Full Breakdown
Chapter 66 of the Monroe Township Code (Middlesex County) protects one named tree rather than setting up a townshipwide heritage program. Section 66-1 records that the Monroe Oak, which appears on the Official Seal of the Township, stands at Block 45, Lot 1, on the northerly corner of Applegarth and Prospect Plains Roads. A certified tree expert's September 1998 inspection found a white oak 65 feet tall, with an estimated age between 390 and 450 years, a trunk circumference of 17 feet, seven inches, and an average crown spread of 100 feet.
Section 66-2 states the purpose: to make the tree the common property of the citizens of the Township, to be protected and maintained by the Township. Section 66-3 supplies the designation itself. Removal is controlled by § 66-4, and the decision belongs to the Township Council. The Council can act only where the tree is so diseased or infested as to endanger the public or to be a danger to other trees, where it is dead and its continued presence would cause endangerment to the public, the property owner or an adjoining property owner, or where it is detrimental to health or safety.
Section 66-5 sets the day-to-day rules. No person can pave over the roots, scrape away topsoil to expose roots, or otherwise harm the tree within its drip line, defined as a line connecting the tips of the outermost branches projected vertically onto the ground. Anyone performing line clearance operations that require trimming or pruning must first obtain written approval from the Monroe Township Conservation Officer 30 days before the activity. Under § 66-6 the Township holds an unfettered right to enter the property at any time for the sole purpose of inspecting, maintaining and protecting the tree, in addition to the owner or the person in possession. The chapter names only the Monroe Oak and contains no procedure for nominating other trees.
Violations & Fines
Intentional harm or injury to the Monroe Oak is punishable on conviction by a fine of not less than $50,000, imprisonment for a term not to exceed one year, or both (§ 66-5D). Anyone who causes damage to the tree is held liable, and the Township has the right to cure the damage and bill the cost to the party responsible (§ 66-5C). Paving over roots, scraping topsoil, or pruning without the 30-day written approval of the Conservation Officer breaks § 66-5A or § 66-5B.
