One year of monitoring later

One year of monitoring later

We have just completed our first year of monitoring and established some baseline data.  In the understory, invasive shrubs and vines are growing throughout our woodlands. In areas of higher native diversity, the dominance of invasive species is lower.  In understories thick with honeysuckle there are very few seedlings and saplings. Our canopy data show a rise of red maples is happening across the property. Red maples have physiological properties that make them successful in both early and late successional stages of the forest.  Based our surveys, our oak hickory forest is being replaced by other hardwood species such as maple and beech. The large oaks and hickories close the canopy for light, and oak and hickory seedlings are not shade tolerant compared to the other species found in the woods. We will keep documenting this shift.

This diagram represents data from one of our most diverse communities (oak hickory).  Twenty six species were observed over the summer and fall seasons and the most frequent species (seen in 4/5 or 5/5 plots) are pictured.   The three invasive species observed in high frequency were chickweed, honeysuckle and winter creeper.

Lots of Plots

Lots of Plots

Dr. Pat Keyser from University of Tennessee made his second trip to Greenacres last week.  The purpose for this visit was to start laying out the research plots on the 10-acres that we set aside in Lewis Township, for the purpose of our research collaboration.  The study has 8 treatment levels with 4 replicates for a total of 32 different plots – all randomized.  In other words, it’s a fairly complex plot design to lay out across 10 acres (see picture).

To speed up the process, Jennifer and I decided to get a head start on laying out the plots while we were waiting for Dr. Keyser to arrive.  This was the first field study for either of us at this scale, so for the first several hours it was “one step forward, two steps back”.  I was beginning to question my ability to measure long distances.  Luckily, Dr. Keyser showed up in the nick of time, before we really dug ourselves in a whole – plot set up is old hat for him!

With the sun setting a little earlier these days we were able to get the corners of each plot measured off and marked (the green circles in the photo).  We will return later this week and get the rest of the plots flagged off.  After the plots are laid out we just wait until spring so we can start the planting process, starting with oats.

Heard but not seen

The past week has been a little busy in Indian Hill so we finally got a chance to do our third and final covey call count today.  It sounds like the coveys are located around one specific area so this time I didn’t want to take any chances and not hear them.  Jennifer and I split up again but stayed within sight of one another (once the sun came up) so we were both in the area where the quail were heard the first and second time.  Finally I heard it!  The covey call that had been eluding me the first two trips was just south of where I was sitting.  After the sun came up Jennifer and I both agreed on the direction that I heard the sound, however she also heard one to the northeast of where we were.  We thought we would try flushing the birds to try to see if we could get a count so we headed toward the edges of the field.  We had no luck getting the birds to flush out of their coveys but we both feel pretty confident that we at least have some quail walking about the Lewis Township property.  Now the goal is to see if we can increase our quail populations through improved habitat establishment and quail-beneficial management practices.  Call counts and quail monitoring will be an ongoing practice for our research team.  We are already looking forward to some early chilly mornings next October.

Chilly mornings in the field

Today Jennifer and I got another early start to do some covey call counts and hopefully hear the coveys that our resident bird expert Joe heard a couple of days ago.  It was another clear and chilly morning and this time I was a little more prepared by bringing a fold up camp chair.  I found out that standing still in the middle of a field in 20 degree weather can be hard on your back! With a head lamp, chair, and a thermos of hot tea, we walked back to the same location where Joe was situated on our previous visit.  We still thought it would be a good idea to split up and go on opposite sides of the tree line, hoping we could better locate the direction in which the covey calls were coming from.  I kept looking at my cell phone to be prepared for when 7:14am approached so I could be extra focused.  7:14am came and went, then 7:29am.  Next thing I know, the sun is up.  Maybe Joe didn’t hear them…or maybe it’s just me?  When Jennifer and I met back at the tree line where we separated she excitedly said “did you hear them!?”  Nope.  Well…I guess it is me.  Next time we go to Lewis Township I’m sitting right where Jennifer and Joe were located so I can get in on the action too!  Good news is, Jennifer was pretty sure it was a covey call so we’re one step closer to confirming we have some quail populations.  And once again, as you can see in the picture, it was another beautiful early morning – a great way to start the day.
