Humboldt State University’s Range Plant Identification team placed 5th in a contest that has been described as one of the toughest in recent memory. Deedee Soto, an HSU Botany major with a range minor, placed 5th in the individual category. Coached by lecturer/NRCS Rangeland Specialist Todd Golder, other team members include Mariah Aguiar, Amanda Albright, Melissa Chase, Axel Sanchez, Eric Garcia, Monica Rodriguez, Steven Gilster, Tess Palmer, Darren Pinnegar, and Kaelie Pena. These students were enrolled in RRS 475 Advanced study of Range Plants, offered every semester.
Most plant species on this test were grasses and many consisted of mere fragments of material. We owe much to HSU’s exce

Faculty David Greene, Jeff Keane & Melanie McCavour Forestry & Wildland Resources

David Greene and Jeff Kane of the Department of Forestry and Wildland Resources and Melanie McCavour of the Department of Environmental Science and Management have just been awarded a 10-year $800,000 grant from the Bureau of Land Management for a study of Baker Cypress. This tree species, restricted to a few populations in northern California and southern Oregon, has seeds retained in cones that will only open when burned and the continuation of fire exclusion is strongly contributing to its potential extinction. The purpose of the grant is to better understand the reproductive ecology of Baker Cypress, determine the feasibility of using prescribed fire and other treatments to inform the restoration and management of this species, and create the Environmental Impact Report that will underpin the management plan.

Student Soil Scientists Forestry & Wildland Resources

Five of six Humboldt State University students (83%) passed the rigorous “Fundamentals of Soil Science” exam offered on April 15, 2011, becoming Associate Professional Soil Scientists, according to tests results from the Council of Soil Science Examiners.

Ten Wildland Soils and four Forest Soils students graduated from Humboldt State University in 2011. Five Rangeland Resource Science students also graduated, one of whom had sufficient soil science courses to be qualified for the federal Soil Scientist position. This means that Humboldt State University graduated 15 fully qualified Soil Scientists, more qualified students than most institutions have enrolled at any given time!

Faculty Sara Hanna and Ken Fulgham Forestry & Wildland Resources

Research by the Department of Forestry and Wildland Resources faculty was recently featured in a special issue of California Agriculture, a quarterly journal of peer-reviewed research from the University of California Division of Agriculture and Natural Resources. The issue titled, Forestry: Managing for the Future highlights a wide range of forestry related research being conducted in California.

Sara Hanna and Ken Fulgham, Lecturer and Emeritus Professor respectively in the Forestry & Wildland Resources Department, had their article on Post-fire vegetation dynamics of a sagebrush steppe community change significantly over time published in California Agriculture, Volume 69, Number 1, January-March 2015. The article summarizes almost 30 years’ worth of data collected on two prescribed wildland fire sites in the Clear Lake Hills area of Modoc County. Significant findings regarding the post-fire plant community trajectories and changes over time have management implications for domestic livestock grazing, interstate mule deer herd winter range use, and the provision of suitable habitat for the threatened Sage Grouse (Centrocercus urophasianus).

Student Whitney Butler, Whitney Schimke, Alexander Taylor, Ryan Camera and Tyler Hullquist Forestry & Wildland Resources

Students and faculty from the HSU’s Department of Forestry and Wildland Resources recently travelled to Albuquerque to take part in professional meetings and compete in the Society of American Foresters (SAF) Quiz Bowl at the society’s annual convention in October.

HSU sent five forestry students, Whitney Butler, Whitney Schimke, Alexander Taylor, Ryan Camera and Tyler Hullquist, to compete. The contest brought together student teams from universities across the country to demonstrate their knowledge in a wide variety of forestry disciplines.

Forestry and Wildland Resources Department Chair Ken Fulgham and Professor Han-Sup Han attended the five day convention, where Fulgham presented a poster titled “Long-term, Post-Fire Dynamics of a Sagebrush Steppe and Western Juniper Community.” It summarized nearly thirty years of post-fire vegetation monitoring of sagebrush rangelands in Modoc County in Northeastern California. Dr. Han participated in the McIntire-Stennis meetings as the HSU-Administrative Technical Representative (AT-R).

Student Crystal Welch, Andrew Longman, Tyler Hanson and Robin Halloran Forestry & Wildland Resources

Three Humboldt State University students passed the rigorous “Fundamentals of Soil Science” exam offered April 17, 2015 becoming Associate Professional Soil Scientists, according to test results from the Council of Soil Science Examiners. Crystal Welch, Andrew Longman and Tyler Hanson were among five individuals in California who attempted the exam this spring and were the only California examinees to pass the exam. Nationally, 61 individuals took the exam with a pass rate of 59% overall according to Michele Lovejoy, Program Manager for Professional Development of the Soil Science Society of America.

Crystal Welch graduated in Fall 2014 with a degree in Rangeland Resource Science (Wildland Soils option). After performing lab analysis of soils for Dirty Business Consulting in Arcata, Crystal starting working as a field scientist for the Great Basin Institute in Reno, Nevada. Andrew Longman graduated Spring 2014 with a degree in Rangeland Resource Science (Wildland Soils option) and will soon begin a position as Junior Specialist for Organic/Conventional Farming Project with Dr. Louise Jackson at U.C. Davis. Andy will help study the effects of water deficits on crop physiology, biology and pests. Tyler Hanson has completed his minor in Wildland Soil Science, and will graduate in Fall 2015 with a degree in Botany. Robin Halloran, another Wildland Soils option graduate (Spring 2015), passed the same exam November 21, 2014. In summary, 16 out of 23 HSU students who have attempted the exam have passed (70%) since 2011, well above the national average pass maximum of 63% for the same time period.

Those who pass the fundamentals exam will be eligible to take the Professional Practice exam after five years of professional experience, an additional step in becoming a Certified Professional Soil Scientist. Recent Soil Science Society of America (SSSA) discussions about program self-certification have included the fundamentals exam as one indicator of program quality. Given that the exam is multiple choice, it does not evaluate students’ field skills per se, but is an exam that is offered nationwide and is therefore ‘portable.’ Humboldt State University Wildland Soils students (an option under the Rangeland Resource Science major) spend more than 200 hours in field or laboratory learning experiences, honing hands-on skills and field judgment of soil properties, limitations, and capabilities.
