Tree Protection

Report

Many cities have enacted tree protection ordinances in order to protect trees from the potential negative impacts from construction and to encourage responsible planning. Trees vary in their ability to adapt to altered growing conditions. Cities require an arborist report since mature trees have established stable biological systems.

Tree Appraisals

Report

Trees are valuable, both on their own and for their contribution to the overall property value. Hiring an experienced tree expert who specializes in tree appraisals can make the difference in the outcome of a claim. Our results speak for themselves.

Expert Witness

Report

Evergreen Arborist Consultants, Inc. provides comprehensive litigation, consulting, and expert witness testimony on tree and landscape issues.

Tree Roots

Report

Tree roots are arguably the most important part of a tree as the tree gains nutrients, oxygen, and water from its roots and healthy tree roots not only supply these health-giving components, but also supply strength and stability for the tree. When tree roots are unhealthy, tree and/or branch failure may occur.

Mike Green from Evergreen Arborist assessed the health of a large Redwood tree in my parents backyard. Mike was very friendly and easy to work with. Most importantly he is extremely knowledgeable in his field and provided the tips they needed to help improve the health of their tree. Highly recommend using Evergreen for any arborist needs you may have.

We were in litigation regarding the cutting down of a beautiful Jeffery Pine tree. We needed an expert to explain the life stage of the Jeffery Pine as well as a valuation of the Jeffery Pine. We happened upon Ruben Green. Mr. Green was invaluable in his report, explanation, and testimony. He was able to explain the situation in a way that we non-tree folk could understand, and when he testified at trial, he was very professional, succinct, and invaluable to proving our case. I would gladly use and recommend the services of Mr. Green.

I am an attorney and Realtor and handle many real estate cases. I hired Evergreen, Ruben, and his son to conduct an expert analysis of damage done to a valuable tree. Their work was top notch and exactly what I needed for my case. They were also very responsive to my calls and questions. I'd recommend them to anyone. Thanks!

Michael of Evergreen was great to work with. I've had about five other arborists and gardeners in and none of them came anywhere nearly as close to being as knowledgeable and thorough. Plus he was genuinely personable and easy to get along with. When I needed a bit of follow-up info by phone, he was Johnny-on-the-spot with added, free advice. Highly recommended.

It started to die after only 6 months with Michaels recommendations our tree looks beautiful only 3 months later. Being in a service industry I really appreciated the prompt appointment. I highly recommend Ruben and Michael they are both very knowledgeable.

I can't say enough good things about Michael Green and Evergreen Arborist Consultants. Michael was extremely knowledgable, but more than that he went the extra mile. Rather than just write the report we asked him to write, Michael took the initiative to eliminate the need for the report. That diligence saved us months on our project and made what could have been a drawn out, painful, bureaucratic process into a speedy, efficient pleasure.

And its worth noting, that in doing that I was billed half of the original quote for the job. I'm so appreciative of the great work and the kindness Michael showed and I would recommend him without reservation to anyone who needs an arborist.

Michael at Evergreen Arborist was extremely knowledgeable and well spoken in dealing with our avocado tree issues. He identified some key indictators of issues right away and gave us a detailed breakdown on how to mitigate further degradation in the tree. It's been 6mo and the tree is looking better than ever. We're hoping things continue to improve and one day bring back our avocado fruit. I would rercommend Evergreen to anyone residential or Commerical looking for a qualified arborist to assess your landscape/tree needs.
