Hey fourth graders! Join Every Kid in a Park for FREE!!!

kid in a park

Although this program does not apply to Goodan Ranch, it does apply to ALL NATIONAL PARKS.   Every Kid in a Park is a fabulous program!

Together, we can inspire the nation’s next generation of cultural and environmental stewards by

instilling them with curiosity about natural wonders,
furthering their understanding of historic events, and
fostering their appreciation for diverse cultural heritage.

Every Kid in a Park is a movement designed to give every fourth grader the opportunity to experience the living classroom of America’s national parks and historic sites. Between the ages of 9 and 11, kids are most open to learning about the world around them; yet, so many spend more time sitting in front of a screen than exploring environments that foster deeper learning and fulfillment. And most American families live in cities, without access to safe outdoor play areas. Beginning in the 2015 school year, these young Americans are eligible for a pass granting them—and their families—FREE entry to more than 2,000 federally managed lands and waters.

Research shows that children ages 9 to 11 are in the midst of a particularly unique developmental stage. During which, they form a more concrete understanding of how the world works, they are more receptive to new ideas, and they are most likely to have positive attitudes about nature and the environment. By focusing efforts specifically on fourth graders, the initiative aims to ensure kids have the opportunity to visit and enjoy federal lands and waters during this developmental stage.

At sites that charge per vehicle, the Every Kid in a Park pass admits the fourth grade pass owner and the accompanying passengers in a private, non-commercial vehicle. At sites that charge per person, the pass admits the pass owner and up to three accompanying adults (entering by foot or bike). Please note that fourth graders must be present at entry.

Fourth graders can obtain a paper pass for free entry into all federal lands and waters by visiting www.everykidinapark.gov. Fourth graders can then exchange the paper pass for a durable plastic pass at select participating sites.  Then Voila!  You are a member of Every Kid in a Park.

Educators can also visit www.everykidinapark.gov to obtain paper passes for each of their students by navigating to the educator section.

San Diego Thornmint (Acanthomintha ilicifolia)

When you are walking, hiking, or biking, be aware of the San Diego Thornmint.  The plant is extremely rare and is on the California endangered species list, and on the Federal Government’s endangered species list.  The San Diego thorn-mint is covered in the San Diego Multiple Species Conservation Plan NCCP.san diego thornmint

So what does this mean? 

In short, it means it is illegal to kill or possess this plant.  Please don’t walk on it, nor crush it!   Sycamore Canyon is one of the few known areas where this rare herb grows.

So what exactly is this plant?

The San Diego Thornmint is an annual that that only occurs naturally in southwestern San Diego County and thornmint2bnorthern Baja California in openings within coastal sage scrub, chaparral, and native grassland.  It grows only on gentle southeast to west facing slopes and blooms April through June.  San Diego thornmint is a small, aromatic annual in the mint family (Lamiaceae) with delicate white and rose colored flowers. The lower halves of its leaves are wedge-shaped and its flower clusters are covered by prominently spined bracts.

Polyphagous Shot hole borer

What is the polyphagous shot hole borer & how much damage can one tiny bug cause?

Akif Eskalen steps through the dense, damp leaves in a wooded neighborhood, scrutinizing the branches around him. He’s looking for evidence of an attack: tiny wounds piercing the bark and sap dried around them like bloodstains.  It is The Polyphagous Shot Hole Borer.    What?  You’ve never heard of it?

The victims are boDavid Fleming uses a pocket knife to dig out a polyphagous shot-hole borer beetlex elders, sycamores and coast live oaks, all in some state of suffering. Eskalen approaches a tree riddled with 1-millimeter holes, as if someone used it for miniature target practice. It’s time to nab a perp. He selects a hole, pulls out a large knife and expertly levers out a chunk of wood.

There, in his hand, is a glossy beetle no larger than a sesame seed:The Polyphagous Shot Hole Borer.

Though small and sluggish, its appetites are wide and its spread is relentless. It attacks forest trees, city trees and key agricultural trees. It has defied all conventional and chemical weapons. No one seems to have a way to stop it.UTI1747472_1_t837

Eskalen tips the beetle into a glass vial. He detaches a pink spray bottle from his backpack and administers a few lethal squirts of ethanol before twisting the vial shut.

These beetles have a strange M.O. They don’t eat wood, like termites; instead, they drill circular tunnels toward the heart of the tree. They carry fungal spores in their mouths and sow them like seeds as they go. Then they harvest the fungus to feed their larvae. It’s a deadly partnership: The beetles attack, but the fungus also helps to kill, colonizing the wood tissue and spreading through the plant.

The Polyphagous Shot Hole Borer. have easily evaded the authorities. Inside the tree, they’re well protected from pesticide sprays. The incestuous offspring mate with their siblings inside the trunk, so sex pheromones do not lure them out.

“If we can’t control them,” Eskalen said, “they are going to wipe out all our trees.”

The consequences of a wide-ranging infestation could be enormous. Common city trees, such as American sweetgum and maple, would become public branch-dropping hazards. Native trees such as the California sycamore and the coast live oak have started to succumb, creating a fire risk in the form of dead, dry tinder. Avocados and other crops could face huge financial losses.

A genetic analysis traced the bugs to Vietnam. Unlike other insects that target just a few species, the shot-hole borer beetle is an equal opportunity pest, infesting at least 286 tree species and posing the potential for widespread destruction.

Its hosts include California natives such as coast live oaks and sycamores, and key agricultural crops, including avocado. The shot-hole borer beetle injects trees with a fungus, which it them “farms” for food. The beetle’s adaptability and wide host range make it tricky to identify, because symptoms of infestation vary among the hundreds of trees it attacks. A handout on Eskalen’s website shows the beetles’ effects on different trees …Some ooze with gummy deposits on their bark… Others display dark or reddish stains on their trunks. …Still others erupt in clusters of crystals called “sugar volcanoes.” The beetles are prolific breeders too, and can lay eggs several times per year, experts said.

“The female will bore into hundreds of typical, common tree species,” Launder said. “In most of those species, the fungus will grow. The fungus is the food source for their offspring. The tree ends up just bleeding.”

San Diego is already battling the gold-spotted oak borer, which has felled thousands of California live oak, black oak and canyon live oak in the backcountry, and in parkland.

The oak-borer beetle spreads on firewood, and apparently hitchhiked that way from San Diego County to the mountain town of Idyllwild, in Riverside County, late last year. Forestry and agricultural officials have urged residents not to transport wood, and say that message is doubly important in light of the new pest.

Known Hosts: The following is a selected list of common landscape trees from more than 110 known hosts: box elder, castor bean, avocado, coast live oak, English oak, valley oak, California sycamore, big leaf maple, Japanese maple, red willow, goldenrain tree, olive, persimmon, silk tree, American sweet gum, coral tree, weeping willow, blue palo verde, palo verde, Chinese willow, white alder.

 

What to do:

  • Look for a single exit hole with surrounding white powderyThe finger points to a beetle entry hole on an avocado trunk. exudates.
  • Scrape off the bark layer around the infected area to see the canker.
  • Follow the gallery to look for the beetle (it may or may not be present).
  • DO NOT move infested wood out of the infested area, including firewood.
  • Look for other hosts (castor bean, box elder, black locust, coast live oak) showing

symptoms of the beetle/disease.

  • There are no effective treatments against this pest/disease complex.
  • If you remove an infested tree, chip it or cut it into firewood and cover with clear

plastic for at least 2 months to kill any remaining beetles.

  • DO NOT move the tree from your property to prevent spreading the beetle and disease.

Who to contact if you find the problem:

If you suspect that you have found this beetle or seen symptoms of the disease on your tree or in surrounding areas please contact either your local Cooperatve Extension Office or Dr. Akif Eskalen by phone 951-827-3499 or email at akif.eskalen@ucr.edu.
