Scorpion Valley Overview

On March 27, 2015, I evaluated the Monterey Cypress trees in the area of the

Kiosk, Scorpion Ranch, and the road up to NPS housing. I also evaluated the

Sydney Blue Gum Eucalyptus ("Eucalyptus") trees in the lower and upper campgrounds and the along with the roads that lead up to the lower and upper campgrounds.

Nicole Pino, of Treeco, Inc., was present during this site inspection and assisted with the recording of data collected during my tree observations. She also assisted in preparing this report.

For an overview of the trees in Scorpion Valley, see Appendix I.

All the trees that require work in order to help reduce branch failures are specifically listed in the Scorpion Valley Tree Evaluation Charts beginning on page 6. Photos for these trees listed in the Tree Evaluations Charts can be previewed in Appendix II.

Most of the trees in Scorpion Valley have been numbered for identification purposes with numbered aluminum metal tags installed on the individual trees.

Any trees that did not have the aluminum tags were marked with a black permanent marker for the purpose of this report.

Please refer to the Tree Map in Appendix IV for the tree locations in Scorpion

Valley.

In general most of the Monterey Cypress trees appear to be in good condition with the exception of a few trees that have some broken, hanging, branches which were broken by strong winds. (See Appendix II-Photos 4, 5, 6, 7, 8, 9, 10, 11, 15 & 16.)

One of the Monterey Cypress trees (Tree #530) is growing adjacent to the storage area and road going up to NPS housing. This tree appears to be infected with

Cypress Canker Disease. (See Photo 16.)

Tree # 530 should be the last Monterey Cypress tree to be pruned so that the

Cypress Canker Disease is not spread on pruning tools to the other Monterey

Cypress trees.

The last Monterey Cypress tree (Tree # 532) on the roadway up to NPS Housing

(overhanging the storage shed) has two (2) low heavy branches that should be pruned off. This tree has a very heavy, dense canopy leaning over the storage area. Its entire canopy should be selectively pruned to lighten up.

(See Photo 17 & 18.)

The Eucalyptus trees growing adjacent to the road leading up to the campgrounds and within the campgrounds appear to be in good condition. Although the Island has had below normal rainfall the past few years, the Eucalyptus trees have healthy leaf color, but have not produced a high amount of new foliage or much excessive weight except for a few individual trees.

The large Eucalyptus tree (Tree # 601), known as the “Tunnel Tree”, overhangs the beginning of the road leading into the lower campground was pruned last year. It presently appears to be relatively light. No pruning is required this year.

The lower southwest part of Tree # 601's canopy appears to be relatively thin due to an infestation of Eucalyptus Tortoise Beetles Trachymela sloanei. These beetles chew the edges of the leaves, but typically do not jeopardize the health of the tree.

This particularly thin section of the trees canopy does not need to be pruned at this time. (See Photos 19-21.)

I did not observe any trees that need to be removed at the present time.

Please refer to the Tree Evaluation Charts and photographs for recommended pruning.

I have included the International Society of Arboriculture Pruning Guidelines, intended as a guide for the contractor to follow while performing the work.

Please refer to Appendix III – ISA Pruning Guide Lines.

I recommend a Certified Arborist or Consulting Arborist be on site at all times to supervise the pruning in accordance with the ISA guidelines.

Appendix III

ISA Pruning Guidelines

ISA Pruning Guidelines

To be followed by contracted pruners

1) No more than 25% of live green foliage should be selectively removed from a branch or the entire tree unless recommended.

2) When a branch is cut back to a lateral, the remaining lateral branch must be at least one-third – one-half the diameter of the removed portion;

a.) Lion tailing is a poor pruning practice and it is not acceptable.

This practice is when an excessive number of branches that are thinned from the inside and lower part of specific limbs or a tree crown, leaving mostly terminal foliage. This results in poor branch taper, poor wind load distribution, and higher risk of branch failure. (BMP. Tree Pruning Revised 2008)

3) All broken and cracked branches found in the canopy must be removed.

4) All dead branches two inches or greater in diameter must be removed.

5) If the qualified Tree Pruner observes a potential for failure in the canopy of the tree while they are working in, they are expected to use their experience to relieve weight on the problem branch to help prevent failure or remove the entire branch (if needed) back to its attachment or a suitable size lateral branch.

6) Monterey Cypress tree(s): When removing the lower branches on that may be supporting a branch above, caution must be taken to prevent the supported upper branch form failure, because the lower supporting branch was removed. If needed, cut back the lower branch to where it is left in order to support the branch above it. This is a common problem when inexperienced tree workers attempt to prune Monterey Cypress trees.
