Backyard Wildlife Gallery

2012-01-12T11:55:00.000-06:00

As I'm getting ready for The Garden Expo I'm sorting through some photos to use in presentations and at the booth. I decided to fix up Good Oak's "Backyard Wildlife" album. I tend to focus a lot on plants and flowers, so I thought I should have an album of the critters that these native plants attract. There are over 50 photos in it now of critters that for the most part found there way in to my own yard, but a few photos are from clients properties as well.

Here is the album on Good Oak's Facebook page. And below are a few select photos for you to enjoy as well.

Brush Clearing Before & After at Speckled Hen Inn

2011-12-08T19:01:00.001-06:00

This past week we did some brush clearing for the folks at the Speckled Hen Inn, just north of Madison. This will be the first step in restoring this open oak woodland back to health. On my initial site visit I notice a lot of conservative woodland and savanna species including: doll's eyes, red baneberry, blue cohosh, horse gentian, yellow honeysuckle, yellow giant hyssop and purple joe-pye weed. So there's a great chance for recovery of the woodland flora once brush clearing and hopefully a prescribed burn are completed. We will be working with Robert and Patricia on reintroducing more native wildflowers, grasses and sedges and probably plantings a few bur oaks in the areas where we end up with a good gap in the canopy.

So below are a couple of "before and after" photos from our first day of work on the site. Most of the brush we removed were large buckthorns, but we also cleared a handful of honeysuckle, privet, mulberry and boxelder trees. Bob will be harvesting many of the hackberries (skinny tall trees in the photo) for firewood to further open the woodland canopy.

This is the area we cleared in the morning of our first day working there. There were four of us working on site that day. Click on either image to see them in full-size, and see switch between them to see the dramatic difference!

Here is the area we cleared the afternoon of our first day on site:

Honeysuckle: Really Quite Terrible for Wildlife

2011-10-18T14:50:00.000-05:00

Clearing invasive brush is a big part of Good Oak's business. After all, most midwestern woodlands suffer from the negative effects of honeysuckle, buckthorn, multiflora rose, Japanese barberry... and others.

People always want to know why these plants are so bad for our local ecosystems. First and foremost they simply displace native plants. Either buckthorn or honeysuckle can effectively take up all of the growing space on the ground layer in a woodland, leaving nothing but bare dirt on the ground below them. They're also bad for our birds, especially migrating birds. I usually explain that both honeysuckle and buckthorn produced berries, but these berries are not nutritious for our birds and other wildlife. Honeysuckle berries for example are the nutritional equivalent of cola. Berries from native plants are more like a glass of milk or orange juice, with protein, fat, vitamins and minerals and more complex carbohydrates.

But some new studies have found that honeysuckle harms wildlife in ways I could never imagine. A study titled Invasive shrub alters native forest amphibian communities recently published in Biological Conservation found that honeysuckle can change the "forest understory microclimate", reducing the habitat quality for native frogs and salamanders. Essentially, I think what is happening is the honeysuckle kills off all the other plants so there are no ground layer plants, and very little leaf litter or duff layer either, meaning the soil and air near the ground dry out faster, which is not good for animals who need to stay a little moist all the time. The abstract of this article concludes "invasive [organisms] may affect native organisms with which it shares no trophic connection, and suggests that changes in microclimate may be one mechanism by which alien plants affect communities where they invade.

It has been known for a while that the red berries of honeysuckle (which, now that fall has come are quite visible on these shrubs in our region) can change the color of bird's plumage. Specifically a study has been done exploring the effects of eating honeysuckle berries on cedar waxwings, with an unknown effect on the mating success of the affected birds.

Now, an new study has found that honeysuckles have created an "evolutionary trap" for cardinals. In essence, consuming honeysuckle berries artificially enhances the plumage of a cardinal, making it look brighter. A bright red cardinal is more likely to attract a mate that a duller one, usually because a brighter bird is stronger and healthier. In this case however, the opposite may be true, since these birds eat more "junk food" honeysuckle berries and have territory in poor quality habitat (infested with honeysuckle)... thus tricking birds into choosing a poor quality mate!

Add to that the fact that not one but two recent studies have found that birds nesting in honeysuckle and buckthorn have less success rearing young than birds nesting in native trees. Suddenly you can what broad ranging effects just a couple species of invasive plants can have on ground layer plants, amphibians and locally nesting and migratory birds.... Basically these plants are causing damage on all levels of the ecosystem and altering natural communities in many profound ways that.

So that is why we work so hard clearing invasive brush from our midwestern woodland and grasslands. Honeysuckle flowers may be pretty in the spring, but we shouldn't trade this fleeting beauty for the long term stability of our ecosystem.

Good Oak's Gentian Guide

2011-09-12T22:05:00.007-05:00

Just in time for the fall flower season, I've put together a guide to all of the gentians of Wisconsin and Illinois. This project is in many ways a prototype, just one example of the kind of information we can relay by means of the plant database we are developing. Enjoy, and let me know what you think!

American alternatives to European lawn grasses

2011-08-31T18:15:00.000-05:00

A few years ago I was helping a friend down in Urbana get her yard going with native landscaping. While clearing out some weeds, I noticed something odd about her lawn grass in the small strip of lawn between her and her neighbors house. It was in fact not grass at all, but was a sedge! It seemed quite happy there mixed with the Kentucky bluegrass and was surviving mowing just fine. Since she is a botanist, I asked her to bring it to work and have the sedge experts there tell us what it was. Jamie Ellis from the Illinois Natural History Survey identified it for us as Carex jamsii... or lawn sedge. At first I thought he was pulling my leg, since his name is James and we found it in a lawn, but sure enough, that's what it was.

Most people don't realize that the most common landcover in our urban areas, lawn, is composed entirely of non-native plants. Kentucky blue grass (Poa pratensis) is not from Kentucky but is instead from England. The other major component of lawns, cultivars of meadow fescue (Festuca elatior) is also from Europe, as are most of our major lawn weeds such as dandelions, common plantain and creeping charlie. What a shame that so much of Americas landscape is covered with these non-native plants that offer almost no value for wildlife and very little of interest for people!

And indeed lawns themselves are often pretty pointless and wasteful landscape features. Many people have a lot of lawn that is never used for anything but to dull the blade of their lawnmower. I have blogged about this before, and so have others, so I won't go into this rant today. However, I will admit that there is some use for some lawn in a landscape. As Allison our landscape designer says, it makes for good "negative space".

So I started thinking about using sedges as an alternative to lawn grass. Lawn sedge is an obvious good place to start, and it seems to grow well in Illinois and can also be found in southern Wisconsin, though I've had trouble finding a population local to Madison that I might harvest seed from. Another one that might work in Illinois is Caitlin sedge (Carex texensis) which Dick Young notes as "a lawn weed at Fabyan Forest Preserve surviving the mowing nicely and is more graceful, soft and interesting in the moist deep shady spots than Kentucky Blue Grass." Another closely related sedge that might work for lawn is Carex radiata, star sedge, but I don't know much about this plant yet, and finding live plants of this species for sale at a nursery is almost impossible.

Here at Good Oak World Headquarters we've been experimenting with some more common woodland sedges that tend to form "lawns". Take a look at this lawn-like groundcover in a Wisconsin black oak woodland:

Acres and acres of Pennsylvania sedge (Carex pensylvanica)! A consistant, attractive ground cover. So I have started testing out Pennsylvania sedge and another common woodland sedge as lawn alternatives in a few small areas at HQ. The results, so far are admittedly inconsistant:

Pennsylvania sedge is slow to establish. It may take years to get a consistent carpet like the photo above. The first patch below looks pretty good, but does need some weeding at this point to keep various things such as tree seedlings and dandilions out. The second patch looks a bit more ratty, I did get a little overambitious with herbicide in this patch earlier this summer and its been dry here so I think these guys are starting to go dormant. Still, I think if I am patient they will be just fine.

Rosy sedge (Carex rosea) on the other hand has taken off so well, and so quickly, that we're almost not sure what to do with it. Even though we planted it in late June, it filled in the growing space by the end of the year by growing out and just covering the ground with its leaves. This year it was growing up as well as out, it completely hid our stepping stone path through this lawn patch. It also started to develop a bumper crop of seeds. At that point we weren't sure if we should mow it (and lose the seeds), and if so, how high. My instincts are to mow it at about 6" so as to keep the bulk of the vegetation intact while making it look a little more tidy, but my little reel mower only goes up to 2.5" and is definitely NOT up to the task of cutting long sturdy sedge blades. So we just left it alone for now and hand-trimmed around the stepping stones and edge of the patio.

So I think rosy sedge has a great potential as a lawn replacement. Unfortunately the patch you see below gets trampled a lot and I think has also been effected since we mix herbicide nearby. Also, being the end of August, its not the best time for a cool-season plant like sedges.

Another sedge that's closely related to rosey and caitlin sedge is Carex radiata, star sedge, but I don't yet know enough about it to know if it might be a good lawn replacement. A local nursery manager recently suggested path rush (Juncus tenuis) for higher-travel areas and the largely overlooked sweet grass (Hierochloe odorata). Of course, many people have heard of buffalo grass, but it is native a bit west of here and needs very well drained soil to thrive in our area. Still, we have one client we planted buffalo grass (Bouteloua dactyloides) for and its doing quite well in his sandy soils.

We honestly don't know yet how these plants will handle the stresses often put on lawns such as high foot traffic and low mowing. It seems that lawn sedges does fine with the mowing, and path rush even seems to prefer compacted soil, but the rest are thoroughly untested. Still I have a lot of confidence that we can find acceptable native alternatives to European grasses for use as lawn areas. The challenges are getting sources of seed or plants, learning the most efficient way to propagate and plant them, and getting people used to a slightly different, softer and more natural aesthetic for their lawn.

It took the lawn industry 30-40 years of propagation and propaganda to cement low-cut monocultures of Kentucky blue grass and fescue as the "standard" landscape across America. It may take us a while to change the tide so that homeowners choose something more sustainable and more... well, American.

What we need now are volunteers! We'd love to help set up some native lawn test patches with some of our friends down in central Illinois testing James's sedge and Caitlin's sedge. And we'd love some Madison area folks to volunteer some space trying out Rosy sedge, path rush, James's vanilla grass and more. Interested in trying a "greener" lawn. Give us a call!

The Battle to Preserve Global Biodiversity Starts Here

2011-08-02T09:45:00.001-05:00

We'll, its been a long time since I have posted! We've just finished our busy season so we have some time to breath, reflect, and share some ideas. I'm on a hard-earned vacation at the moment, and just today I read an article in Science Daily who's title could have been taken right out of some of Good Oak's marketing material: "Ongoing Global Biodiversity Loss Unstoppable With Protected Areas Alone".

This article goes into some pretty grim statistics and projections, that seem quite overwhelming. But I urge readers to not look at this dire forecast and be disheartened. Instead, consider it a battle cry! There may not be a lot you can do about Africa, the Amazon or coral reefs, but this biodiversity crisis is a global issue, and it is happening right here in the Midwest. In the words of Margaret Mead: "Never doubt that a small group of thoughtful, committed citizens can change the world. Indeed, it is the only thing that ever has".

So lets start by restoring all of our woodlands, grasslands and wetlands to a more natural state that can harbor the biodiversity of our regions. At the moment, most of our "natural" areas (on both private and public land) hold only a fraction of the native species that belong there. We can't rely on state parks and natural areas to be the only places where we conserve our local biodiversity.

And really, there's a lot we can do in our back yards, front yards, school yards, city parks, roadsides and field edges. Our fine natural areas will need the support of a larger network of corridors and patches of native wildlife in order to preserve our unique and fascinating local biota for future generations. Every little bit you can do will make a difference!

Its Garlic Mustard Pulling Season!

2011-05-16T22:49:00.000-05:00

Perhaps May should be Garlic Mustard Awareness Month? With this agressive invasive species just beginning to flower in southern Wisconsin, its clear to see that it is taking over large parts of our landscape. This biennial weed has two unfair advantages over native plants First, it stays green all winter, so in the absence of prescribed fire it can gather resources in late fall and early spring and get a head start on native plants. Its others secret weapon is chemical warfare: garlic mustard releases chemicals into the soil that kill soil fungus. Our native plants rely upon these fungi in a symbiotic relationship in which the fungus help the plants extract nutrients from the soil and the plants provide the fungus with energy in the form of sugars. Without these fungus native plants are weakened and unable to compete with the invading garlic mustard.

We can turn this first advantage into a disadvantage by herbiciding them in late fall and early spring when native plants are dormant, and by applying prescribed fire which kills seedlings and weakens (and sometimes kills) overwintering rosettes. But by mid-May when the garlic mustard begin to flower, the best advice for most people is to PULL! Take a look at the video below and learn more about identifying and controlling this invasive plant.

Just wrote an angry letter to the Arbor Day Foundation:

2011-03-23T11:01:00.000-05:00

Dear Arbor Day Foundation,

I recently received a mailer from your organization promising 10 free Colorado blue spruce along with membership. I live in Wisconsin, not Colorado, and blue spruce are not native here as they are in the Rocky Mountains.

Your organization claims to promote conservation and wildlife preservation, yet continues to push non-native trees for landscaping and "conservation" projects. Your distribution of non-native trees ignores the critical need local wildlife have for native plants to provide the resources they need for survival. For example native trees not only provide cover, they also provide fruit, seeds, and host to the local insect species which are the foundation of the diet of songbirds and other wildlife.

For example, you have a picture of an eastern bluebird on your mailer. Eastern bluebirds favored habitat is oak savanna and open oak woodland. How will Colorado blue spruce trees help reestablish this habitat type for the bluebirds? In fact, the bird is landing at its nest hole, in what appears to be a bur oak, bringing to its young a caterpillar that was undoubtedly plucked off of an oak or other native tree. Certainly ANY tree can provide SOME resources for wildlife, but native trees provide a considerably wider range of resources for our local wildlife.

Please do not contact me again until you can offer me hardy Wisconsin oaks, or other appropriate trees native to my region.

Sincerely,
Frank Hassler

Biodiversity loss: grossly underestimated and directly effecting our health

2010-12-10T21:49:00.000-06:00

The loss of biodiversity is a issue that concerns me greatly. My desire to preserve the amazing native plants and animals of the midwest is the reason I started my business. As such, couple recent articles in Science Daily have caught my attention. The first, Ecological Effects of Biodiversity Loss Underestimated, discusses how the complexity of an ecosystem can unwind as even a single species is lost. It describes how many animals, particularly invertebrates can be "picky eaters" and require different food sources at different stages of their life. If one plant species is lost from a community than several species of insects may go with it, leaving fewer food resources for the larger vertebrates that most of us think of as "wildlife".

This loss of species means we end up with a simplified ecosystem, and these simplified ecosystems will inevitably become unstable without the natural system of competition among various species providing checks and balances. The article, Loss of Species Large and Small Threatens Human Health, Study Finds, explores the direct effect this has on people, such the increased transmission of infectious diseases like Lyme's disease.

So recent research is building the case for the importance of preserving ever scrap of biodiversity that we have. Every plant and animal species is important, and we are today, right here in the midwest, loosing some species, particularly insects, before we even knew they existed. Other such as "common" prairie plants we take for granted even though their populations are roughly 1% what they once were, with a corresponding loss of genetic diversity within these species. The only way to stem this lost is to preserve and especially to restore natural areas and to re-create new ones where they have previously been lost. That is the mission of Good Oak Ecological Services, I hope you will partner with us to achieve it.

2010-09-09T14:41:00.000-05:00

The title of this message says it all: due to an unavoidable scheduling conflict, we've had to move the Gentian Safari wildflower walk forward a week to 9 am on Sunday, Sept. 12th.

Enjoy the brilliant blues of our wild gentians, and if we're lucky we'll find a few ladies tresses orchids in bloom too. Meet at the parking lot for the Grady Tract section of the UW Arboretum at the southeast corner of Seminole Highway and the Beltline frontage road.

"Can't miss!" keynote speaker at UW Arboretum conference next weekend!

2010-09-06T10:55:00.000-05:00

Next Sunday, September 19th the UW Arboretum will be hosting its annual Native By Design native landscaping conference. I'm extremely excited to hear that this year's keynote speaker will be Doug Tallamy, author of Bringing Nature Home. This is one of the most powerful and inspirational books I have ever read. I place it up on the high mantel shelf along side the works of Aldo Leopold, Rachel Carson and Edward Abbey. This is a unique opportunity to hear Dr. Tallamy speak here in the midwest that should not be missed by anyone interested in natural areas management or landscaping with native plants.

The conference runs from 8:45 to 4:30 next Sunday. In addition to Dr. Tallamy's keynote, there will be a tour of the Arboretum's own native plant garden and several other workshop sessions to choose from. For more information, see the UW Arboretum's website.

Roadsalt: toxic to our streams

2010-09-02T20:26:00.000-05:00

Here is an interesting article on Science Daily that follows up on my previous post quite nicely. Essentially, we put so much salt on roads in the winter that the run off kills organisms in nearby streams. So please, only salt your driveway and walkway when absolutely necessary. Careful shoveling can remove most of the frozen wet stuff that turns into slick ice, snow blowers are less effective at scraping every bit off of the ground. Also, if you have the opportunity to be involved in the planning stages of a building project, site the entrance on the south side where sunlight can melt most of the hazardous ice away. Lastly, work with your city or township to encourage reduction in the use of salt on roads. Often it is just plain wasted. Other times there are less toxic alternatives like sand, beat juice and cinders.

Clearing Some Air about Herbicides and Toxicity

2010-08-26T22:10:00.000-05:00

I am working with a client now who is very worried about the impacts of herbicide to the environment. Herbicides are commonly used in restoration to kill invasive species and other weeds. They are so critical to our work; ecological restoration on any meaningful scale would be effectively impossible without them. Yet we are all aware that these chemicals are toxic and can have a real detrimental impact to the environment.

Here is an interesting article from the University of Florida Extension that makes the point that herbicides are of relatively low toxicity compared to many chemical we come in contact with every day. Take a minute to give it a read. Done? OK, well they do make some good points, but bear in mind that this article only discusses the acute toxicity (short term effects) of these chemicals to mammals (here rats serve as stand-ins for humans). So in most cases you're more likely to live if you drink herbicide than if you drink bleach or down a bunch of Tylenol. Even table salt will kill you faster than a few of these herbicides.

While this article does briefly address the long-term impacts of herbicide, such as the Agent Orange disaster in Vietnam, it largely ignores the often unknown long-term impacts these chemicals might have on human health. For example, a child probably isn't going to be killed by eating lead tainted paint chips, but it is well documented that their long-term mental development will suffer. This important impact is simply not well addressed by the way most herbicides are tested. This article also fails to mention that 2,4-D, the component of Agent Orange inevitably contains some carcinogenic dioxins as a result of the manufacturing process. Sure, there is a lot less dioxin than in Agent Orange proper, but considering that (according to Wikipedia) 2,4-D is the most commonly herbicide used in the world, perhaps we should be a little concerned.

So this is good information if you're just passing out these chemicals at your next cocktail party, but what about their effects on the rest of the environment? Sure, its relatively safe to drink glyphosate, but we wouldn't go spraying Mountain Dew or bleach all over a pasture or crop field. Who knows what the impacts would be to insects, birds, soil organisms and the fish downstream from this field? Would our groundwater become contaminated with caffeine (with the accompanying day-glow yellow color)? Even good old table salt can make soil unable to support (most) plant life.

We know herbicides are dangerous, and there are likely many negative impacts that we are just not aware of. Yet we need them to get our job done; they are valuable and effective tools. For example, the above mentioned client has a lot of buckthorn, honeysuckle, autumn olive and some of the more aggressive native shrubs such as sumac and poison ivy.

These plants are having several direct negative environmental impacts. First, they are reducing the habitat quality for other plants and animals. The effects range from suppressing herbaceous plants that provide food for insects and birds to blocking out the sunlight to such an extent that oak seedlings cannot germinate. If things keep going as they are, 50 years from now this historic oak-hickory woodland won't have any oaks in it.

Another environmental impact is the erosion resulting from the dense shade under these non-native plants. The steep hillside this woodland is on has a LOT of bare soil, and is clearly eroding away. The silt from this hillside then moves downstream and silts in our wetlands and streams, killing native wetland plants and animals and encouraging algae blooms and the nasty invasive reed canary grass.

This sounds pretty bad, and clearly something must be done to rectify this situation! (Sadly this site is typical of most woodlands in the Midwest.) The solution is to kill off the invading brush (and herbaceous plants like garlic mustard and Japanese hedge parsley) and allow native vegetation to recover (or push it along with some interseeding).

Shrubs, by definition, resprout readily when they are cut to the ground, so in order to kill this invasive brush we have to herbicide the stumps or repeatedly cut the resprouts down every few weeks for a couple of years until the energy stores in the roots are exhausted. The latter is feasible if you have just a few invasive shrubs, as is probably the case in most residential yards in the midwest, but in a 1.5 acre woodland, cutting those hundreds, maybe thousands of stems again until those shrubs all die would triple or quadruple the project costs. Meanwhile, in the short term at least, we would be exacerbating the erosion problem and impact to native plants as we repeatedly visit the site and scour the entire area finding every re-sprouting bush to cut down again.

While we'd be happy to have the work, I think the increase in the cost of the project would put it out of the means of most landowners. If we do our brush clearing work in the winter when the ground is either frozen or covered in snow, we can nearly eliminate the erosion impacts caused by our work. Furthermore, if we're careful with the use of herbicide, we could have very little "collateral damage" to surrounding plants. We use glyphosate whenever it is feasible because this chemical is easily diluted by water (such as snow) and breaks down in the soil fairly quickly, so it's not around to impact plants, insects or soil organisms, or even wash away and accumulate in our streams and wetlands.

Even in cases when we are spraying broadcast herbicide to kill off weeds on a site before we seed in a prairie, its easy to see that the short term impacts of herbicides is a lesser environmental evil than the alternatives. Consider the regular, long-term application of herbicide to crop fields or well (overly) manicured lawns. Or alternately, the incredible benefit to wildlife that a prairie planting has compared to a rough lawn, pasture or weedy pasture.

Ecological Restoration work is like a doctor working on a critically ill patient. We know that the radioactive chemicals used in chemotherapy are dangerous, but if they can kill the cancer and allow the patient to recover and return to health then they are a most necessary and critical tool needed to save a life. Our natural areas are in critical condition too. We need to carefully and consciously apply herbicides as part restoration work so that we can restore health to our natural areas for the wildflower, wildlife and innumerable ecosystem services they provide. Herbicides are toxic, but maybe aren't as bad as we sometimes think they are, and certainly better than the alternative.

Now Taking Order for Fall Plantings

2010-08-11T14:32:00.002-05:00

Most people don't realize that fall is a great time to start a new planting. The plants have enough time to get established on the site and so they get a head start on any planting started the following spring. Also, you usually have fewer weed problems with a fall planting since they don't have time to get established in the fall. Whether you'd like us to do an installation for you or if you'd like to purchase native plants from us to install yourself, get in touch with us now so we can have everything ready to go when the weather starts to cool off and its time to start planting.

Better Lawns and Gutters Tour is coming this Saturday!

2010-08-11T14:31:00.003-05:00

The Better Lawns and Gutters Tour, presented by the Dane County Office of Lakes & Watersheds is a great opportunity to visit properties incorporating rain gardens, native landscapes and other ways to 'retain the rain' and keep our lakes and stream clean. The tour runs this year from 9 am to 1pm this Saturday, August 14^th. Get started at the information center at Brandt Park in McFarland (just off of US 51 on Siggelkow Rd.). For more information, follow this link.
