About the Field Day
This year’s New Hampshire Tree Farm Field Day is being held at The Rocks in Bethlehem NH, owned and managed by the Society for the Protection of New Hampshire Forests (SPNHF). Once the summer estate of the Glessner family, this 1,400 acre property features beautiful views, pleasant walking paths, terraced gardens, active forest and wildlife management, historic buildings, and acres of Christmas trees! It is also home to the NH Maple Museum.  

This beautiful property serves as SPNHF’s North Country Conservation & Education Center where they welcome thousands of visitors to share traditional farming and forest experiences such as making maple syrup and cutting your own Christmas tree. More than 1,450 Tree Farmers manage 500,000 acres of forestland in the Granite State.  Each year, the NH Tree Farm Committee holds a Tree Farm Field Day to celebrate Tree Farmers and to provide an opportunity to share ideas and information.

Forest Management and Wildlife Habitat Tour: We will take a walking tour along some of the well-maintained trails on the property and view a variety of practices implemented to improve wildlife habitat, create and maintain views and historic interpretation, and improve forest health and diversity. The mixture of meadow, hard and softwood forest, wetlands, and Christmas tree fields at the Rocks creates habitat 
for countless bird species. We will discuss practices to enhance early successional habitat for species including woodcock and ruffed grouse.

We will be walking on a portion of the property’s “Mile Path” originally constructed for the Estate’s city visitors to enjoy the outdoors. We will also visit several historic buildings including the Big Rock Summer House and the Bee House. This walking tour is approximately 1 mile in length, and there are opportunities to join or head back depending on your interest and walking ability. 

NH Maple Museum and Virtual Sugar House Tour: Learn about how the Forest Society welcomes people to the property and connects visitors to great traditions and outdoor experiences.  This past year, 75 buses of visitors visited the Rocks. The Forest Society will share how they have navigated the logistics of welcoming large numbers of people to their property. They will share their agro-tourism experiences about what to expect and things to consider.  

Christmas Tree Management: For the past 30 years, the fields at the Rocks have been used to grow Christmas trees.  Each year the Forest Society plants between 2,500 and 7,500 trees.  

Visit Go Green Wood Product’s Mat Log Manufacturing Facility: Visit Go Green Wood Product’s mat log manufacturing facility at 1161 Whitefield Road (NH Route 116) in Bethlehem. Directions will be provided at Field Day. The mat log market has offered landowners good opportunities to harvest low grade logs. Visit this operation to see how these logs are fabricated into mats to cross streams and wet areas without causing a lot of soil disturbance.
