How are the growing zones in the United States shifting, and how do these changes affect which plants can grow successfully by region?

Credit... Source: National Oceanic and Atmospheric Administration

Students in U.S. high schools can get free digital access to The New York Times until Sept. 1, 2021.

These maps show the growing zones (also called hardiness zones) for two time periods - one historical and one projected. The zones are based on the coldest temperature of the year at each location averaged over a 30-year period. Farmers and home gardeners use the zones on these maps to inform them of which plants will succeed in their area.

After looking closely at the maps above (or at this full-size image), answer these four questions:

What do you notice?

What do you wonder?

The questions are intended to build on one another, so try to answer them in order.

2. Next, join the conversation online by clicking on the comment button and posting in the box. (Teachers of students younger than 13 are welcome to post their students' responses.)

3. Below the response box, there is an option for students to click on "Email me when my comment is published." This sends the link to their response which they can share with their teacher.

4. After you have posted, read what others have said, then respond to someone else by posting a comment. Use the "Reply" button to address that student directly.

On Wednesday, April 7, teachers from our collaborator, the American Statistical Association, will facilitate this discussion from 9 a.m. to 2 p.m. Eastern time.

5. By Friday morning, April 9, we will reveal more information about the maps, including a free link to the article that included this graph, at the bottom of this post. We encourage you to post additional comments based on the article, possibly using statistical terms defined in the Stat Nuggets.

UPDATED: April 8, 2021

Globally, 2020 was tied with 2016 as the hottest year on record. These changing temperatures can affect which plants can grow successfully in an area. Some plants will now be able to grow in regions further north because it is now warmer there and some will not be able to grow in their typical regions because it is too warm. This is also true for plant pests which can now find new habitats further north over winter and attack plants there.

The National Oceanic and Atmospheric Administration (NOAA) maintains data on the annual coldest winter temperatures across the country. Based on this data, they determine hardiness, or growing zones that run horizontally across the country. Each zone has a temperature range of average minimum temperatures. For example, the range of average minimum temperatures for Zone 6, running through the middle of the country, is -10oF to 0oF. Zones in the United States range from Zone 3 in the north to Zone 10 along the southern border. Spruces, which are evergreens, thrive in Zone 3, while palm trees thrive in Zones 8 and 9. The zone for a farm or garden can help predict what can be successfully grown. Of course, there are other environmental factors that must be considered such as precipitation, soil types and likelihood of extreme weather conditions like floods, wildfires and hurricanes.

The May 29, 2019 New York Times article " As Climate Changes, So Do Growing Zones, and What Plants Will Thrive Where " includes two choropleths (see below Stat Nugget) of the U.S. hardiness zones: historical 1981-2010 and projected 2011-2040. Each is for thirty-year periods, the length of time that is used in the calculation of the hardiness zones. What do you notice about the progression of the hardiness zones in these choropleths?

In addition to helping determine where plants can be grown, the sequence of graphs answer questions about climate change. Rather than focusing on the year-to-year variability of temperature, here we see a long-term warming trend. Even since 1981, warmer winter temperatures have crept northward. Maybe this makes winters milder for humans, but local plants may find it detrimental. This is a real problem for trees, which cannot move to their customary cooler climes. They are stuck where they have planted their roots and cannot move to survive.

Here are some of the student headlines that capture the stories of these maps: "How Global Warming Has Affected Growing Zones" by Simone of Boston; "Warming Across America: Will Our Agriculture Adapt?" by Aeryn of Portland, Oregon; "Climate Change Can Have an Impact on Your Food. Here's How." by Henna of Valley Stream North High School in New York; "How is Global Warming Impacting Plants?" by DeAnthony of A-tech High School in Brooklyn and "Tropical Plants in Traditionally Colder Areas" by Abby and "It's Getting Hot in Here!" by Emily, both from Iowa.

You may want to think critically about these questions:

Find the minimum temperature measure (in Kelvin) at two meters for 35 kilometer x 35 kilometer grid boxes (6 hour forecast) for 1981 from the Climate Forecast System Reanalysis.

Repeat the above for the years 1982 to 2010 (30 years in total).

Average the 30 years (of annual temperature minimums) to produce a 30-year average annual minimum temperature.

Convert the data from Kelvin to Fahrenheit.

To the temperature data, add 70, divide by 10 and set the negative values to zero.

As seen in Steps 3, why do you think NOAA uses a 30-year average of annual minimum temperature rather than the annual average temperature?

Estimate what the average low temperature Fahrenheit is in your area. Use Step 5 to calculate your area's hardiness zone. Now, look at the hardiness zone map. How does your calculation compare to your area's zone given on the map?

By joining the USA National Phenology Network's (NPN) Green Out campaign - a citizen science effort, you can record the effects of climate change for where you live. Then, you can compare your data to comparable data from across the country. Participants record with NPN's phone app the evidence of different seasonal stages for leaves, flowers and fruit for a wide variety of trees. Your data can help decision makers develop forecast models and early warning systems for use in forest management and public health administration. Here you can see what has been learned from the 2019 data. The graphs are very revealing.

To participate in this year's campaign, download the free software, name your project and select the specific trees that you will observe. You are ready to record your observations. Then, by using the NPN's data visualization tool, you can search for the observations of the same tree types by others from across the country and over time. Are trees leafing out, blooming and fruiting at different times? How have the times varied across the country?

The next graph on global life expectancy will be released by Friday, April 9 with live-moderation on Wednesday, April 14. You can receive the 2020-2021 "What's Going On In This Graph?" schedule by subscribing here to the Learning Network Friday newsletter. In the meantime, keep noticing and wondering.

To see the archives of all Stat Nuggets with links to their graphs, go to this CHOROPLETH MAP index.
A choropleth map is a representation of quantitative variables over geographic areas, such as states or census tracts. The values are divided into ordered categories, each with a different color or pattern, and are applied to the corresponding areas.

In the U.S. Growing Zones choropleth map, the quantitative variable is the 30-year average of annual minimum temperatures. The variable values range from less than -30oF to more than 30oF. These temperatures are converted into the NOAA hardiness zones, according to the scale shown with the map. For example, minimum winter temperatures of -40oF to -30oF correspond to Zone 3 and occur in the northern regions of Montana, North Dakota, Minnesota, Wisconsin and Maine.
AVERAGE & VARIABILITY
The average is a statistic that represents a central or typical value for a data set. There are different ways to measure the center, including the mean, which is the arithmetic average (the sum of all values divided by the number of values) and the median (the middle value when all values are arranged in order). Usually when "average" is used in the media, it is referring to the mean. Averages do not show the variability in a data set. Variability describes the degree to which values in a quantitative dataset tend to vary from the average, or more generally, from each other. Variability can be represented by such measures as standard deviation, spread or interquartile range.

In the U. S. Growing Zones choropleth map, the variable is the 30-year average of annual minimum temperatures. We do not know how the thirty values are distributed including what the lowest and highest values were. It is very possible that the lowest temperatures in the thirty-year period resulted in plants not surviving.
