Sound Policy

While most U.S. cities have a tree protection policy, the subsequent impact on the reduction of canopy loss is unclear. To rectify this, I utilize a theoretically grounded framework of influence comprised of clear identification of the problem/public support, adequate resources, and sound policy logic. This is then tested in a comparative case study of Charlotte, North Carolina, and San Antonio, Texas. While Charlotte benefits from public recognition of the problem and adequate resources, its regulations are weak, lacking a logical connection to aspirational outcomes. San Antonio's regulations are stronger, but combined with weaker problem identification and resources. Through quantitative and qualitative assessments, I find that San Antonio's strict regulations may have stabilized loss rates, while Charlotte's weaker rules have not. Results highlight the importance of policy logic over other commonly suggested determinants of natural resource protection.

Educational Potential

Current serious environmental issues, such as deforestation, compel compulsory school education on the need for reflection on pedagogical practices to promote education for environmental sustainability. The educational process about the “tree as living being” requires that content and attitudinal dimensions be deeply integrated. Therefore, meaningful learning of biological similarity—between tree and animal—needs to be prioritised. It will promote the development of tree protection attitudes. Under this approach, an action research was developed to contribute to a future primary teacher education model. A didactic-pedagogical intervention was designed. It was implemented to assess the educational potential of infrared thermography in the development of ecocentric education. A group of students attending the 3rd year of primary education participated in this qualitative case study. The results revealed that ecocentric conceptions were constructed bringing these children closer to scientific knowledge. It resulted in the development of conservation/protection tree attitudinal learning. It is also worth mentioning the contribution of this study to (re)think (re)construction of the formative process of future primary teachers in order to: direct the teaching–learning process to environment real problems; and to promote the necessary debate on the contribution of technology to achieve innovation of pedagogical practices.

Two aerial applications of microencapsulated pheromone were conducted on five 20.2 ha plots to disrupt western pine shoot borer (Eucosma sonomana Kearfott) and ponderosa pine tip moth (Rhyacionia zozana (Kearfott); Lepidoptera: Tortricidae) orientation to pheromones and oviposition in ponderosa pine plantations in 2002 and 2004. The first application was made at 29.6 g active ingredient (AI)/ha, and the second at 59.3 g AI/ha. Baited sentinel traps were used to assess disruption of orientation by both moth species toward pheromones, and E. sonomana infestation levels were tallied from 2001 to 2004. Treatments disrupted orientation by both species for several weeks, with the first lasting 35 days and the second for 75 days. Both applications reduced infestation by E. sonomana, but the lower application rate provided greater absolute reduction, perhaps because prior infestation levels were higher in 2002 than in 2004. Infestations in treated plots were reduced by two-thirds in both years, suggesting that while increasing the application rate may prolong disruption, it may not provide greater proportional efficacy in terms of tree protection. The incidence of infestations even in plots with complete disruption suggests that treatments missed some early emerging females or that mated females immigrated into treated plots; thus operational testing should be timed earlier in the season and should comprise much larger plots. In both years, moths emerged earlier than reported previously, indicating that disruption programs should account for warmer climates in timing of applications. The AIs we tested are behaviorally active for 13 other species of Rhyacionia and six other species of Eucosma, so the approach may have wide application.
