Diddordebau Ymchwil

Ecology, management and ecosystem services of forests and agroforestry systems, with particular emphasis on tropical and upland environments. Biodiversity conservation in protection and production forests; invasive woody species. Forest restoration and remediation of degraded and post-industrial land. Sustainable forest management and policy including: climate change mitigation through carbon sequestration; Reduced Emissions from Deforestation and forest Degradation; reduced impact logging; silviculture; secondary and buffer-zone forest management; community participation; monitoring. Forest ecology including: natural regeneration; resistance and resilience of forests to disturbance (including pathogens and herbivores); succession; landscape; climate change adaptation.  Ecosystem ecology across a range of forest, agroforestry, agricultural and upland land uses: nutrient and carbon cycling; sustainable intensification.

I am happy to consider supervising student-generated projects within the following subject areas: Ecology, management and ecosystem services of forests and agroforestry systems, with particular emphasis on tropical and upland environments. Biodiversity conservation in protection and production forests; invasive woody species. Forest restoration and remediation of degraded and post-industrial land. Sustainable forest management and policy including: climate change mitigation through carbon sequestration; Reduced Emissions from Deforestation and forest Degradation; reduced impact logging; silviculture; secondary and buffer-zone forest management; community participation; monitoring. Forest ecology including: natural regeneration; resistance and resilience of forests to disturbance (including from pathogens and herbivores); succession; landscape; climate change adaptation. Ecosystem ecology across a range of forest, agroforestry, agricultural and upland land uses: nutrient and carbon cycling; sustainable intensification.

    Disgrifiad

    The active phase of the project ran from May 2009 until September 2011 but the valued network of local farmers built-up during this time along with the goodwill and trust shown to project officers by the farmers and their Unions will hopefully live on long beyond the project.

    The results and findings of the project are reported in a project handbook which has been uploaded onto this website and also exists in paper form and can be requested free of charge from: Nia Evans, RDP Project Development Officer, Community Development Service – Rural, CONWY County Borough Council.
