Red Brome Grass Fuels Wildfires in Arizona


May 12, 2006

MESA, Ariz. — With the fire season already upon us, a symposium, hosted by Arizona State University at the Polytechnic campus May 16-17, will open the discussion on how to better control the overgrowth of red brome grass to help reduce the threat of wide spread fires.

"Arizona's landscape has changed drastically because of recent wildfires, like the Rodeo Chedeski, Willow and Cave Creek Complex fires, that burned thousands of acres of land, fueled by red brome," says John Brock, ASU Applied Biological Sciences professor.

Brock says that a minimum of 50 years is needed for the burned sites to recover when a wildfire does occur.

"The desert does not have a fire adapted vegetation type and the character of the Sonoran desert changes greatly after a fire," says Brock. "Sagauros, other cacti, and trees like palo verde have a very high mortality rate to fire."

Symposium attendees include research scientists from the southwest who are in academia and federal research organizations, land managers from federal, state, county and city agencies, and interested public. They will come together to educate each other on the ecological impacts of the exotic annual red brome grass, and its role in the promotion of wildfire in the Sonoran desert.

There is no way to eradicate such a plant from the desert. However, discussions at the symposium will focus on the range of ways to minimize it, from controlled burns to controlled livestock grazing. Part of the program will be devoted to restoration techniques and processes as well.

"During the symposium we will have presentations on natural ways to control the plant with perhaps soil organisms like myco-herbicides, diseases or seed fungi," says Brock. "We probably do not want to eradicate it but to suppress its population to shift the dominance in the community to native species."

Even though it has its negatives, the grass does have some benefits to the desert ecosystem. "When red brome grass is young and tender, desert animals, like quail and desert tortoise, use the grass as a food source," says Brock. "Red brome grass also provides surface cover, so it can help reduce surface soil erosion."

ASU Polytechnic's STAR research center and Applied Biological Sciences department is hosting the event, with support from the Southwest Vegetation Management Association, the Arizona Section of the Society for Range Management, the Nature Conservancy, Tonto National Forest, the Bureau of Land Management, the Natural Resources Conservation Service, and the Federal Interagency Committee for the Management of Noxious and Exotic Weeds.

NOTE: Reporters are invited to attend the event and/or the press conference planned for May 17 at 2:30 p.m., where you will be able to ask questions of the presenters following the meeting.

Tempe Early Reading First Partnership


May 21, 2006

This feature is the second in a series of features highlighting the recipients of the 2006 President’s Medal for Social Embeddedness.

On a Monday evening a diverse group of preschool teachers, assistant teachers, faculty from Arizona State University and the Arizona Literacy and Learning Center (ALLC), and mentors from the Tempe Elementary School District (TESD) gather in the library of Frank Elementary School. The educators socialize, sharing stories of recent successes in teaching preschoolers early reading and writing skills. A few minutes into the proceedings, Dr. Shelley Gray, an ASU assistant professor and researcher in the Department of Speech and Hearing Science, calls the meeting to order.

Her question sparks a lively discussion as mentors and preschool teachers offer their ideas about how teaching skills are acquired and the best ways to instruct children. As these educators from both the university and public school arenas share their knowledge with one another, it becomes clear that this professional development meeting of the Tempe Early Reading First Partnership (TERF) is just one example of how this partnership between the community and ASU is helping set community standards for what constitutes quality, research-based early childhood education.

For the past two years, TERF has been combating Arizona’s literacy crisis by helping preschool teachers serving low-income students develop curricula for enhancing a child’s phonological awareness, vocabulary, alphabet and print knowledge, and expressive language skills. Such skills help children read, write, and communicate better as they grow older. Funded by an Early Reading First Grant from the U.S. Department of Education, TERF members combine their expertise to create the needed curriculum.

Many members experienced growing pains early in the program. “Our first year it was like ‘what are we doing?’” reminisces preschool teacher Chris Zuniga. Fellow teacher Darcey Ryan agrees, comparing the process of creating a new curriculum that could overlap their existing one to being in a “lion’s den.” Gradually the teachers found ways to implement the new curriculum, using games such as bingo to improve a child’s alphabet knowledge, and putting on class plays that make children use new vocabulary words to improve their reading and expressive language skills.

Three times a month, a professional development team of ASU and ALLC staff members provides courses and training sessions for mentors and preschool teachers, sharing the latest research on reading and early literacy curricula. Mentors from TESD pair up and spend a minimum of eight hours a week with preschool teachers from two other TERF participants – Tots Unlimited, a for-profit daycare center, and Maricopa Head Start, a comprehensive program for low-income families. Together, mentors and teachers work in their preschool classes to translate ASU and ALLC research into lesson plans and activities that will fit the needs of their students.

The mentors emphasize that earning the trust of teachers is vital to TERF’s success, as they must critique each teacher’s performance in the classroom. Mentor Rachael Learn finds that modeling teaching skills in front of children helps develop this trust because, “it shows them I’m not going to ask them to do anything that I’m not willing to do myself.” While their support has strengthened teachers’ skills, the mentors also feel that their experience with teachers has honed their mentoring abilities.

With over three hundred and sixty children benefiting from their teachers’ increased expertise, as well as the monetary investment in early literacy materials that have enriched their classrooms, preschoolers gain immensely from TERF. Educators burst with stories about their students’ success and the class walls display many examples of student writing projects. TERF research data confirms this success – test scores show TERF children are “at” or “above” expected bench marks for kindergarten while a high percentage of special needs children no longer require special education services.

As TERF completes the second year of its three-year project, it continues to make an enduring impact on preschool education. To date, eleven preschool teaching teams and administrators have received more than 100 hours of professional development through ASU classes accompanied by 300 hours of in-classroom mentoring. Many teachers will mentor other preschool teachers in the new curricula once the project ends. Teachers also earn undergraduate and graduate credit through TERF by taking ASU professional development courses, inspiring many to pursue a degree and increase their teaching skills. Likewise, the relationships fostered by TERF allow ASU students to volunteer in preschools by assembling teaching materials and assisting students, something that has inspired undergraduate Linda Shadly to become an advocate for early literacy.

“I could not have paid for this experience,” raves Shadly.
