The Secrets of Tree Rings: What Our Trees Can Tell Us About the History of our Environment

(150-05-05-18)
Janet Sinner Endowed Horticultural Speaker Series
Saturday, May 5
9:00 a.m. - 11:00 a.m.

Alan Branhagen, Arboretum Director of Operations and published horticulture author
Brita Lorentzen, Postdoctoral Research Associate, Cornell Tree Rings Laboratory

In honor of the Arboretum's 60th anniversary and as the very first of the Janet Sinner Endowed Horticultural Speaker Series, join us to learn more about trees and time. We first learn about tree rings as children- one ring for each year of growth- but who really pays attention to these rings and why do they matter? Join Brita Lorentzen, Postdoctoral Research Associate at the Cornell Tree Ring Lab, and Alan Branhagen, Arboretum Director of Operations and published horticultural author, to learn what trees can tell us about the history of our environment! Brita will discuss her work as a dendrochronologist (a scientist who dates environmental change and archeological artifacts through tree rings), and overview her fascinating work with trees from the Midwest to the Mediterranean. You'll discover how tree rings can help scientists determine historic temperatures, rainfall, fire events, and even health of the ecosystem. Alan will share more about the ecological importance of trees, and highlight some of the historic trees at the Arboretum. You'll leave with a new appreciation for these gentle giants and what they've lived through, and a new understanding of how to help them continue to thrive. 
Limit 150, Snyder Building - Snyder Auditorium

Walking Workshop - The Secrets of Tree Rings: Discovering the Age and History of Arboretum Trees 

Janet Sinner Endowed Horticultural Speaker Series
(150-05-05-18-01)
Saturday, May 5
1:00 p.m. - 3:00 p.m.

Alan Branhagen, Arboretum Director of Operations and published horticulture author
Brita Lorentzen, Postdoctoral Research Associate, Cornell Tree Rings Laboratory


In honor of the Arboretum's 60th anniversary and as the very first of the Janet Sinner Endowed Horticultural Speaker Series, join us to learn more about trees and time. The Arboretum has innumerable trees on its 1200+ acres, some of which are massive, historically significant, or predicted to be quite old... but how old exactly and why does it matter? Join Brita Lorentzen, Postdoctoral Research Associate at the Cornell Tree Ring Lab, and Alan Branhagen, Arboretum Director of Operations and published horticultural author, on a walking expedition as they scientifically take live core samples from several significant Arboretum trees. Alan will provide historic, botanical, and ecological background on each tree, and Brita will talk about the coring process. Observe the fascinating process by which Brita is able to determine the true age of each tree, and learn more about the tree's life as she interprets the rings. You'll leave with an enthusiasm for dendrochronology (the scientific method of dating tree rings), and a better appreciation for the environmental history our trees have experienced! 
SUGGESTED EQUIPMENT: practical shoes for walking over uneven paths, and dress for the weather.

Evening Walks with Alan: Crabapples and Hawthorns

(960-05-10-18)
Thursday, May 10
6:30 p.m. - 8:00 p.m.

Alan Branhagen, Arboretum Director of Operations and published horticulture author

There's nothing better than springtime in our crabapple collection- the hill is awash with shades of pink, magenta, and creamy white! Gain a greater appreciation for these lovely trees during an evening jaunt with fellow crabapple fans. Alan will give you a botanical overview of this tree and its relative, the hawthorn, before you begin to meander through the collection. As you walk, you'll learn more about the 60+ cultivars grown at the Arboretum, the research and history behind the trees, the ecological role they play, and how to grow these trees successfully in your own backyard. You'll leave feeling refreshed, inspired, and perhaps motivated to plant a crabapple at home! NOTE: As Minnesotans know, Mother Nature can be unpredictable...that is the joy and spontaneity of nature, and of these explorations. Be prepared for the weather and a possible change of subject matter based on what Mother Nature has in store for participants during this session. Park and meet at the Wildlife Garden Parking Lot (specific directions will be emailed before the class).

Evening Walks with Alan: Pine Collection

(960-07-12-18)
Thursday, July 12
6:30 p.m. - 8:00 p.m.

Alan Branhagen, Arboretum Director of Operations and published horticulture author

Have you ever wandered through pines after a hot summer's day? The evening breeze carries the distinctive scent of the resin, and rustles through the needles... what better time to explore our nationally renowned pine collection! Alan will start by distinguishing pines from other conifers and evergreens, and why the distinction matters. As you meander through the trees, you will learn more about the geographic origins of the species, and how the Arboretum amassed such a spectacular collection. Alan's unique and engaging style will give you a new appreciation for trees, and inspiration for your landscape and future Arboretum visits. NOTE: As Minnesotans know, Mother Nature can be unpredictable...that is the joy and spontaneity of nature, and of these explorations.

Evening Walks with Alan: Oak and Nut Tree Collection

(960-09-13-18)
Thursday, September 13
5:30 p.m. - 7:00 p.m.

Alan Branhagen, Arboretum Director of Operations and published horticulture author

The days are growing shorter, the nights are cooling- we've reached the end of the summer. For us, that means bringing the houseplants back inside, winterizing the garden... for oaks and other nut trees, it means dropping thousands of seeds to grow next spring! Join Alan and other nature enthusiasts as he shares more about the distinctive botany behind these trees- what evolutionary tactic lies behind such large seeds? Enjoy an evening walk through a lesser known collection, soak in the beautiful architecture of the oaks and nut trees, and learn more about the best species and cultivars to grow yourself. Alan's unique and engaging style will give you a new appreciation for trees, and inspiration for your landscape and future Arboretum visits. NOTE: As Minnesotans know, Mother Nature can be unpredictable...that is the joy and spontaneity of nature, and of these explorations.
