Invasive Shot Hole Borer Quarterly Situation Report

“Pick a tree at random anywhere in Southern California and examine it closely. Chances are good that you will find small wet stains on its
trunk. Those wet stains are most likely signs of a fatal tree disease that is spreading throughout the region at an alarming rate, and which
has the potential to significantly change the way Southern California looks.

The disease is called Fusarium dieback, and it is transmitted by one type of fungus-farming beetle: the invasive shot hole borer.

Thought to have arrived in Southern California in packing materials from Southeast Asia, this beetle burrows into trees and grows fungal pathogens
for food. The pathogens then interrupt the transport of water and nutrients within the tree from roots to leaves, eventually causing branch dieback
and possibly death.” – Akif Eskalen, Shannon Lunch.  LA Times 11/30/17

We have posted the quarterly situation report for Invasive Shot Hole Borers on our website.

Promoting trees this Arbor Day Season

Here are some great thoughts from Dana Karcher, with Alliance for Community Trees during this Arbor Day Season.

Every time Congress zeros out the Urban and Community Forestry budget, my phone rings with calls of despair. Usually I respond with this query: When was the last time you told the story of how trees are changing your community to your Congressional representative? When was the last time you put a shovel in their hand and had them join you in a planting?
Our tree planting stories begin at home, not on Capitol Hill. To maintain, or even grow our slice to the budget pie, we must place importance on the projects that make a difference in our towns and cities. We know what trees can do for communities; let’s not keep that secret from our legislators.
Here are a couple of ideas:
· Arbor Day is the perfect time for legislative members to take that perfect photo. Invite them to your celebration, alert the media, and share the benefits of trees with them.
· Start writing letters. (Or continue writing letters.) Keep them brief and focused on what trees do for their constituents. Engage your supporters to do the same thing.
· Share what your community would be like without trees.  Can you imagine? Neither can the Chamber of Commerce, the Convention and Visitors Bureau, and all of your community cheerleaders. Tell the story of no shade, increased incidences of asthma, heat-island effect, and more particulate matter.
Whatever you choose to do, don’t neglect the opportunity to assure that funding for Community Forestry is part of your daily message.  Lastly, be sure to share your successes with your fellow members. Write us a story! Click here to send us what has been working for you!

“Remember The Trees” an Art Exhibition by Ruth Waller through April 3rd

“Since 2010, over 100 million trees have died in California alone–ravaged by beetles, drought, fires and more. Humans and trees are bound in reciprocity. In addition to shade, shelter and food, trees produce oxygen and take up the carbon dioxide that we increasingly spew into the atmosphere. In many cultures, trees are a symbol of life itself. What does it mean that the trees are dying?

This exhibition chronicles the ecological changes in a few locations in southern California from Torrey Pines State Park, Mount Cuchama, Mount Laguna and Pine Creek Wilderness in San Diego County, to Joshua Tree, Walker Pass and Alta Sierra further north. Coastal chaparral, pines, oaks, Tecate cypress, and more are represented in sumptuous photomontages that express the dynamic qualities of these environments. As opposed to the grandiose sublime, these visuals encourage active exploration, offering glimpses, or incomplete views at a variety of scales evocative of the enchanted vibrancy of life.”
