Planting rare trees at Torrey Pines State Reserve.

An important reforestation effort is underway at Torrey Pines State Natural Reserve.

In recent years the critically endangered Torrey pine population has been reduced significantly by bark beetles, particularly in the park’s North Grove. So over 450 Torrey pine seedlings and 581 native shrubs grown in the nursery at the San Diego Safari Park are being planted in different locations around the Reserve.

You can read more about the project, an effort of California State Parks, the San Diego Zoo Wildlife Alliance, and the U.S. Forest Service, by clicking here.

I walked the loop of the Guy Fleming Trail yesterday, where visitors can see many of the dead Torrey pines. Among dead trees, clustered close to the ground, stand strange blue tubes. These plastic protectors shield growing trees and other plants from animals and drying winds.

Native shrubs that have also been planted, mostly above the west-facing bluffs facing the Pacific Ocean, include sea dahlia, jojoba, lanceleaf liveforever, fingertips (San Diego dudleya), lemonade berry, coast lilac, and San Diego mountain mahogany.

As I walked along, observing all those blue tubes, I paused to read signs that explain how bark beetles kill the rare and beautiful Torrey pine. This tree’s natural protection against beetle infestation is sap. During drought trees produce less sap than usual and become especially vulnerable.

Without sufficient water, trees cannot produce enough oleoresin, an oozy sap-substance, and one type of chemical defense that can flush beetles from trees…

Bark Beetle Trapping and Observation in Progress.

The Five-Spined Engraver Beetle is a native insect that survives by burrowing in the Torrey pine tree. During normal conditions, the pines will excrete sap to prevent beetles from laying eggs within the tree. The sap simultaneously protects the damaged bark from fungus and disease…

…The stacked black funnels that are seen on a dead Torrey pine contain a specialized chemical pheromone to attract and trap beetles…

Hundreds of new trees planted in Balboa Park.

I was walking through Balboa Park on Sunday, making my way toward Park Boulevard, when I noticed a newly planted tree with a shiny plaque beside it.

I veered across the grass to investigate…

The plaque states:

TREE BALBOA PARK

This tree and hundreds of others have been planted throughout the park by the Balboa Park Conservancy, Urban Corps, Tree San Diego, and Parks & Recreation.

Funding for this California Climate Investments grant project has been provided through the California Department of Forestry and Fire Protection (CAL FIRE), Urban and Community Forestry program.

Art exhibit: water, drought, and San Diego’s rainmaker.

The 9th floor gallery at San Diego's Central Library features an art exhibit called RAINMAKER. The theme is water, drought and climate change.

RAINMAKER is a fascinating, thought-provoking art exhibition at downtown San Diego’s Central Library. Because it will be coming to a close this weekend, I recently headed to the library’s 9th floor gallery to check it out.

Charles Hatfield was hired by the city of San Diego a hundred years ago to produce much-needed precipitation in order to fill Lake Morena. He might or might not have created the torrential rains and catastrophic flooding that followed his efforts at “moisture acceleration”. Was Hatfield an actual scientist or a charlatan? The question remains open.

This art exhibition focuses on the importance of water in our arid region, and how people affect and are influenced by the environment. Twelve local artists have contributed pieces which touch upon this theme. RAINMAKER is especially relevant today, considering San Diego’s current long drought, and the threat of coming winter storms caused by a strong El Niño that has developed in the Pacific Ocean.

Charles Hatfield, self-proclaimed rainmaker, was hired by the city of San Diego in 1915 to fill Lake Morena Reservoir during a severe drought. Record rain and floods ensued. Was this a coincidence?
