An Overview of Hemlocks<\/h3>\n\n\n\n

Hemlock trees are evergreen conifers that are widely distributed across Massachusetts. They\u2019re a long-lived tree, reaching up to 300-350 years old. You can find all sorts of critters thriving near hemlock trees, such as Red Efts<\/a> (Eastern Newts in the middle stage, the \u201ceft\u201d stage, of their three-part life cycle) and Brook Trout<\/a>.<\/p>\n\n\n\n

Hemlock trees are our natural allies when it comes to adapting to impacts from climate change<\/a> by buffering increasing storm events, providing shade from extreme heat, and even regulating water temperature and quality.<\/p>\n\n\n\n

But these trees also need our help to combat the threats they face because of climate change. Eastern hemlocks are currently under attack by an invasive, sap sucking insect called the Hemlock Wooly Adelgid<\/a> (HWA). Cold, hard winters typically lower the survival rates of HWAs, but climate change-induced milder winters are making more habitats suitable for these voracious bugs. The HWA can take down one ancient hemlock in as few as four years.<\/p>\n\n\n\n

How can we Help?<\/h3>\n\n\n\n

By conserving land! Land conservation<\/a> provides a wide array of services that help us, wildlife, and plants tackle the climate crisis. Protecting land preserves natural allies in our climate fight like hemlock trees, which not only help us adapt to climate impacts, but also mitigate climate change by soaking up excess carbon dioxide in the atmosphere. We need your help to maximize the climate impact of land conservation \u2013 join us in our collective climate fight by supporting one of our current, urgent land projects<\/a>. You can make a difference.<\/p>\n\n\n\n

Here were some questions we received about land, hemlocks, and climate change:<\/h3>\n\n\n\n

1. How will climate change impact the prevalence of different tree species in our forests?<\/strong><\/p>\n\n\n\n

As temperatures warm, trees can become stressed \u2013 which makes them more susceptible to pests that can now find suitable range where they normally wouldn\u2019t. These threatened trees will degrade, which can consequently degrade wildlife habitats. We might also see a \u201cchange of guard\u201d as a result, where tree species more tolerant and resilient to climate impacts will emerge or expand in the face of those that are more vulnerable.<\/p>\n\n\n\n

2. What is being done to reduce populations of the HWA?<\/strong><\/p>\n\n\n\n

Some universities have looked into different pesticide applications that impact the wooly adelgid\u2019s life cycle, targeting different stages. However, since pesticide use in forest settings or at the scale necessary isn\u2019t the most feasible to tackle our HWA issue, looking at other strategies (like beetles that eat the HWA) will be important as we navigate how to maintain healthy hemlocks in our environments. In fact, Massachusetts has released at least two, Sasajiscymnus tsugae<\/em> and Laricobius nigrinus<\/em> (both beetles), to deal with HWAs.<\/p>\n\n\n\n

3. How do I get into the land conservation field?<\/strong><\/p>\n\n\n\n

Olivia started her journey through the SCA, or the Student Conservation Association<\/a>. They place students into internships around the country. Another way to get involved is through state programs, like the Department of Conservation and Recreation<\/a>, or federal programs like the US Fish and Wildlife Service<\/a> or US Forest Service<\/a>. Another way is the Conservation Corps<\/a> which does fieldwork across the country.<\/p>\n\n\n\n

Tune in Next Time<\/h3>\n\n\n\n

If you didn\u2019t have time to submit your questions, you can ask away in the comments below. We\u2019ll be back the first Friday of every month for Climate Action Instagram AMAs. Visit our Instagram Story<\/a> in October to learn more and submit your questions for the next round.<\/p>\n\n\n\n

In the meantime, if you\u2019re looking for more ways to ask questions, talk about, and learn about climate change, register for our climate caf\u00e9 Climate, Community, and Connection<\/a> on September 29, 5:30-6:30 pm. You can also attend the Climate Change and Human Health virtual webinar<\/a>  on September 24, 7:00-8:30 pm via the Discovery Museum, where we\u2019ll join Dr. Jay Lemery of the University of Colorado to talk about climate change\u2019s public health impacts.<\/p>\n","protected":false},"excerpt":{"rendered":"
