Half-way through the summer

Today marks the halfway point for the summer. Five weeks down, five to go. We’ve accomplished a lot and much more remains. After a long afternoon of measuring plants, we had some watermelon and carbonated beverages to cool off, mark the 1/2way, and wish the Chicagoans well.

Three of our team members are leaving tomorrow for Chicago (Jennifer, Lani & Denise). They will keep us posted about the analysis of the bee-tracking field data and how it relates to their pollen flow study.

Here’s a photo of us on the porch of the Hjelm house today, just after lunch.

Excitement on the prairie

It was an exciting day on the prairie. After a soaking morning rain, it felt hot and steamy. Just before noon the plants started flaunting their pollen and the bees took advantage. There was plant sex and bee sex and Team Echinacea jumped into the fray trying to keep up with the frenzied activity. Every team-member broke a sweat trying to keep up with all the bees. It was a crazy scene and the excitement in the air was palpable. The bees eventually outmaneuvered and outlasted us, but we had a great time. We left around 12:50 looking forward to another exciting day.

Unlike most of the shy bees, this rascal loved the cameras. She gave quite a show flying from head to head, daring us to follow. We caught her here spreading pollen all over her legs.

busy day

We had a busy day today. Reinforcements arrived to help on all of our projects. Ruth Shaw (U of MN) helped with phenology, bee tracking, PX caging, collecting pollen and crossing. Elliott Graham (Madison, WI) helped with bee tracking and PX caging. Jack Kiefer (Wadsworth, IL) is leading the plumbing initiatives and made progress on several fronts including connecting the main water line to the Hjelm house!

Great forward progress on a sultry day. Well, in late afternoon it was still with air temp of 85 degrees F and a dewpoint of 57 degrees F.

Thanks to all for a great day!

Flowering Echinacea plants in the Common Garden

Less than 10% of the heads that we think will flower this season had started flowering as of Sunday. Flowering is so late this year! We’ll walk through the Garden systematically tomorrow (Tuesday) to see what’s new. It’s possible one head (49.33 946.33 grn) will be done flowering tomorrow.

There’s always something new and exciting going on when Team Echinacea is in full swing. After we all pitch in to assess flowering phenology tomorrow, Amy will work on her large-scale crossing experiment that requires erecting pollinator exclusion cages, collecting pollen & hand crossing. The fun doesn’t end there. We are tiling and plumbing the Hjelm House, photographing floral development on Echinacea heads, measuring plants at the Hegg Lake CG and the main CG, taking ladder-high aerial photography of flowering plants in the prairie remnants, and chasing bee pollinators in the CG. And that’s just tomorrow!

A lesson in punctual flowering

As is probably apparent in this recent explosion of posting, we’ve now got the Internet on the inside of the condos. Neither rain nor mosquitoes nor legions of caterpillars can keep us from our e-mail.

To demonstrate our unsurpassed powers of data transfer, I present to you…. a picture that is truly huge.

This is the most developed Echinacea head in the common garden* which is remarkable because this time of year is usually the peak of flowering, or so they say. In any case, I’ll be taking pictures of it and some of its developmentally challenged comrades every day or so. The result ought to be a number of sequences that chronicle this awkward phase in their lives, followed by their blossoming and wild reproductive successes (or lack thereof). Yes, much like the reality TV stars that they are, these plants will have no secrets!

* except maybe for the 99 garden, where I did not dare venture

Chemical Warfare

So about a week ago, Team Echinacea was counting and mapping tiny little seedlings. I was working with Gretel, and we had found a plant that apparently knew how to reproduce 47 times in one season. Yes, we mapped out 47 seedlings but not before a spray truck came along.
Because of the strong winds, we could not hear and were quite surprised when a large truck spraying chemicals on a nearby farm rode by us, emitting a putrid scent. Not wanting to breathe in chemicals, Stuart and Gretel began to yell at the spraying perpetrator: “Stop! What are you doing?!��?
The driver stopped, and we all moved upwind, away from the chemical mist. Stuart argued some with the driver who was standing close to the sprayers. Eventually, the driver realized that he was losing the argument (you are not supposed to spray people with chemicals) and drove away.
We decided to move to another spot, and on the way we saw a Bobcat (farm machine, not the animal) on fire. A bunch of cows stood around looking confused. Strange afternoon.

Hard at work

IMG_5959.jpg

Here’s a photo of the crew from the first day of the summer (Julie, Christine, Megan, Ben, Lecia & Gretel). Echinacea hasn’t started flowering in our Common Garden yet, but it will soon. We are ready! Reinforcements from Illinois will start work tomorrow.

We’ve been working for two weeks now and we have accomplished a lot already:
searched for seedlings in remnants
mowed, weeded, and flagged the common garden
searched for juvenile plants in the “recruit” experiment
discussed and planned our group and independent projects for the summer

It’s hard to believe how much we’ve done already (and how few flog entries I’ve posted).

Skink emerges from a beer can

While at eri prairie remnant searching for Echinacea seedlings we were cleaning up the beer cans from the ditches and found many ant nests under them, but on can had a surprise. Amy was shaking the can and a skink popped its head out causing her to drop it. The skink was shocked and was frozen in place for a minute with just its head and neck exposed.

Field work, May 2008

Here’s an update on the main research activities this spring. The cool spring with a late snow (~15 inches -38 cm- at the end of April) delayed burning weather somewhat and we think seedling recruitment may be later than in the past few years.

Recruitment/Establishment Experiment

On May 9 I mowed burn breaks so the DNR burn crew could burn the plots. They burned the middle unit at Hegg Lake WMA on May 28. Two plots were in this unit. Here’s a photo of one plot just after the burn. Nice work! There are 3 plots to be burned at Hegg Lake WMA, two at Kensington Duck Refuge, and one a Eng Lake WMA. At the duck refuge I saw 2 Sandhill cranes and a Red-necked grebe (among the regular, awesome array of water birds).

Common Garden

Dwight, Jean, and I burned the common garden on May 22, starting just after noon. The weather was within prescription, but the wind was a bit strong and the fire jumped the gravel road and started some corn stubble. The fire worked its way to some reed canary grass and we managed to put it out there. If it had gone a little longer it would have torched the cattails and burned the whole slough west of the common garden. Whew!

The running fire was great in the 99S garden, but there were quite a few unburned spots in the main garden. We burn the CG every other year and we mow paths annually, so we don’t have quite enough fuel for really complete burns. Maybe in 2010 we should augment the fuel load with some prairie hay.

A big tree just east of the CG caught on fire. It was hollow, but quite strong. It finally broke and fell over around 7 pm. To put it out we scraped all the embers and coal from the trunk with an axe and shovel. We couldn’t reach a spot of punky wood 8 – 9 feet (2.5 m) off the ground. So I climbed up the trunk and used a 5 lb. pick mattock to scrape out the embers and punky wood. Then Dwight lifted the smith Indian backpack sprayer over his head and I sprayed and sprayed and sprayed. We put it out by around 10 pm. Exciting! We need to cut up the part of the tree that fell on the CG.

An adult bald eagle flew over the CG just as we started to burn and then again around 8 pm — great!

On 24 May, Gretel and I broadcast seed over the CG. We seeded Galium boreale, Bouteloua curtipendula, and Schizacharium scoparium. Gretel, Per, and I seeded the ditch with many species of seed, including Stipa spartea and Spartina pectinata. We forgot to seed the 99S garden.

Seedling Search

On 27 & 28 May Ruth, Amy, Julie, and I searched for Echinacea seedlings in five remnant prairies. We searched about 75 circles with 41 or 50 cm radius and found 17 seedlings. Several had only cotyledons and the tallest first leaf was 24 mm. We got rained out yesterday (29 May). It was also cold and windy.

Hjelm house

Last weekend Pete, Dwight, Gretel, and Stuart cleaned out all the sheetrock and insulation (yuck) in the house. That was a job. We got the house all ready to have the floors sanded. We have a lot left to do to get the house ready for the main field season. The highest priorities are bathroom and computer network.

I just found out that there is video footage of the house being moved on YouTube.
