The following list of trees should not be planted in Southern California due to widespread lethal tree diseases that have no effective treatment. The pests\/diseases that are of greatest concern are Bacterial Leaf Scorch<\/em><\/strong> and Invasive Shot Hole Bore<\/em><\/strong>.<\/p>\n [\/et_pb_text][\/et_pb_column][\/et_pb_row][et_pb_row column_structure=”2_5,3_5″ admin_label=”row” _builder_version=”4.16″ background_size=”initial” background_position=”top_left” background_repeat=”repeat” global_colors_info=”{}”][et_pb_column type=”2_5″ _builder_version=”4.16″ custom_padding=”|||” global_colors_info=”{}” custom_padding__hover=”|||”][et_pb_text _builder_version=”4.16″ _module_preset=”default” global_colors_info=”{}”]<\/p>\n Bacterial Leaf Scorch has been present in California for more than 100 years. In 1990 Oleanders started dying and were diagnosed as infected with Xylella fastidiosa in 1993. Soon thereafter Liquidambar styraciflua, Plums, Crape Myrtle and Olive were observed dying and diagnosed as infected with Xylella fastidiosa. Xylella fastidiosa is the causal agent of Bacterial Leaf Scorch. These five hosts are now dying throughout Southern California. Any trees planted will likely die in 5-10 years and have no chance of reaching mature size before they die.<\/p>\n Trees NOT to plant due to Bacterial Leaf Scorch<\/p>\n [\/et_pb_text][\/et_pb_column][et_pb_column type=”3_5″ _builder_version=”4.16″ custom_padding=”|||” global_colors_info=”{}” custom_padding__hover=”|||”][et_pb_text _builder_version=”4.16″ _module_preset=”default” global_colors_info=”{}”]<\/p>\n Invasive Shot Hole Borer (ISHB) was first found at Whittier Narrows in Los Angeles County in 2003 but was not identified until several years later.<\/p>\n From 2003-2010 the beetle was found on a few ornamental trees, then in 2010 it was the presumptive cause of the death of a large number of box elder street trees in Long Beach. In 2012 the beetle was collected from a backyard avocado tree in South Gate, and from several tree species at local botanical gardens. It now appears to be established in Los Angeles, Orange, and Riverside Counties\u00a0and has also spread to selected areas of San Bernardino, Ventura and Santa Barbara Counties. A single beetle was caught in Santa Cruz\u00a0County in 2014.\u00a0<\/p>\n The host list for ISHB is now over 60 different tree species. Some hosts are preferred hosts and others are less attractive to the beetle. Preferred hosts of ISHB should not be planted as they will likely die in 5-10 years and never reach mature size before dying. I have observed that all species of Acer (Maple) and Platanus racemosa (Western Sycamore) are highly susceptible and are dying throughout Southern California and should not be planted.<\/p>\n [\/et_pb_text][et_pb_toggle title=”Trees NOT to Plants Due to Likely Death From ISHB” icon_color=”#e09900″ open_icon_color=”#e09900″ _builder_version=”4.16″ _module_preset=”default” title_text_color=”#000000″ title_font_size=”20px” border_width_all=”0px” global_colors_info=”{}”]<\/p>\n [\/et_pb_toggle][\/et_pb_column][\/et_pb_row][et_pb_row _builder_version=”4.16″ _module_preset=”default” global_colors_info=”{}”][et_pb_column type=”4_4″ _builder_version=”4.16″ _module_preset=”default” global_colors_info=”{}”][et_pb_text _builder_version=”4.16″ _module_preset=”default” global_colors_info=”{}”]<\/p>\n Consultant in Plant Pathology and Arboriculture [\/et_pb_text][\/et_pb_column][\/et_pb_row][\/et_pb_section][et_pb_section fb_built=”1″ _builder_version=”4.16″ _module_preset=”default” background_color=”#e09900″ global_colors_info=”{}”][et_pb_row _builder_version=”4.16″ _module_preset=”default” custom_padding=”0px||0px||false|false” global_colors_info=”{}”][et_pb_column type=”4_4″ _builder_version=”4.16″ _module_preset=”default” global_colors_info=”{}”][et_pb_button button_url=”https:\/\/altadenaheritage.org\/choose-your-tree-species\/” button_text=”Learn about Tree Species” button_alignment=”center” _builder_version=”4.18.0″ _module_preset=”default” custom_button=”on” button_text_color=”#ffffff” button_bg_color=”#e09900″ button_border_width=”0px” button_border_color=”RGBA(0,0,0,0)” button_font=”|700|||||||” custom_padding=”|66px||66px|false|false” global_colors_info=”{}”][\/et_pb_button][\/et_pb_column][\/et_pb_row][\/et_pb_section][et_pb_section fb_built=”1″ module_id=”resources” _builder_version=”4.16″ _module_preset=”default” global_colors_info=”{}”][et_pb_row column_structure=”1_5,3_5,1_5″ _builder_version=”4.16″ background_size=”initial” background_position=”top_left” background_repeat=”repeat” width=”91%” max_width=”964px” global_colors_info=”{}”][et_pb_column type=”1_5″ _builder_version=”4.16″ custom_padding=”|||” global_colors_info=”{}” custom_padding__hover=”|||”][et_pb_image src=”https:\/\/altadenaheritage.org\/wp-content\/uploads\/2021\/10\/Pink-Trumpet.jpg” title_text=”Pink Trumpet” _builder_version=”4.16″ _module_preset=”default” border_radii=”on|11px|11px|11px|11px” global_colors_info=”{}”][\/et_pb_image][\/et_pb_column][et_pb_column type=”3_5″ _builder_version=”4.16″ custom_padding=”|||” global_colors_info=”{}” custom_padding__hover=”|||”][et_pb_text _builder_version=”4.16″ _module_preset=”default” header_font_size=”39px” text_orientation=”center” width=”85%” width_tablet=”” width_phone=”88%” width_last_edited=”on|phone” module_alignment=”center” global_colors_info=”{}”]<\/p>\n Altadena Heritage has compiled the following list of online resources to learn more about trees – how to access, select, plant and care for them.<\/p>\n [\/et_pb_text][\/et_pb_column][et_pb_column type=”1_5″ _builder_version=”4.16″ custom_padding=”|||” global_colors_info=”{}” custom_padding__hover=”|||”][et_pb_image src=”https:\/\/altadenaheritage.org\/wp-content\/uploads\/2021\/10\/Gold-Medallion.jpg” title_text=”Gold Medallion” _builder_version=”4.16″ _module_preset=”default” border_radii=”on|11px|11px|11px|11px” global_colors_info=”{}”][\/et_pb_image][\/et_pb_column][\/et_pb_row][et_pb_row column_structure=”2_3,1_3″ _builder_version=”4.16″ _module_preset=”default” global_colors_info=”{}”][et_pb_column type=”2_3″ _builder_version=”4.16″ _module_preset=”default” global_colors_info=”{}”][et_pb_text _builder_version=”4.16″ _module_preset=”default” global_colors_info=”{}”]<\/p>\n [\/et_pb_text][et_pb_text _builder_version=”4.18.0″ _module_preset=”default” background_color=”#f2f2f2″ custom_padding=”33px|33px|33px|33px|false|false” custom_padding_tablet=”” custom_padding_phone=”22px|22px|22px|22px|false|false” custom_padding_last_edited=”on|phone” border_radii=”on|11px|11px|11px|11px” global_colors_info=”{}”]<\/p>\n L.A.

General Information<\/h1>\n
Provides a wealth of information on any particular species of tree.<\/p>\n
Very active in Los Angeles. This is a great website with lots of information about the Urban Forest, trees, gardening, how to get involved, etc. The DIY section is very good.<\/p>\n
Provides grants to communities for arbor day events and for large planting projects. They advocate for planting large trees, as those will have a larger impact on climate change and the urban heat island effect. Website has webinars, videos, slide show presentations, newsletter, links to many resources.<\/p>\n
Presentations of past seminars available here. Publishes a tree guide.<\/p>\n
Lots of advice for the tree owner, including how to buy a high-quality tree. Will help you find certified arborists in our area and check their credentials.<\/p>\n
Research-based advice on tree buying, planting, and care for the professional and the homeowner. See especially this guide: PDF<\/a><\/p>\n
Best management practices to protect birds and other wildlife during and beyond nesting season. Good resources page and some great photos.<\/p>\nSelecting the Right Tree<\/h1>\n
