Especially in the wake of emerald ash borer, urban foresters have stressed species diversity as an important goal in the management of local trees. Now there is a new, intuitive way of tracking species diversity by simply counting how many species it takes to make up half of your community’s trees.

This metric is called the top diversity index, or TD-50 index, and was proposed in a 2022 article in Urban Forestry and Urban Greening by Natalie Love and others. The index is deceptively simple — by counting the minimum number of species it takes to comprise 50% of your trees, you have an easy benchmark to improve upon to reduce your reliance on a few species.

It was 2021 and the West Allis Forestry Division faced a crisis. For all intents and purposes, its tree inventory was no longer functional. The division had always been a program that kept and used a lot of data, but inefficiencies in the inventory process abounded, and now the software where the data was stored was essentially crashing. The status quo was clearly not working.

But as Winston Churchill apocryphally said, “Don’t let a crisis go to waste.”

The annual internal audit of the Wisconsin Department of Natural Resources Managed Forest Law (MFL) Certified Group took place April 7-8 with visits to 40 certified MFL properties and completed timber harvests in north central Wisconsin – specifically, in Adams, Clark, Jackson, Lincoln, Marathon, Taylor, Oneida and Vilas counties.

An internal audit is required every year for both Forest Stewardship Council® (FSC) and American Tree Farm System® (ATFS) standards, under which the MFL Certified Group is dually certified. The audit reviews a selection of MFL properties where timber harvesting was completed within the previous three years.

Please Submit Trees Planted This Spring!

When your newly planted trees are getting comfortable in their new homes, you’ve pulled the splinters from your hands and you find yourself at a desk asking yourself, “What now?”, we have an answer for you.

Those submissions will then appear on the Tree Planting Map and be tallied toward the state’s pledge to the Trillion Trees Initiative. Governor Tony Evers signed the pledge to protect and restore Wisconsin’s rural and urban forests by planting 100 million trees in Wisconsin by 2030.
