Scottsdale's Rules For Native Plants

Imagine buying a beautiful home in North Scottsdale. You've got mountain views, natural desert landscaping, and several mature trees surrounding the property. Lovely. But what happens if you want to remove a large palo verde to expand the patio? Or relocate a saguaro that's standing exactly where you'd like to build a guest house?

Well, here's where things get interesting. Owning the land doesn't automatically mean you can remove every plant growing on it. Scottsdale has its own native plant protections, Arizona has separate requirements, and certain properties contain protected desert areas with even stricter limitations. Let's sort out what homeowners can actually do.

Quick Points

• Scottsdale protects certain native trees and cacti.
• The city's Native Plant Ordinance applies citywide.
• NAOS areas have additional restrictions.
• Some projects require plant inventories and permits.
• Arizona has separate rules for protected species.
• Dead or hazardous plants require special consideration.
• HOA requirements may add another layer.

Not Every Native Plant Is Treated The Same

First, there's an important distinction between a plant being native to Arizona and a plant being legally protected under a particular ordinance.

Scottsdale's Native Plant Ordinance is found in Chapter 46, Article V of the City Code. It applies throughout Scottsdale, including established residential properties and areas with conventional landscaping.

The ordinance identifies certain native trees and cacti for protection.

According to the City's published list, the protection thresholds generally include:

• Listed cacti measuring three feet or taller.
• Listed trees measuring at least four inches in trunk caliper.

But the species must also appear on the applicable protected list.

That last detail matters.

A small ornamental plant in a landscaped courtyard isn't necessarily subject to the same requirements as a mature ironwood tree growing on an undeveloped desert lot.

And even a plant that doesn't meet Scottsdale's listed size threshold could be subject to another restriction, especially within dedicated Natural Area Open Space.

The species, size, location, and property documents all matter.

That's why homeowners should identify what they're dealing with before removing an established desert plant.

Which Native Plants Are Protected?

Scottsdale maintains an official Protected Native Plants list. It includes several species familiar to anyone spending time around the Sonoran Desert.

Among them:

• Saguaro: One of Arizona's most recognizable cacti.
• Barrel cactus: Included among the protected species.
• Blue palo verde: A familiar desert shade tree.
• Foothill palo verde: Common throughout desert environments.
• Ironwood: A native tree valued for its longevity.
• Mesquite: Multiple species appear on the City's list.
• Desert willow: Also included among protected trees.
• Ocotillo: Specifically identified on the protected list.
• Soaptree yucca: Another listed desert species.

This isn't the complete inventory. Scottsdale also identifies several other protected trees and plants.

And here's something homeowners sometimes overlook.

A mature native tree may have taken decades to reach its present size. Removing it could eliminate an established landscape feature that's difficult to replace.

That doesn't mean every protected plant must remain in its original position forever.

It means the proposed work needs to comply with the applicable rules.

Can You Move A Plant For Home Improvements?

Potentially. But Scottsdale's process is more involved than simply hiring a landscaping crew.

The City's native plant requirements emphasize preserving protected plants where practical. When development affects them, relocation and salvage may be considered.

For qualifying projects, Scottsdale requires documentation identifying protected plants and explaining what will happen to each one.

That can include:

• Which plants will remain in place.
• Which plants are proposed for relocation.
• Where salvaged plants will be replanted.
• Which plants cannot reasonably be preserved.
• How the work relates to the approved site plan.

Single-family construction projects generally require a native plant inventory and site plan as part of building-plan review.

There's another important detail.

Scottsdale states that native plant permits are issued in connection with approved or proposed development projects, following approval of the required native plant documentation.

So, if someone simply wants to remove a protected cactus from an existing yard without undertaking a development project, they shouldn't assume a stand-alone removal permit is automatically available.

The appropriate process needs to be determined with the City.

For a proposed addition, expanded driveway, or redesigned outdoor living area, identifying protected plants early can help avoid redesigns and unexpected expenses.

NAOS Changes The Rules

Now we get to one of the biggest distinctions affecting certain North Scottsdale properties.

NAOS stands for Natural Area Open Space.

Under Scottsdale's Environmentally Sensitive Lands Overlay, portions of certain properties must remain preserved as natural desert.

These requirements primarily affect designated desert and mountain areas north and east of the Central Arizona Project canal.

A homeowner can own land containing an NAOS easement. However, that protected portion of the property cannot be treated like an ordinary backyard.

Scottsdale's ESL and NAOS guidance restricts activities such as grading, clearing, landscaping, excavation, and vegetation removal.

And here's where the distinction becomes particularly important.

Native vegetation within dedicated NAOS generally must remain undisturbed, even when it doesn't meet the separate Native Plant Ordinance's species-and-size thresholds.

The City's guidance also addresses dead vegetation. A fallen saguaro, for example, can provide wildlife habitat and generally isn't something an owner should automatically remove.

Limited activities may be allowed, including certain invasive plant removal, approved maintenance, and fire-defensible-space work.

But NAOS isn't supposed to look like a freshly manicured residential landscape.

A homeowner wanting to trim vegetation, remove a tree, or clean out a protected desert area should first establish the applicable maintenance rules and any required approvals.

What Does Arizona Law Require?

Scottsdale's ordinance isn't the only set of rules involved.

Arizona has its own native plant laws administered through the Arizona Department of Agriculture.

These state requirements address matters such as clearing protected plants, relocation, transportation, salvage, and documentation.

Under Arizona Revised Statutes § 3-904, certain private land-clearing activities require advance notice to the Department of Agriculture.

The general notice periods are:

• 20 days: Affected areas smaller than one acre.
• 30 days: Affected areas from one to under 40 acres.
• 60 days: Affected areas of 40 acres or more.

But there's a significant exception.

The same statute excludes destruction of protected native plants on individually owned residential property of 10 acres or less where initial construction has already occurred.

That exception is especially relevant to owners of existing homes. It means the state's land-clearing notification requirements aren't identical for a developed residential parcel and a larger undeveloped property.

However, it doesn't cancel Scottsdale's municipal protections or an existing NAOS easement.

State rules also address relocating plants. Under A.R.S. § 3-906, moving a saguaro taller than four feet from its original growing location generally involves additional permit, tag, and seal requirements, subject to specific statutory exceptions.

So, before moving a protected plant off-site or arranging a major relocation, the applicable state requirements deserve separate attention.

What About Dead Or Dangerous Plants?

Here's a situation that deserves its own discussion.

Suppose a large cactus appears to be deteriorating. Or a mature tree develops a serious lean near the home's outdoor living area.

What happens then?

Scottsdale recognizes that native vegetation can sometimes become a property maintenance or safety concern.

The City's planning and permitting resources direct residents to ScottsdaleEZ for issues involving native plants in declining condition or at risk of falling.

But a declining plant isn't automatically exempt from every protection requirement.

For example, plants within dedicated NAOS may still be protected even after they die. Safety-related circumstances and applicable City approvals matter.

Outside NAOS, the process can differ depending on the plant, property, and proposed work.

A qualified arborist or cactus specialist can help assess the condition of a large plant and determine whether maintenance, stabilization, or removal deserves consideration.

That's particularly valuable when dealing with mature trees or heavy cacti near buildings and outdoor improvements.

And don't overlook pruning.

Routine trimming of vegetation in an ordinary landscaped area is a different activity from removing a protected plant. Substantial pruning within NAOS, however, can require City review.

The location changes the conversation.

Building A Custom Scottsdale Home

Now imagine purchasing vacant desert land with plans for a substantial custom residence.

You might envision a motor court, detached garage, guest house, outdoor entertaining areas, and an expansive pool.

But the property already contains established desert vegetation.

Some of those plants may be protected. Other areas could be subject to NAOS or approved disturbance limits.

This is why a native plant inventory can become part of the construction planning process.

An architect and landscape professional may need to consider:

• Existing protected trees and cacti.
• Approved areas for land disturbance.
• Potential salvage and relocation locations.
• Access for construction equipment.
• Drainage and natural washes.
• The intended building footprint.
• Space for future outdoor improvements.

Sometimes a modest adjustment to the site design can preserve an established tree.

Other times, relocation may be possible through the approved process.

And occasionally, the constraints can materially affect the intended project.

For buyers considering land in Arizona, this is another reason to investigate site conditions before committing to an expensive custom-home plan.

Beautiful desert acreage isn't necessarily land that can be cleared without restriction.

Before Hiring A Landscaping Crew

Here's a practical way to approach the situation.

Before scheduling work involving a mature native tree or cactus, establish what you're allowed to do.

A reasonable starting checklist includes:

• Identify the plant. Confirm its species and approximate size.
• Check the location. Determine whether it sits within NAOS.
• Review the site plan. Look for approved development restrictions.
• Check recorded documents. Confirm applicable easements.
• Contact Scottsdale. Establish whether approval is needed.
• Review state requirements. Especially before plant relocation.
• Check HOA rules. Architectural guidelines may impose additional limits.
• Use appropriate specialists. Large cactus relocation requires experience.

Scottsdale's Planning and Development Services Department can be reached at 480-312-2500 for questions about the applicable City process.

This is particularly worthwhile when a landscape contractor proposes removing a mature plant as part of a larger project.

A contractor's willingness to perform the work doesn't establish that the removal has been authorized.

Better to understand the requirements before the equipment arrives.

What Scottsdale Buyers Should Remember

Native desert vegetation is part of what makes many Scottsdale properties distinctive.

Established trees, natural rocky terrain, and protected open space can contribute to a property's setting. But they can also influence how much of the land can be modified.

For people evaluating Scottsdale real estate, it's worth looking beyond the landscaping itself.

Ask whether the property contains protected plants. Review any NAOS easements. Consider the location of future improvements and whether existing vegetation creates additional design or approval requirements.

And remember that a mature plant inside a landscaped courtyard may be governed differently from vegetation growing in dedicated natural open space.

The answer to whether you can remove native plants from Scottsdale property is sometimes yes, but it depends on the particular plant and the land beneath it.

For an owner planning a thoughtful landscape renovation, preservation or approved relocation may be practical. For someone considering a custom build, the existing desert could influence the design from day one.

Scottsdale's approach reflects an important balance. Property owners can pursue improvements, while the City maintains protections for natural desert features that often take generations to develop.

Understanding that balance makes it easier to plan a project that works with the property rather than running into preventable problems after construction planning has begun.
