Disassembled Lake City shelters on 4/1/24, and Escanaba AND Rhinelander shelters on 4/2/24. Todd decided NOT to bring the trailer to haul back the shelter pieces but will pick them up in the next month. Did not take down Hancock shelters due to an unexpected snow storm. Recalled G5R3 logger was not locked and did so on 4/4. Not sure when it was unlocked, but the logger box door was also unlocked, units seemed fine. Neither Kevin or Sven recall leaving this unlocked. Nothing missing. As Sven mentioned on 4/2, we sampled soil at a few plots in Rhinelander for Ashim Datta.

RF407 radio on G10 116 was not working at escanaba. I moved it to 119 and it did not work there either. Took the radio back for repair.

Replaced Battery on the weather station at Escanaba

KK, DW, SB, TM, CR disassembled the four shelters at at Escanaba and four shelters at Rhinelander. Replaced weather station battery at Escanaba and Rhinelander. Took samples for Ashim at Rhinelander.

KK, DW, SB, TM, CR disassembled the four shelters at Lake City. Stack two shelter sets on one pallet. Todd and Chris will pick up later and return. We removed R1G5 10 and 25cm sensors in the under shelter and ambient plot. Left the remainder for removal another time.

Replaced Weather station battery at Lake City.

MLE species composition in Lux Arbor, Michigan South (MS). Two transects through the fertilized portion and 2 in the unfertilized. Stopping every ~1m to identify and measure the height of the first intercepted plant. - Alyssa, Evan, Gloria, Helen, Rick

Removed flags and chambers from Martha’s study on the north baitcrop area BCSE.

Additionally, removed all shelters on the Lux Arbor marginal land site. Three reps show high stress. Also, deer pellets in three of the four sheltered areas. ALOT! Only deployed one set of RH/T sensors in rep four this year.

Lake City Bulk Density cores at all plots 0-4” and 5-9” depths. Shelters moved into winter positions and screws deployed. Checked all loggers G5r2 121 SN 43047, G5r1 127 SN43040, weather SN37075, G5r3 125 SN43043. Checked rain gauge. Some labels were missing, written on core or cap. Possibly sampled a few on an earlier trip with Ashim. Removed RH/T sensors around noon.

Sampled bulk density at all Escanaba plots 0-4” and 5-9” depths, 2” wide slide hammer sampler AMS, Inc. Checked all loggers G5r1 116 SN42921, G10r3 119 SN43039, G5r2 120 SN43044, 38603 weather station. Removed all shelters by noon. Removed RH/T sensors. Checked rain gage

MLE species composition in Lake City, Michigan Central (MC). Two transects through the fertilized portion and 2 in the unfertilized. Stopping every ~1m to identify and measure the height of the first intercepted plant. - Alyssa, Evan, Gloria, Helen

MLE species composition in Escanaba, Michigan North (MN). Two transects through the fertilized portion and 2 in the unfertilized. Stopping every ~1m to identify and measure the height of the first intercepted plant. - Alyssa, Evan, Gloria, Helen

Sampled Rhinelander all plots for Bulk Density. 0-4” and 5-9” depth cores (2” wide). Also sampled bulk soil at 22 plots, both depths. Soil was rocky so we used a drain spade shove for this portion. Filled in all holes. Checked data loggers and recorded SNs. SN 38838 weather station, G5r1 126 SN43048, G5r3 124 SN43041, G5r2 118 SN43042. Checked rain gage. Filled in all holes.

Sampled all plots for bulk density. 0-4” and 5-9”. One inch spacing is due to the non-sampled portion of first core. That one inch is discarded. Checked all loggers and recorded SNs. G5r4 128 SN43046, G5r3 129 SN43045, G5r2 122 SN43049, SN 38839 weather station.

MLE species composition in Rhinelander, Wisconsin Central (WN). Two transects through the fertilized portion and 2 in the unfertilized. Stopping every ~1m to identify and measure the height of the first intercepted plant. - Alyssa, Evan, Gloria, Helen

MLE species composition in Hancock, Wisconsin Central (WC). Two transects through the fertilized portion and 2 in the unfertilized. Stopping every ~1m to identify and measure the height of the first intercepted plant. - Alyssa, Evan, Gloria, Helen

Lake City Shelters removed by Kravchenko lab R1 3:00PM R2 2:45PM R3 3:25PM R4 3:40PM

Set fallen HOBO sensor on t-post at Lux Arbor MLE switchgrass site (block 3?). Sensor remained about 1m off ground while collecting previous data (unsure when sensor fell over sideways). Now is upright, approximately 20-30 cm above switchgrass. Inside shelter sensor remains solid.

• 7/17 - Lake City with Dave and Ashim to collect bulk soil samples at 0-10 and 10-25cm using a 2” sampler and slide hammer (at all sites). Bulk density will be collected in early fall.
• 7/18 - Escanaba and
• 7/19 Rhinelander and Hancock. Rhinelander soil very rocky and dry, will need to finish R3 and 4 Bulk soil and bulk density.

Changed battery at weather station Rhinelander. Changed PAR and Solar Radiation sensor at Lake City and Escanaba. Dave installed RH/T and two shelters each at Lake City and Escanaba., Calibration images saved here.

Rhinelander and Hancock bulk soil sampling KK, DW, AD. Three 0-4” and 4-10” cores per plot. All holes filled. All plots sampled.

Sampled all plots for bulk soil at Rhinelander and Hancock MLEs. Three cores each of 0-10cm then 10-25cm below. Each core was taken in a one meter square area, one step north of the plot centerline. No more than two meters in the plot (from side) Cores were collected about .5-1 m apart. Holes filled with soil just outside or at the edge of the plot. Took approximately five hours. KK, DW, AD. 2” core samplers. No bulk density. G5 cores taken 7 steps just outside the reserve area. All collected in +N. New battery at the weather station in Rhinelander. We broke two samplers at Rhinelander and stopped bulk soil just prior to finishing R2. All poplars sampled. Used a drain spade to sample at R3 and 4 in Hancock. Created an approximately 4” diameter circle, then inserted spade 10cm and popped up soil. cleared hole, repeated in the 10-25cm depth. Worked very well and was quite fast. Filled in holes when completed.
