Hi Anthea,

Here's a couple of bullet points:

Peter

Changing seasonality (spring coming earlier, fall coming later) is creating complex and poorly understood changes in the forest. Can trees adapt to these changes in a positive way and make use of the longer growing season? Or will they do poorly under novel conditions? Long-term research is needed to understand this.

Less snow in the winter has the surprising effect of creating colder soils! Snow acts as an insulating blanket such that most forest soils in New Hampshire do not freeze in the winter. A lack of snow results in soil freezing and colder and more variable temperatures in the soil which is a big stress on plant roots and other organisms that live in the soil.

Happy to elaborate.

The greening season is getting longer with earlier leaf out and later leaf senescence (Hallworth et al. unpublished data).

Female black-throated blue warblers advance their timing of breeding with earlier spring leaf out shortening the window between arrival to the breeding grounds and laying their first clutch. Unclear what will happen if spring leaf out advances earlier than the first week of May, which is when this species arrives back to the breeding grounds (Lany et al. 2015).

Survival during fall migration is lower following longer greening season (Rushing et al. in prep).

Dramatic declines in forest beetle abundance and diversity are linked to reduced snow depth and shorter duration of snow cover (Harris et al., in press).

Best,
Sara

HBRF and Hubbard Brook researchers have had several successful engagements with U.S. Congresswoman Ann Kuster (NH-02) over the past 3 months.

Kuster is on the House Energy and Commerce Committee, jurisdiction including environmental protection, clean air, and climate change. Kuster plans to roll out a new climate and clean energy initiative in the coming weeks, and her team is requesting a set of current facts that describe climate change at Hubbard Brook. HBRF will organize this information into a one or 2-page fact sheet to send to the Kuster team before the end of this week.

If you would like to contribute, please send me up to 3 bullet points describing climate-related changes that your research has revealed at or in connection with Hubbard Brook. These changes could be ecological, economic, or social.

Please email me your bullet points by the end of the day on Wednesday. This is part of HBRF's rapid response policy outreach initiative.

The Congresswoman has indicated that she feels grateful to have Hubbard Brook as a trusted scientific resource in her district. Thanks in advance for taking this opportunity to share your work for informed decision-making at the national level.
