Protecting our Friends, the Trees

 

Las Cruces City Council will consider a tree ordinance.

No, the trees haven’t been speeding, littering, or stealing hubcaps. They’re our best citizens, providing delightful oxygen and thwarting our enemies, those greenhouse gases and other pollutants. They help protect us. They’re not as good at protecting themselves from us.

Why do we need a tree ordinance, what would it do, and what should we do?

Taking the last first, show support by calling and writing your city councilor and urging others to do the same.

Trees work hard for us. Trees in Las Cruces annually remove 45 tons of ozone, sequester 17,800 tons of carbon, provide 3,290 tons of oxygen, and intercept rainwater. That interception helps our soils retain water, resulting in significantly less runoff, flooding, and erosion. For every 10% increase in a city’s tree canopy, the ambient heat declines 2 degrees Fahrenheit. As you’ve probably noticed, in the shade of a tree, a 100 degree day feels like 50-75 degrees. Trees are nice to look at, too! Planting a tree in your front yard can increase your property’s value 30%.

Urban trees even help reduce crime. A team of researchers studying the relationship between tree canopy and crime in and around Baltimore found that a 10% increase in trees roughly equaled a 12% decrease in crime.  A U.S. Forest Service study in the Pacific Northwest confirmed that neighborhoods with homes fronted with street trees experienced lower crime rates – and the results held for crimes generally, not just vandalism and burglary. (It may be that trees alert someone that a house is better cared-for by occupants particularly vigilant about protecting it.)

A tree ordinance would be a great first step to protect existing trees on public property. It deserves enthusiastic buy-in from citizens, councilors, and staff. A tree ordinance can protect, maintain, and increase our tree canopy, keeping both trees and us healthier. Las Cruces also needs to maintain its Community Forester position. Because the excellent Jimmy Zabriskie retires 31 December, urge the City to hire a fully qualified replacement ASAP. (I hope we’ve started already!)

Meanwhile, let’s plant more trees. Not just any trees, but trees that thrive here: trees that can survive our drought and blistering heat, and also the occasional hard freeze. (Such as mesquite and desert willows.)

Fortunately, tree planting is also in the works. Nonprofit Tree NM (“TREE”) has had some success with its NeighborWoods program. The model, Albuquerque NeighborWoods, is a collaboration among TREE, the City, state foresters, neighborhood leaders, and others to provide funding, training, and education for a neighborhood to plant 100 street trees and give 100 trees to homeowners. Each neighborhood provides at least five lead volunteers to help drive the project, and additional volunteers to plant the trees. (The collaboration means there’s no violation of the Anti-Donation Clause.)

TREE has received a grant to extend NeighborWoods to Las Cruces. We might hear before next fall about tree-planting here, maybe in your neighborhood. (You could even volunteer to help plant some.)

In a 28 November work session, the City Council directed legal staff to prepare an ordinance. (Councilor Yvonne Flores asked about the possibility of extending the ordinance to cover businesses and developments. Once the city’s lawyers hash out the legal language, Las Cruces could benefit from doing that too. Only 3% of our trees are on public land.)

Hugging trees is good. Protecting them by ordinance is vital.

A related radio commentary will air during the week on KRWG (90.7 FM) and on KTAL (101.5 FM / http://www.lccommunityradio.org/) and be available on both stations’ websites.]

[The ordinance has not even been drafted yet; but it’s one we need, and should encourage the City Council to move quickly on. I’ll also try to reach the TreeNM folks to get a better sense of when they may be working here, how one might suggest a particular neighborhood to them, the scale of what they’ll be doing here, etc.

I think the ordinance (or a second ordinance that quickly follows) should also cover businesses and developers. That may be more controversial, though it shouldn’t be.

But then, I think state law should prohibit anyone in or after 2023 from planting more than five pecan trees on any property. A crazy thought I’ve had for years. I’m finding that many people in more responsible positions feel the same way, it just ain’t politic to say so. But I ain’t runnin’ for nothin’, so.]

  1. Thanks for your LC Sun News opinion article I read first, and this post. On 12/1 the City posted the job to replace the retiring community forester:

    A City tree ordinance is a good idea for your stated reasons and many others. Though I question the basis for the stated shade "feels like 50-75 degrees" temperature on a 100F day or "increase your property’s value 30%" with a front yard tree. The latter depends much on locale or species.

    Other points for such a tree ordinance:
    1) add to or reference existing CLC landscape ordinances?
    2) real support & will of mayor, city council, dept. management?
    3) horticultural background and basis for that support?
    4) tree examples that work and don't, reasons?
    5) site and infrastructure requirements to grow trees
    6) tree root zone / soil volume accommodations
    7) irrigation mechanism, realities, and requirements
    8) maintenance mechanism, staffing, realities, and requirements
    9) passive water harvesting / green infrastructure tie-in
    10) selection - species available, minimum sizes and locations, irrigation
    11) public, private, new construction, exist. construction retrofit?
    12) opportunities - land area to plant? (CLC %, new development %, existing dev. %)
    13) constraints - private property owners' (sacred) views, nuisance concerns, etc.
    14) developer collaboration (a huge % of land area in CLC is private)
    15) preservation of sight lines for business signage

    I don't live in the city limits, but like many I shop, eat out, and have business in Las Cruces many days each week, so this interests me. Plus I was in landscape architecture for over 2 decades and a planner for over 3 years.

    Let me know if you want to discuss further.
