Caring For Our Urban Forest

Several months ago, during a presentation on a potential plan to combat emerald ash borer and work towards a new urban forestry approach, the consultant hired by the city uttered a phrase I’ll never forget.

She called South Milwaukee “the Wild West of urban forestry.” And, as you can guess, it wasn’t a compliment.

Well, we’re taking steps to shed that image – starting with $300,000 in tree removal funding and a new public tree ordinance that defines roles, responsibilities and a plan for care of trees in the public right of way.

The South Milwaukee City Council gave initial approval to the ordinance change at its meeting Tuesday night. Further discussion will be had at the committee and council levels before final passage.

The biggest fundamental change proposed: The city would assume control of “public trees,” including removing dead or dying trees and pruning other trees in the right of way.

The top priority is removing dead or dying trees — of all varieties, ash or not. That’s where the $300,000 comes in.  The money — part of a larger city bond issue for a wide variety of infrastructure projects the council gave final approval to on Tuesday — will be used to take down hundreds of public trees in poor shape across the city, including many suspected of suffering from EAB.

Those trees were identified as part of the recently completed tree survey, which you can see summarized here.

In the next eight to 10 years, you can expect to see all white, green and black ash trees in the city removed.

The three ordinance takes this a step further and starts us toward a necessary long-term strategy. Among the guiding principles behind this ordinance …

  • In the proposed ordinance, public trees are defined as those within the city right of way or on city-owned land (or in medians). For those with sidewalks, public trees are those between a sidewalk and curb. For those without, it’s a bit more complicated, where trees between the curb and property line planed as part of a development plan or city planting plan would be considered public. There will also be an appeal process where the city can deem trees as public if they sit in the right of way, are consistently spaced and within four feet of the curb and gutter.
  • As for maintenance, the city, in the proposed ordinance, is committing to “a systematic program to remove high-risk public trees,” as well as prune them. Trees will be removed or pruned based on condition, with the worst trees getting the highest priority. Some trees can be removed or pruned by city workers. Some will have to be contracted for removal or pruning, and that is where the $300,000 will come in. Either way, the city is agreeing to take responsibility for trees in its right of way vs. requiring homeowners to do it. This is significant.
  • The city would not fund treatment for trees infected with EAB, according to the proposed ordinance.
  • When it comes to replanting, the city would also not commit to doing so, although I am pushing hard to ensure we at least replant trees in the downtown area, on boulevards or on public parcels in the short term, hopefully with more down the road.

So, this is a start, and a necessary one.

We must do this from an insurance liability perspective. It’s also the right thing to do, and what’s best for the city. Communities have a responsibility to care for their urban canopy and ensure it thrives long term. Our urban forest is part of who we are as South Milwaukee, and it takes a village to maintain and enhance it – not blindly delegating this to individual property owners.

That said, I hope this work is just a sapling as we enhance our focus on urban forestry. We still have some big questions to answer, especially around ensuring we have the city manpower we need to manage a successful forestry program for the long term and properly execute the removal, pruning and replanting of trees. I also want to see us make a stronger commitment to replanting, hopefully where there comes a day soon when the city replants a tree for each one it takes down. Funding will be a signifcant issue here.

My pledge as mayor: To overcommunicate this. I realize the first question for many people will be, “What does this mean for me? What about my tree?” We will do our best to answer that question, sharing information through a variety of means (newsletter, websites, public meeting, etc.) and give opportunities for feedback. This starts with the next couple of weeks, before we pass the final ordinance. My door is always open too.

So stay tuned. Lines of communication will remain open as we evolve our work on urban forestry. For now, this is a good start, progress toward shedding our “Wild West” image.

A Path Forward On EAB And Urban Forestry

Urban forestry and a potential plan to combat emerald ash borer are on the agenda for Tuesday’s South Milwaukee City Council meeting.

It starts with a presentation by representatives from Bluestem Forestry Consulting Inc., which has completed its South Milwaukee tree inventory and its detailed look at the health of our ash trees.

The presentation starts at 6 p.m., followed by the actual council meeting.

The urban forestry management plan to be discussed can be found here. The EAB readiness plan can be found here. They contain some interesting, and sobering, data. From the inventory document …

  • A total of 4,491 trees, 97 stumps and 1,473 planting sites were inventoried (as part of the inventory of trees in the right of way and other “city-owned” trees).
  • 745 trees (16.61%) are green, black or white ash and are susceptible to Emerald Ash Borer.
  • 24.3% of all sites suitable for a tree are vacant. If no ash are chemically treated for preservation, another 16.6% of sites will be vacant. This would result in an extremely high tree vacancy rate.
  • Presently, the city does not provide any tree maintenance for street trees and homeowners are expected to provide all care. The city does care for park trees. The city should implement an urban forestry program for risk management purposes.
  • There are 336 recommended for removal for safety reasons . This is 5.5% of total inventoried population. A typical first-time inventory averages removals between 3-10%.
  • 235 trees should be pruned for safety reasons (3.9% of total inventoried population). A typical inventory averages 3-7% safety prune. This is a modest removal and safety prune rate for a first time inventory and indicates maintenance has been fair to good.

So, what to do about this? The EAB report takes a closer look at several options when it comes to tree maintenance …

  • Continue existing policy requiring homeowners to complete street tree maintenance;
  • Fully fund a municipal forestry program;
  • Partially fund street tree activities via a flat ‘subsidy’ per tree-related activity (fixed fee to abutting property owner);
  • Cost share with homeowners (percentage fee to abutting property owner); and a
  • Forestry fee (annual forestry fee per property)

There is lots of information and data in these reports that needs further examination. Whatever we decide, I’m glad we’re having this discussion. It needs to happen.

I believe the city has a responsibility to address this issue head-on and preserve (and enhance) our urban forest. It’s a worthy investment behind a community resource, our trees, that we probably take for granted.

Unfortunately, we’re in more of a reactive mode with EAB, like many communities. But we still have options. I look forward to discussing those — and figuring out a path forward through this forest.

It’s Official: EAB Is In South Milwaukee

That’s according to the Wisconsin Department of Agriculture, Trade and Consumer Protection, which has added South Milwaukee to its list of communities with confirmed cases of emerald ash borer.

Thankfully, we’re doing something about it, although I fear it’s too late. Our tree study is underway, and we’ll have a better idea of the potential scope of the problem — and potential short, medium and long-term solutions to debate — once it’s done.

Learn more about EAB here.

For the record, here are all the communities added today to the list of confirmed cases …

  • Village of Sharon, Walworth County
  • CIty of Delavan, Walworth County
  • Town of Bradford, Rock County
  • Town of Farmington, Washington County
  • City of South Milwaukee, Milwaukee County

Apparently, the infected tree in question in South Milwaukee was removed from Oak Creek Parkway.
