Late Winter?

Out Like a Lion? 



Greater Lowell Technical School teachers, Tara Alcorn, Bryanna Hawkins, Kim Febres walked through light snow at Harvard Forest on March 10th.

The promise of an early spring seems to have evolved into a winter wonderland in mid March.
Frigid Temps have swept through New England, with a forecast of a major snowstorm for tomorrow.


Maple researcher Joshua Rapp has updated his observations of Maple sap timing to show that 2017 is following a similar pattern as the past 5 years, as of last week. 





Slower flows this week as the trees took their time thawing out from below zero temps last weekend. With the thermometer dropping again it looks like the sap will be locked up for the week to come as well.

Early Spring? Yes and Maybe...

Skunk Cabbage by Sally Farrow, Drumlin Farm, Lincoln, MA


The awareness of early spring struck me almost literally in mid February as was skiing in Quebec through a thunder and lightning storm in pouring rain.   This was certainly not what I expected to find after months of preparing for skiing hut to hut through the "normal" below freezing  conditions northwest of Montreal in winter.  Rain in Quebec was not out of the question, as I had encountered rain in Quebec city in February years ago, but thunder and lightning, really???

Upon my return to New England on February 25th, I was greeted with 60 degree temps, and my Facebook feed and email inbox were reflecting a bunch of unusually early signs of spring.



Earliest snowdrops ever. Sighted in the hilly wilds of West Hawley, MA on 2/25/17!

Aside from these casual observations,  here are some more scientific reports:



Definitely worth checking out an article and new set of scientifically backed maps produced by the USGS-led USA-National Phenology Network that shows just how unusually early spring is arriving in the United States.   


To see some specific examples of phenological changes occuring in Spring in the Northeast, check out: 



Back at Harvard Forest, researcher Joshua Rapp is busy collecting and measuring Maple syrup.  

This is what he's been finding since Feb. 18th about early spring harvest: 






This year I tapped the maples at Harvard Forest on February 18th and collected the first sap on the 19th, near the median day for the season start day around here. While the season started at the 'normal' time, the start of the season was anything but normal - 60 and 70 degree temps in the first week started the sap gushing and in less than 2 weeks have collected about half as much sap as we typically do in full season, and about the same amount as we did last year by this date even though last year's season started more than 2 weeks earlier. 

The colder temps predicted for the next few days will push the pause button for sap flow, but next week looks to be excellent sap flow weather again. The big question is whether the early season warmth foretells an early end of the season. If the season goes to the end of March as is typical, sap volumes may rival the high mark of 2013. If it ends early sap and syrup production may be more typical.

Stay tuned,
Josh

Silver Maple by Sally Farrow
Drumlin Farm, Lincoln, Ma. 

The skunk cabbage is blooming by preschool pond , the silver maples and pussy willows are blooming in Boyce field.

2/25 I heard peepers calling and 3/1 I heard and saw wood frogs in preschool and Ice pond.
The ponds have refrozen but there is a gentle rain and I hope for some movement tonight
Happy Spring!

Excerpt from Early Spring; An Ecologist and Her Children Wake to a Warming World by Amy Seidl: 


While I have spent time in regions of the world where global warming is more rapidly affecting ecosystems, I want to emphasize the changes I see in my landscape close to home-in my garden, in local woods, and ponds. It is in this everyday context that I notice the world entering flux.  The timing of seasonal events, for instance, is shifting:  lilacs are blooming earlier; gardens remain prolific well into fall, and butterflies appear weeks earlier than previously recorded....and the the start of maple sugaring rarely begins in early March as it historically did.... 

   With each year I am compelled to ask: How are natural communities and ecosystems where I live responding to climate change?  What does a thunderstorm in January signal?  ...As these events collect, I a realize how more and more of my observations reflect the predictions that climate scientists are making for New England-greater single precipitation events, warmer nights, shorter winters, and overall more variable weather.  While it remains difficult to draw casual relationships between global climate change and local weather, we are able to see how our local conditions increasingly resemble the forecasted predictions.*

* pages XII and XIII in Preface, Early Spring; An Ecologist and Her Children Wake to a Warming World.



So Are We Having an Early Spring This Year or Not? 

Certainly we are seeing signs of an early spring on most fronts this year, but much of our phenological observations are not complete yet. We hope that over a thousand students will begin observing study trees and recording the state of the buds to report to Harvard Forest soon.  Buds, Leaves and Global Warming Project Ecologist, John O'Keefe, has indicated to us that spring phenology is highly variable based on his 27 years of observing timing of the emergence of leaves. He has seen that local weather in the key months of March and April seem to be the largest drivers of timing of leaf out.  So while the mild spell in February has helped swell the buds on many species, we won't know about the timing of leaf out until we actually see the leaves emerge...and then there is always the chance that a late frost could kill those early emerging leaves, so the jury is still out on early spring for our local trees.  Please get out and start recording some data to track it for us, and we will look forward to hearing back from you soon.

Early Spring by Amy Seidl, Goodreads review and links 

 I recommend this book highly to those who want to explore this topic further.
 While the author is an ecologist, she writes in a highly accessible way that
 is engaging and ultimately relatable.  Very relevant to our Buds, Leaves and
 Global Warming Schoolyard project.

A Valentine for Those Who Love Trees



Getting To The 💗  Of What Drove Us to Do This Work 


I hope you will indulge me in taking some time to go back to the basics, and look at the feel good mission of this work in engaging students in Schoolyard field investigations.  In seeking the images that most inspire me about this work, I wanted to create something simple to share with you all in hopes that somehow it  can express the heart of all this work we do.  Knowing that you all share a love of trees or at least are all contributing to cultivating a love of trees in the over 3,000 students participating in our ecology projects this year, my daughter and I made this Tree Love image with the Pileated Woodpecker and Gray Squirrel  especially for you all. Mega gratitude to all of you who make up this very large team of folks contributing to our Schoolyard Ecology projects.  


Fifth Grader, Lillian Maxwell from the Petersham Center School designed the image above as a poster for the statewide Arbor Day poster contest. Some of you might recognize it from a previous blog.  It fit so well into my Love of Trees theme, I had  to include it here.  



When asked at school last year to think of one special place to evoke in 3- D, my daughter chose to create a sculpture of the Sugar Maple tree that holds her swing in our backyard.  
  

I  wonder  what forms the love for trees that your students or other children in your life are developing is taking? 

What forms is your own love of trees taking?  Please send me any images or words that show this.

Hemlock Happy

Fifth Graders from northern Massachusetts are happy about what they are seeing in their study of Hemlock trees.




Toy Town Elementary School Students have  collected 7 years of field data for the Harvard Forest Schoolyard Ecology Woolly Bully and the Hemlock Woolly Adelgid Project, led by Ecologist, David Orwig.  They are among a network of students throughout Massachusetts, New Hampshire, and Vermont helping to monitor the spread and impact of this tiny insect which is currently causing major changes in New England's forests. Toy Town students have not seen any adelgid in Winchendon as of yet, which indicates the hemlocks they are monitoring are still healthy.  Many hemlocks from Connecticut to southern NH, Vt. and Maine are not so healthy, as the adelgid is capable of sucking the life out of these sometimes giant trees.

Excerpt of Toy Town Elementary Fall 2016 data from Harvard Forest Schoolyard Ecology database

Toy Town Field Site in Red above, among Schoolyard Ecology Network field sites














Students are working in partner pairs to measure the new growth of the sample branches to the nearest .10 of a cm..  They double check their measurements and record them on their Data Collection Form.  Then we average the new growth for each tree and submit the data in the Harvard Forest Database.

-Toy Town Elementary School Teacher, Anne McDonald


 

The students also make observations about what they observe around the tree.  We discuss what species might grow in place of the Hemlock tree, if it were to die. *


 





In the classroom, we study the life cycle of the adelgid, and the attributes that make the adelgid invasive.  We also look at other invasive species and find commonalities.  Finally, we look at ways we can prevent the spread of invasive species and how we can inform others! *










Teacher, Anne McDonald, integrates activities from Project Learning Tree and other sources in order to deepen the understanding of the impact of invasive insects on the ever changing composition of our local forests.  










Toy Town Elementary Fifth Graders visit Lake Dennison and Otter River State Parks each year in the Fall to enhance the Forest Ecology unit.   



 

We Hike the MacKenzie Trail...observe and record our observations in Coniferous and Deciduous areas. *





 Students come back into the classroom and draw their observations in detail.  They identify the layers of the forest and the Producers, Consumers, and Decomposers in them. We also practice identifying leaves.

Data Workshop in Review


18 Educators from Mass., Vermont and New Hampshire, gathered at Harvard Forest  on December 15, 2016 to  learn how to work with Schoolyard Ecology Data




Dr. Betsy Colburn Introduced Looking at Data 

  • It was great to hear where other people are with citizen science and to see that I have done some good work and that I have great areas for expansion of all of this too. I liked looking at examples of graphs with Dr. Colburn and talking about how we all interpret them. .
  • It created a great mindset for the importance of data and the stories they can tell.
  • It is always wonderful to learn something new that you can use immediately. And I liked how some of the participants talked about data being a story. I will use that in my practice.
  • Just seeing other ways of presenting the data helps me bust out of my fixed point or line-scatter plots





 Dr. Emery Boose introduced beginning Schoolyard Teachers to Data Management and Input




  •  Dr. Boose did a wonderful job starting from the beginning and being very patient and clear.
  • I especially enjoyed the importance placed on making copies and keeping track of metadata. This is an important step to stress with students as well.
  • I wish could have started entering data sooner in the day.
  • Needed more time working with my data.

Harvard Forest Staff  Mentored Teachers in Working with Project Data 








          •  I was supported fully.
          • It was very nice to have such experts on hand.
          • Thank you for having so many ready to help out!!!!
          • We had a great time together.
          • Matthew was terrific helping us interpret our own pond data and instructed us on using pivot tables to create graphs. Excellent!
          • All were incredible patient in giving us the tools to communicate science effectively to our students.
          • Everyone is sweet, kind , responsive and professional.







  • I learn best by hearing, seeing, doing, messing up, fixing and shouting "yeah!"
  • It helps me to see the exercise being done and to walk through it with a mentor helps be understand the process.
  • It was very valuable to have time to "do the work".
  • I was happy to have time to work on google docs and google sheets. I identified that I definitely need more practice manipulating data in this way.




----------------
  • Today was very helpful since I practiced making graphs on excel and really did not know how to do that before today. I also worked with my own data and that was very helpful to work on making graphs that can help my students interpret the data from our school.
  • boy, did I ever graph!
  • I was able to get wonderful guidance entering my data and beginning to use the graphing tools on the websites. I simply ran out of time and would have loved to ask more question about graphing.
  • I enjoyed hearing about the different graphing techniques and seeing the presentations from Betsy and Emery. I also enjoyed talking and sharing with other teachers over lunch.
  • I tackled Google sheets for the first time - and had it crying "Uncle!"
  • I never did this before so the practice was so helpful
  • It was great to have time to do this work not isolated at school but in a community of like minded teachers and expert ecologists. In addition, I am very grateful for the ecologists taking the time to patiently explain.
  • I have realized how much I need to learn about working on google sheets. This is a good thing, especially because this is the spreadsheet system available to students at my school and I am glad to know I need more practice before I introduce it to them.


  • we already are, we will continue. They will presenting the story of their tree to their classmates next week!
  • I think I will certainly show them graphs and other representations of the data. I'm not sure I will have them analyze data this year.
