Updates from ASLA


Free PDH of the Month

ASLA continues to offer one on-demand webinar each month at no cost to all current members! Members must register for the Free PDH of the Month and pass the exam during the month it is featured in order to earn professional development hours.

In September, we are featuring:

The Vibrant Cities Lab: Free Urban Forestry Resources, Research, and Tools - 1.0 PDH (LA CES/HSW)

The Vibrant Cities Lab offers easy access to the best available science about the impact of trees and green space on economic development, public health, transportation, equity or water quality – eleven impact areas overall. Each impact area offers curated research, case studies, policies, and plans from around the country. Vibrant Cities Lab also offers a step-by-step guide and assessment tool to help communities make sustainable urban trees a reality. Whether in public or private practice, serving large or smaller clients, this tool is designed to help expand awareness of the benefits of urban trees, such as real cost savings (for example, reduction in stormwater management costs), and implement best practices for growing urban canopy rooted in science and proven in communities like your own.
