Trophic State: A Useful Scale for Classifying Lakes Based on Biological Productivity

Elizabeth Duermit Moreau

Lakes are diverse and come in all shapes and sizes. The Trophic State Classification System allows people to group waterbodies into one of four categories, called “trophic states,” based on their level of biological productivity. Knowing what these terms mean can help you understand how your waterbody compares to others, and what changes in its water quality over time could mean. This publication explains how water chemistry is used to determine a waterbody’s trophic state; what criteria are used to define the four trophic states; which trophic state category your waterbody fits into; and how the Trophic State Classification System can be useful.

The Value of 4-H to Youth in Florida and Beyond

Keith G. Diem

To maximize the strengths of the 4-H Youth Development Program and to promote its value to the public and funding agencies, Extension staff must know the value of 4-H as it is perceived by others. Since parents are key stakeholders in the 4-H program because they approve of their children being members and they are taxpayers and voters, this descriptive survey research involving a randomly selected sample of parents of 4-H club members in Florida aimed to determine what value 4-H brings to youth members, what problems 4-H faces, and what other beliefs parents have about 4-H.

Promising Practices for Working With Youth With Disabilities

Vanessa Spero, Darcy Cole, Vera Bullard, Jennifer Cushman, Tara Dorn, Kelsey Dugan, Crystal Perry, and Jennifer Taylor-Winney

The most recent data from the National Center for Education Statistics report that 15% of individuals aged 3–21 are served under the Individuals with Disabilities Education Act. This means that 15% of youth are diagnosed with a disability that has the potential to affect their success academically and in the workforce. As a youth development organization, 4-H programs should anticipate at least 15% of their population, if not more, to have a diagnosed disability. As youth development professionals, we are tasked with meeting the needs of youth with disabilities through proactive and reactive planning strategies. This also includes professionals being flexible, accommodating, and ready to foster Positive Youth Development best practices.
