Historic urban grasslands include greenspaces of historic value designed for passive and active recreation in the human built environment. Urban grasslands such as cemeteries and parks present unique challenges to landscapes designed in the early anthropogenic-influenced natural world. These grasslands now exist in a time of unprecedented environmental and social pressures that often require resilience that test the limits of infrastructure and maintenance.

The results of 14 years of monitoring ash mortality and forest ecosystems in Ohio and Pennsylvania show how EAB has impacted these landscapes. Rare “lingering” ash trees have been identified and studied to understand long-term survival prospects for ash. Integrated pest management strategies, including breeding of ash trees with tolerance to EAB, show promise in management of EAB.

We will explore how researchers from ecology, forestry and arboriculture have utilized biomechanics to understand how trees contend with the forces mother nature can throw at them during their long-life span. Biomechanics approaches integrate biology and engineering principles to explore how organisms deal with their environment. We will explore two studies that examine how loads move through a branch union/fork.
Laurel wilt is caused by Raffaelea lauricola, a fungal pathogen transmitted by the ambrosia beetle Xyleborus glabratus. Dr. Albert 'Bud' Mayfield will be giving a general overview of the introduction, range and impact of and possible management strategies for preventing the spread of this disease.
Communication during the COVID-19 Pandemic—Tips and Strategies for the Environmental Education Community
This webinar explored how we should be communicating internally and externally during the COVID-19 pandemic. How to best communicate with our staff, members, supporters, funders, boards, and families focused on home-schooling.
Tree planting can help communities achieve many resiliency goals such as cooling heat islands, reducing stormwater floods, and building neighborhood cohesion.
Questions about tech? This is a power-packed session covering live vs. recorded modalities of delivery, who's using what tech, and how are you dealing with accessibility issues like closed-captioning for those without tech access.

Tree health and risk is heavily influenced by the health and quality of the soil surrounding it. Soil provides trees with essential nutrients, water, support, gas exchange, and more, but these services are limited when, for example, soil is compromised through pollution, compaction, and limited root volume.
The USA-NPN brings together citizen scientists, government agencies, non-profit groups, educators and students of all ages to monitor the impacts of climate change on plants and animals in the United States.
The Association's Education Community presents Engagement Techniques during COVID-19, led by Kristie Webber, Chicago Botanic Garden.
