A 1-day workshop attended by 12 scientists led to a decision to warm 1 hectare of forest.
A 1-day workshop attended by 16 scientists led to the design of the infrared warming, the group also made the decision to change to a 20 meter diameter circle above canopy site. And our PIs Molly Cavaleri, Tana E. Wood, and Sasha C. Reed agreed to write a white paper and literature review on the topic of warming experiments.
In Rio Piedras, PR a 3-day workshop was organized and attended by 10 scientists. At this meeting the site search began, and the three PIs shared their white paper and literature review with the rest of the group. Design and cost were also discussed.
Tana E. Wood, Sasha C. Reed, and Molly Cavaleri wrote a review paper and various other publications.
Met with program managers at different agencies (NSF, USFS, USGS) to set the basis of the project and get feedback on the proposals.
Organized symposiums at international meetings.
The US Forest Service accepted the main proposal.
A meeting at USGS Powell Center resulted in a successful proposal.
USFS funding continued through this year.
A NASA/DOE proposal was funded.
Experimental plot area was selected near the USFS - Sabana Field Research Station.
Design development for plot infrastructure was initiated.
Power upgrade began at the Sabana Field Research Station. And the new electrical sub-station and control panels were ordered.
The first soil collection for microbial analysis and bulk density was performed.
Our canopy plant physiology work started.
The first project manager was hired: Aura M. Alonso-Rodriguez.
Experimental plots construction began. (Photos)
Minirhizotron sampling tubes were installed in collaboration with Rich Norby from Oak Ridge National Laboratory.
Bruce Kimball configured the heaters and set up the understory weather and datalogger station. Infrared thermometers were also installed at each plot to help monitor the treatment.
Pretreatment field work campaigns were executed to characterize the site.
New sensors were installed: sap flow sensors; in collaboration with the team from Oak Ridge National Laboratory.
The canopy access tower was constructed. (Photos)
A pre-treatment soil core campaign was performed.
Litterfall baskets were installed, routine sampling began with the collection of point and surface lysimeter samples, our first interns were hired, and our website was built.
Our first PI meeting and soil core campaign post-treatment was executed.
Our plant physiology team performed a successful warming experiment campaign in the canopy tower.
On the 1st anniversary of the warming treatment, hurricanes Irma (Sep 6, 2017) and Maria (Sep 20, 2017) traversed Puerto Rico. The experiment was on the ground and had to pause for some time.
Adaptation and reconstruction work began after the hurricanes and the experiment had a new concept afterwards: the team was provided with a unique opportunity to study the combined effects of warming and hurricane disturbance.
A post hurricane data collection was performed to capture the event.
Reconstruction of the experimental plots was completed.
Our second project manager was hired: Megan Berberich.
A new DOE proposal was funded.
WARMING WAS RESTARTED!! (2ND-YEAR)
A project coordinator and plant physiology technicians were added to the team.
The Long-term Ecological Research Network (LTER) science council visited our experiment.
A new NSF proposal was funded.
The Next Generation Ecosystem Experiments (NGEE-Tropics) visited our experiment.
A new plant physiology technician and general field technician were added to the team.
We hosted our first school visit.
Soil Pits opened during Oct 2019 were instrumented with oxygen sensors, & temperature and soil moisture probes.
The Covid-19 pandemic strikes but our routine work has not been interrupted.
