Forest sustainability is the foundation of forestry and modern forest management. Originally the central concept was sustained-yield and maximum timber production and then multiple-use and other non-timber values gained importance. After the Rio Conference and development of the Montréal Process in the early 1990’s, forest sustainability rapidly gained importance and various forest certification schemes developed to certify forest products that were grown using sustainable forest management. Forest sustainability and forest certification have become critical topics in forestry curricula. The American Tree Farm System is one of the important North American forest certification organizations. Modern forestry curricula often include a capstone course where forest management plans are developed. We describe a capstone course at Clemson University under development that uses the management standards and management plan template of the American Tree Farm System as a framework for students to develop actual forest management plans for local forest owners. The material is integrated into a series of four courses leading up to the capstone course. The course offered a hands-on approach for students to create management plans using actual certification standards and the system’s management plan template. In addition, students received specialized training to qualify as auditors for the certification system. This is an example of forest sustainability being integrated into the forestry curriculum.

The vast majority of Foxp3^(+)regulatory T cells(Tregs)are generated in the thymus,and several factors,such as cytokines and unique thymic antigen-presenting cells,are known to contribute to the development of these thymus-derived Tregs(tTregs).Here,we report the existence of a specific subset of Foxp3^(+)Tregs within the thymus that is characterized by the expression of IL-1R2,which is a decoy receptor for the inflammatory cytokine *** flow cytometric analysis of the thymocytes from Foxp3^(hCD2)xRAG1^(GFP) reporter mice revealed that the IL-1R2^(+)Tregs are mainly RAG1^(GFP-)and CCR6^(+)CCR7^(-),demonstrating that these Tregs are recirculating cells entering the thymus from the periphery and that they have an activated *** the spleen,the majority of IL-1R2^(+)Tregs express neuropilin-1(Nrp-1)and Helios,suggesting a thymic origin for these ***,among all tissues studied,the highest frequency of IL-1R2^(+)Tregs was observed in the thymus,indicating preferential recruitment of this Treg subset by the *** fetal thymic organ cultures(FTOCs),we demonstrated that increased concentrations of exogenous IL-1β blocked intrathymic Treg development resulting in a decreased frequency of CD25^(+)Foxp3^(+)tTregs and an accumulation of CD25^(+)Foxp3^(-)Treg ***,the addition of IL-1R2^(+)Tregs,but not IL-1R2^(+)Tregs,to reaggregated thymic organ cultures(RTOCs)abrogated the IL-1β-mediated blockade,demonstrating that these recirculating IL-1R2^(+)Tregs can quench IL-1 signaling in the thymus and thereby maintain thymic Treg development even under inflammatory conditions.
