Pontiac, MI Tree Protection: Protected Tree Species (2026)

Chapter 130, Woodlands Preservation Regulations, opens with findings that unregulated tree removal threatens erosion control, air-quality benefits, property values and neighborhood character (§ 130-1). Section 130-2 defines a protected tree by a six-inch d.b.h., measured with a diameter tape four and one-half feet above grade, and lists eleven exempt species by common and scientific name, Boxelder, Silver Maple, Poplars, Willows, Siberian Elm, Tree of Heaven, European White Birch, Catalpa, Common Honeylocust, Red Mulberry and White Mulberry, that never count as protected no matter their size.

Removing, cutting, transplanting or damaging any tree that does not fall on that exemption list triggers the permit requirement in § 130-3, reviewed by the Planning Administrator, the Community Development Department or the Planning Commission depending on whether a site plan or plat is involved. Large-tract developments must preserve at least 80 percent of protected trees under § 130-3(c)(5), and § 130-4 lists narrow exceptions for licensed tree farms, storm emergencies, utility work, forester-certified management plans, and small tracts already holding a single-family home. A denied applicant can seek a City Council public hearing on a practical-difficulty variance under § 130-14, with further appeal to the Oakland County Circuit Court. Every provision in the chapter traces to Ordinance No. 2115, adopted August 31, 2000.
