These
provide a general list of the many aspects of salvage and transplanting which shall be addressed by a contractor. Current
and professional practices for the arid southwest should always be followed.
The basic plant protection and salvage philosophy is to preserve-in-place as much native vegetation as possible and to utilize salvaged vegetation for landscaping in those areas that are graded or otherwise disturbed.
A. Season of the year;
B. Feasibility of successful salvage/transplant;
C. Pruning requirements before and after transplant;
D. Appropriate box size for salvaged material based on trunk diameter;
E. Side boxing techniques and timing;
F. Plant removal techniques and transportation techniques;
G. Maintenance in temporary holding nursery;
H. Permanent location planting techniques; and,
I. Long-term maintenance.
A. Season of the year;
B. Orientation of the plant at the original site and in the holding nursery. All Saguaros and cacti should be stored and transplanted in the same north-south orientation as they naturally grow in the desert to avoid sunburn. All Saguaros and cacti should be premarked on the south side before moving. Any size Saguaro and cactus can be planted in full sun if it was originally growing in full sun; otherwise, provide artificial shade for a season, or plant under a tree or shrub. Cacti which were not in full sun must be protected by shade cloth or other shade in the nursery;
C. Excavation of adequate root system;
D. Protection of epidermis with burlap, foam rubber, or other padding;
E. Support of the plant during salvage and transport;
F. Final planting techniques;
G. Maintenance in temporary holding nursery; and,
H. Long-term maintenance.

EXHIBIT I: NATIVE PLANT PRESERVATION WORKSHEET
This worksheet outlines the steps needed to calculate numbers for meeting the minimum
, preservation credits, and mitigation requirements of the Native Plant Preservation Ordinance utilizing the Plant Inventory Methodology. This Worksheet has been designed to assist in calculating the numbers of plants needed for the Salvage and Mitigation Report described in Section 2-11.5.0; however, this particular Worksheet is not required as part of the submittal but the calculations are required. Fill out a separate worksheet for every genus and species of plant.
Abbreviations and Definitions used: | PIP = plants preserved-in-place |
TOS = plants transplanted on-site | |
RFS = plants removed from site, damaged, or destroyed | |
Mitigation = additional plants to be planted on-site |
NAME OF PLANT (GENUS AND SPECIES)
STEP ONE Minimum Requirements for PIP or TOS
1. Number of plants of this genus and species inventoried and rated viable:
(1)
2. Multiply line 1 by the appropriate number below.
When the result includes a fractional amount, .1 - .4 is rounded down to the next
lower whole number, and .5 - .9 is rounded up to the next higher whole number.
Saguaros and Ironwood trees .5 x =
Other Plants .3 x =
Enter the minimum number of PIP and/or TOS required here: (2)
3. Enter total number of plants proposed to be PIP: (3)
4. If line 3 is less than line 2, subtract line 3 from line 2 and enter here: (4)
If line 3 is more than or equal to line 2, enter 0.
This is the minimum number of plants required to be TOS.
5. Enter total number of plants proposed to be TOS: (5)
6. Subtract line 4 from line 5 and enter here: (6)
This is the number of “excess” plants to be TOS.
7. Add line 3 and line 5 and enter here: (7)
This is the total number of plants that will remain on the site.
8. Subtract line 7 from line 1 and enter here: (8)
This is the total number of plants proposed for RFS.
STEP TWO Preservation Credits for Plants PIP
9. Multiply the number of plants PIP, based on plant size, by the appropriate multiplier below and enter here. Add the total, for each plant, and enter the total preservation credits here. (9)
Saguaros 6-10' high | 2 x _______ = ________ |
Saguaros >10' high | 3 x _______ = ________ |
Ironwood trees 6-12" in caliper | 2 x _______ = ________ |
Ironwood trees >12" in caliper | 3 x _______ = ________ |
Barrel Cacti >2' high | 2 x _______ = ________ |
Other Cacti >4" high | 2 x _______ = ________ |
Ocotillos >6' high | 2 x _______ = ________ |
Yuccas >2' high | 2 x _______ = ________ |
Other Trees 6-14" in caliper | 2 x _______ = ________ |
Other Trees >14" in caliper | 4 x _______ = ________ |
Shrubs >6' in height or diameter | 2 x _______ = ________ |
STEP THREE Mitigation Requirements for Plants TOS and RFS
10. Enter number of plants from line 4 here: (10)
This is the mitigation requirement for the required number of plants TOS.
11. Multiply the number of plants from line 8 by the appropriate multiplier below and enter result here: (11)
This is the mitigation requirement for plants RFS.
Saguaros and Ironwood trees: | 3 x ________ = ________ |
Other plants: | 2 x ________ = ________ |
12. Add line 10 and line 11 and enter total here: (12)
This is the total number of plants required for mitigation.
STEP FOUR Net Mitigation Requirements
This step balances the preservation credits and requirements.
13. Subtract line 6 from line 12 and enter here: (13)
This is mitigation requirement reduced by “excess” plants TOS.
14. Subtract line 9 from line 13 and enter here: (14)
This is mitigation requirement reduced by preservation credits.
15. If amount on line 14 is greater than 0, enter number here:
(15)
If amount on line 14 is 0 or less, enter 0 here (no mitigation is required for this plant).
This is the number of mitigation plants that must be provided.
16. Add line 7 and line 15 and enter number here: (16)
This is the total number of plants (of this genus and species) that will be on the site.
