most of their waking hours searching for food - without the help of "hands" and "fingers". They may consume 20% of their body weight overnight just keeping warm enough to survive. Providing them with an easy to access source of nutritious food makes a big difference to these little guys!

Providing wild birds with food, water and shelter supplements their natural diet and helps them survive. A Wisconsin study showed that chickadees with access to feeders made it through a severe winter better than those without.

And feeding backyard birds is fun. It is exciting to look out and see a dozen or more birds - of different sizes and colors - hopping from bush to feeder and back again.

Here is a collection of advice and tid-bits I pulled off the Internet:

- Keep feeders full, so the birds have a dependable supply of food during cold weather.

- Keep feeders free of snow and ice.

- Offer suet, which is pure fat, a great source of energy for those backyard birds whose summer diet was mostly insects, like woodpeckers, as well as chickadees and nuthatches.

- Stamp down the snow underneath the feeders to help the ground feeding birds, such as juncos, cardinals, blue jays and doves.

- People shouldn't be discouraged if they put up a new feeder and the birds don't flock to it immediately. Because birds find food by sight, it can take a while for them to locate a fresh source. Try putting a piece of aluminum foil on the ground near the feeder, where sunlight can be reflected and catch their eye.

And bird feeding is good for one's health!

Watching wild birds relieves stress and helps one start the day on a positive note. Bringing birds into the backyard, particularly during gloomy northern winters, adds a welcome flash of color, dash of motion and splash of sound. Wild bird feeding is the principal connection many people have with wildlife, considering the continued trend toward moving out of rural and into urban areas.

So, if you aren't already a bird-feeder, now is the time to start! Advice from the experts is to start with a tube feeder, as pictured here. It will attract a diversity of birds. The Cornell University website has a wealth of information about birds and bird-feeding.

TLC's 2009 Annual Meeting a Celebration of People & the Land they Love!

About 130 people gathered at the Bull Valley Golf Club for The Land Conservancy's 2009 Annual Meeting Sunday January 25th. The audience re-elected Sandra Scheinfeld and John Sterling, and elected new board member Jim May (not pictured here!)

Two individuals were presented with the Living with Trees Award for 2008: Dale Shriver for his tireless management of nearly 80 acres of remnant oak woods that he owns, and Robert Roe for his tireless efforts to restore the fen and oak woods at Dutch Creek - all on land that is protected by a conservation easement in his subdivision, Dutch Creek Estates.

The stories of five easement donors were shared with the audience:

- Dale Shriver & Judy Rogers for their 53 1/2 acre easement on the oak woods that MCCD didn't want to buy - but they wanted to be sure it was protected. The woods, which have been there since at least 1837 when the first public land survey was done for the county, have been sustainably managed for many years. At some point in the past, the white oaks were harvested to make bowling pins! So if you find any wooden bowling pins at an antique mall, just think - they might have beem made from Marengo oaks!

- Marty & Lynn Sobczak (who were unable to attend) for the 3 acre easement they dedicated on land that adjoins MCCD property on two sides, and contains the last natural lily pond along Nippersink Creek.

- Randy & Karen Stowe and Orrin & Patricia Bangert for dedicating conservation easements on land they own adjacent to the MCCD High Point Conservation Area. Their willingness to pledge that they would donate conservation easements on their land if MCCD purchased the adjacent natural area that contains the highest glaciated point in the State!

- Phyllis & Tony Hennen (who were unable to attend), for choosing to dedicate their 25 acres south of Woodstock as a conservation easement, and donate the land to the City of Woodstock as a public natural area. Attorney Jane Collins accepted their plaque for them. Ms. Collins was instrumental in the "Stop the Stacks" Peaker Plant battle that the Hennens fought for years, even turning down a very high offer from the peaker plant company, choosing not to sell out their home. Today, their choice means that not only is there no peaker plant south of Woodstock, but there will be a public park for all future residents, forever.

Numerous green, organic, local and homemade items were available in a silent auction. Where else can you get an organic turkey, organic onions, and organic honey in addition to a hand woven-silk shawl and hand carved wooden bowls.

Personally, I'm thrilled that I had the winning bid for the Farmer John Gift Bag that includes the movie "The Real Dirt on Farmer John," a copy of the Farmer John Cookbook, two Angelic Organics t-shirts, 2 pounds of organic coffee, two jars of organic honey, a pound of worm castings to use as a soil amendment, plus a delicious collection of handmade milk soaps!

Batavia author Gina Olszowski delighted the audience with her story based on her self-published book. Gina is the youthful 25 year-old author of Coming Soon to a Town Near You: Voices of Urban Sprawl. The book combines black & white photos with excerpts of interviews with residents and public officials to tell the story of urban sprawl and the effects it has on communities.
Thanks to everyone who contributed to it being an inspiring day!

You can help track climate change!

This is the year of change, isn't it? The whole presidential campaign was about change -- President Obama's Campaign theme was "Change We Can Believe In." The theme for his election is "Restoring America's Promise," which implies that we have lost our promise, and need to make some changes to earn it back...

While there are still a few folks debating the causes of climate change, it is pretty clear that our weather patterns are changing.
Here's an example that any gardener can relate to: Portions of the Chicago region have edged up from Hardiness Zone 5b to Zone 6 according to the Arbor Day Foundation.

“The USDA map just doesn’t seem right anymore,” said Woody Nelson, vice president of communications for the foundation. [Yes, that is his actual name - Woody - and he works for the Arbor Day Foundation!] “So we took it upon ourselvesto do our own map.” For an updated take on which plants are hardy in your region, look at the foundation’s map online.

The map puts the Chicago area in Zone 6 with an average low of 0 to -10 degrees. The area is in Zone 5 on the USDA map. The foundation used data from the National Oceanic and Atmospheric Administration, the same source the USDA map uses, but the data are more recent, collected from 1990 to 2004. The foundation’s map, like the USDA’s, is a compilation of average low temperatures because the lack of cold hardiness is the most profound barrier to plant success. Plants simply can’t adapt to regions where they are unable to survive the winter.The changes were startling. Many areas jumped one or two zones higher. “The climate has changed,” Nelson said. “It has warmed.”

It turns out that we can all help contribute real world information that will help scientists understand the implications of any changes that may be happening. The citizen tracking effort is called Project Budburst, and it is sponsored by organizations ranging from the US Forest Service to the Chicago Botanic Garden. You can join with thousands of gardeners across the country in tracking when the plants in your yard leaf and flower each year.
If you are at all like me, you delight in noticing those early blooms and sprouts - whether they are chives, crocuses or dandelions! Now, you can sign up to share that information with a national network, and be part of a pretty cool "citizen scientist" project that has practical applications for folks everywhere!

Cold ... ccccold

This morning, I had a call from someone who told me that his car's thermometer said it was 32 degrees BELOW ZERO while he was driving through a rural area in McHenry County.

Okay, I grew up in the Chicago area, and remember the big snow in 1978, and the deep freeze the winter 1981-2, but this is ridiculous.

First we have snow, snow and more snow, then this brrrr cold stuff! What's up? It's almost enough to make someone a global warming doubter...

I actually saw a cartoon earlier in the week that said: "Yea, long-term I'm worried about global warming, but today I'm worried about freezing my *ss off!"

Inaugural Work Party!

Who's up for a winter work party?!

The Presidential Inauguration is going to be Tuesday January 20th, and the theme is "Restoring America's Promise," so what better way to celebrate than by attending the Inaugural Workday at our newest preserve: West Woodstock Prairie?!

The President-elect's Inaugural Committee is having a Day of Service on Monday, January 19th, the MLK Jr. Day Holiday, and encouraging people to volunteer in their communities to kick-off this new era of restoration!

It's practically a Presidential Decree! And you can be a part of this historic event by participating in TLC's Inaugural Work Party at West Woodstock Prairie!! You don't want to miss out on the fun!

Meet at 9am on Rose Farm Road, south of Kishwaukee Valley Road on the west side of Woodstock! You can park at the side of the road. Thanks to Seneca Township for clearing the shoulder for us to park on! Dress for the weather, and in work clothes. We plan to get a bonfire going to burn the brush we cut - and help us stay warm. We'll have something warm to drink and sweet things to eat!
