You Asked, We Answered – Land, Hemlocks, and Climate Change

Last week, Olivia Barksdale, Mass Audubon’s Conservation Restriction Stewardship Specialist, journeyed into Rutland Brook wildlife sanctuary in Petersham to talk about land, hemlock trees, and climate change.

An Overview of Hemlocks

Hemlock trees are evergreen conifers that are widely distributed across Massachusetts. They’re 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 (Eastern Newts in the middle stage, the “eft” stage, of their three-part life cycle) and Brook Trout.

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

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 (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.

How can we Help?

By conserving land! Land conservation 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 – join us in our collective climate fight by supporting one of our current, urgent land projects. You can make a difference.

Here were some questions we received about land, hemlocks, and climate change:

1. How will climate change impact the prevalence of different tree species in our forests?

As temperatures warm, trees can become stressed – which makes them more susceptible to pests that can now find suitable range where they normally wouldn’t. These threatened trees will degrade, which can consequently degrade wildlife habitats. We might also see a “change of guard” 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.

2. What is being done to reduce populations of the HWA?

Some universities have looked into different pesticide applications that impact the wooly adelgid’s life cycle, targeting different stages. However, since pesticide use in forest settings or at the scale necessary isn’t 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 and Laricobius nigrinus (both beetles), to deal with HWAs.

3. How do I get into the land conservation field?

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

Tune in Next Time

If you didn’t have time to submit your questions, you can ask away in the comments below. We’ll be back the first Friday of every month for Climate Action Instagram AMAs. Visit our Instagram Story in October to learn more and submit your questions for the next round.

In the meantime, if you’re looking for more ways to ask questions, talk about, and learn about climate change, register for our climate café Climate, Community, and Connection on September 29, 5:30-6:30 pm. You can also attend the Climate Change and Human Health virtual webinar  on September 24, 7:00-8:30 pm via the Discovery Museum, where we’ll join Dr. Jay Lemery of the University of Colorado to talk about climate change’s public health impacts.

Saving Sibley

When you’re in the business of protecting land as we are, we’re often sending out requests for help. And when it came to the Sibley and Warner Farms property in Spencer, you heard our calls loud and clear. On Monday, June 4, we permanently protected the 350-acre property for conservation, farming, and public use, for all time!

What’s so special about this land? The former Sibley and Warner Farms make up one of the most spectacular undeveloped properties in central Massachusetts. Its rolling hayfields, upland forests, and wetlands offer clean water, productive farmland, and an abundance of wildlife, including otter, beaver, fisher, waterfowl, and songbirds.

Many people know the property from hiking the Mid-State Trail, hunting its woods, snowmobiling the Snowbirds trail, or just driving past and admiring the beautiful view of the pond and hayfields along Route 9.

The property seemed lost to development forever when developers won approval for a shopping center and 300-unit condo development in 2005. But then the economy turned down, the bank foreclosed, and suddenly the land had a second chance.

Along with our partners (Town of Spencer, Greater Worcester Land Trust, and Common Ground Land Trust), we needed to quickly raise $2.91 million. A tall order, for sure. But thanks to over 400 generous donors, the residents of Spencer, the Massachusetts Landscape Partnership and Agricultural Preservation Restriction Programs, and enthusiastic 7th and 8th graders from Central Tree Middle School in Rutland, we met our goal just in time. Now the land is safely and permanently in the hands of the Greater Worcester Land Trust and Mass Audubon.

Since June, we’ve barely had time to catch our breath. We’ve been busy preparing plans, obtaining permits, and beginning construction on the new parking and trailhead on Greenville Street that will serve not only the Sibley and Warner farms but also as the new main entrance to our Burncoat Pond Wildlife Sanctuary.

The dilapidated buildings on the site came down over Labor Day weekend; trails are being improved and meadows mown. And plans are well underway for our big celebration on Sunday, October 14, at 2 pm, which is open to all. Email us for details on the event and to RSVP.
