Oregon white oak tree health report – May of 2026

Oregon white oak tree health report for May of 2026.

Part of our agreement with Single Line Tree Care was not only to trim branches away from homes and roofs, but to evaluate the health of the trees in our community. Single Line Tree Care, along with the other four companies that provided bids, commented on the good health of the trees in the neighborhood.

The large Oregon white oaks in the southwest corner of the property were given extra attention by David D. Hunter, an ISA certified arborist and ISA qualified tree risk assessor, as Oregon white oaks are the same species of tree that fell in the southeast corner of the property in March.

Hunter found no reason to cutdown any of the Oregon white oaks, but fungus (which was dead, see image below) was found on the white oak closest to 3087’s door. We need help from the community to monitor the fungus. If it comes back, the tree may need to be cut down.

Dead fungus found on Oregon white oak

When you are walking in the neighborhood or working in your yard please take a look at the trees in the area and if an issue is seen, please send an e-mail to the board. Catching an issue early could save a tree and/or prevent property damage.

Below are some tips to identify issues with Oregon white oaks.

  • Fungal growth at the base
  • Canopy dying
  • Peeling bark

The following are the notes made by Mr. Hunter who assessed the Oregon white oaks in the southwest corner of the property on May 14, 2026.

Two white oaks near 3151
#1 – white oak, back right corner. Tree was tested and probed – no issues, but needs to be monitored for significant die off over the years.

#2 – white oak, back center of house. Tree was tested and probed – no issues, but needs to be monitored for significant die off over the years.


Three white oaks on the side of 3084
#1 – white oak by mailbox cluster. Tree was tested and probed – no issues, but needs to be monitored for significant die off over the years.

#2 – white oak, small one in the middle. Tree was tested and probed – no issues, but needs to be monitored for significant die off over the years.

#3 – white oak near guest parking location. Tree was tested and probed – no issues, but needs to be monitored for significant die off over the years.


Cluster of white oaks near 3087
Three stem white oak near front door – This tree is the most concerning. Found wood rotting fungus on the bottom, but was dead. Tree was probed, went in about a foot and found no indication of rotting. Needs to be monitored for fungus and significant die off over the years.

All of the other white oaks were checked in the surrounding area and had no concerns except for large dead for safety above walking trail and school parking lot. Trees are healthy.

In the fall, need to check the base of the trees for fungus or mushrooms. Wood chips need to be 3-4 feet off the trunks of the trees as they can promote fungus growth and can hold water which can lead to root rotting.
