Optimizing Tree Responses to Root Pruning in Mature Trees @ 1pm Mountain
This webinar will present the results of some new research on root pruning. Three years ago, the roots of 32 mature London plane (Platanus x acerifolia) trees growing in New Zealand, were cut, either leaving a stub, or making a reduction cut, back to a side root; half were pruned in Spring and half in Autumn. Three years later, the patterns and extents of new root regrowth and decay were examined. We’ll present root response to pruning and discuss the optimum regrowth and compartmentalisation responses of these mature trees.

Identification and Management of Invasive Vine Species @ 11:00am Mountain
Vines are woody or herbaceous plants with relatively long stems. Vines are typically known for their twining or climbing nature. In the US, we have several non-native species of vines that have become problematic and are now considered invasive species. These invasive vines can cause problems such as outcompeting native plant communities, growing into dense thickets, girdling trees, and being extremely difficult to remove. But what are some examples of invasive vines that we find here in the US? What kind of problems do each species cause, and how can they be managed? In this webinar, Chris Evans will discuss the biology, impact, and management of some commonly found invasive vines.
Thursday, November 6th
Urban Tree Diversity–An Open-ended Prospect @ 10am Mountain
Can urban environments support urban tree diversity – what marks success? Join Dr. Alicia Coleman, University of Minnesota, as she discusses tree diversity and selection considerations for communities.
Tree Preservation: Compounding Interest @ 10am Mountain
Join us for the fifth session of the Tree Equity Coaching Network with Austin, TX. We’ll discuss how policy and planning is central to realizing the benefits of trees on a human timeline.
