Menlo Oaks Tree Advocacy Group

Several neighbors formed Menlo Oaks Tree Advocacy (MOTA) in 2014 to educate and work with residents, developers, and the County on behalf of the significant old-growth and heritage trees in Menlo Oaks. Working with MODA, this group welcomes your participation. Please contact MOTA or MODA with your ideas and suggestions.

Our Trees Are Living History

Menlo Oak residents are the beneficiaries of San Mateo County’s valuable oak savannah, and these natural sculptures have a prestigious and valuable history. They also provide many health advantages to each of us.

Just how old is that tree in your yard?  If you have an oak that’s 75″ in diameter, it is roughly 300 years old. 
No need to count the rings. There’s a safe way to get a general idea of the age of your natural asset, understanding that arborists have a more complicated formula and urban trees grow more slowly than forest trees because of stress.

4 Key Ways To Protect Your Native Oaks From Disease

1. Remove competing plants, including ivy and lawn

2. Remove built-up soil from around the root crown

3. Water properly
The area within 10 feet (or more) of the trunk of a native oak should remain undisturbed and clear of any vegetation and irrigation. Ideally no irrigation should be applied and no lawn installed in the area extending from the base of the trunk out to the tree’s drip line. It’s best to remove existing lawn inside the drip line; this will reduce competition from other plants and help eliminate excess moisture. Do not water or allow water to collect around the root flare. Do not allow sprinklers to spray on the trunk.

4. Have your tree evaluated for root crown infection by an ISA-certified arborist.

Working With The County

MOTA advocates with San Mateo County Planning & Building Department to improve and enforce the current regulations that prohibit destroying a heritage or significant tree unless it is diseased or a safety hazard. MOTA’s goal is to ensure that our trees receive the protection they need and deserve.

Our Trees As Assets

Our trees keep the neighborhood vibrant and property values high. They are part of our indigenous landscape and have grown in our neighborhood for many years – in some cases for three or four centuries. Significant old-growth and heritage trees are well established and face far fewer dangers from drought and provide many benefits to residents.
