According to the Code, the City has the exclusive authority to plant, remove, prune, inspect, maintain, root prune or otherwise alter rights-of-way trees. A total of 157 trees were inventoried on and adjacent to the subject property. Of the 157 trees, 37 are considered rights-of-way trees and the remaining 120 are private property trees that are not “protected” by the City Code. Off-site trees on contiguous properties that may be affected by the construction of the proposed project are included in the inventory. BACKGROUND AND ASSIGNMENT The Compton Unified School District (CUSD) is proposing the reconstruction of the entire campus. The 157 inventoried trees are located throughout the property. We were retained to visit the property and inventory and photograph all private property trees and City rights-of-way regardless of size. A comprehensive analysis of each tree as it pertains to construction was not requested and is not a part of this study. This report is based on our site visit of February 27, 2018. OBSERVATIONS We inventoried 157 trees of various species. Tree trunks were recorded in the field, from grade, using Dulin & Boynton’s Topographic Map (August 10, 2000). The on-site trees were numbered and tagged with an embossed aluminum tag. Table 1 summarizes the inventoried trees and their protected status. Captioned photographs and exhibits at the end of this report illustrate site context, tree locations, tree structure, and vigor. A full-sized copy of the ‘Tree Location Exhibit’ is included in back pockets at the end of this report. CONCLUSION Once the design is finalized, CUSD may request an analysis of construction impacts to each tree and recommendations for protection of trees during the construction process. We are available to provide a proposal for this study as requested; this assignment was only for a site analysis.

(Rutaceae) are traditionally used in Africa, particularly in Cameroon, as a spice and in the treatment of sickle cell anaemia. The objective of this study was to investigate the fruit essential oils from different sample locations and during their maturation period by using GC and GC-MS. Except for one sample collected in Aniak which consisted mainly of oxygenated monoterpenes, the volatile composition of Z. leprieurii fruits exhibited relative high amounts of monoterpene hydrocarbons (61.190.9%) such as (E)βocimene (13.475.2%) and -pinene (1.140.7%).

  • Brazilian Pepper – Why It Is So Terrible!
    Brazilian Pepper – Why it is so terrible! Brazilian pepper (Schinus terebinthifolia) is a species of flowering plant in the cashew family, Anacardiaceae, that is native to subtropical and tropical South America (southeastern Brazil, northern Argentina, and Paraguay). The family Anacardiaceae also contains poison ivy, poison oak, and poison sumac. Like many other species in the family Anacardiaceae, Brazilian pepper has an aromatic sap that can cause skin reactions (similar to poison ivy burns) in some sensitive people. Some people have also expressed respiratory problems associated with the bloom period of the pepper tree. Brazilian pepper was brought into Florida in mid-1800s for use as an ornamental plant, before people were aware of the problems it would create. Its bright red berries and brilliant green foliage were used frequently as Christmas decoration as its berries ripen in late fall, and is sometimes known as “Florida holly”. Brazilian pepper in bloom Unripe fruit/berries and foliage Distribution of Brazilian pepper tree throughout Florida is widespread, although limited to the warmer areas due to sensitivity to cold temperatures. It is one of the most aggressive of the invasive non-indigenous exotic pest plants in the State of Florida. There are over 700,000 acres in Florida infested with Brazilian pepper tree. It can be found as far north as Levy and St. Johns Counties, and as far west as Santa Rosa County. Many plant communities such as hammocks, pinelands and mangrove forests are often invaded and dominated by the Brazilian pepper tree. Its growth habit allows it to climb over understory trees and invade mature canopies, forming thickets that choke out most other plants.

The experiment was performed by 78 days, under four irrigation intervals: 0, 4, 8, and 12 days, in combination with four concentrations SA: 0, 50, 100, and 200 mg L-1. The irrigation was individually maintaining water retention capacity of 100%, under each irrigation intervals. The maximum height across the irrigation intervals was 24.74 cm at 7-days intervals, and 24.31 cm with 200 mg L-1 of SA. The largest leaf areas were 116.03 cm2 at 12-day interval and 123.71 cm2 with 200 mg L-1 of SA. The highest production of dry masses of leaves, stem and roots was without and 12-days intervals, both with 200 mg L-1 of SA. Exogenous application of 200 mg L-1 of SA contributed on increased growth in S. terebinthifolia seedlings subjected to 12-days irrigation interval.

  • Site Meeting 7/29/14 (BMM)
    APP 698570 – I-75 North of Kings Hwy to S. of Toledo Blade Widening FIELD NOTES: Site Meeting 7/29/14 (BMM) 100L – FLUCCS 641 This system is located on the south side of I-75. This wetland historically extended to the north and connected to the wetland on the north side of I-75. Surrounding habitat is primarily pine flatwoods. During field surveys in April 2013 no standing water was observed. The dominant species within the assessment area are frog fruit (Phyla nodiflora) and arrowhead (Sagittaria lancifolia); subdominant vegetation includes dog fennel (Eupatorium capillifolium), carpet grass (Axonopus furcatus), Carolina willow (Salix caroliniana), Peruvian primrose willow (Ludwigia peruviana), and wax myrtle (Myrica cerifera). This wetland contains a low coverage of nuisance exotic species. 105M – FLUCCS 641 This system is located in the median of I-75. Historically, this wetland was a part of a larger system that continues to the north side of I-75; the current connection is through a culvert under the road. Surrounding habitat is primarily mowed median. During field surveys in April 2013 no standing water was observed. Dominant vegetation included Peruvian primrose willow and Carolina willow. Subdominant vegetation included broomsedge bluestem (Andropogon virginicus), arrowhead, grapevine (Vitis sp.), Brazilian pepper (Schinus terebinthifolia), frog fruit, dog fennel, mock bishops weed (Ptilimnium capillaceum), torpedo grass (Panicum repens), a few live oak (Quercus virginiana), and bahia grass (Paspalum notatum).

    SP 242 Integrated Management of Non-Native Plants in Natural Areas of Florida1 Stephen F. Enloe, Ken Langeland, Jason Ferrell, Brent Sellers, and Greg MacDonald2 Introduction Regardless of how they arrived, these 1,400+ non-native plants grew so well in Florida that they established and Florida’s natural areas encompass an incredible diversity reproduced on their own and spread into natural areas. of native plants and animals and provide a wide array of Out of these 1,400+ species, approximately 165 (11%) are ecosystem services that benefit Florida greatly. Within the considered invasive and may disrupt ecosystem services state, there are almost ten million acres of local, state, and vital to the integrity of Florida natural areas (FLEPPC federal public lands currently managed as natural areas for 2017). Among these, approximately 100 species require conservation. While natural areas are conservation lands aggressive management. that have been set aside for the purpose of preserving (or restoring) native plant and animal communities, they do Management of invasive vegetation in natural areas require active management.
