NEARC Fall 2015 has ended

Welcome to the technical sessions schedule for the 2015 Annual Fall NEARC Conference. 

 The technical schedule is capable of being sorted by date (i.e, Monday, Nov. 9) or track (i.e. USGS Hydro). You can also search for a presentation title (i.e. Harmonizing the NHD and WBD Datasets in Maine), key term (i.e. NHD), or presenter last name (i.e. O’Neil-Dunne). The sort and search functions can be found on the navigation panel on the right side of this page. If you hover over the "Schedule" button, you’ll also see different schedule view options (i.e. Grid or Simple). Try selecting each of them to see which view you prefer. 

MY SCHEDULE FEATURE: It is not required of you to create a Sched.org account to use this site but if you do so, you’ll be able to use the "My Schedule" feature which allows you to create your own schedule for the conference. Click the "Sign Up" button in the top right corner of this page to create a Sched.org account.

Over the past 200 years the New England landscape has experienced profound changes resulting from settlement, forest clearing for farming and reforestation. This large-scale forest regeneration offers researchers a unique opportunity to examine, in fine detail, shifts in vegetation species composition, growth rates and morphologic structural changes. Forests in Central Massachusetts were studied using historical air photos, field vegetation surveys, dendrochronology samping and Geographic Information System data. 45 plots were surveyed and analyzed for variation in forest regeneration and species abundance. Results were compared to historical surveys conducted by Harvard Forest researchers on colonial witness trees. The analysis showed a decrease in species diversity but increase in growth rates over the 20th century.
